Owner report 11045708 · 2017-11-13 (November 13, 2017)
MY FUEL PUMP AND INJECTORS FAILED WHILE I WAS DRIVING, STRANDING MY TRUCK IN THE MIDDLE OF TRAFFIC RIGHT WHERE A CITY STREET WAS CHANGING TO A COUNTRY ROAD. THE GMC DEALERSHIP FALSELY CLAIMED THAT THIS WAS CAUSED BY USING UNAPPROVED FUEL. THE FUEL I USED WAS B20 BIODIESEL, WITH 80% RENEWABLE DIESEL, WHICH MEETS DIESEL SPECIFICATIONS AND IS A LEGAL ROAD FUEL IN CALIFORNIA. THEY ALSO CLAIMED THAT A CASCADE OF OTHER PROBLEMS WERE ALL CAUSED BY MY FUEL AND REFUSED TO APPLY MY WARRANTY.

Owner report 11458816 · 2022-03-29 (March 29, 2022)
The vehicle experienced a catastrophic failure of the fuel pump while towing a horse trailer on a busy state highway. This was a major safety risk because the vehicle gave no warning before it just stop working. It was a miracle we were able to coast off the highway into a wide spot that was able to accommodate both the truck and the horse trailer. The truck only has 77,000 miles and we are being told that none of the repair is covered under warranty. We were also told that the fuel pump has completely contaminated the entire fuel systems,…

Owner report 10824723 · 2016-02-07 (February 7, 2016)
THE BIGGEST PROBLEM (OUT OF MANY) THAT MAKES THIS VEHICLE UNSAFE, STRESSFUL, AND DISCOMFORTING TO DRIVE IS HOW IT WILL RANDOMLY DECIDES TO RAISE THE IDLE TO 900+ RPM (IN GEAR) AND BASICALLY DRIVES IT'S SELF. DURING THIS CONDITION IT IS VERY DIFFICULT TO OPERATE VEHICLE. BECAUSE OF ITS RANDOM PATTERN IT CAUSED ME TO HAVE AN ACCIDENT THAT RESULTED IN $3500 IN BODY DAMAGE TO THE TRUCK. THANK GOD NO ONE WAS HURT. WEAR AND TEAR IS DRASTICALLY INCREASED AS THE VEHICLE IS TRYING TO DRIVE ON ITS OWN AS I'M TRYING TO STOP AT TRAFFIC LIGHT, STOP SIGNS…

Owner report 11540851 · 2023-08-25 (August 25, 2023)
Backing out of driveway, suddenly lost the transmission. I was stranded at about a 45-degree angle into the traffic lane. I had no gear position indication (an automatic) and couldn't move the truck under it's own power. Shut it off and restarted twice before I got it into "limp-mode" and, while abrupt and harsh, managed to get back into my driveway. Found fault code U0101, Lost Communication with TCM (Transmission Control Module). Had never heard that this has become a common problem. Discovered quickly GM has no parts available, no repairs av…
