Common Cadillac Sts problems
The Cadillac STS, a luxury sedan produced from 2005 to 2011, has several common problems that owners have reported. Here are some of the most frequent issues and their details:
- Camshaft Actuator Solenoid Valve Failure: This problem can cause a check engine light and drivability issues due to improper timing of the cams. The camshaft actuator solenoid valves control the flow of oil pressure to the VVT actuators. To prevent this issue, maintain the oil at the proper level and change the oil regularly.
- MAP Sensor Failure: The Manifold Absolute Pressure (MAP) sensor measures the pressure inside the intake. A faulty MAP sensor can cause drivability issues and a check engine light with a MAP sensor code. To fix this issue, locate the MAP sensor, disconnect the electric connector, remove the bolt, and replace the sensor.
- Passenger Presence Sensor Failure: This problem can cause the air bag light to be on with a code for the passenger presence system. The passenger presence sensor is located in the passenger seat and senses if there is a passenger on the seat for the air bag system. To fix this issue, replace the sensor.
- Steering Wheel Position Sensor Failure: This problem can cause the service stability light to be on on the dash and the ABS light to be on. The steering wheel position sensor is located at the base of the steering column and senses the steering wheel's position. To fix this issue, replace the steering wheel position sensor by following specific steps, including disabling the air bag system, removing the lower dash panels, removing the intermediate shaft, and sliding the sensor out.
These are some of the most common problems reported by Cadillac STS owners. Regular maintenance and inspections can help prevent some of these issues.

Cadillac Sts 2008
- Date Of Incident: 2021-11-25
- Date Complaint: 2021-12-13
- VIN: 1G6DK67V180
- Components: ENGINE
- Summary: The Cadillac Company sent me a letter several years ago informing me of a premature timing chain wear and the illumination of the Service Engine light. They knew about this defective engine problem but they did not recall the vehicle. Instead they extended the engine warranty to 10 years or 120,000 miles. I have only 90,000 miles on my vehicle but I've owned it for over 10 years and now the check engine light is illuminated. The Cadillac dealer refuses to extend the warranty. This is a safety issue because if the engine were to fail the driver would also lose power steering and power brakes putting the safety of the vehicle occupants and others at risk. I believe that this vehicle and other GM vehicles with the 3.6 liter engine should be recalled and repaired at no cost to the vehicle owner.

- Summary: I UNDERSTAND THAT 2006 CADILLAC CTS HAS A RECALL FOR AIRBAG PROBLEMS. CADILLAC DOESN'T DENY THAT THE SAME SYSTEM WAS USED IN THE STS. I'VE SEEN SEVERAL COMPLAINTS ABOUT THE SAME PROBLEM. I JUST WONDER WHY THE STS WAS NOT RECALLED. I KNEW THERE WAS NO WARRANTY, AND THAT'S WHY I CONTACTED CADILLAC. KNOWING THIS THEY SENT ME FOR A DIAGNOSTIC, WHICH WAS A WASTE OF TIME AND MONEY. THE END RESULT WAS THAT THEY SAID IT'S NOT UNDER WARRANTY. I WOULD JUST LIKE YOU TO INVESTIGATE TO SEE IF THERE SHOULD BE A RECALL. THIS IS A SAFETY ISSUE THAT CADILLAC SHOULD ADDRESS. *JS

Vehicle year: 2009
The 302-horsepower engine with direct injection V6 is a great feature. The bolder look on the outside and inside is sure to attract younger buyers. As someone who is 41 and in need of a 4 wheel drive car that can accommodate 3 car seats in the back, I looked at several options including the BMW 535xi, Lexus GS350 AWD, Infiniti M35 (currently drive Infiniti M45), and Audi A6. However, for the money, I stress that the 2008 STS was the best value. I particularly appreciate the increased performance and the side air extractors incorporated into the front fenders of the STS. Additionally, the new chrome-plated door handles and lower rocker moldings add more presence and refinement to the car.

Hey there! I noticed that you own both a 2004 BMW M3 and a 2000 BMW M5. It's a shame to hear that the M5 had some reliability issues and spent more time in the shop than on the road. I can definitely understand why you decided to try an American car and bought a Cadillac STS. While the handling may not be as tight as the BMW, the ride and technology in the STS are superior. I'm glad to hear that the STS holds its own in performance!

Congratulations on your first Cadillac! It sounds like you made a great choice. I appreciate your attention to value and performance when selecting your car. The 302hp 3.6L DI V6 engine and 52/48 weight distribution with AWD make for an impressive ride. I'm glad to hear that the STS handles well and is comfortable, especially compared to other luxury cars like the Lincoln MKZ, Cadillac CTS and SRX, and Lexus ES 350. It seems like the STS strikes the perfect balance between luxury and performance for your budget. Thank you for sharing your experience with us!

Vehicle year: 2008
I noticed that you had driven a Volvo S-60 with AWD and were looking for a bigger AWD car. After considering BMW, Audi, and Lexus, you ultimately settled on the STS with the new direct injected V-6. It sounds like you made a great choice! The car has every bell and whistle, including remote start, heated-cooled seats, and a heated steering wheel. Not only is it good looking on the outside, but it's also very attractive on the inside. It's a great highway cruiser, but also very agile and responsive in city driving. And in snow or rain, the AWD is superb! Thank you for sharing your experience with me.

Vehicle year: 2007
I have to admit that I don't use it very often, as it's more of a weekend car. Additionally, due to the summer tires, I tend to avoid driving it when it snows. I purchased it used in 2008 with only 7k miles on it, and over the course of 8 years, I've put slightly over 60k miles on it. Apart from regular maintenance such as oil changes, brakes, and tires, I've only had to replace the battery due to its age. I did have an issue with a pothole that caused damage to a rim and a lower control arm, but both were replaced. Unfortunately, the glove box latch broke, but I'm now extra careful with it. While it may not be high-tech, it does have GPS and a remote garage opener, and the stock sound system is excellent. Although it could benefit from a USB and WIFI, it's a car, not an internet router. I'm hoping to get at least another 10 years out of it, if I'm lucky enough to live that long. I did have some issues with the GM dealer support in my area, as they were unable to fix anything correctly, and even struggled to air up the tires properly.
Are you having problems with your Cadillac Sts?

I've read many reviews and I agree that the ride is a little firmer than my 2001 SLS. I'm not used to a bumpier ride, but I'm getting used to it. The mileage is 13 in town and 19 on the road with high test and Cadillac recommended fuel (Texaco). I test drove an 80,000 mile BMW 750i before and it was much nicer, but it was also the same price. The STS V-8 retails for $101K now, but it's easily $68K. For my next car, I'm considering AWD.
Ezra Kertzmann 2025-06-17

This car has a lot of potential, but unfortunately my experience with it has been disappointing. The quality of the car and the dealer service have not met my expectations. I have had several breakdowns that required tows and the repeated problems have not been resolved by the dealer. This is not what I would expect from a car like this. Additionally, the transmission can be rough and uncertain at low speeds and the electronics have not worked as advertised or designed.
Dante Fadel 2025-06-07
Vehicle year: 2005
Although there were some issues with the car's performance, I have identified some areas that can be improved. The ride could be made more comfortable, and the excessive road noise at highway speeds needs to be addressed. Additionally, the front end could be made more stable when going over small speed bumps. The front struts were replaced shortly after purchase, which helped to improve the car's performance. I also noticed that there is a difference in tire size between the front and rear, which negates tire rotation. Finally, I have observed that the car averages about 14 mpg in city driving, which is lower than the advertised 17 mpg. These issues need to be addressed in order to improve the car's overall performance.
Axel Watsica 2025-06-06
Vehicle year: 2006
Hey there! I hope you're doing well. I wanted to share some thoughts on the 2006 STS. While it's a great car overall, there are a few things that could be improved. For example, the foot-well is quite cramped, which can be uncomfortable for taller drivers like myself. Additionally, the glove compartment is a bit small for such a large car - once you've got the owner's manual in there, there's not much room left! Finally, the trunk access could be better, and the dash design is a bit bland. Overall though, it's still a great car!
Alexandro Herzog 2025-05-02

The car is fun to drive and has great potential, but unfortunately, I have had some issues with it. I have had to take my brand new STS in for service twice in the last three months for different problems. I feel that the service I received from GM and Cadillac did not meet my expectations for a high-end product. I believe that other high-end imports are more reliable and offer better customer service. Overall, I am disappointed with my experience and will not be purchasing a GM product again.
