Valve body was replaced after bucking upon start up, and harsh/aggressive buck on downshift to low gears. Issue was resolved initially but came back within 3-4 weeks of repair. Bucking on downshift while braking has almost caused near accidents, and led to unpredictable transmission bucking while driving. Others who I know personally have had similar issues, one of which had a full transmission replacement. This occurs on the highway, or during fast deceleration such as a sudden stop, and the bucking lunges the car forward even after stopped. No warning on dash.

Defect investigations
Electronic Brake Module Component Failure
On April 11, 2024, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE24011 after receiving complaints concerning a loss of brake assist in 2023 MY Cadillac Lyriq vehicles. These complaints allege a hard brake pedal, followed by a “Brake System Failure” message at start up or while driving. GM shared records regarding several internal investigations for loss of brake assist due to alleged spindle fractures in the eBoost system. GM has stated that in the event of a spindle fracture, anti-lock brakes (ABS), stability control, and traction control remain functional until the vehicle comes to a complete stop. At this point, ABS, brake assist, stability control, and traction control functions are lost. The loss of these functions causes the vehicle to set one of three Diagnostic Trouble Codes (DTCs) based on failed performance criteria for the Electronic Brake Control Module (EBCM). These DTCs, in turn, activate several driver alerts: an audible chime, a visual “Service Brake System” message in the display, and multiple illuminated Malfunction Indicator Lights (MILs) for the ABS, Traction Control, and Brakes informing the driver of loss of functionality. The vehicle speed will also be limited to 70 KPH (43 MPH). Since opening PE24011, ODI has continued to receive reports of loss of brake assist. Some of these reports describe symptoms inconsistent with GM’s description of a spindle failure. These reports allege an immediate loss of brake assist functionality as opposed to the loss occurring after the vehicle comes to a complete stop. The sudden loss of brake assist during a braking event could result in extended braking distance, which increases the risk of a crash or injury. ODI believes further analysis is necessary to assess the potential for failures in GM’s eBoost system to resulting in safety-related outcomes. At this time, ODI is aware of the following vehicles that are equipped with this eBoost system: 2023-2026 MY Cadillac Lyriq, Chevrolet Colorado, and GMC Canyon; 2024-2026 MY Buick Enclave, Envision; Chevrolet Blazer EV, Equinox EV, Traverse; Cruise Origin; and GMC Acadia; 2025-2026 MY Cadillac Celestiq and Optiq. ODI is also aware of 2024-2026 MY Acura ZDX and 2024-2026 MY Honda Prologue vehicles that were built with this system. The Acura and Honda vehicles were manufactured by GM in a joint venture with Honda, and will be included in the Engineering Analysis as peer vehicles. ODI is opening this Engineering Analysis to further assess the safety-related consequences of a failed eBoost system. In addition, ODI is expanding the scope of the investigation to encompass all GM vehicles that share this eBoost system.

What 2023 GMC Canyon owners say
Most recent owner complaints, unedited.
Vehicle had brake system failure while driving nearly resulting in two accidents due to an inability to deccelerate. Brake System Failure notification came on screen along with other safety warnings and a check engine light has stayed on since.
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.
The contact owns a 2023 GMC Canyon. 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 contact depressed the brake pedal to the floor; however, the vehicle only decelerated to 15 MPH and failed to come to a complete stop. The instrument panel screen blacked out twice before the vehicle eventually rolled to a stop. The Forward Collision Unavailable warning message and Check Engine light then illuminated. The contact activated the hazard lights and drove at 5 MPH to a nearby parking lot. The contact stated the brakes continued to malfunction, requiring the driver to allow the vehicle to roll to a stop. The dealer was notified of the failure and confirmed there were no open recalls associated with the VIN. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 39,000.

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.
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.
