What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
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.
The contact stated that while driving at approximately 50 MPH, the anti-lock braking system, brake warning light, low oil, low fuel, seat belt warning light, parking brake, temperature gauge, forward collision warning, and various other warning lights and messages illuminated.
The vehicle’s headlights are malfunctioning, creating a safety concern. The issue was reported to the dealership and GMC Customer Care, but it remains unresolved. The dealership offered repair assistance, but GMC Customer Care stated that no additional assistance is available.
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 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.
Trailer brakes continuously fault due to known problem GM technical bulletin 23-NA-149 This should be a recall. Nothing but the runaround getting it fixed by GM.
While driving I saw smoke and when I pulled over I seen fuel leaking from the gas tank area. Where it was leaking it ignited and the fire department had to put out the fire and the truck is totaled
Coolant leak observed at the upper radiator hose quick-connect fitting. The leak appears to originate from the internal seal at the radiator inlet connection. This issue developed without warning and is consistent with a known defect in the radiator hose seal design used in 2023 GMC Canyon vehicles.
