2023 GMC Canyon Service and Repair Manual

This factory service and repair manual for the 2023 GMC Canyon covers a truck narrowed to a single engine and a single body: a turbocharged 2.7L DOHC inline-four of 166 cubic inches, in a four-door crew cab. Four trims are documented, AT4, AT4X, Denali and Elevation. With only one engine to describe, the coverage goes deep rather than wide, running from engine mechanical, fuel, emissions and cooling procedures through the torque values, wiring diagrams and diagnostics for every system on the vehicle.

Known issues on the 2023 Canyon. A front camera module that could read an obstacle where none existed and trigger automatic emergency braking, slowing or stopping the truck abruptly, heads the three recalls on this year's record. Another covers front wheel hub bolts over-tightened during installation, which could then loosen or break. The third concerns a front seat belt buckle attachment bolt left under-tightened. Of 60 owner complaints, the electrical system leads, with service brakes and the engine behind it. Driver assistance calibration, wheel end torque values and brake diagnostics all sit inside this manual's scope.
