I just bought one 2001 Buick LeSabre from this old lady she wanted 1000 dollars for it it has 62,000 miles on it I gotten a good deal. It's was maintain good enough with this low miles I'm happy !
My first car. Raced my friends in highschool, set it sideways in snowy parking lots, did burnouts on shit tires, Lost my V-card to the weird girl in class in the front seat. Most underrated car ever built. The 3800 was just quick enough to be fun, always sounded good, got starved of oil all the time due to it being a beater and never complained ever. I still own it even though it’s a farm car now. Hats off to Buick man. They don’t build all American beef like this anymore
A few (hopefully useful) notes: 1. The coolant elbows mentioned in this video should be replaced with the aftermarket (metal ones). 2. Front subframe bushings tend to go bad and aftermarket replacements seem to last for some five years. The problem with these bushings are causing obvious suspension problems but usually are overlooked and not included in the scope of things to be checked. 3. Rear subframe (front) bushings do go bad and there's no replacement for them. To do the repairs you may want to cut a couple of corresponding size washers from and old tire (worked for me on two cars, but it's on your own risk). 4. Often problem is the leak in the vapor storage system which appears as the gas cap not being closed tightly. If the new can is not available the system can be patched with a 'plumbing' tee. 5. Oil dipstick tube being in front of the engine tends to rust to the holes - consider checking and replacing it. 6. Consider changing tranny/engine mounts - at least on the left and right of the car. The engine is hanging on them so if they go you may be in trouble. 7. If you plan to keep the car consider replacing the brake lines with copper nickel (cunifer) tubing. 8. Replacing rear struts with coilovers is a good idea not because the air struts are expensive - they are not, but the compressor and the height sensor will cost more than the car. 9. Do rustproofing regularly.
With the coolant elbows, replace them with the METAL version, not the plastic. The plastic works for a while, but the metal versions last longer, and won't melt, like the plastic can do, which distort, then begin leaking.
I’m on my 4th Lesabre. These are the absolute best cars I have ever owned, of over 110 previous vehicles. Incredibly reliable, very easy to work on, parts are easy to get. Not to mention the comfort and the exceptional fuel economy in a car this size. Why am I on my fourth and not still on my first? People wanted to buy them. Fun fact. All 4 of mine have been 2002’s and beige by coincidence. I really want dark red with tan leather.
I just bought a 2004 with 61k miles. It did some sitting but know it's a great car and replacing a 2000 with green to burgundy or maroon color with leather seats. I only have wear on the driver's seat. Keep looking for it
I’m debating buying a 02 with 174k miles but needs an intake manifold. It’s not leaking coolant yet do you think it would be okay to drive it to my house around 25 miles? No way to tow it.
when you have the upper plastic manifold crack and flood the engine with coolant, make sure to replace the EGR valve chimney in the lower manifold to the updated skinnier one to keep some of the heat away from the plastic to prevent future failure
Have an 04' limited with 200k on the dash. No check engine light, an I drive 40 mile commute every day. Encountered all of these and then some. Gas gauge doesn't work, window on front passenger side gets crooked when going up, speakers are blown/rotted. (Wish it had a bit more power) Either way I love this car. It's never left me stranded.
Have a 2000, a ghost turns on the radio on occasion. I listen to it loud, but when it's comes on by itself loud, darn. The wipers also come on by themselves, they act erratic otherwise.
You know that could be a fuel sensor access port to fuel tank is in the back of the trunk underneath the cloth covering has like 5 or 6 bolt plate can pull the fuel pump and sensor out without the tank having to be dropped
My gas gauge shows full then suddenly drops to empty and the warning light comes on. Then right back to full. LOL. I go by my trip odometer. Every 300 miles fill it up. It’s a tank.
On a Buick LeSabre... If you push the 'Cruise Control' button and nothing happens (no amber light on in the on/off button) the easiest and therefore the FIRST thing to check is the #14 fuse in the fuse-box under the hood. If that is not the problem, the SECOND thing is check fuses under the steering column. (Under the steering wheel, about where your left knee is when driving). Remove the plastic cover panel (it just pulls off), then remove the steel plate that is under that panel (just four 10mm screws). There is a small black rectangular plastic box with wires sticking out of it. Open the box and you will find three 2 AMP fuses. Check these for a burn-out. They control the lights/function of the buttons on your steering wheel. AND they are not mentioned in the owners manual. This job takes about 10 minutes to do, and it will save you hours or even days of frustration. (I just fixed my own 2004 Buick Lesabre this way; and also fixed a friends 2001 Lesabre this way; so I'm guessing they all have these 2 amp fuses under the steering column).
I own a 2005 lesabre...I have had all 5 of these issues! Others issues I've fixed... Front away bar links Rear stabilizers Power steering pump Next up.... Headliner Battery Instrument cluster lights ... if I smack them they come back on. Been doing that for 2 years... need to fix I love this car! I think it's one of the best out there! 179k so far
I also have a 2005 Buick LeSabre except it has over 126K miles on it but the engine & transmission is great. I bought it recently from a used car dealer for only $2K. I had to replace the windshield, renew the break rotors, replace tie rod & a few other minor issues. Other than that, it's running great now.
kind of surprised that the EVAP purge solenoid didn't pop up. had to swap that out at 110k miles because it was stuck open causing an evap leak code. i even tried getting a new OEM gas cap first because i saw that was a common thing. 35 bucks and 3 minutes and the code went away.
You won't believe this but currently I'm parked in between two of those vehicles as we speak. LOL I'm in my driveway my roommate has one and then came across another to use as a parts car. somehow today I got sandwiched in between them lol. I'm getting ready to share this video with her as we speak LOL BTW why do these cars sit so low to the dang ground?
I know a lot of times when people buy these used the first thing they gotta do is get those old rotten brake lines off the car and replace them.....I just did that with mine, instead of trying to fix this line or that I just pulled them all off and replaced the whole thing...
We have a 2005 lesabre. Problems we’ve had with it are the ignition module (which is common on any 3800 engine) . That problem should have been listed. blower motor resistor, and the rear air ride shocks did go bad a few years ago. They were leaking causing the pump to kick on so often Also another common issue with these Lesabres and any GM vehicle with the 3800 v6 is more often the catalytic converters will lose their efficiency and trip a P0420 code for inefficient catalytic converter

Also consider checking the lower subframe bushing ,driver side. Lower intake gasket, kits are available, add sealant for bolts to prevent oil coming up into the upper intake manifold.
The toughest job will be switching out the Pressure solenoid, but once you drop the cradle and lower your engine a bit ( have a cross member of some sort to hold up the engine) its all gravy.
I just purchased a 2001 Buick Regal, fully loaded with all options and it has only 27000 original kms. looks and drives , smells like brand new for my wife. Hope she has good luck with this beauty ///
These are basic vehicle problems these cars ive seen em last 300k even 400k once easily get 250k to 300k out of these cars the toyota of gm wat i like to call em
I worked as a gm tech for quite a few years, majority of these came in as elderly folk cars. These things ran really good for a while. The engines in these last a while once u continue with basic maintenance
2002 Lesabre - All the above plus all window regulators twice, cruise control switch, headlights switch, fuel pump, tie rod ends, control arms, upper ball joints, and transmission is starting to slip. All these failures occurred well before 100k miles. But drives like a dream.
"Drives like a drives like a dream" You must be sarcastic after listing all those issues? I had an 02 Toyota 4runner with 230k miles. I only replaced a radiator cap and 1 02 sensor. That was the definition of a dream... Not replacement of EVERYTHING 😌
Agreed I've owned many different buicks and absolutely love them the lesabre especially cause that's what I grew up with my grandma had one but I've had a 93 and 94 buick century specials and a93 roadmaster not the lt1 just the tbi and a 93 90th anniversary lesabre custom 96 lesabre limited and a 99 lesabre limited newer vidystyle from 97to 99 and a 2000 lesabre limited and a 2002 century custom and just from experience the old body style lesabre and centrum and park Avenue are much more reliable cars the cars themselves cause they have the same engine but they had the crappier 4t60e and the 97 and up had 4t65e neither are that great but they are ok if taken care of but the 3800 wont die the 3300 wont die and the 3100 is powerful but questionable when it comes to reliability but the old bodys dont fall apart like the newer next gen body styles they called them the had great powertrains but they just fell apart and I'm a huge buick fan just have a soft spot for them and their quirks it's just fun to drive and own them
@@testosteroneinc.3800 what I mean by “drives like a dream” is smooth control and ride when driving. None of the things I listed kept it from being pleasant to drive just not pleasant to own.
Lol I have a 2002 and have had all the problems you mentioned except transmission (knock on wood). But it is a great car and I love it. Overall very reliable. Hard to change the air shocks to coilovers?
Did someone already mention the power window motors? Going through my 2002 LeSabre service records it looks like the previous owner replaced the driver, front passenger and driver side rear passenger window motors when she owned the car. She also had the intake gasket replaced and the radiator elbow were replaced with metal ones. I replaced the MAF sensor and gas cap since I've owned the car. A very reliable car overall.
Got a 2005 LeSabre Limited with 61k miles. Great driving car, but has some glitches. One weird thing is when it's really cold outside, well below freezing, the exhaust gets loud inside the car. I think the exhaust pipe is coming into contact with the floor pan or something and that transfers both sound and vibrations to the interior of the car. Makes it sound like I don't have a muffler. I'm not sure if it's loud to someone on the street, but very loud inside the car. I took it to the shop, but of course that day the temp was above freezing, so it sounded normal and they couldn't reproduce the problem.
I also have a 2005 Buick LeSabre except it has over 126K miles on it but the engine & transmission is great. I bought it recently from a used car dealer for only $2K. I had to replace the windshield, renew the break rotors, replace tie rod & a few other minor issues. Other than that, it's running great now.
Great video. I have one we inherited, and they're great vehicles. I only experienced the blower motor needs to be replaced, and need to do that tomorrow. I wrote down verbatim the other four problems and will keep it in the car for reference. THUMBS UP, THUMBS UP, THUMBS UP!!!!!
Do you know where I can find a video that shows me how to replace a power steering line for a 2000 Buick Lesabre? It's the line that comes directly out of the power steering pump and goes around the frame on the front of the car and back up behind the driver side wheel well. I can't find anything on it anywhere.
My 2004 lesabre overheated 1st week I got it & blew elbows. Got the aluminum replacements. It ended up being fan relay, but found out later the big problem was 2 long silver bolts in the center that hold the fuse box in place were loose. Once I tightened them, I never had a problem with it again.
262,000 on my 2003 Buick LeSabre Limited in light blue. It's been a great car for me. Very comfortable, lots of power when you need it and I get 31 mpg on the highway at 70 mph.
I am needing a second vehicle for commuting back and forth to work and have thought about both new or newer vehicles but for some reason, there have been a ton of lower mile LeSabre for sale in my area. My grandfather had 6th, 7th, and an 8th gen models, he loved them to death! Sometimes two of each generation, one after another because he would trade them the second they hit 100k miles (he drove a lot). I have many fond memories riding in his LeSabres growing up. He would take me out to eat for lunch every two weeks during the winter and to his summer cottage when it was nice out. In all honesty, I think it would be a TON of fun to own for nostalgic reasons.
Thanks for getting right to the information. Some of these guys spend half the video telling you what they are going to tell you even though it's right there in the video title. So this alone got me to hit the Subscribe button.
After fixing the issue with inexpensive improved aftermarket parts i.e. metal intake plenum, coolant elbow, the car is bullet proof and will go 400,000k with proper maintenance.
@@samuelvetromile5382 My 2002 had rust holes behind the front subframe and the frame around the rear spring mounts was almost completely gone. Probably why they still got 30 mpg on the highway, the frame was so thin.
Is there an easy black and white way to tell if the intake plenum and gasket is bad, or the lower intake manifold gasket is bad? The video doesn't even mention the lower intake gaskets. I suspect the intake plenum and gasket is mostly prone to failure, if they haven't been replaced yet.
I had many of these. Frim 2000 to 2002 i had 5. No problems this guy says. The elec windows are the worst feature. He doesnt mention dont think he knows these cars.
my 2000 Lesabre I bought in 2016 from an elderly family member with 60k on it went another 6yrs. to 134k miles with almost no issue..... very reliable car... The salty winters of Rochester , NY were catching up with the body so I just bought a super clean out of State 2005 with 80k on it.... life is good.
Pressure Control Solenoid. Another way to be sure your having the same problem is if the car runs fine for about 30 mins then starts having the hard shift from 1st to 2nd gear, its the Electronic Pressure Control solenoid. another way is is you have the car parked on a flat surface & at normal operating temp, put foot on the brake, move the shift level down from park into drive and if the front of the car bumps/shakes noticibly, its the EPC solenoid.
Miss some issues dash comes lose from windshield and passenger side next to the glove box . Front window tracks are junk. Only good thing about this car is only the motor.
Hey 1a Auto great video. Can you give more detail about the pressure control solenoid. I didn't catch what you said entirely do you have to replace it or something. My 2003 Buick LeSabre is giving me the same problem as it shifts hard. I want to try and see if that is the problem because transmission replacement/rebuild is expensive. Thanks
I have a 2005 Buick lesabre , my exhaust pipe smokes very bad sometimes when I drive off from stop sign, sometimes my dashboard lights will dim and bright up again, vibration in steering wheel when going 80+mph and when braking and my headlights stays on while driving in day time, and sometimes a weird noise from under car sounds light air coming out a tire does anyone knows what could be the problem?
I have a 2002 Regal and it has all the same problems haha. Replaced blower motor/resistor. Front wheel bearings starting to go, and I’m pretty sure my intake is leaking oil. Also rabbits got into mine and chewed up a bunch of the wiring…..
Problem Area #5 really should be the HVAC actuator motor. It's pretty hard to find a LeSabre from that generation that isn't having problems with those actuator motors. Another very weak spot is the forward motor mount from the drivetrain to the cowl underneath the radiator. Those motor mounts blow out in a measley seven or eight years after the car is built. The irregular surface of the city streets cause premature wear and that motor mount will blow out in quick time. They are reliable cars but I wouldn't buy another because of so many other issues that these cars have. Rust, ring gears, tire wear...
I was looking at a used vehicle but I will pass on this Buick. I miss the days of a simple rear-wheel drive vehicle that can be fix with a screwdriver and a book of matches. The supposed reliability is not worth the risk and expense of a big break down for a guy with no longer anything close to being a Mechanic.
You mentioned the blower motor but didn't also mention on the interior the dashboard curls up. I know... I know, that is more aestetics than anything, but try to find a LeSabre from that era that doesn't have curled up dashboard... even the one in your video at the end.
A few years ago I bought a 2000 Buick Century, which is similar to the Lesabre , used that was in mint condition with only 30k on it from a old couple , it ran great with no problems till 56k miles then I had every one of those problems all happen in a short time span of each, first was the leaking intake manifold, next was the hard shifting of the transmission, the radio/CD quit working, the front wheel bearing started making noise along with bad tie rods ,power window controls, , then the lower rocker panels along both sides of the car began to rust out badly , the rest of the car and frame was good ,only the lower part of the body, I was considering fixing the problems but then the brakes lines all rusted and leaked and the car was undriveable , I sold it at a great loss, because the repairs were more than the car was worth, it was the worst car I ever owned from repair expenses and build quality , One thing I did not like about it , the suspension was really soft and would easily bottom out if there was a dip in the road or leaving a parking lot that had a slight drop off near the road , but it had a nice floating type of ride on the highway due to that soft suspension, Overall I really liked the car , nice ride, power, comfort but too much of a money pit
Every single one that I have seen, has the AC not working, seems to be the biggest issue in my area, other than that its engine 3800 V6 is bullet proof.
My mother has a 2004 model and the gas intake receptacle is rusty and leaves a streak line of rust down body of side of car underneath where gas cap is located and a lot of cars have the same problem
What about when driving at 50mph theres a slight shakung like a tires not balanced correct then smooths out after speeding up. I was told the car sat a while
The spring supports in the rear also like to rot out as well as the dog legs behind the rear doors. All of which can be prevented with yearly lanolin treatments.
I was driving one two days ago and the car kept accelerating no matter what I did it was stuck wide open almost wrecked it! Got it parked and the gas pedal was not working correctly it has to have a broken cable and it must have wrapped around somewhere and stuck the gas wide open so dangerous
This is a timely video, I am going to check a 2000 Buick LeSebre tomorrow for me to use to go to work and back home. I am hoping to get a good car for that reason. Thank you so much for the tips! I hope you have videos on how to maintain your Buick LeSabre as well. I pray more success to your channel. God Bless you! :)
My brother just gave me his. 138k 2000, seems fully loaded. Only problem is an intermittent crank no start but so far it’s been great to me. I tightened down the fuse box and he replaced nearly every fuel line component and it still was mean to him. Fuse box was not loose but another vid said it does need to be tightened down to ground properly.
Looks like a laid back granny who is getting ready to take a nap on the rocker. Personally I think these cars look very good. Even by today's standards. Well, the 7th gen anyways. Not so much the 8th gen.
Excellent video.really helpful. Looking for advice. 2004 Buick Lesabre 98k mi. Reg trans shop changed fluid/ filter /Lucas trans fix. found nothing wrong since no Trans codes. Shift is barely felt. More at lower gears. It starts when engine is warmed up.
I love my Buick Regal LS. I replaced the lower intake gaskets, upper plenum, pressure solenoids, both shift solenoids, spark plugs, and harness. I love the ride, and love the 3800z
I have a 2003 Lesabre and it shifts a little rough, I would get the transmission solenoid fixed but I live in AZ and you can't get nothing done here without garages telling you it's going to be thousands of dollars
Eh you would be surprised how cheap those motors are labor cost on them for the most part are pretty cheap and seeing how this motor was used across all GMs car lines that had 6cyl at the time parts are easy to find and widely available which me cost is also cheaper than most other cars of those years

BTW why do these cars sit so low to the dang ground?
i mean people pay big dollars for lowering springs, this just do it for you!
It was designed for older people...so it is lower,and it is heavy,so if the shocks are worn,or that air ride is dead,it will hang very low. 😅
Because it helps smooth out the experience

I worked as a gm tech for quite a few years, majority of these came in as elderly folk cars. These things ran really good for a while. The engines in these last a while once u continue with basic maintenance
2002 Lesabre - All the above plus all window regulators twice, cruise control switch, headlights switch, fuel pump, tie rod ends, control arms, upper ball joints, and transmission is starting to slip. All these failures occurred well before 100k miles. But drives like a dream.
"Drives like a drives like a dream"
You must be sarcastic after listing all those issues? I had an 02 Toyota 4runner with 230k miles. I only replaced a radiator cap and 1 02 sensor. That was the definition of a dream... Not replacement of EVERYTHING 😌
Agreed I've owned many different buicks and absolutely love them the lesabre especially cause that's what I grew up with my grandma had one but I've had a 93 and 94 buick century specials and a93 roadmaster not the lt1 just the tbi and a 93 90th anniversary lesabre custom 96 lesabre limited and a 99 lesabre limited newer vidystyle from 97to 99 and a 2000 lesabre limited and a 2002 century custom and just from experience the old body style lesabre and centrum and park Avenue are much more reliable cars the cars themselves cause they have the same engine but they had the crappier 4t60e and the 97 and up had 4t65e neither are that great but they are ok if taken care of but the 3800 wont die the 3300 wont die and the 3100 is powerful but questionable when it comes to reliability but the old bodys dont fall apart like the newer next gen body styles they called them the had great powertrains but they just fell apart and I'm a huge buick fan just have a soft spot for them and their quirks it's just fun to drive and own them
@@testosteroneinc.3800 what I mean by “drives like a dream” is smooth control and ride when driving. None of the things I listed kept it from being pleasant to drive just not pleasant to own.
Oil pressure switch
Lol I have a 2002 and have had all the problems you mentioned except transmission (knock on wood). But it is a great car and I love it. Overall very reliable. Hard to change the air shocks to coilovers?
Oh, you should mention window regulators. Horrible on this car. Have changed all of them, a couple more than once.
I have an 02 as well I’ve had the same window problem and the fuel sending unit went out
@@davidwarn1 that's why you get the 7th gen, not the 8th gen LeSabre. Better car in every way.
Just bought one, 2004 lesabre with 33k on it, drives beautifully
Did someone already mention the power window motors? Going through my 2002 LeSabre service records it looks like the previous owner replaced the driver, front passenger and driver side rear passenger window motors when she owned the car. She also had the intake gasket replaced and the radiator elbow were replaced with metal ones. I replaced the MAF sensor and gas cap since I've owned the car. A very reliable car overall.
Got a 2005 LeSabre Limited with 61k miles. Great driving car, but has some glitches. One weird thing is when it's really cold outside, well below freezing, the exhaust gets loud inside the car. I think the exhaust pipe is coming into contact with the floor pan or something and that transfers both sound and vibrations to the interior of the car. Makes it sound like I don't have a muffler. I'm not sure if it's loud to someone on the street, but very loud inside the car. I took it to the shop, but of course that day the temp was above freezing, so it sounded normal and they couldn't reproduce the problem.
I also have a 2005 Buick LeSabre except it has over 126K miles on it but the engine & transmission is great. I bought it recently from a used car dealer for only $2K. I had to replace the windshield, renew the break rotors, replace tie rod & a few other minor issues. Other than that, it's running great now.
Wow I almost had everyone of these except the blower and baring's so far anyway.
Man I have had to fix all 5 problems. Would have saved a ton of time watching this. Currently fixing number 1.
Love my Buick LeSabre, I am experiencing what I believe to the the solenoid. Jerks when my rpms get to 2000.
Great video. I have one we inherited, and they're great vehicles. I only experienced the blower motor needs to be replaced, and need to do that tomorrow. I wrote down verbatim the other four problems and will keep it in the car for reference. THUMBS UP, THUMBS UP, THUMBS UP!!!!!
Do you know where I can find a video that shows me how to replace a power steering line for a 2000 Buick Lesabre? It's the line that comes directly out of the power steering pump and goes around the frame on the front of the car and back up behind the driver side wheel well. I can't find anything on it anywhere.
There are aluminum replacement elbows for the 3800, which only costs a few bucks more, that lasts longer than the plastic ones
My 2004 lesabre overheated 1st week I got it & blew elbows. Got the aluminum replacements. It ended up being fan relay, but found out later the big problem was 2 long silver bolts in the center that hold the fuse box in place were loose. Once I tightened them, I never had a problem with it again.
The plastic ones tend to last quite a while too. On both of my Lesabres they were not cracked and one had over 200k miles.
262,000 on my 2003 Buick LeSabre Limited in light blue. It's been a great car for me. Very comfortable, lots of power when you need it and I get 31 mpg on the highway at 70 mph.
i have a 2001 limited after 15 to 20 min driving it has a hard shift from 1st to second 2nd to third. 145000 miles im wondering if its worth fixing?
I have a 2004, and the instrument cluster has gone out for the second time after being replaced. What's up with that?
I am needing a second vehicle for commuting back and forth to work and have thought about both new or newer vehicles but for some reason, there have been a ton of lower mile LeSabre for sale in my area. My grandfather had 6th, 7th, and an 8th gen models, he loved them to death! Sometimes two of each generation, one after another because he would trade them the second they hit 100k miles (he drove a lot). I have many fond memories riding in his LeSabres growing up. He would take me out to eat for lunch every two weeks during the winter and to his summer cottage when it was nice out.
In all honesty, I think it would be a TON of fun to own for nostalgic reasons.
Thanks for getting right to the information. Some of these guys spend half the video telling you what they are going to tell you even though it's right there in the video title. So this alone got me to hit the Subscribe button.
If you have a 1 to 2 slip. How can you tell whether it is the transmission or the pressure control solenoid?
After fixing the issue with inexpensive improved aftermarket parts i.e. metal intake plenum, coolant elbow, the car is bullet proof and will go 400,000k with proper maintenance.
I'm surprised the oil sending unit didn't make this list
Doesn’t seem like a lot
Its a lot of work. Ive Done it to my Buick Regal LS
Is there much of a difference in the " ride" if I exchange the air ride rear shocks to coil-over shocks? How long do air ride shocks normally last?
I switched to air shocks in my 02, they ride smooth
A1 auto has theeeeee best and most simple videos ever. Thanks.
Rust was also a killer. Honestly I can’t remember the last time I saw one of these in the road, I live in the rust belt.
I’m lower in the rust belt and see several a day lol, but yeah they do rust pretty bad
The frames rust out on these
@@samuelvetromile5382 My 2002 had rust holes behind the front subframe and the frame around the rear spring mounts was almost completely gone. Probably why they still got 30 mpg on the highway, the frame was so thin.
I live in Ohio and rust in very bad and I have the same lesabre in this video and mine is almost rust free
I’ve started paying more attention and I have seen a few in the last month.
Is there an easy black and white way to tell if the intake plenum and gasket is bad, or the lower intake manifold gasket is bad? The video doesn't even mention the lower intake gaskets. I suspect the intake plenum and gasket is mostly prone to failure, if they haven't been replaced yet.
Upper intake coolant leak is another one
I had many of these. Frim 2000 to 2002 i had 5. No problems this guy says. The elec windows are the worst feature. He doesnt mention dont think he knows these cars.
my 2000 Lesabre I bought in 2016 from an elderly family member with 60k on it went another 6yrs. to 134k miles with almost no issue..... very reliable car... The salty winters of Rochester , NY were catching up with the body so I just bought a super clean out of State 2005 with 80k on it.... life is good.
Pressure Control Solenoid. Another way to be sure your having the same problem is if the car runs fine for about 30 mins then starts having the hard shift from 1st to 2nd gear, its the Electronic Pressure Control solenoid. another way is is you have the car parked on a flat surface & at normal operating temp, put foot on the brake, move the shift level down from park into drive and if the front of the car bumps/shakes noticibly, its the EPC solenoid.
Miss some issues dash comes lose from windshield and passenger side next to the glove box . Front window tracks are junk. Only good thing about this car is only the motor.
what is the gas milage for a 2002 Buick LeSabre I only get 20 to22 MPG
You forgot fuel pressure regulator on the fuel rail. It can crack the upper intake manifold when fuel leaks in through the vacuum line and ignites.
Hey 1a Auto great video. Can you give more detail about the pressure control solenoid. I didn't catch what you said entirely do you have to replace it or something. My 2003 Buick LeSabre is giving me the same problem as it shifts hard. I want to try and see if that is the problem because transmission replacement/rebuild is expensive. Thanks
I have a 2005 Buick lesabre , my exhaust pipe smokes very bad sometimes when I drive off from stop sign, sometimes my dashboard lights will dim and bright up again, vibration in steering wheel when going 80+mph and when braking and my headlights stays on while driving in day time, and sometimes a weird noise from under car sounds light air coming out a tire does anyone knows what could be the problem?
I have a 2002 Regal and it has all the same problems haha. Replaced blower motor/resistor. Front wheel bearings starting to go, and I’m pretty sure my intake is leaking oil. Also rabbits got into mine and chewed up a bunch of the wiring…..
My 05 lesabre keeps stalling on me. No check engine light. It could be so many reasons why it's stalling. Very frustrating
Problem Area #5 really should be the HVAC actuator motor. It's pretty hard to find a LeSabre from that generation that isn't having problems with those actuator motors.
Another very weak spot is the forward motor mount from the drivetrain to the cowl underneath the radiator. Those motor mounts blow out in a measley seven or eight years after the car is built. The irregular surface of the city streets cause premature wear and that motor mount will blow out in quick time.
They are reliable cars but I wouldn't buy another because of so many other issues that these cars have. Rust, ring gears, tire wear...
seriously... number one head gaskets. aluminum heads, iron block. temperature differential. these are quite good engines but they blow head gaskets.
I love this car, I got a rear air shock issue right now will be fixed in the morning
I have a Buick lessabre limited 2001 only 8500 original miles 2nd owner bought from my grand pa he was 1 owner
He forgot to mention the leaking fuel vapor through the fuel pressure regulator
Nice job I liked it very well presentation slow and to the point
I was looking at a used vehicle but I will pass on this Buick. I miss the days of a simple rear-wheel drive vehicle that can be fix with a screwdriver and a book of matches. The supposed reliability is not worth the risk and expense of a big break down for a guy with no longer anything close to being a Mechanic.
I have a 2000 buick my sunroof won't close can't find the correct fuse for it... can't find it please help
You mentioned the blower motor but didn't also mention on the interior the dashboard curls up. I know... I know, that is more aestetics than anything, but try to find a LeSabre from that era that doesn't have curled up dashboard... even the one in your video at the end.
Just purchased a 2005 Buick lesabre any suggestions?
Is crazy because them is all the problems. I’m dealing with right now. In the shop. 😵💫
A few years ago I bought a 2000 Buick Century, which is similar to the Lesabre , used that was in mint condition with only 30k on it from a old couple , it ran great with no problems till 56k miles then I had every one of those problems all happen in a short time span of each, first was the leaking intake manifold, next was the hard shifting of the transmission, the radio/CD quit working, the front wheel bearing started making noise along with bad tie rods ,power window controls, , then the lower rocker panels along both sides of the car began to rust out badly , the rest of the car and frame was good ,only the lower part of the body, I was considering fixing the problems but then the brakes lines all rusted and leaked and the car was undriveable , I sold it at a great loss, because the repairs were more than the car was worth, it was the worst car I ever owned from repair expenses and build quality , One thing I did not like about it , the suspension was really soft and would easily bottom out if there was a dip in the road or leaving a parking lot that had a slight drop off near the road , but it had a nice floating type of ride on the highway due to that soft suspension, Overall I really liked the car , nice ride, power, comfort but too much of a money pit
Every single one that I have seen, has the AC not working, seems to be the biggest issue in my area, other than that its engine 3800 V6 is bullet proof.
Just bought the 2003 Park Avenue, no air. And the blower motor sounds like a lawnmower... Going to address that shortly.
1. It’s 20 years old. 2. It’s a Buick. Fill in the other 3 yourselves.
Best cars ever made...Buick.
My mother has a 2004 model and the gas intake receptacle is rusty and leaves a streak line of rust down body of side of car underneath where gas cap is located and a lot of cars have the same problem
What about when driving at 50mph theres a slight shakung like a tires not balanced correct then smooths out after speeding up. I was told the car sat a while
Why does the video show you working on the rear tire while explaining the problem with the front wheel bearings??
You're pointing to the front valve cover gasket but it's a V6. What the hell do you do in the back?
The spring supports in the rear also like to rot out as well as the dog legs behind the rear doors. All of which can be prevented with yearly lanolin treatments.
I was driving one two days ago and the car kept accelerating no matter what I did it was stuck wide open almost wrecked it! Got it parked and the gas pedal was not working correctly it has to have a broken cable and it must have wrapped around somewhere and stuck the gas wide open so dangerous
This is a timely video, I am going to check a 2000 Buick LeSebre tomorrow for me to use to go to work and back home. I am hoping to get a good car for that reason. Thank you so much for the tips! I hope you have videos on how to maintain your Buick LeSabre as well. I pray more success to your channel. God Bless you! :)

I've noticed a lot of electrical issues with GM vehicles. Especially the cluster
My brother just gave me his. 138k 2000, seems fully loaded. Only problem is an intermittent crank no start but so far it’s been great to me. I tightened down the fuse box and he replaced nearly every fuel line component and it still was mean to him. Fuse box was not loose but another vid said it does need to be tightened down to ground properly.
Big problem with my 2005 is rain getting in the fuel door
I have 3 of those top 5! Great tip for grabbing the spring to check the bearing.
I have the same car and my steering wheel shakes while In park what could be the issue ?
Sounds like typical Gm problems.
I’ve had the elbows break on my 2004 Lesabre
I got a water pump and new belt,but it is leaking water and it's called the top where is that located
This is only a cosmetic issue, but my 03 LeSabre’s dashboard is peeling horribly. I’ve seen it’s pretty common.
I hardly ever see that where I live. WA. Then again it's probably caused by not washing your car or waxing it.
You named 4 out of the 5 things done on my car.
My worst problem was a wire going to to crank sensor.
Easy fix, nightmare to figure out.
The Cam sensor will go next.Hard to figure because no code or check engine light goes on both parts made in Mexico so pretty inexpensive to replace
The air ride in my lesabre is so clapped out 😂 the floor of my car hits the ground if I go over huge bumps
Rockauto. $88 for the pair, shipping included. So easy to change.
Air flow won’t change from defroster to vents
The front of the car looks like a very disappointed mother
Looks like a laid back granny who is getting ready to take a nap on the rocker. Personally I think these cars look very good. Even by today's standards. Well, the 7th gen anyways. Not so much the 8th gen.
Or you can get almost any new car with the angry Ninja scowl.
Oh! OH! Already had to deal with the wheel bearings!
3800 baby!!!! 😁👍
Excellent video.really helpful. Looking for advice. 2004 Buick Lesabre 98k mi. Reg trans shop changed fluid/ filter /Lucas trans fix. found nothing wrong since no Trans codes. Shift is barely felt. More at lower gears. It starts when engine is warmed up.
I love my Buick Regal LS. I replaced the lower intake gaskets, upper plenum, pressure solenoids, both shift solenoids, spark plugs, and harness. I love the ride, and love the 3800z
Alot less issues with these cars than with new ones.
I have a 2003 Lesabre and it shifts a little rough, I would get the transmission solenoid fixed but I live in AZ and you can't get nothing done here without garages telling you it's going to be thousands of dollars
+Victory Transparency Thanks for checking us out! 1aau.to/m/Shop-1AAuto-c
Eh you would be surprised how cheap those motors are labor cost on them for the most part are pretty cheap and seeing how this motor was used across all GMs car lines that had 6cyl at the time parts are easy to find and widely available which me cost is also cheaper than most other cars of those years
