Most Replaced Parts on the 2nd Gen Chevrolet Traverse (2018-2023)

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.

Glass and Wipers

The usual tell is chattering or streaking that returns within a week of new blades. This is one of the items where a towing or work truck and a commuter diverge sharply.

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

Worth knowing: GM wiper arms and blades are matched to the specific windshield curvature, and length is not the only variable.

Suspension

The usual tell is a clunk over expansion joints that you feel in the floor more than you hear. Heat is the accelerant on this one, which is why it shows up faster here than up north.

Common parts in this group: shocks, struts, control arms, ball joints, sway bar links.

Worth knowing: Ball joint and control arm geometry sets your alignment range, and an out-of-spec part can make a correct alignment impossible.

Electrical and Charging

The usual tell is warning lights that appear in clusters and then clear themselves. Owners who do mostly short trips see this sooner than the mileage suggests.

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.

Filters and Fluids

The usual tell is a slight hesitation on hard acceleration with a dirty air filter. This is one of the items where a towing or work truck and a commuter diverge sharply.

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.

Cooling System

The usual tell is having to top off the surge tank more than once a year. Catch it early and it is a parts bill. Ignore it and it becomes a parts and labor bill.

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.

Drivetrain and Transfer Case

The usual tell is vibration that appears above 55 mph and grows with speed. Catch it early and it is a parts bill. Ignore it and it becomes a parts and labor bill.

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.

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.

Everything here is available as a genuine GM part through our Chevrolet OEM parts catalog. If you would rather search directly, search for Traverse parts.
