Most Replaced Parts on the 2nd Gen Buick Enclave (2018-2023)

The Enclave 2nd Gen ran from 2018-2023 and is C1XX 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.

Sensors, Cameras and Driver Assistance

The usual tell is a TPMS light that will not clear after a tire rotation. Catch it early and it is a parts bill. Ignore it and it becomes a parts and labor bill.

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.

Drivetrain and Transfer Case

The usual tell is vibration that appears above 55 mph and grows with speed. Owners who do mostly short trips see this sooner than the mileage suggests.

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

Worth knowing: CV axle length and spline count vary by ride height package on the same truck.

Suspension

The usual tell is the nose diving noticeably further under braking than it did new. Catch it early and it is a parts bill. Ignore it and it becomes a parts and labor bill.

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

Worth knowing: Vehicles with adaptive or air suspension talk to the module, and non-OEM parts often will not report correctly.

Cooling System

The usual tell is crusty orange residue around a hose clamp or the surge tank seam. Heat is the accelerant on this one, which is why it shows up faster here than up north.

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.

Electrical and Charging

The usual tell is a battery that tests fine at the counter but fails after sitting three days. 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.

Filters and Fluids

The usual tell is reduced airflow from the vents. The number in the manual assumes conditions most people in North Texas do not have.

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.

Before You Order

Have the VIN ready. On a Enclave 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.

We stock genuine GM parts for every nameplate on this list and ship nationwide from Dallas. Start at our Buick OEM parts catalog, or search for Enclave parts if you already know what you need.
