GMC Complaints

my 2007.5 GMC Duramax has been parked for 1 month, had to barrow a truck to go to work, just not willing to pay the 1600-4500 dollars that suppliers or private sellers are asking for the TCM, tried a private seller on EBAY and it turned out to be a scam, local Dealership has no clue on ETA, I use my truck 6 days out of the week and now sitting not being moved may cause other issue when I do finally get it going again, the problem with my durumax is the TCM Transmission Control Module, I was already at home when issue started.

The contact owns a 2023 GMC Canyon. The contact stated while driving 20 MPH, while making a right turn, the left turn signal activated and blinked three times. The contact stated that the Adaptive Cruise Control intermittently activated the brakes independently, and the Forward Collision Avoidance system activated and forced the vehicle to stop abruptly, almost causing a crash. The Forward Collision Avoidance warning light was illuminated. The vehicle was not diagnosed or repaired by an independent mechanic or the dealer. The manufacturer was made aware of the failure and informed the contact that the parts to repair the vehicle were on backorder. The failure mileage was approximately 2,251.

Transmission Control Module failure The TCM went out one day with no warning. Sitting at a red light, the light turned green, I started to go, and got about 20 feet into the intersection when suddenly it was like my truck shifted into neutral gear. Motor would rev but I couldn't move forward or backward. I was stuck in the middle of a busy intersection. My check engine light came on and the vehicle stability control light began flashing, it was as if everything in my truck was going haywire. I turned my hazards on as vehicles were whizzing by us, barely missing us. My wife and I got out and with the help of a few other drivers we attempted to push the truck out of the roadway but it was too heavy. We got back in and when I started the truck, all the lights were still on but this time it went into gear and we were able to leave the intersection under our own power. I was able to drive the vehicle to the dealership in 2nd gear. Luckily it was close. They diagnosed the vehicle. Code U-0101 lost communication with TCM was the diagnosis. Unfortunately, that part was on back order and it took 9 months to get one. Dealership replaced the part and all has been we'll since then.

I have called and spoke with GMC in Gurnee Illinois and was told "there is no remedy for this recall". I will be driving upwards of 11 hours and feel it is unsafe and unreasonable for them to not change something that could be potentially deadly.

Driving on the expressway around 60 mph when the truck went into limp mode slowing me down to 40 and then would not shift gears Tcm went out gm told me that there is a big problem

I received a recall for my vehicle months ago due to an airbag issue. The recall states there may be metal fragments in my airbag. This makes the car unsafe to drive. GMC still has no estimated time frame for when the parts will be available. I can’t afford to go out and buy another car while this one just sits. I don’t know how I’m getting my child to and from school starting the day after tomorrow. GMC will not offer a courtesy car and will not buy back the vehicle. This is unacceptable that they just expect me to drive this vehicle knowing there is a chance the safety equipment could kill the occupants of the vehicle.

My car is giving me all kinds of warnings, parking assist off, rear back up, trailer brake, the radio sounds go off, blinker sounds go off, while trying to park power steering locks up, it will die in the middle of a turn. It’s doing everything The 2015 recall was created for. I do not think my car was fixed during the recall period. It is very hazardous.

TCM failed. Couldn’t find the parts required. Truck sat 700 miles away from me for four weeks. Had to have part repaired in hopes it worked. As of now I still have some issues but would not have the truck at all if I had to wait for a part
