Cadillac
Ct5

Door handle opening mechanism has not been working correctly for over a year. Multiple attempts to open the door will finally work and the door will open. This is a life safety issue that I have taken up with GM multiple times now and they refused to cover the vehicle. When looking online, dozens of other individuals have also complained about this exact issue.

The vehicle was repaired. The contact informed the dealer that the rear wheels had locked up and which indicated transmission damage. The dealer performed the recall repair and informed the contact that the vehicle was repaired. Additionally, the contact was advised that the engine was leaking engine oil. The vehicle was not diagnosed or repaired for the oil leak failure. The manufacturer was informed of the failure and advised the contact that there was no assistance that could be provided. The failure mileage was approximately 65,000.

For no apparent reason my vehicle is shifting itself into Neutral while driving. The car will suddenly completely slow down to a stop and in order to restart the car, I have to put it in park. It doesn't matter what speed or the road condition, it simply comes to a slow stop because it is no longer in driving mode, it has shifted itself into Neutral. The recall has been serviced and after more than 10 days of being in 2 different Cadillac service centers, I am advised they are unable to simulate the issue, thus the issue is not resolved. It is most definitely a safety issue because the vehicle will just stop moving with the flow of traffic. My concern is being rear-ended or having any type of accident since the car abruptly stops without warning.

CT5 2020 Doors will not unlock.

Major safety Concern Faulty valve body and transmission dealership failed to disclose. Service manager drove vehicle with bent wheels. That is how the bent wheels were discovered. Not from inspection. Wheels evidently bent under dealership possession. 2020 Cadillac CT5 Vehicle financed at 12K Miles with certified pre owned, bumper to bumper, and powertrain warranties in February 2024 showed poor driving, shifting, acceleration and abnormal behaviors such as slow and delayed shifting/acceleration, loud shifting, jerking, and strange noises from the vehicle and low power. There were very suspicious mechanical issues wrong with the car in which the dealership told me that there isn’t anything wrong with the car, with the understanding that if anything was ever wrong with the vehicle it has been fixed. I was ensured and promised that the car does not have anything wrong with it and that it goes through inspection and diagnostics, that the vehicle cannot be sold without being tested, fixed of any problems and brought to standard. I brought this to the attention of the salesman, owner, financial advisor, service advisor, service manager. I requested a full buyback and replacement of my 2020 CT5. My dealership let me know that they still want me to pay for the valve body, battery, ambient air temperature sensor and rear parking brake motor. I had to call Cadillac corporate/General Motors to have the valve body covered & rear bumper covered/replaced. I was brought into the dealership office and was told that the buyback and replacement was denied by General Motors even though my car was showing symptoms of a defective valve body ever since I financed the car. These things were being ignored by the dealership service department. Laggy and rough acceleration as well as shifting. Strange vibrations and noises coming from the car. Slow moving and the shifting was very jerky and abnormal. The shifting was also very loud and took long times to shift 1-2, 2-3, 3-4, 4-5 gears.

Two separate issues: One is being sold a vehicle with a Certified vehicle at 12K miles with a defective, faulty transmission which is a manufacturer defect from General Motors. 10-speed automatic transmission 10L90 model. Misrepresentation of a product. False advertisement of a product. Failure to disclose. Gross negligence. Unethical & Illegal business practices. Dealer & manufacturer fraud. Second issue: When Valve body was replaced on the vehicle, the service manager of the dealership test drove the vehicle with me in the passenger seat on the highway. The vehicle was still not shifting or accelerating correctly even after the valve body replacement. The vehicle began to shake, jerk and rumble on the test drive. The vehicle drove worse. The service manager and I took the vehicle back to the dealership and he found that two of the wheels, on the passenger side, are now bent. That is how the bent wheels were discovered. Not from inspection. Previous multipoint inspection and diagnosis shows the wheels were not bent before I brought the car into the dealership for mechanical work. I can attest to the fact that my wheels were not bent before service and this obvious shaking of the car was not previously existent. The dealership denies liability for this issue and is now refusing to replace the wheels after I have offered to pay. Dealership service manager told me it was safe to drive the vehicle with two bent wheels and I strongly disagree with that statement and so has my insurance company. It is very questionable as to why the service manager would make such a statement. The dealership told me to call other GM dealerships to have the wheels replaced. They refused to do the work as well. I am seeking the proper resolution in this situation.

I've owned 2 ct5 each one had their turbos go out at 55k miles each and valves bodies that need replacing around 70k for each vehicle
