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.

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.

Thank you! I keep my heavy purse in the passengers seat and the check airbag light stays on... Is this serious and how much would it cost to fix?

Thank you.

Thanx it was very interesting!!!!😅😅😅

Buenas tardes veo que tiene vastante ecperiencia en este tipo de vehiculo, mi cadillac cts 2004 dejo de marcar temperatura gasolina over driver y llantas de derrapr ya le han buscado por todos lados pero no le encuentran el motivo, la señal si llega a la computadora

Was the last year v6 anything better the rest of the previous years?

Do you have a video on how to replace a gear on a 2006 STS Drive a seat it won’t go forward to backwards

What kind of rear ends do the V8 cars have?

I’m thinking about buying a 2008 sts v6 with 109,000 miles on it, should i? There’s no check engine light and it seems pretty well maintained

I got the STS V8 I'm dealing with trying to get it through the emissions here in Illinois

What about door handles peeling or the v6 timing chain failures?

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?

Does the 2009 Cadillac STS V6 have a Northstar?

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.

What are your guy’s thoughts on the LH2 North Star V8?

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.

2005 Cadillac STS won’t start when I press the button, makes a computer noise and all lights and dash come on, will not turn over at all though

Oil pressure sensor was a big issue for me and ultimately led to selling the car after 5 years. Oil leaks are bad on north star engines

It would be nice if you said how much it costs to fix these problems

Ayo I have a Cadillac STS 2006 and my car struggles to start & sometimes when I’m driving the gas pedal will stop working anybody kno what it could be

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.

I had v8 rwd and I would always get water in my headlights. Pissed me off

do one on the v8

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.

2006 revs up when started but a few seconds later goes back to normal

My car blows hot on left of steering wheel but everything else cold and both panels would be set to 90 and be blowing cold 2005 STS

I got the same engine in my 2007 srx

I have a 2009 STS and the biggest issue I have is the air-conditioning and I'm only getting warm air on the right and barely cold air on the left.

WHAT ABOUT THE HIGH FREQUENCY OF TIMING CHAIN FAILURE ON THE 3.6 LITRE V6?????!!!!!

Damm, I keep my laptop and bag on that seat all the time. I have a check airbag light but it always goes away when I go to get the reading for it.

My 2005 is leaking oil bad... Any help

The first gen goes until 2007. The 2008 was updated.

Anyone ever have an issue with the rear ashtray making crazy hissing noises??

Let’s do the 8th gen civic please please PLEaSE!!!!

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.

I’m thinking of buying a 06 sts4 with the northstar. Any sts4 northstar owners out there at can tell me if’s it’s worth buying

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!

Wow no major issues?

The 3.6 is a trash engine. Go with the V8 if you're in the market.

236,000 on the odometer first problem oil sensor and of course I did the cams shaft sensor 5 years ago that's it

Plus, STS stands for Seville Touring Sedan. There haev been plenty of Seville models.

Those aren't the 5 problems of a STS

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.

There's only one generation anyway.

Don't buy 3.6 Engine only the V8

The 3.6 engine is enough for me to avoid this car. Period

ZTHIS IS NOT THE FIRST GENERATION STS!!!!! THE FIRST GENERATION WAS INTRODUCED IN 1992!!!!!

I also thought the STS was FWD.

Cadillac makes the worst engines ever lolol
