2024 Cadillac XT4 Engine Problems

“Driving to a local car wash, I stopped at a traffic light. When I tried to accelerate the transmission warning and power reduction waring flashed on HUD. I could not drive or place the car in reverse, the car had lost all its mobility. I had to let the car coast downhill to pull the car to the side of a busy street. I was fortunate this did not happen on a congested highway, but regardless the inability to move a car off a busy street is an extreme safety hazard. …”

“On June 13th 2024, and on July 30th 2024, while driving on highway my Cadillac XT4 suddenly jerked forward as if I had been struck from behind by another vehicle.

“I am reporting a serious safety issue with my vehicle, purchased from Ed Morse Cadillac. The vehicle has unexpectedly shut off while I was driving on multiple occasions (3 times to date).
