2026 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.

Intermediate steering column defect causing a pronounced dashboard rattle. The dealer (Putnam GMC, Burlingame, CA) diagnosed the issue under warranty, but the required part is on national backorder with no ship date. The vehicle has been out of service at the dealership since September 2, 2026 awaiting the part. This is a steering-related defect on a brand-new vehicle with approximately 1,500 miles.

I’ve included all my repair orders regarding to coolant smell/leak and transmission shutter. I purchased my truck on XXX. We had planned a family vacation to [XXX], and we were driving up when I felt the transmission shutter at around 3:00 to 5:00 p.m. while cruising at approximately 55 to 62 mph. Since then, I’ve noticed it happening more frequently. I took the truck to GMC dealer Jack Hanaia at [XXX] (I believe it was in XXX). I expressed my concerns, and they couldn’t find any issues with the transmission, along with the coolant leak. They claimed they couldn’t find a leak, but the service advisor could smell a strong coolant leak. Later on March 5th the coolant leaked, and I got a different advisor. She could smell the leak but the tech couldn’t replicate the issue. A few months later, around August, I took the truck to a different dealership, the Buick GMC dealership at [XXX]. I informed them that I had a coolant leak smell, a transmission shutter, and other issues listed on the repair order They couldn’t find the transmission problem or the coolant leak, but the advisor could also smell the coolant leak. I’m getting tired of going to the dealership and getting a turnaround to go home with the same issue. I have issue with parking sensor blocked all the time. My AC issue is becoming more problem for me, the temp doesn’t match the reading with a thermometer, it’s way off to the point where I have to turn it to LoW to get max cold. When set at 65, it feels like 75 degree. I have videos. My last 2009 GMC Canyon 3.7 crew cab treated me and my family well for 13 years. I bought it in 2013 and sold it in XXX. I thought to choose GMC Canyon over Toyota Tacoma, but now that I’ve been experiencing this issue nonstop, I’m regretting the decision to pay the truck in full cash.

With 94 Miles my brand new GMC Canyon AT4 I leased had a catastrophic failure while i was driving it, the front axle essentially exploded. The findings were that their was no oil/lubricant installed in it from the factory which made this happen. I now have to wait many months for the dealership to repair my vehicle while i have a "loaner" with a bunch of restrictions on it. And i have to pay my lease the entire time it is being worked on because of a factory fault. If i had been going more than 25 mph this would have resulted in a crash/injury.
