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 addition, the blind spot indicator light on the drivers side starts blinking when there is nothing in the blind spot. We first notice the problem July 23, 2026 and it recurred on August 6 2026.

The contact owns a 2023 GMC Canyon. The contact stated that while driving approximately 15 - 20 MPH, the message to decelerate immediately was displayed on the instrument panel, and the transmission unexpectedly downshifted to 1st gear. The failure had occurred several times, at times while driving 75 MPH. The vehicle was taken to the dealer to replace the valve body and solenoid. 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 manufacturer was not made aware of the issue. The failure mileage was approximately 42,000.
