While i was driving on the highway at 85 mph the truck went into limp mode causing the truck to slow down at a dangerous distance. My body was forced forward causing me to lose a portion of control and causing other drivers behind me to slam on their breaks. I pulled over and turned it off for a few minutes then resumed my travel. About 30 minutes later it happened again at 80 mph the exact same way. After taking it to the dealership they said it was a faulty solenoid in the valve body.

Feb 4, 2026Forward collision avoidance › Automatic emergency braking
The automatic emergency braking system on our 2023 GMC Canyon engaged suddenly 3 separate times while we were driving at around 50 MPH on a clear, straight road with no obstructions. We brought the truck to the dealership the next day, and the service department said it was a software issue and reprogrammed the truck's computer. This did not fix the problem, and we experienced the same unexpected automatic braking while driving at 50 MPH on a clear road. We brought the truck to the dealer again, and it has remained there ever since. This poses a risk for sudden unexpected stops, loss of control of the vehicle and rear end collision. There were no warning lights to indicate a problem. In…

The second time the vehicle was taken to the dealer, it was determined that there was a failure with the transmission caused by an inoperable wiring harness connection. The vehicle was repaired. The failure persisted, and the vehicle was taken to the dealer a third time but had not been diagnosed or repaired. The…
