GMC Acadia 2017-2023: The Parts That Actually Wear Out

The Acadia 2nd Gen ran from 2017-2023 and is the smaller Acadia. 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 rough idle that smooths out above 2,000 rpm. Catch it early and it is a parts bill. Ignore it and it becomes a parts and labor bill.

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

Worth knowing: Coil primary resistance affects dwell, and the ECM is calibrated for the factory value.

Cooling System

The usual tell is having to top off the surge tank more than once a year. Worth checking at the same time you rotate tires, since the wheel is already off.

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

Worth knowing: GM cooling systems are DEX-COOL based and the seal and gasket materials are chosen for that chemistry.

Interior

The usual tell is a console lid hinge that has cracked at the pivot. Catch it early and it is a parts bill. Ignore it and it becomes a parts and labor bill.

Common parts in this group: floor liners, carpet floor mats, console lids, seat covers, shift knobs.

Worth knowing: Genuine trim matches grain and color code, which universal parts never quite do.

Glass and Wipers

The usual tell is a rain sensing system that triggers late or not at all. How the vehicle gets used moves this interval more than the odometer does.

Common parts in this group: wiper blades, wiper transmissions, wiper motors, washer pumps, rain sensors.

Worth knowing: Vehicles with rain sensing or heated wiper park use different assemblies.

Sensors, Cameras and Driver Assistance

The usual tell is a park assist system that disables itself in cold weather and comes back warm. Mileage is a rough guide here. Load, heat and road surface matter more.

Common parts in this group: park assist sensors, backup cameras, blind zone modules, front camera modules, radar sensors.

Worth knowing: These are calibrated devices, and the calibration lives in the module that expects a specific sensor.

Body and Exterior

The usual tell is a window that drops into the door or moves crookedly. This is one of the items where a towing or work truck and a commuter diverge sharply.

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

Worth knowing: Body panels and lamps have to match the vehicle’s specific mounting points and, on lamps, the exact photometric pattern that was certified.

Before You Order

Have the VIN ready. On a Acadia 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.

Ordering is easiest if you have the VIN in front of you. Head to our GMC OEM parts catalog to shop by vehicle, or search for Acadia parts to go straight to a part.
