On february 8, 2019, my mother was pulling into a maintenance garage to get an oil change. Upon pulling into the garage, she was unable to stop and her vehicle lunged forward. As a result, he vehicle hit an employee, went through the maintenance garage door, through the parking lot, across a four lane street, and eventually stopped in a field across the street from the oil change venue. This is an approximate distance of 300 feet. Upon further review by my mechanic, it was discovered the ABS system was malfunctioning causing the brake pedal to drop in the car, and the car not to stop. The wiring harness also was cracked resulting in a cut to the ABS wire, causing the ABS malfunction resulting in the car to not stop, and the electrical malfunction which caused the car to speed forward. General motors was notified, but denied responsibility of this claim.

While driving in town, making a legal u-turn at a safe speed, the power steering failed mid-turn and the car was very hard to control and the steering wheel jerked violently. It is unknown what caused the failure, however there is a recall on my vehicle concerning catastrophic steering failure. This steering failure was caused by faulty manufacturing/ equipment by gm.

When driving home from work, I was in the center lane of the highway, when there was a loss of power in my 04 grand prix, the display showed "loss of power to the engine" there were trucks on either side, luckily I was able to get to the side of the road by dodging the vehicles coming up behind me. I called my mechanic and explain the condition, he knew exactly what was wrong because he said he fixes them all the time. The speed sensor in the accelerator pedal losses connection with the throttle body and loss of power is the result. If this same problem occurred on a toyota they would have recalled the vehicles and fixed the problem. I guess gm has enough problems or maybe not enough people have died to make this a gm safety priority.

I first noticed that when turning there was a grinding noise. I took it to a shop and was told the front passenger control arm needed replaced. I recently took my car to the dealership for the ignition switch recall and found out that the speed harness needs replaced and that is what's causing the light for ABS/tc to be serviced. I have researched both of these issues with this specific vehicle and it appears to be a widespread issue. What constitutes a recall?
