2023 Buick Enclave Problems

The driver side headlight was working and then it wasn't. A very costly expense to replace.

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.

Brakes squeak very loudly. This has been an issue since I purchased this new vehicle.

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.

Driver's seat belt cable going to floor on outside of seat broke, it is available for inspection. Seat belt is inoperative. I spoke with a dealer, but I am over on miles to be covered by warranty. The vehicle has not been inspected, and there were not any warning lamps or warning' I noticed when I tried to buckle up for ride home Friday evening 10/10/2025

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. Both driver side and passenger side retractors fail in the same manner. Passengers are not able to buckle themselves in. Will report to Freedom Motors who use SmartFloor vehicle seats in their products.

The contact owns a 2023 Buick Enclave. The contact stated while the vehicle was parked or while driving, the infotainment system failed to display as needed. The contact stated that the failure persisted, and a dealer was contacted. The vehicle was taken to the dealer to be diagnosed; however, the technician was unable to determine the cause of the failure. The contact stated that a software update was performed and an undisclosed part in the infotainment system was replaced. The manufacturer was notified of the failure several times but offered no assistance. The approximate failure mileage was 13,500.

The infotainment system locks up. Its like all features are on mute. I can't use phone, radio, contact onstarr or use navigation system I have a heart condition, when this freezes I have no way to reach help. The dealership has tried multiple fixes, they say they are just seller, GM is the manufacturer. GM no longer takes my calls. They have blocked all my numbers. There is no warning, it just stops working GM suggests I turn off vehicle, get out wait 20 minutes and the system should reset, I have tried to disconnect my phone from bluetooth and they seek each other out and reconnect. I live very rural, 20+ miles to anywhere. I have no way to get help

Anyone behind me could’ve hit the part and caused a wreck. We have told the dealer.
