GM refuses to repair the defective finish on my truck, their claim is that it only applies to trucks covered under the 3 year -36k warranty. This is a manufacturing defect that they admit to in the attached TSB. There should be a recall mandated for this. We spent a ton of hard earned money on these trucks.

2014 GMC Sierra 2500HD. My dash has started to crack around the passenger airbag and driverside gauge cluster. Dash material is brittle and serves as a hazard should the airbags deploy during an accident.

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 available, and that it is happening to thousands of GM trucks from model years 2008 to 2015. The truck is useless without this module function. We use…

2014 Sierra 2500HD SN ([XXX]) Leaving on vacation towing camper with family Bosch CP4 fuel pump issue left me stranded on a HWY 9 just outside Clinton, AR which is a 2 lane HWY with no shoulder. The vehicle gave me no prior warning, dash board suddenly read power restricted followed immediately with complete power loss as I reached to top of hill. I was forced to steer and brake the truck and camper with no power, down the hill to prevent vehicles from passing at crest of hill. This left me and my family and numerous other drivers in a very dangerous situation as cars tried to pass. I had to open the hood and try to determine what was going on. I directed traffic until a Van Buren County,…

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, including the injectors so everything must be replaced. The quote we received from the dealership for this massive repair is $12,208.59. No warning…

I OWN A 2014 GMC SIERRA 2500HD. IT IS IN VERY GOOD CONDITION AND WELL MAINTAINED WITH LESS THAN 140,000 ON IT. ONE DAY AFTER WORK I GOT INTO MY TRUCK AND AS SOON AS I STARTED IT I HEARD MY DASH CRACK. IT CRACKED JUST TO THE RIGHT OF THE INSTRUMENT PANEL BY THE DASH VENT AND WINDSHIELD. AND HAS BEEN GROWING EVER SINCE. IF THE DASH IS THIS BRITTLE IN A TRUCK THAT IS ONLY 6 YEARS OLD AND BEEN VERY WELL TAKEN CARE OF IT IS A SAFETY ISSUE. IF I WERE TO GET INTO A CRASH AND MY AIRBAGS WERE TO DEPLOY, SHARDS OF HARD BRITTLE PLASTIC WOULD BE SENT THROUGH THE CAB POSSIBLY CAUSING MORE INJURIES.
