The brake by wire system failed, and another component caused the vehicle to accelerate when I hit the brake pedal. I didn't have any proof on the last complaint, but I have it now. This brake failure caused me to rear end someone, which caused a multiple vehicle accident. The dealership I took it to was aware that I was having electrical issues with the car, but they said they couldn't do anything about it because they couldn't find any fault codes. I even sent them a video of it as well. I also believe this car was involved in a prior accident as well by one of the previous owners and fixed by one of them under the table, because the front bumper shock absorber plate broke in half, and had writing on it as well that looked like something a repair shop would do. This car is unsafe.
