NHTSA Complaint #11542705 — 2013 GMC SIERRA 2500

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.
