CADILLAC Complaints

The onstar module has failed and this seems to be an ongoing issue with a lot of gm’s. My car was recently in to fix the major gm engine recall and after that my onstar stopped working. I called and they said it’s not a connectivity issue it’s a part issue. So it will have to be taken to the dealership. I pay money to have onstar and unlimited WiFi. There should be a recall for this.

The contact owns a 2016 Cadillac SRX. The contact received notification of NHTSA Campaign Number: 21V473000 (Suspension). The contact stated while driving 55 MPH, the steering wheel began shaking violently and the vehicle fishtailed and failed to steer as intended. The vehicle was steered to the side of the road and restarted. The vehicle was then taken back to the residence. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The thermostat sensor is defaulty. While driving all of the dashboard component lights flash on and off and the vehicle loses power while driving. Called the dealership and the technician knew exactly what it was because he said this is a known issue and when I got the vehicle to the dealership they didn't need to do a diagnostic, they knew exactly what it was. A recall should have happened to avoid this.

THIS IS AN ISSUE THAT HAS BEEN UNDER RECALL SINCE JUNE 2025. WE HAVE HAD THE DEALER DO THE RECALL, HAD OVER THE AIR UPDATES AND IT STILL CAUSES ALL THE ADVANCED DRIVER ASSISTANCE SYSTEM SCREEN TO GO BLACK AND DISABLES THEM. DEALER MSYATES ALL RECALLS HAVE BEEN COMPLETED.

At around 17,000 miles the timing chain tensioner went bad. At cold start up you could hear the timing chain hitting the 'guide' until the oil pressure built up and provided enough tension. I was covered by an aftermarket warranty - which paid all the labor ($1700). I had to pay a $100 deductible -along for the parts ($300). I feel that this should be looked into and Cadillac should replace any tensioner that might be defective- since this could cause catastrophic engine failure. If you check - it does appear the 'new tensioner' part number is a revision- indicating Cadillac probably knows the old part number was defective!

Rough idle, reduced acceleration, engine failure requires engine/motor to be replaced. Only 4300 miles on car. Purchase date 6/21/2025. Failure10/25/2025.

1.) Loud engine ticking and clicking noise when car is in park position. 2.) Vibration in steering wheel after numerous alignment and wheel balancing services. Even purchased 4 new tires and vibration still continues.

With only 78k miles on my 2017 Escalade the same issue happened with the lifters like in the 2021-2025 models. We had to pay out 14k to replace the motor. GM has known about this problem for almost a decade and it’s not fair that we had to pay out this much money to replace an engine with them knowing the problems. Had they told us years ago to change to a heavier oil or whatever we would have done so and maybe our factory engine would have lasted like so many previous year models up to 250k miles.

I purchased the car June 2025 ,The headlights go so dim that you can not see at night, I contacted Cadillac and they are only willing to give me $200. towards the $2000. repair it would cost even though the headlights used on the 2016 Cadillac SRX is the same ones that were recalled on the 2015. They said they have no more programs to help me fix this issues.

I was driving my 2022 Cadillac Escalade when suddenly the engine shut off. Lost the ability to drive forward and steering became hard. I was close to being rear-ended as I was on the highway. Towed it to the dealer who said engine seized. Installed new engine after a month of waiting and the vehicle doesn't run right. It has a rough idle. Dealer installed incorrect oil as replacement engines were supposed to retain original oil of 0W-20. Had to make numerous trips to the dealer due to low coolant, wrong oil on a new engine and rough idle. Dealer says its fine. $100K vehicle with a rough idle is a joke!
