What owners report
I am filing an urgent consumer safety complaint against Bert Ogden Cadillac in [XXX] for a severe federal safety recall violation. My 2020 Cadillac CT5 is experiencing catastrophic transmission failure, including severe slipping and violent pulling during acceleration. This creates an immediate risk of sudden highway drive-wheel lock-up as warned under active GM Recall N242480630.On XXX, I brought the vehicle to Bert Ogden Cadillac and explicitly raised the transmission recall. The service agent, Patty, dismissed the recall, illegally charged me a $252.71 diagnostic fee for an active safety campaign, and turned me away with an out-of-pocket repair estimate of $12,138.80, which I could not af
The contact owns a 2020 Cadillac CT5. The contact stated that while the vehicle was parked and using the key fob to open the door, the door on the driverâs side failed to open. The failure was a recurring failure. The dealer was contacted and diagnosed the vehicle with an exterior door handle failure on the driverâs side. The manufacturer was not made aware of the failure. The failure mileage was approximately 46,000.
Electronic door hand on the drivers side completely stopped working, with little warning. This includes the proximity unlock feature and unlocking the car with the fob. If this were to have happened to all four doors at once, it would have been impossible to enter the car without breaking the glass. This is not safe.
There is some type of mechanical or electrical malfunction with the door locking system. I can not unlock or enter the car using the fan or by any mechanism from outside the car. This has left my fiance & infant trapped in the car. My fiance has to reach over and manually open the driver side door from inside the vehicle. However, I can no longer drive with only my infant in the car for fear she will be trapped inside.
Lockhart Cadillac Service Department committed warranty fraud by charging me on multiple occasions for repairs that should have been covered under GM/Cadillac 2025 Transmission Recall & Special Extended Warranties. The transmission has continued to deteriorate. I took the vehicle in on July 1, 2026 for recall service and was told it needed a valve body replacement. However, they are demanding again that I pay for it and refusing to submit it as a recall repair. They have had my vehicle 15 days and refuse to provide written documentation of actual diagnosis, TAC has not been submitted, they have not provided GM/Cadillac or myself with any written documentation as to why it wouldnât be cover
