2018-2023 Chevrolet Traverse Parts Guide: What Owners Replace First

The Traverse 2nd Gen ran from 2018-2023 and is C1XX platform three-row. 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.

Electrical and Charging

The usual tell is warning lights that appear in clusters and then clear themselves. How the vehicle gets used moves this interval more than the odometer does.

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

Worth knowing: GM’s battery management system is calibrated to a specific battery chemistry, group size and reserve capacity.

Ignition and Engine Management

The usual tell is a misfire code that follows the coil when you swap it to another cylinder. The number in the manual assumes conditions most people in North Texas do not have.

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.

Filters and Fluids

The usual tell is a slight hesitation on hard acceleration with a dirty air filter. Mileage is a rough guide here. Load, heat and road surface matter more.

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

Worth knowing: Dexos1 and dexos2 licensing exists because GM engines have specific requirements, and warranty language references it directly.

Drivetrain and Transfer Case

The usual tell is a four wheel drive light that flashes and never engages. This is one of the items where a towing or work truck and a commuter diverge sharply.

Common parts in this group: transfer case encoder motors, front differential actuators, u-joints, CV axles, driveshaft center bearings.

Worth knowing: Transfer case shift motors and encoders are matched to the specific case, and the module reads their position directly.

Brakes

The usual tell is a pedal that sits lower than it used to, or sinks slowly at a stoplight. Owners who do mostly short trips see this sooner than the mileage suggests.

Common parts in this group: brake pads, brake rotors, brake calipers, brake hoses, wheel speed sensors.

Worth knowing: Pad compound changes brake torque, and brake torque is one of the inputs the stability control system assumes it knows.

Sensors, Cameras and Driver Assistance

The usual tell is a backup camera image that flickers, goes blue, or shows lines. How the vehicle gets used moves this interval more than the odometer does.

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

Worth knowing: Camera and radar aim is a service procedure, not a bolt-on.

Before You Order

Have the VIN ready. On a Traverse 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 Chevrolet OEM parts catalog to shop by vehicle, or search for Traverse parts to go straight to a part.
