NHTSA Complaint #10491437 — 2012 GMC SIERRA

APPARENTLY GM USES PEANUT OIL TO LUBRICATE WIRING SO THEY CAN MORE EASILY INSULATE, ETC (ACCORGING TO THE GM DEALER). THIS ATTRACTS RATS AND MICE WHICH CHEW UP THE WIRING - POTENTIALLY IMPACTING SENSORS AND OTHER ITEMS CONTROLLING CRUISE, STABILITY/TRACTION CONTROL, AND ANY NUMBER OF ELECTRICAL SYSTEMS THAT THE DRIVER MAY BE RELYING UPON FOR SAFETY. I ACTUALLY HAD MAP SENSOR WIRES CHEWED UP THAT DISABLED MY STABILITY/TRACTION SYSTEMS AND INHIBITED ENGINE PERFORMANCE. LUCKILY FOR ME IT HAPPENED IN MY DRIVEWAY RATHER THAN ON THE HIGHWAY. DEALER CLAIMS IT IS NOT WARRANTY ITEM EVEN THOUGH CAUSED BY A PROCESS THAT GM ELECTS TO USE IN BUILDING THE VEHICLE. THIS COULD IMPACT ANY/EVERY VEHICLE THAT GM BUILDS WITH USE OF PEANUT OIL (MAY INDEED BE ALL OF THEIR MODELS). *TR
