2022 GMC Terrain Service and Repair Manual

This factory service and repair manual for the 2022 GMC Terrain is a single-engine book — the turbocharged 1.5L DOHC inline-four of 91 cubic inches — behind a five-trim lineup that now includes AT4 and Black Edition alongside Denali, SLE and SLT. All are the four-door sport utility. One power plant makes the engine chapters unambiguous: one set of clearances, one fuel and boost system, one diagnostic tree. Chassis, brake, restraint and body coverage follows, with published specifications, torque values and wiring diagrams for each system.

Known issues on the 2022 Terrain. The federal record carries two recalls for this year. The driver's seat can have a stripped or loose bolt at the height-adjust pivot on the seat frame, so the seat may not hold an occupant properly in a crash; and excessive powder coating on the rear lower child seat anchorage bars can prevent a child seat from being attached. Owners have logged 85 complaints, weighted toward the fuel and propulsion system and the fuel system, with the electrical system behind them — areas covered here through fuel delivery procedures and circuit diagnostics.
