NHTSA Complaint #11587903 — 2024 CADILLAC LYRIQ

Without warning and while driving this vehicle on expressway, I've received the following notifications several times: "Brake Failure" (car brakes on its own); "Service Stability and Auto Hold"; and "High Voltage" and Battery. Brakes, speed, steering, parking systems and camera do not work properly. Car's capacity to drive vehicle safely is reduced significantly - speed to drive car is immediately reduced and is limited without warning. Car shakes passengers violently (whiplash) when it believes there are people or objects in its path when there is nothing there and does not work properly when pedestrians are around the vehicle. During the incidents both my safety and other drivers safety are at risk - I am afraid to drive this vehicle although the dealership has indicated they have corrected the errors.Vehicle purchased 23 Oct - problems began around 2300 miles and have continued thru 4200 miles.
