2020 Cadillac CT5 Power Train

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

Regarding NHTSA Campaign ID 25V148, GM recall N242480630. The recall was for a potential transmission control valve issue where some vehicles may be susceptible to excess wear over time, resulting in gradual loss of pressure within the valve that can cause harsh shifting. With the recall we finally knew what was wrong with the vehicle. We have a defective transmission control valve. The transmission was replaced in 2022 and now needs to be replaced again. At the appointment for the recall we expressed that the transmission control valve has already caused damage and it needs to be replaced. We also requested that the damage the defective valve caused, the failing transmission, also needs to be replaced under this recall. We were told to contact Cadillac customer support at 800-333-4223 and filed a case on 5/27/25, case [XXX]. I have yet to receive a call back. I call everyday and leave a message and nobody calls back. The vehicle can not be driven and they will not provide a loaner car. Please hold Cadillac accountable for using defective parts in vehicles and then not providing a remedy to the damage they have caused in a timely manner if at all.
