When I am driving down any road, stopped and turning the abs system engages causing grinding noise. Loss of power and periodically brakes lock up and gas pedal locks. When pulling off from a stop I can not accelerate & rpm goes almost red line, car starts to jerk and and transmission doesn't shift. I have to let off gas pedal and allow to shift. It has stalled numorus times when pulling into traffic and almost caused me to be hit. The service traction control/abs warning light dings and stays lit. I manually turn off abs but problem still occurs. Also the wiring thru out the car has failed to my rearview mirror, domelights and radio panel. My gas mileage has significantly decreased. The problem started around the beginning of the year and has progressively gotten worse to the point I and scared to drive my car.
