@sojourner2013 I originally was worried about the 5.3. That is the reason why we went to the 6.2. Now everything that I'm seeing is related to the 6.2 being an issue lol. I guess you can't win them all
Yes, my Suburban has 5.3L with 226K miles and uses zero oil and has never had engine work done on it - very reliable and smooth. It's so sad GM uses AFM engines that can self destruct with a bad lifter and they don't even warn customers - it's what they put on the engine, so they build cars for gov. and not for CUSTOMERS?
Whoops, I errored, my mileage is 326K, but I could drive this cross country and it's still bullet-proof. I keep it up and have recently re painted it, so it's ready for the next 326K !!
@@SLP743I just sold my ‘23 Tahoe RST with 22k miles this weekend. So far I had taken it to the dealer for a loose lower control arm right after purchase, then a leaking evaporator (rust was found in the engine compartment) and then about six months later the drivers’ side a/c stopped working, was told a leak in the refrigerant line was found. Right after a 1500 miles roadtrip to North Carolina, I started hearing a ticking noise while idling by the passenger side. Was really concerned about the lifter issue coming up, not sure how it will fare with the next owner.
I see people have issues even with the delete. It's crazy. My 22 was something to do with a cam they said. This investigation is about bearings and there was also an issue wirh lifter bore. It's like this motor is destined to fail.
@ from what I understand a full AFM delete is a non-AFM cam, pushrods, and a tune (to delete the AFM). No OBD dongle. I have not heard of this going south, could be wrong and maybe I haven’t seen them.
@@170andahalffrom what I read, if you do the full delete like the commenter stated, they replace all the shitty parts with non DFM/AFM parts, aside from reflash. But this could be 3k-5k, so sinking that much into an already expensive car is insane. Just sold my 23 Tahoe RST.
If you're doing your oil change at 50% all the time. Just make sure to pre-fill those filters. Doing more frequent oil changes can lead to damage as each time you're going to start up dry. GM had an issue in 21-23 where new assembled engine weren't pre-lubed through the oil filter with an adapter. That causes pre mature wear of the main bearing. All in all, the main bearings and oil pressure are sensitive in these 6.2.
@Sonnycam24 smart move on the oil changes. Sludge will form if you go the recommend miles. Problem is these issues have nothing to do with lack of maintenance. They are just junk motors.
@twomontess do you notice any loud sounds at start up that go away after oil pressure buildup? That the only issue we have had on this new one. I just worry we will have problems in the future.
I have a 22 Yukon Denali with 53k, no issues or odd start up noises. A friend of mine just had his Sierra 6.2 stop while going 70 on the highway. GM replaced his engine under warranty. Please continue to communicate any updates you get. Wondering what my options are since I am well out of warranty. Sad because I’ve always loved this engine.
My sister bought a low mileage (about 25k miles on it) Camaro SS some years ago with the 6.2 V8 and she had nothing but all kinds of problems with the engine. She got rid of it and (surprising to me) she bought a brand new one. She's had this one for about 4 years and as far as I know, she's had no issues with it. The first one she had was a 2018 (I think) and the new one was a 2021 I believe.
I have a 2015 Silverado 6.2L I believe this was before all the issues. I did tune it to always run on 8 cylinders. I love my truck! 110k and running strong! Also average 17mpg on all 8 cylinders. 👍🏻 I’ve wanted to upgrade but with all the issues, I might just keep it.
My dad’s Silverado with the 6.2L just went spun main crank bearing, off warranty and will cost $20k CAD for a new crate engine with install! Earlier in its life had a couple bent rods around 75,000 kms
I have a 22 GMC 1500 4x4 Denali. 6.2 v8 . Runs great No issues so far . I change the oil every 3000 miles no matter what they say . Just turned over 16000 miles. So may God give you a good one.
Been running my 19 GMC Sierra Denali w/6.2 and 10-speed trans with auto 4x4 drivetrain. So far, it has 71k miles on the truck and the motor/truck has been rock solid, have had many long trips in this truck and it's always comfortable and has plenty of power to do what I need it to do. I have the Mighty Mouse catch can, S&B CAI, and a Corsa Sport cat back system installed. It's been a great running truck so far, I do run Amsoil in the motor and cases, trans fluid was fun to change out but still runs it and does very well. I have heard that the 6.2 had similar issues to the LT4 and LS7 which was an issue with the intake valve stems. I do plan on putting the Cadillac Escalade V supercharger, cam, heads, and exhaust on my 6.2 in the future since it's essentially the same engine.
@@170andahalf Yeah, having 600 to the wheels is a real game changer. I had 618rwhp in my 17 ZL1 Camaro before I traded it for my current truck. Would love to do the supercharger and other mods, just need the funding and time to do the upgrades.
so far my 2018 GMC Z71 Crew Cab SLT with the 6.2 has been perfect! I've taken it on 5,000 mile trips with no issues. I run Amsoil on all my fluids with the exception of the 8 speed only use what dealer calls for. I've had a catch can and the Range AFM delete. I also removed the thermostat on the transmission.
run amsoil also in the transmission. especially if you live somewhere cold. and if you are somehow mechanic change the torque converter asap or at least get it tune (not the engine the transmission).. you might save yourself a rebuilt a 120k km.. also delete the oil cooling lines thermostat and add a transmission cooler.. i might sound like too much but its the basic needed to get these last a lifetime.
You Chevy guys are quite dedicated and definitely have pockets full of money. The 6.2 has direct injection so have fun with carbon fouled valves in the intake later on, like if it makes it to 90 or 100k miles. It's a mystery to me why a 50's reworked over head valve engine like this sacred cow for Chevrolet keeps getting the following it does. My 2018 F150 with 130,000+ miles on it has port and direct injection and runs like a top. Changed oil around 10,000 until it got 100,000 miles , now change on or before 7,500. The technology that went into the 2011+ coyote 5.0 over head cam engine is second to none and now in it's 4th generation with 400hp stock @ since 2018 has 12:1 compression. So durable a person can throw a supercharger on or have Ford install one and get a full warranty and 700hp + depending on the supercharger. Can't even entertain the thought of owning a 5.3 or 6.2 that I would believe I needed to change oil every 3,500 miles, but hey that's what a person had to do 40+ years ago when even the oil wasn't that great and the engines had carburetors. Like I mentioned before anyone that buys a chevrolet has alot more money than I do or let's just say like's wasting their money way more than I do. GM loves your dedication and they have big pockets for all your money. Enjoy being broke and remember if you don't like you will learn to like it.
@@170andahalf No, entirely stock engine with the exception of fuel injectors. I did have an issue with the supercharger rattling at 50K miles. Cadillac replaced it for free as a recall was issued. exhaust system is all replaced, cat deletes, AR longtube headers with Corsa sport mufflers, aftermarket intake, pulley changed (forget the size) and HP tuner tune. Aside from that and a few mods to the intercooler system (to add strength) it is all stock. My only real issue is traction. I truly believe that there is a point with a street car where you either need to be happy with the HP or resign to driving the thing with drag slicks and I am not going to do that so< I am staying where it is at.
@@kl0wnkiller912 my 23 Zl1 1le was made into an exorcist by Hennessy....they had to replace the entire motor because mine had the bad bearings. Said it was only a matter of time before it blew. They said they were also seeing it in vettes and also Cadillacs. That's why they knew to check mine before just doing the normal upgeades
@@scottp7620 Interesting. well, so far I have not seen any serious problems. I don't thrash mine much though. A few burnouts here and there and maybe a couple of street races when someone gets uppity in a Mustang but otherwise I take care of it. From everything I have read and heard, bottom ends in LS engines are legendary. Of course you have to change oil regularly and monitor oil pressure. I did hear that some earlier LS engines had issue with the gear that drives the oil pumps stripping.
Does anyone notice the oil dip stick give 2 readings? Depends on the way it's put in the block. The crosshatch area is always higher than the back side, about 1/2 half a quart lower. It tricked me one day, the stick went in bowed out tords the wheel well, so it gave the low side of the reading, i hope this is correct? Try it and take a look at this crazy phenomenon. Look at it but turn the stick 180 degrees put it in, check oil, then turn it 180 and check again, witch one is correct?
Great to see you changing your oil regularly, I would guess most of the failures are down to poor engine oil changes, including contamination during sloppy oil changes?
@kellysmith7511 honestly I think most failures on a vehicle with under 100k boils down to failure by the manufacturer. There are many flaws with this design. Not one single issue keeps happening. It's a multitude of things.
I'm considering towing a motor home with a hitch on the 2001 Suburban with the 5.3; I'm not sure how towing would go and NEVER have towed much with it in the past. I'm - she's a small to mid-sized trailer for touring the USA for my wife - she hasn't seen the USA so much. The 5.3 isn't the best for towing, but it can do it.
@@170andahalf Friends that used to buy Suburbans every few years ARE NOW BUYING FORDS. They had too many maintenance issues - high costs and NO RELIABLILITY. I drive my vehicles in Mexico, so I stick with the OLD vehicles built when America built good cars. I do not want a guarantee car replacement - why replace junk with more junk?
It must be really cold where y’all stay at because none of my Cadillac Escalade Platinum sounds like that on start up and I got the 2008 body and the 2018 body both with the 6.2 and on my 2008 I have put over 200k highway miles on it and you can’t hear it running. It might be a Tahoe and Suburban thing with the engine sounding like that! The only issue I have had so far is I had to change my oil pump on my 2008 and my transmission coolant line on my 2018.

You are the second person who suggested the oil testing I will definitely be doing that on the next Oil Change
Chevy has had the loud start problems since the 90s. I had 2 camaros and 2 corvettes that had piston slap they called it, anyway nothing has changed with Gm over the past 25yrs except for making junk. Glad I switched to FORD. 😊FGM
As a GM.... now gm, I am a loyalist. I believe the failures are because of lack of leadership Mary Barra. Ive purchased 18 new gm 1/2 ton trucks and SUVs since 1989. Of all those and a lot of miles, I bet I had 4 warranty repairs, all minor, fuel pump , wheel bearing, water pump, the only outside of warranty repairs was current 2016 Sierra, trans temp sensor harness i fixed for $80 and an hour of my time. And 1 wheel bearing on this 145k miles , never keep this long , but It seems the quality keeps going down and the price goes up. Not to motovatied right now as i planned for a2025 AT4 Sierra 6.2 and a new Tahoe 3.0 oil burner.
@170andahalf yes sir when they replaced the engine the first time it only made it about 30kms. I ll be getting rid of it before power train warranty runs out that's for sure.
You can try a cold startup again but have the microphone near the engine. You could have some of the oil sent out for analysis if concerned. Also, check out the 'Motor Oil Geek' TH-cam channel with Lake Speed Jr. for some good content about motor oil.
@anthonynofi4871 I had 2 mics. One on me and one under near engine. I will for sure get the noise but I have to keep remembering to do it before my wife leaves in the morning. Lol
I do contract work so I have to travel to different states and I put 50 to 60k on my truck in a year and had no problems out of neither one of my Cadillac with the 6.2
Everyone wants to think afm is the only / main problem. its not. ALL of the engines in the class action suit are all built basically the same. i had this problem myself. i have a '16 ss that comes with the 6.2 lq9/ls3/ whatever other variants you want to list. costed me 12k to sort it out. issues have no happened again because i learned how to build the entire engine myself as my car sat for two years. The problems start with the rocker arms. you need to either replace or upgrade them. upgrade the trunnion needle bearings or get ones that already come with the upgrade applied. if you do this you can usually save the engine. i was also one of the first ppl to attempt to get on the class action lawsuit, but since my situation is unique i have to go after gm myself. theres no avoiding the lifter issues, even if u jump ship and go to the expensive 800 link bar lifters, WHICH MY CAR CAME WITH AND STILL BLEW UP. thats why the rocker arm fix is important. the lifter issue is pretty easily dealt with if nothing else causes a compound problem. once the needle bearings get ejected by the rocker arms, this is what STARTS the issues. if anyone wants proof of my 2 years struggle that i finally feel like i came out on top, and you can see pics of my car. -> drive.google.com/drive/folders/1KDksHMaGUfuf7BGgOc5xIOFIate0m_lM You can also find a copy of the original class action lawsuit and emails on that google drive. i just need to win the lotto for enough money to sue gm at this point. they better hope pump doesnt give me 3.2mil or im coming full speed.
@@MAD_BST yep. My 22 had an issue with the cam. Not sure exactly what it ended up being because they bought the vehicle back so it didn't have to do much research. It seems like problems are all over the board. From main bearings to rod bearings to lifters
My 2018 Escalade with 100000 miles had a engine failure because of lifters going bad wiping out the cam and trashing the engine. It cost me a small fortune for a new rebuilt long block. I’m told that this is a common problem because of the variable cylinder function. Not very happy with GM!
Had a 2021 AT4. At 15k miles first motor took a shit. Broken lifters. Took 4 months to get a new motor 😊in and the truck back. Called GM and got a person with a kid screaming in the background that was rude and had no concerns for my problem. No reimbursement or credit towards paying for a new truck while it sat on the dealer lot broken. Got truck back and it wasn’t even 5k miles later that the motor shit out again at 20k miles. Get out of the trucks with 5.3, 6.0 & 6.2 engines that have AFM/DFM……. This is a stupid problem that is going to bury what once was a great company. My old 1999 1500 had 100k miles with no issues at trade in for a 2004 2500 that had over 105k miles when I traded it…. The good old days when stuff was built to last…..
Can ANY of the automotive makers produce anything without issues in this day and time. You can only take out so much in the name of profit before it starts to compromise the quality of their products.
@@170andahalf - I like to say iPhones on 4-wheels. My point is, focus back on the quality, durability and longevity of the product. That's the motors, tranny's and suspension....aka- mechanical.
GM guy here, unfortunately these newer engines are not going to last with AFM . It seems like the quality took a nosedive after 2015 or so. Or it could be as someone mentioned in the comments that GM is rushing thru all these designs since they are pressured from the government to maintain a certain fuel efficiency. I have a 2007 GMC Denali with the original 6.2 @ 256K , Non AFM from factory. The Transmission just failed at 254K. Took it out myself and sent it to get rebuilt and reinstalled. Still going strong .
@josevaldes846 i am in need of a vehicle. Planning something this spring. With the price of even a decent used i can build something so much better. I'm still not sure if I'm going with a truck or a Tahoe type vehicle. I want to just throw a 5.3 or 6.2 with a turbo to make something fun. Simple cam change and tuning will give me 500 or so.
@@170andahalf You will definitely build something fun and reliable with either engine. I had a 2004 Tahoe Z71 / 5.3, ton of power stock and reliable as hell and a 2004 Silverado 2500 HD Turbo Diesel which pulled like a freight train, weak link is their independent suspension out front when using a plow. Unfortunately I Had to get rid of them when the economy took a nosedive from the last recession . The Denali we now have is used for work/ long trips with the family however I would like to purchase the same pickup in the future . Same year or max 2007-2008. The new ones require all that DEF crap, besides I can’t afford NEW even if they were reliable. Best of luck with your build 👍

89,000 engine locked up no warning, out of warranty gm was no help cost me 12,000 out of pocket. Took 4 months to find an engine. Had to go to a 3rd party. I will never own a gm product again after dealing with corporate they are a joke.
@@laveaux8915 12,000 for an engine just seems astronomically stupid. I almost feel like you could buy an aftermarket crate motor that would be a much better option for that price.
The cost of maintenance is too high today, so young people cannot afford to maintain their cars. Mechanics want $130/hr.; however, my solution is to take the vehicle to Mexico for Master Mechanics can rebuild the vehicle. One mechanic did $5,000 worth of work for only $1,100 - did an amazing job replacing parts that wear like rank'n'pinion, wheel bearings, suspension, etc. Then, a blacked-out driver in a Suburban hit the grill and fender, so $12K to repair that here - did it in Mexico for 2K$ - did an amazing job, because I have friends in Mexico. Painted my "01 Suburban for $1.2K that involved a lot of prep work due to sun damage.
I have been wrenching on motor vehicles since I was 15 years old. I am now 64 yoa and cannot understand why GM is becoming worse then Chrysler Jeep Dodge? Furthermore I cannot understand why anyone is spending their hard earned money on GM with the 5.3 or 6.2 engines? In the area I live in I currently know of 6 GM trucks with these engines. And all have failed? They are all under warranty and being bought back by GM or having engines replaced? Why? Also why would you agree to buy another GM with the same engine? They all are ticking bombs? Just like Toyota engines in the Tundras?
@abw121 thisbisbso crazy. I started researching in 21 and all the issues were with the 5.3. That's why I chose the 6.2. We wouldn't go wrong with the above purchase buy back. They are still an easy resell. I personally want a Ford lightning. Lol
Never had a problem with the two I’ve had. We’re talking >2% failure rate? Honestly, my friend from high school is a service manager at GM and he said they rarely see failures. I’m not a fanboy as I have a 3.0 duramax now.
Absolutely love the diesel. Averaging 24.3 mpg in mixed use. Can get high 20’s on the interstate which is amazing for a full size SUV. After 26,000 miles no problems to report. Since I always ran premium in the 6.2, I find no cost difference running diesel.
Every single person I've known with a 6.2 of any generation has blown the engine up. Mine had cam failure the others seized etc. total junk there is definitely an inherent problem
I have a 6.2 in my 2017 Z71. Lifter failure at 34K. Complete engine destruction. Warranty rebuilt it. Its ok now, but it burns 1 quart of oil. Every 1000 miles.
I don't think anyone has any idea what the issue may be, if there is one. I think people have a tendency to over react. I'm not on GM's side, but until someone uncovers a legitimate defect, I'm going to believe it's an owner issue. If it was a design/component issue, you would see a lot more failures. The investigation will probably reveal nothing, as usual.
But an owner issie wouldn't happen at 11k miles with 2 oil changes already done. They then did a buyback. Are they doing that to not have to report it?
@@170andahalf Without knowing all of the details, it would be hard to say. I think they had no choice regarding the buyback. Kudos to the dealer for doing the right thing.
I made it 26,000 before catastrophic failure. GM told me it would be 8+ months before they could get a new engine. There were no indicators it was going to fail. I got rid of it. Never again GM. Not my first negative encounter with GM.
@170andahalf I have the 2.7 4 cylinder. I wanted to get the 8 cylinder 5.3 or 6.2 would have been good. But they were really pushing the four cylinders.
Soooooooooo sold your Chevy (under lemon law) to buy another Chevy with the exact same motor............are you serious you CANNOT be this dumb? You cannot fix stupid!
Stupid would be buying a brand new vehicle. 🤣🤣🤣🤣. Yep, that would be me. The 6.2 had a great track record when I started my research in 22. The fabricated virus caused an incredible increase in price for new vehicles around that time, so it was cheaper to buy new. When researching lemon law gm agreed to buy back so they didn't have to go through the lemon law approach. They paid me more than I paid for the vehicle to buy it back. No depreciation for the miles. It was a no brainer. It was a free 12000 mile rental. We just had to buy another gm vehicle. I figured if they took care of us the first time, then why not buy it again. The only way I am out money is if I let it go out of warranty and then the motor blows. We will sell it off before that. My main complaint is just why does this keep happening. When you spend this much on a vehicle, it shouldn't have issues.
@@170andahalf Next time buy a gen 2 Tundra with the holy grail 5.7 it will last you for ever! The new ones are junk BUT the ones pre 2022 are great! I just bought a 2020 Toyota Tundra with the 5.7 and it will "probably" out last me!!

I'm gonna give GM a partial pass on this because the government forces them to do crazy things to perfectly solid engines to eek out 1.5 mpg highway under perfect conditions and if they don't do it they will be fined crazy amounts of money by the government. What that amount is I've never been able to find ( it should be on the windows sticker ).. It's got to be a huge fine if the company goes through the hell of designing and implementing these cylinder deactivation systems and all the reputational damage and service costs that come with it,, and they keep doing it.. I challenge anyone to find out what that number is...
@ These EPA folks are zealots and their goal is to KILL all non EV's... That's what the new 2027 CAFE and pollution standards are designed to do,, hopefully it'll be stopped..
top tier fuel?????? if not are you treating fuel per owners manual????? carbon buildup on pistons will cause cold engine noises also you will hear more high pressure fuel pump noise at cold start up/IT NEEDS MORE FUEL WHEN COLD!!!!!!
its up to you to use proper fuel or buy fuel treatment if not using proper fuel so cant really blame anyone for your vehicles being tied up in service department seen this time and time again
@mattmattson9317 one of the questions that came up when the original 6.2 blew up was did we have the proper oil and we're using premium fuel. My guess they have a way to test ir because the service manager said it was all good.
GM's quality control is not what it once was, and in my opinion the corporation is prone to lie since the government has taken over GM, and the engineering is absolutely not as good as it once was either! You have all of these college educated engineers that think that technology will solve everything and it just seems to create many more problems than they fix. They could take a lesson from Michael Kalashnikov and engineering simple instead of complicated is always better!
@850Reed yes. So far resale. Lol. Seems to be a great motor from what I see but every cheap suburban i see always ends up being the diesel. Not everyone is a fan so that hurts value.

If you're doing your oil change at 50% all the time. Just make sure to pre-fill those filters. Doing more frequent oil changes can lead to damage as each time you're going to start up dry.

My sister bought a low mileage (about 25k miles on it) Camaro SS some years ago with the 6.2 V8 and she had nothing but all kinds of problems with the engine. She got rid of it and (surprising to me) she bought a brand new one. She's had this one for about 4 years and as far as I know, she's had no issues with it. The first one she had was a 2018 (I think) and the new one was a 2021 I believe.

Been running my 19 GMC Sierra Denali w/6.2 and 10-speed trans with auto 4x4 drivetrain. So far, it has 71k miles on the truck and the motor/truck has been rock solid, have had many long trips in this truck and it's always comfortable and has plenty of power to do what I need it to do. I have the Mighty Mouse catch can, S&B CAI, and a Corsa Sport cat back system installed. It's been a great running truck so far, I do run Amsoil in the motor and cases, trans fluid was fun to change out but still runs it and does very well. I have heard that the 6.2 had similar issues to the LT4 and LS7 which was an issue with the intake valve stems.

run amsoil also in the transmission. especially if you live somewhere cold. and if you are somehow mechanic change the torque converter asap or at least get it tune (not the engine the transmission).. you might save yourself a rebuilt a 120k km.. also delete the oil cooling lines thermostat and add a transmission cooler.. i might sound like too much but its the basic needed to get these last a lifetime.

You Chevy guys are quite dedicated and definitely have pockets full of money. The 6.2 has direct injection so have fun with carbon fouled valves in the intake later on, like if it makes it to 90 or 100k miles. It's a mystery to me why a 50's reworked over head valve engine like this sacred cow for Chevrolet keeps getting the following it does. My 2018 F150 with 130,000+ miles on it has port and direct injection and runs like a top. Changed oil around 10,000 until it got 100,000 miles , now change on or before 7,500. The technology that went into the 2011+ coyote 5.0 over head cam engine is second to none and now in it's 4th generation with 400hp stock @ since 2018 has 12:1 compression. So durable a person can throw a supercharger on or have Ford install one and get a full warranty and 700hp + depending on the supercharger. Can't even entertain the thought of owning a 5.3 or 6.2 that I would believe I needed to change oil every 3,500 miles, but hey that's what a person had to do 40+ years ago when even the oil wasn't that great and the engines had carburetors. Like I mentioned before anyone that buys a chevrolet has alot more money than I do or let's just say like's wasting their money way more than I do. GM loves your dedication and they have big pockets for all your money. Enjoy being broke and remember if you don't like you will learn to like it.

The problems start with the rocker arms. you need to either replace or upgrade them. upgrade the trunnion needle bearings or get ones that already come with the upgrade applied. if you do this you can usually save the engine. i was also one of the first ppl to attempt to get on the class action lawsuit, but since my situation is unique i have to go after gm myself. theres no avoiding the lifter issues, even if u jump ship and go to the expensive 800 link bar lifters, WHICH MY CAR CAME WITH AND STILL BLEW UP. thats why the rocker arm fix is important. the lifter issue is pretty easily dealt with if nothing else causes a compound problem. once the needle bearings get ejected by the rocker arms, this is what STARTS the issues. if anyone wants proof of my 2 years struggle that i finally feel like i came out on top, and you can see pics of my car. -> drive.google.com/drive/folders/1KDksHMaGUfuf7BGgOc5xIOFIate0m_lM

@justjoe469 sounds like they have problems all around.
i'M JUST SICK!..What, do i have to go buy a mopar now!
@Jeffbob442 oh my.... let's not get crazy. Lol. I mean who buys a Mopar? I would rather pay for a new motor. 🤣🤣🤣
Way to go GM. Making the bad worse.
@@jeffreygoss8109 it's sad. Speed this kind of money and roll the dice
@ rolling the dice at least gives you a chance. 😂 I hope it works out for you….this time.
@@jeffreygoss8109 Or it doesn't really quick so we don't have to wait until after warranty runs out. LOL
Soooooooooo sold your Chevy (under lemon law) to buy another Chevy with the exact same motor............are you serious you CANNOT be this dumb? You cannot fix stupid!
Stupid would be buying a brand new vehicle. 🤣🤣🤣🤣. Yep, that would be me. The 6.2 had a great track record when I started my research in 22. The fabricated virus caused an incredible increase in price for new vehicles around that time, so it was cheaper to buy new. When researching lemon law gm agreed to buy back so they didn't have to go through the lemon law approach. They paid me more than I paid for the vehicle to buy it back. No depreciation for the miles. It was a no brainer. It was a free 12000 mile rental. We just had to buy another gm vehicle. I figured if they took care of us the first time, then why not buy it again. The only way I am out money is if I let it go out of warranty and then the motor blows. We will sell it off before that. My main complaint is just why does this keep happening. When you spend this much on a vehicle, it shouldn't have issues.
@@170andahalf Next time buy a gen 2 Tundra with the holy grail 5.7 it will last you for ever! The new ones are junk BUT the ones pre 2022 are great! I just bought a 2020 Toyota Tundra with the 5.7 and it will "probably" out last me!!
@Tobstertacoma dear god even the tacomas have gone to crap? That sucks.
@@170andahalf LOL, YUP they sure have! Everything that Toyota has made with a turbo on it is now junk. I am NOT a turbo fan myself.
@Tobstertacoma i am 100% a turbo fan. Just not on a daily driver. I want to build up an LS turbo to throw in something. I just love the sound of the pop off. Lol
Why aren't any of these corporate bigs going to jail for Purposely building faulty engine parts. Those parts were planned to fail after warranty.
@@douglastaylor8039 yep. The cost during warranty to them pales in comparison to what they make after
2015 Yukon Denali 6.2 all kinds of problems. I made videos on all of them.

@@dannyjohnsonsgarage just seeing the motor completely apart is enough to think you had some issues. Lol
Its all so avoidable GM needs to get rid of the cylinder deactivation which is the main culprit.....
@AndrewJacobson-cq2om absolutely correct.
The direct result of an Affirmative Action leadership model !
@@JohnBerry-z7o interesting take. Never researched the topic at gm.
6.2 engine or the 5.3 is not good for a truck I have a 2021 silverorb with 70.000 on my pick up truck 2500 HD with a 6.6 engine the engine is doing very good all the time
@@johnthompson4863 I will have to look into that
I'm gonna give GM a partial pass on this because the government forces them to do crazy things to perfectly solid engines to eek out 1.5 mpg highway under perfect conditions and if they don't do it they will be fined crazy amounts of money by the government.
What that amount is I've never been able to find ( it should be on the windows sticker )..
It's got to be a huge fine if the company goes through the hell of designing and implementing these cylinder deactivation systems and all the reputational damage and service costs that come with it,, and they keep doing it..
I challenge anyone to find out what that number is...
To keep under the gas guzzler rule or something else?
Exactly. The government imposes standards that cause big problems.
@ These EPA folks are zealots and their goal is to KILL all non EV's...
That's what the new 2027 CAFE and pollution standards are designed to do,, hopefully it'll be stopped..
@@yougotmossed3592 i can't currently name many things the government doesn't mess up. Lol
Same situation with the new Toyota engine disaster. Wouldn’t buy a new Tundra anymore. Too much complexity added to an engine to save fake mpg.
I solved my GM problems, never buy another one!
That's funny 🤣🤣🤣
Sounds like a dump truck with 400,000 miles on it.
@@douglasldn2831 lol
They say that's normal.
You need to rid yourself of that soon to grenade motor asap! WAY too much money for a motor that you have to worry about every day!!!
@rj-me3fh yep. Will for sure be gone before warranty is out but what company has a good motor?
As of GM hasn't been building engines for over a hundred years, what the h*** GM?
@@donp.8172 exactly
top tier fuel?????? if not are you treating fuel per owners manual????? carbon buildup on pistons will cause cold engine noises also you will hear more high pressure fuel pump noise at cold start up/IT NEEDS MORE FUEL WHEN COLD!!!!!!
@@mattmattson9317 100% premium. They actually checked it when it blew
@@mattmattson9317 and it's 60 in the garage.
@@170andahalf CHECKED WHAT?
its up to you to use proper fuel or buy fuel treatment if not using proper fuel so cant really blame anyone for your vehicles being tied up in service department seen this time and time again
@mattmattson9317 one of the questions that came up when the original 6.2 blew up was did we have the proper oil and we're using premium fuel. My guess they have a way to test ir because the service manager said it was all good.
Free oil change with every engine swap.
@@matthunter7888 lol. Exactly. Seems like a marketing ploy.
GM's quality control is not what it once was, and in my opinion the corporation is prone to lie since the government has taken over GM, and the engineering is absolutely not as good as it once was either!
You have all of these college educated engineers that think that technology will solve everything and it just seems to create many more problems than they fix.
They could take a lesson from Michael Kalashnikov and engineering simple instead of complicated is always better!
@@kimdearrington258 totally agree.
Does their diesel motor have any issues?
@850Reed yes. So far resale. Lol. Seems to be a great motor from what I see but every cheap suburban i see always ends up being the diesel. Not everyone is a fan so that hurts value.
not all premium fuel is top tier!!!! and 60 degrees is cold! anything under 210 degrees is cold
Ok
That engine didn´t sound too good.
Good luck finding any new vehicle that is reliable. Thay don´t make them like they did before the Greenies with their CAFE RULES came in.
I can't disagree with either of those statements. LOL. The thought for my next vehicle is to build off an older vehicle.
@@170andahalf An older Toyota or Honda would be the best with a new or rebuilt motor. These DIE plastic engins are nothing but trouble. Trump wants to bring the auto industry back....to do that America has to make reliable cars like they use to.

@LorenBosma just crazy
Toyota, now GM. Keep your oldies folks. Learn to diy
@@TexasVexes for sure. That's my plan
Sell it!!!!! GM totally screwed up on this engine. The EPA emission and mpg requirements have ruined any hope of long lasting car and truck engines. The designs are flawed and the owners are stuck with absolute junk.
@AS-tt8ui if I knew they would replace the engine it wouldn't bother me. What scares me is them repairing something and then it goes out of warranty and blows
It's really sad toyota tundra engines are junk to bearing failures you would think they would get better not worse
