2005 V8 STS bought used. Required new keyfobs when we bought it used. I've had the Remote Antennae and Remote PCB replaced, Driver Side Door Handle Switches and Antennae replaced. The Air Bag plug under the Driver's Seat needs to be reseated every once in a while to clear the air bag warning light. Cam Shaft position errors required reseating the connectors on top of the valves. Hood open switch is jumpered out to keep the error from going off. Front Emblem fell apart and needed to be replaced which gave radar and cruise disabled warnings. Headlights filled with water. When you can see water in the headlight there is about 1 pint of water in the housing. Driving lights were out, driver side mounting tab broke when replacing the bulb. Made a 3D printed flange with a tab and epoxied that in place so that I could reinstall LED bulbs. Last Summer my AC Door Actuators were ticking. This winter we had no heat on the driver's side so we're looking at replacing or modifying the Driver's side AC Door Actuator. Ran through the winter with heat on high and recirculation on. Front passenger door handle will not reliably open the door. Suspect that the switches are bad and working on them now. Plastic trim on the trunk lid to pull the trunk lid down has fallen off and will not stay put. Driver seat side plastic fascia tabs were broken and we replaced that piece. We've replaced brake lines, rack and pinion twice, transmission cooler lines, and will need to do the gas lines soon. Car is 17 years old with 110,000 miles. Rear quarter panels are starting to bubble on both sides where they mate with the rear bumper cover. We had a slow coolent leak since we purchased the car. Last Spring the leak was bad enough to figure out where it was leaking. Mechanic claimed that the repair would cost require a new motor so he added a leak stopping agent which has sealed it up and we no longer need to top off coolant every six weeks. We have a rear seal going bad and the "fix" is to replace the rear axle, so again we are living with it and will have the rear pumpkin checked and topped off at each oil change. One TPS sensor failed and was replaced. Other than brakes, oil changes, and tires that all that has gone wrong on our STS. Other than the radar cruise control and warning bells I still like the car.
You are a blessing. Helped me identify why my 2010 cadillac sts has been saying service stability system. check engine light flashing as well.. sure is abour time i change that steering wheel position sensor.
if you like the car then maybe, i bought my 06 sts for a deal after previous owner hit a deer.. i bought it thinking hell yeah i can have a caddilac for cheap, my car needs a new front end and just the headlights are 400 bucks to replace not counting the hood and both fenders and the front bumper. other than the hood and fenders being smashed and headlights being smashed my car run and drives as is.
Yep,my 2008 has crome plastic peeling off and the the seat plastic bezel ( control nobs ) snap off plus the back of the seat plastic snaps off, it's only got 58,000 miles on it. It's sad that GM let their cream de la cream go to down like that. They should last a LONG time. It's all for profit 📈.

This is the v6 I was hoping it was the awd v8 that’s what I have. So far it’s needed a new steering rack and intake manifold gaskets, I also need to replace my valve cover gaskets.
I have the 2005 STS AWD Luxury Sports Sedan 4.6 Ltr. NorthStar V8 VVT 5 Speed Automatic Transmission w/Driver Shift Control Catalyst Feedback Fuel System. I Have 165,000 miles and I'm getting into some drivability issues. I've learned that the First Generation OEM, White Top ignition coils are almost impossible to find. There are (2) upstream O2 sensors that are called air/fuel sensors and there are (2) downstream that all have different wiring connectors (oval, square or rectangle). It depends upon when your vehicle was built within the year. I had to replace the water pump 1 1/2 ago. The MAF Sensor seems to go every 1 1/2. I'm about to replace the MAF and the MAP Sensors. I just replaced the plugs and the throttle body, last week. Also, the battery seems to swell and malfunction about every (2) years and I have been using the Gold Series. How is yours?
Gas caps can be the culprit of problems in many cars. My mums Camry was throwing errors and it was just the gas cap. As for Cadillacs, I think they should build them as they used to, really big and really powerful but smooth (i.e. lotsa effortless torque) and as comfortable as a couch. My last Caddy was a big ole 1996 (I think) Deville. The whole a/c plastic box that attached to the firewall was literally falling off so I traded it for a Honda Civic, I believe. lol Nice Videos.
@@johntipton1874 northstars are fine engines, every design has its issues. But any 3.6 across any platforms are garbage overall numbers prove it. Ratio to total engine failures are very high its always a crap shoot with any car. But thats what makes car choice great its all about preference and taste. And a little bit of luck that Bob at the factory had a good day building your car. Lol
Multiple major issues you didn't mention. The 3.6 engine is prone to engine sludge, oil consumption, timing chain failures and undersized pcv orifice holes. All of those are critical factory defects that will cost serious money during ownership. I'll never own another gm especially the 3.6 engine.
Yup, the timing chains on the 3.6 are basically a ticking time bomb, so much so that Cadillac had a recall on them. I got brand new ones put into mine back in 2015 for free.
My 05 3.6 has 165k on it, oil is SOLID black in less than 100 miles after oil change, uses oil like crazy. Starting to foul the plugs now. Also so many electrical issues. Doors, windows, HVAC. All work ONLY when they want to.
the door front door handle issue. Sucks. Currently both of mine will not open. Can open drivers door with key only. Pass door can only be opened from inside.
Hey guys, I’m having a misfire on cylinder 1. I have replaced ignition coil, fuel injector, and spark plug. Still misfires. I then noticed a broken connector on one of the camshaft sensors. Do you think that could be cause the misfire?

@@taqrimbadrut572 Blend door actuator. I have the same issue and I just go under the dash and wire it into place during the summer. Then remove the wire for the winter. There's a vid on youtube.
Temperature actuators are common to fail on these. I bet you can hear them tapping in the dash also. The dash has to come apart to do it. I would install all new actuators so you don’t have to pay the labor to do another one in the future.
Most likely it’s just low on juice. Never would have believed it myself, but I’ve seen it on MANY GM cars with split-systems. 1/2 a can fix’s most of them.
Just a FYI dont buy any version of these cars unless the have low mileage and no cel. This is the early ages of the 3.6 which has gotten better since then but still has some of the same problems. The Northstar v8 is one of the worst V8s GM ever made. I dont understand why they did not put the reliable 3.8 v6 or the 5.3 v8 in it until they tested the 3.6 more. Many things outside the engine will fail also. But if you still want one then just make sure nothing is currently failing with the engine and take good care of it. There good looking cars but they were the test cars for what Cadillac has become today.
Worst car I ever bought. I am a home mechanic and have fixed almost everything. All 4 pillars leaked, trunk would fill with water and trunk release wouldn’t work on the door or remote bad cats All the plastic on all 4 doors are broken, 2doors don’t open from the outside, motor mounts transmission mount abs sensor hubs and rotors, flex disc and carrier bearing, rear differential bushing and front seat doesn’t adjust. Great looking and I got it very cheap. The previous owners were at a loss with the repairs adding up. If I had to pay someone I wouldn’t have purchased it. Lots of factory failures. I understand wear and tear but I have much older cars that didn’t have this many problems. That thumping you hear under the car is the carrier bearing and rear differential bushing just fyi.
Nope! You’ve got this all wrong. I’ve been working for Cadillac for 18 years. Master certified. None of these are common problems. I drive a 2011 daily. Great car. Only common issue you have on the early models is timing chains stretch and will need to be replaced. Maybe a purge valve too.
2007 s ts p0008 and p0017 just got p0008 code light was on and off now stays on was told change vvt selenoid or cam sensor where should I start or is it chain runs ok loss of power and gas mileage sucks rough idle also
John I just bought a 2011 CTSL 3.0 with 106,000 in excellent condition. What is your opinion on when I should get the timing chain replaced? Thanks, Al
I had Civic 8th generation in hatchback 1.8 gasoline. The car is too heavy so IT burns a lot of fuel, constant problem with breaking pads. I have no idea why but I had to change front left light bulb very often. From the other side nice acceleration very comfortable. Back seats are folding in many ways so you can put some stuff at the back if its needed. Besides mentioned breaking pads any other mechanical issues.
Yes and no. Cadillac previously used the Seville moniker for decades with various sub-models or named option packages (brougham, d'elegance and so on), then began adding sub-model designations such as STS, SLS, ETC, DTC, and so on. Eventually they dropped the old names completely and went with the 3 letter models across the board with the only exception being the Escalade. So in 2005 the STS designation was the model and not an option package, thus making it the first generation for that model.
Terrible, I own the 2008 STS its even red like that with the V6 and RWD, ive literally never had any of those problems. But i do take care of it, infact if you slammed my door like that your fingers would be in it the next time!
After 2005 regular maintenance will give a reliable car even the North Star because GM updated the head bolts from the 90s North Stars to heavy duty head bolts found in the high output engine from the Corvette
