The electronic exterior door handle on my CT5 has failed and raises a concern of what if there was an accident and nobody was able to open the door if I was unconscious. I believe that having a key access is not enough and there should be a mechanical exterior door handle instead of an electronic handle that fails and is costly to repair.

While slowing down vehicle felt as if it was put into park momentarily, which cause car to slide on ice. After reading the recall, I am certain that the transmission failed. Car was towed to Ray Skillman cheverolet on south post road in Indianapolis, to which they already ran the vin and agreed to perform the recall. After they realized it was a more serious problem than software, they refused to work on the vehicle. So they worked on it long enough to find out they would have to cover it, then denied that they would do any work. They stated that the title is branded. The BMV has no brands listed on title. The service guy Ryan laughed at me today when I stated that it was dangerous, and told me good luck getting some one to help if I filed a complaint. Regardless they won’t touch the car

While key FOB is operational, next to car door and under moderate temperature conditions, the exterior door handle(s) wont open the car door. The doors freeze, remain latched in place from the outside. The interior door handle on the same door remains operational. This makes it difficult to get into the vehicle to remove people from inside the car should dangerous conditions be present while they are unable to operate the interior handle themselves and/or its difficult to enter the vehicle for safety should dangerous conditions be present outside the vehicle. The doors are jammed, we cant get to you!! There are reports of this happening to all four doors. The dealership says the exterior door handle must be replaced for the door to open from the outside again and it is uncertain if the replacement handle has the defect corrected or not. The latch freeze could occur again, anytime unless the replacement is improved. My vehicle had only 8500 miles on it and the exterior handle failed on the front drivers side. How many times will this condition repeat itself without warning during the lifetime of the car. CadillacForum has discussion on the matter including how some with the problem are disassembling the part and “repairing” the handle defect from the inside. This unnecessary risk could develop into an event that contributed to injuries. A reliable part must be installed asap though many cannot afford the $480 expense to replace it at the dealership. I had a 2000 Cadillac CTS for 20 years and didn’t have a problem with doors locking up from the outside - door handles not responding to efforts to open the door with a correct and operational key fob present.

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
