Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
hi there. I am Cam. With the noise, do you need to be moving to hear the noise? Are there any warning lights on in the dash?
Ok, this does not sound like an electrical issue on the surface. It sounds like you might have 2 issues. It is most common to have a rock in the brakes that causes noise only in reverse.
As for the sensors in the rear, do you not get the lights on either? If you have it running and in reverse, and someone walks behind, it does not make noise?
Ok, Again my bet is a rock in the brakes then for the sensors, possibly a wiring issue at the sensor in the bumper. Please let me know what you find.
