Bout last week my “Brake Failure stop safely” light came on and all gauges went to zero. Parked car turned car off and back on it went away. The next day message popped up again and car was still parked. Engine started to rev itself and car started shaking. Been having this problem last couple days. Then today as I’m driving it seem as if my gas peddle didn’t work anymore and the car wouldn’t go. I cut car off cut it back on. When I did that it continue to jerk as I drive and basically seemed like it could drive by itself. On the dashboard it may say I’m parked but I’m in drive or in reverse but I’m parked. Just need to know Wea I should start looking at for the main cause of this
