What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
My car was hit from behind very hard and my head hit the steering wheel. The whole back was crushed and the airbagss did not deploy.
A warning vibration is felt just before the car struck the device but the way I understand it in the owners manual the car should come to a complete emergency stop. This could endanger anyone or anything that the driver did not see while moving the car, i.e., a child on a tricycle for example.
Rough idle, reduced acceleration, engine failure requires engine/motor to be replaced. Only 4300 miles on car. Purchase date 6/21/2025. Failure10/25/2025.
I went to test drive this car on Saturday 9/27, and noticed that the rear view mirror--the actual mirror, not the video screen inside it--was vibrating/shaking immensely as I drove it. I told them I'd buy the car, but they have to fix the mirror.
I just bought a new car 5 days ago, and after running 378 miles, it started to pull the cylinder. The after-sales service is still delaying the time. I don't know what to do, and Cadillac still doesn't give me a mobility scooter.
This new 2025 Cadillac CT5 displays incorrect posted speed limits on Rte. [address], Gulf Rd, Bear hill Rd , .Ryan Rd, in Henniker NH. speed of 55mph which is incorrect to legal posted speed limits being much slower.
