Structure
16 reports1 fire
“The contact owns a 2004 GMC Canyon. The contact stated that after work was completed on the tires, the independent mechanic informed him that due to severe undercarriage corrosion, the vehicle was unsafe to drive. The contact also took the vehicle to a dealer who provided the same information as the independent mechanic. The manufacturer was then notified of the failure and informed him that there were no open recalls on the vehicle. No additional assistance was offered. The vehicle was not repaired. The failure mileage was approximately 89,000.”

THE BRAKE LIGHT OUT WAS A SAFETY CONCERN FOR TAILGATERS. SO I TOOK TO MARK CHRISTOPHER GMC DEALER, ONTARIO CA FOR REPAIR BECAUSE OF TWO SAME RECALLS ON THE VEHICLE PLUS TRANSMISSION OIL CHANGE. ORIGINAL ESTIMATION OF COST WAS 305. THE DEALER DECIDED TO CHARGE ME 155 FOR TRANSMISSION OIL CHANGE AND LABOR, $16.75 FOR A DEFECTIVE/MALFUNCTION BRAKE SWITCH AND $200 ON LABOR. THEY TOLD ME THE RECALLS WAS DONE ALREADY ON THE VEHICLE AND THERE IS NO WARRANTY ON THE SECOND ATTEMPT. THE FINAL ESTIMATION OF COST WAS $377. I DON'T RECALL THE DATE THAT IT WAS SERVICED. HOW CAN GMC ASSURES THAT THE VEHICLE RECALLS WAS DONE PROPERLY? I'M VERY DISAPPOINTED WITH GMC AND IT RECALLS. I FELT LIKE I GOT RIP OFF BY THE DEALER. BESIDE, I DON'T KNOW IF THEY EVER CHANGE MY TRANSMISSION OIL FILTER AND CASKET ALONG WITH THE TRANSMISSION OIL CHANGE. *TR”

DEALERSHIP JUST WANTS $$$$$ TO CHECK THE CODES AND MORE $$$$ TO REPAIR THE PROBLEM THAT IS OCCURRING FROM THEIR POOR DESIGN FROM WHAT I HAVE READ I AM NOT THE ONLY ONE THAT HAS THIS PROBLEM. I'M AFRAID THE AIR BAG WILL NOT WORK ON PASSENGER SIDE IF AN ACCIDENT HAPPENS? ALSO CHECKED THE WIRES UNDER SEAT AND THEY LOOK FINE?”
