The 2015 through 2022 model year GMC Canyon midsize pickup is included in a customer satisfaction program issued by GM for certain units of the truck, which have a mislabeled base front differential carrier.
GMC Canyon units affected by the problem were produced with the top surface of the front differential housing pierced by a 12-millimeter, or half-inch, hole that should not be present on the model.
Before starting an inspection on a potentially involved 2015 to 2022 GMC Canyon truck, the dealership should check to see if the vehicle is marked “Open” on its Investigate Vehicle History screen. This screen can be found in the GM Global Warranty Management system. If marked “Open,” the Canyon is eligible for repair.
Service personnel should follow up with direct inspection of the front differential housing of the affected GMC Canyon to confirm the presence of an incorrect 12-millimeter hole. If the hole is found, the dealer is instructed by GM to complete the repair as described.
Repairing GMC Canyon trucks with the incorrectly labeled front differential housing and the 12-millimeter hole involves rebuilding the front axle with the proper housing. The dealership will need all standard differential parts as well as front axle components such as clutch shaft parts, clutch fork parts, and inner shaft parts.
The customer satisfaction program is already active. It will continue to be active through September 30th, 2025. Owners of affected 2015 to 2022 GMC Canyon trucks receive the fix free of charge.
Meanwhile, Chevy Colorado units produced during the 2015 through 2022 model years may also have the same incorrect differential housing, with eligibility for a similar dealer fix.
Owners of possibly involved 2015 through 2022 GMC Canyon trucks can reach out to GMC customer service at the toll-free telephone number provided below, referencing the GM program number as needed, if they have questions or concerns:

The 2015 through 2022 model years encompass the whole second generation of the GMC Canyon, from its debut with the 2015 GMC Canyon to its final year as the 2022 GMC Canyon. Affected units with the incorrect front differential housing were produced after the 2021 GMC Canyon mid-cycle refresh as well.
The nameplate’s third generation debuted with the 2023 GMC Canyon, bringing a thorough overhaul and a slew of updates. There are highlighted by exterior aesthetic and dimensional changes, the reveal of the off-road ready 2023 GMC Canyon AT4X trim level, a revised cockpit, a new powertrain, and new technology.
