2024 GMC Canyon

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.

I purchased my truck with 5 miles on the speedometer in Anchorage AK 4/7/2024. In May 2024, the engine idled rough and transmission shifted hard, I was told me it was normal, and I would have to wait 2 yrs to make a transmission appointment. In June 2024 approaching a green light, approximately 35 mph, the brakes locked, I had no control over the steering and it left a 5 foot skid mark. I had a painful neck and headaches. The shop said they couldn’t make it do it again. In August 2024 approaching a stoplight at 40 mph, the brakes locked, would not release, gas didn’t work, I had no control over steering this left 6-7 ft skid mark, The vehicle also had electrical issues the interior dash lights would go black, very bright, interior lights would flash, the radio would stop working. The manager took my truck home and said I should shut the forward collision and pedestrian warning system off. I was in communication with GM Customer care who informed me they could not help me. The dealership ran my truck into a cement post, causing $2000. Now sometimes the brakes randomly stop working, the throttle stuck open, and the trans is worse. It’s not safe to pull a trailer or take people with me. It’s out of warranty and dangerous. I drive on edge not knowing what’s next. It’s $8,200 to fix the transmission, the front radar camera needs replaced, and electrical fixed by a quality shop.

I first noticed the brakes squealing in August 2025 at 15,000 miles. The dealership said I needed to resurface the front rotors. I mistook this a coating and brake debris, but it was actually the rotors warping. By 21,000 the vehicle is pulsing heavily when stopping. I went back to the dealer and this time they told me all 4 rotors are warped. GM denied coverage of the pads and rotors. Normal driving, no collisions or towing.

Upper radiator hose connection to radiator is faulty causing leak of coolant. Yes it is available for inspection upon request. Truck began to run cooling fan at full speed in the middle of winter with no warnings of high heat or low coolant. After two weeks, check engine light finally cut on to indicate low coolant flow. Coolant reservoir was subsequently checked and found to be completely empty. It is apparent this reservoir had been extremely low / empty for at least two weeks with no warnings. Without proper warning and leaking coolant, truck could have overheated. Should this had happened in dead of summer, truck could have very well overheated with no warning. The problem was investigated and confirmed by dealer as leaking coolant at the connection of the upper radiator hose to the radiator. Was quoted $983 to replace the hose. No warning lights appeared until issue had been ongoing for over two weeks. A quick search of "GMC Canyon Upper Radiator Hose" will reveal many identical occurrences of this issue. This is a safety hazard / design flaw that GM is not acknowledging and is putting the burden on the vehicle owners for their own issue.

On 2 occasions the battery was drained and a tow truck had to jump the battery. On one occasion after the battery was jump started it took several hours before the brakes were able to be used and the car driven safely. Had to drive very slowly (under 50 mph) per note that appeared on dashboard. After nearly an hour of waiting Engine light stayed on and dealership ran diagnostic and found nothing wrong with the battery nor anything else. Have to start and run engine everyday to keep battery from dying. If not started in 24 to 36 hours, battery will die.
