GMC Canyon 2015-2022: The Parts That Actually Wear Out

The Canyon 2nd Gen ran from 2015-2022 and is midsize with the available Duramax 2.8. After enough of these come across the parts counter you start to see the same short list of components over and over. Here is what owners of this generation actually end up buying, and what to know before you order.

Ignition and Engine Management

The usual tell is a misfire code that follows the coil when you swap it to another cylinder. Mileage is a rough guide here. Load, heat and road surface matter more.

Common parts in this group: spark plugs, ignition coils, camshaft position sensors, crankshaft position sensors, oxygen sensors.

Worth knowing: Oxygen sensor response time is what the fuel trim strategy is built around; slow generic sensors cause driveability problems that never set a clean code.

Body and Exterior

The usual tell is a window that drops into the door or moves crookedly. How the vehicle gets used moves this interval more than the odometer does.

Common parts in this group: mirrors, door handles, grilles, bumper covers, headlamps.

Worth knowing: Factory paint codes only work if the substrate and primer are the same.

Filters and Fluids

The usual tell is a slight hesitation on hard acceleration with a dirty air filter. Heat is the accelerant on this one, which is why it shows up faster here than up north.

Common parts in this group: oil filters, air filters, cabin air filters, fuel filters, transmission filters.

Worth knowing: GM oil filters are built to a specific bypass pressure and anti-drainback valve spec, which matters most on cold starts.

Electrical and Charging

The usual tell is the auto stop-start feature quietly deactivating itself. The number in the manual assumes conditions most people in North Texas do not have.

Common parts in this group: batteries, battery cables, alternators, starters, body control modules.

Worth knowing: Many recent GM vehicles need the new battery registered to the module or the charging system will keep undercharging it.

Heating and Air Conditioning

The usual tell is a clicking or ticking behind the dash when you change temperature. This is one of the items where a towing or work truck and a commuter diverge sharply.

Common parts in this group: cabin air filters, blower motors, blower motor resistors, A/C compressors, condensers.

Worth knowing: R-1234yf systems on newer GM vehicles use different oils and fittings than older R-134a systems.

Cooling System

The usual tell is the sweet smell of coolant after shutdown with no visible puddle. Owners who do mostly short trips see this sooner than the mileage suggests.

Common parts in this group: radiators, water pumps, thermostats, coolant hoses, cooling fans.

Worth knowing: Surge tanks and caps are pressure-rated to the specific system, and a wrong cap is a slow way to cook a head gasket.

Before You Order

Have the VIN ready. On a Canyon the same model year can carry two or three different engines and several suspension packages.
Check the SPID label in the glove box or console for your RPO codes.
Front and rear parts are rarely the same number, even when they look identical.
If the part is electrical, confirm the fit before you order. Electrical parts are not returnable at any GM dealer, including us.
