2023 Buick Enclave Complaints

EXTERIOR LIGHTING — Filed 06/01/2026

Right-side LED headlight assembly failed at under 3 years and ~55,000 miles. Dealer states the sealed LED unit is non-serviceable and must be replaced as a complete assembly, quoted at ~$1,450. LED headlights are rated for tens of thousands of hours and are marketed to last the life of the vehicle; this failed at a small fraction of rated life. Other 2023 Enclave owners report the same right-side failure at similar low age/mileage, suggesting a recurring defect.

Headlight on right side failure - no light. AI shows a recall for this problem, but my vin was not listed. Notice also states 2022, 2023, and 2024 vehicles. It should be as car was only 2 years 10 months old with about 42000 miles. GM has the part now. Dealer inspected the car. Light had less then 750 hours on it; references say average light should last 20,000 hours. An obvious defect. Only noticed failure due to a neighbor seeing it. We drive mostly in the day due to age. Car is used only to go to work. Car has auto headlights, and they do not operate during daylight when we drive.

The SmartFloor rear passenger (driver side and passenger side) bucket seat seatbelt retractors do not release to allow a passenger to buckle the seat belt.

In Driver info center messages displayed are ESC “this is anti lock cracking system not working”. Steering assist reduced “this is lane departure steering assist not working” Parking brake. “not working” Also cruise control is not working Buick service tells me this has happened often enough in other vehicles that there is a repair bulletin on it. Also the initial cost to repair is $3000 + if this bulletin repair fixes the problem if not there would be more costs. This vehicle is within the 36 month bumper to bumper warranty period but has recently exceeded the 36000 mile warranty threshold. I have already paid for the initial part so it could be ordered.

UNKNOWN OR OTHER — Filed 01/02/2025

The car stalled and is stuck in park. It has electronic shift and if the engine doesn't run it has to be put into neutral manually. The Buick dealerships don't know how to do this and keep referring me to an obsolete video. One service representative suggested the manual lever is under the air filter housing but they cannot provide any information on this design, The car is stuck in a garage and cannot be towed. It is stuck in place.
