2017 Cadillac CTS Complaints

The airbag warning light appeared 45 days ago. I immediately took my 2017 Cadillac to the dealer (Sewell Cadillac of Houston). The vehicle is covered under a Sewell Extended warranty until 2028. The dealer performed troubleshooting and determined that the passenger seat sensors/module (part # 84567224 ) was defective. The Inspector for the Sewell Extended warranty confirmed that the replacement was covered by the warranty. The dealer advised after 30 days (completing other services- Brakes/rotors/front tires/spark plugs & wires etc) that the part # was “Back-ordered” and Sewell did not know when the part would be available, if ever. The consequence explained that the passenger seat which contains GM Part # 84567224 should not be used as the airbag may not inflate. Now the dealer wants their “loaner car” back and for me to pick up my “unrepaired Safety defective seat in my car”. Today’s date: December 20, 2025. The car was purchased new 11/2016 from the same Sewell Cadillac dealer. I w...

The power steering went out on the vehicle. I was not driving at the time. There was a recall on these vehicles pertaining to the EPS module.

The Cadillac CUE screen cracks and becomes unresponsive. When driving this is effecting anything related to system including navigation, radio, hvac, phone and all other functions creating a distraction to the driver that could lead to an accident. This is not the first time that this has happened to me and I’ve noticed that each time the issue is created is during hot days in southern states. This has never happened during the winter. This is my 2nd Cadillac in a row that has had this problem repeatedly. Happens every 2 to 3 years. This might not seem like an issue but it poses a major safety hazard to all people in vehicles around them and an immediate recall and investigation should be taken seriously. A lawsuit was settled for some owners but all owners should be notified and repairs should be completed at the manufacturers expense regardless of age or mileage.

I purchased this vehicle is certified preowned Cadillac and during the warranty time I had a transmission issue that was causing the transmission to jerk when shifting from 1st to 2nd gear and at highway speeds, it would start jerking nonstop. I took it to the dealer and as per a service bulletin, they flushed the transmission fluid and replaced the transmission fluid. This was only a temporary fix because 30,000 miles later the same issues started occurring again and have gotten worse to the point that you can smell the transmission clutches burning and the transmission overheating, possibly causing the number four piston rings to come apart, resulting in an engine replacement as well. I’ve had to replace engine as possible result, but the transmission problem is still there and it has also caused the check engine light to come on intermediately. This could result in a complete transmission failure, causing a vehicle to lose propulsion leading to a possible accident and injuries. This...

OnStar is unable to communicate with my vehicle. When I bought the car 2 years ago, it connected fine. Not OnStar is unable to ping my car. Appears the. Module goes out on a lot of cars since I was told it is on back order and not sure if that was the true peoblem
