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.
The contact owns a 2003 Chevrolet Impala. While driving approximately 45 mph, the contact smelled burning wires. The vehicle was merged to the side of the road and the steering column was smoking. The fire department disconnected the battery. The vehicle was towed to an independent mechanic. The technician replaced the wiring harness and the combination switch. The manufacturer was not notified. The approximate failure mileage was 137,400.
Traction control light and abs light both can come on at intermittent times. Both happen when turning into or backing out of a parking space in any sort of weather including perfectly dry cement. I have been told that this problem has lead to accidents with individuals because you don't get the full breaking power when making turns. This happens also when making slow turns around any corner. The problem is now happening almost all of the time when making turns. I have been told to replace my front hubs as well as the wiring harnesses but I have been reading up on it and have seen that none of those things have worked for anyone and the problem continues to come back after spending over $1000 dollars.
: the contact stated the abs and traction control intermittently stop working. The abs and traction control lamps illuminated before the systems would fail. The vehicle was taken to the dealer for inspection and repairs. The dealer discovered the wiring harness had rusted and caused the systems to fail. The wiring harness was replaced and the vehicle operates normally.
