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 afford. The dealer's own written service notes explicitly state: "customer will come back for recall," proving no work was performed.However, the online GM portal shows that the dealership subsequently went into the national database behind my back and fraudulently reported this identical safety recall as "Completed" on XXX.I contacted Cadillac Corporate on XXX, and they opened an internal investigation under GM Case Number XXX. However, corporate management was hostile, questioned the safety defect connection despite the matching codes (12CDZSERTA and 98CDZXOLK), and actively refused to dispatch a corporate flatbed tow for this disabled safety hazard. I have already filed a deceptive trade practices case with the XXX Attorney General under case XXX. I require immediate federal intervention to compel General Motors to tow and repair this hazardous vehicle at zero cost as mandated by federal law.

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.

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 wouldn’t be covered under warranty. They have not submitted the service history of the last 6 service repairs to GM/Cadillac as requested, nor have they offered me a courtesy vehicle or rental car compensation and virtually have left me stranded for 2 weeks.

The left passenger door will not open manually nor with key fob. It has caused me to not allow back seat passengers including grand children for fear if necessary to get out in an emergency and I am left to wonder if the driver door will go into lock position during a collision and that would be life threatening. I tried holding the lock and unlock at the same time for 3sec and that didn’t work. The dealership said it would cost around $800 or more to take the door off and try to find the problem and I would probably have to get a new door and try to match the paint. I really need help with this issue because I have less than 20,000 miles on my car. I have seen online that there’re many people dealing with this problem being it the back doors and some the front. These cars cost the customers a lot of money when purchasing them. I would greatly appreciate the issue being reviewed for recall repairs. Thanks

While driving my 2020 Cadillac CT5 at highway speeds, the vehicle suffered a sudden and dangerous total loss of motive power. The transmission completely failed without warning, creating an immediate, severe safety hazard as I was forced to navigate across multiple active lanes of high-speed highway traffic without acceleration.The vehicle was towed to an authorized Cadillac dealership. The technician's diagnostic inspection confirmed that the internal transmission pump drive gear completely shattered, sending catastrophic metal debris throughout the entire transmission system. The dealership has recommended a total transmission system replacement.This internal pump gear failure is a documented cascade consequence of a manufacturing defect in the Transmission Control Valve Body, which causes severe internal fluid pressure drops. This specific transmission defect is subject to GM Special Coverage Bulletin N242480631 and NHTSA Campaign Number 25V148 / GM Recall N242480630. The defective valve body starved the transmission of pressure, directly destroying the pump gear at highway speeds and putting my life in danger.

The rear passenger driver side outside door handle stopped working about 3 days ago. I have three small grandchildren and if there is an accident or any other emergency I cannot open the back door to get them or anyone out of the vehicle to safety, which can lead to bodily harm or worse. I have already had the driver outside door handle replaced on March 18 2025 for the same problem. There should be a recall on the door handles to prevent the chance of bodily harm upon anyone. Also, to prevent this from happening again, the door handles could possibly be replaced with regular door handles. Thank you
