2020 Cadillac CT5 Engine problems

lights illuminated on the instrument cluster. The contact was able to clear the codes, and then the vehicle was driven to a dealer. The dealer checked and saw that the VIN was included in NHTSA Campaign Number: 25V148000 (Power Train) and proceeded to reflash the Power Control Module and install the transmission monitoring software. 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.

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.

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.

(P0451): •A fuel tank pressure sensor malfunctioned, triggering a check engine light shortly after purchase. This affects emissions and presents a fire risk due to potential fuel vapor leaks. •The issue was confirmed by the dealer. 3. Camshaft Solenoid Failure (P0027): •A camshaft solenoid failure was repaired by the dealer, but was not disclosed to me at purchase. •This could have caused engine stalling or hesitation. ⸻ Has the Issue Been Confirmed? •Yes, all issues have been confirmed by the dealership. The vehicle has been returned for repairs, and I can provide diagnostic and repair records. ⸻ Safety Risk and Urgency: The transmission failure almost caused a serious accident on a highway. These defects present imminent safety risks that need investigation. I believe other owners may face similar issues. ⸻ Request for NHTSA Action: Please investigate these defects in the 2020 Cadillac CT5, particularly the transmission pump failure, EVAP system, and engine stalling risks. Thank you for your attention to this matter. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

when the light were actively on. I expressed to them as well as GM that I felt unsafe driving my vehicle this way as it is a great danger to my safety when the car looses power. I drive up/down a canyon as early as 3am I went from speeds of 80mph drooped down to 20-25mph due to this failure. Today I have another check engine light on the vehicle. I dont feel safe driving this vehicle at all!
