What 18 owners told NHTSA about the 2023 Buick Enclave

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 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 headlights on our 2023 Buick Enclave do not provide nearly enough light at night. If you shine the lights up against a wall at night they seem bright but they do not seem to light up the area directly in front of the car. When driving on a road without streetlights at night I barely feel like my headlights are on. It’s so bad that I am concerned that if a person or an animal stepped out in front of my car I wouldn’t be able to see it in time to avoid it. I brought the car into the dealer today and they actually found that both headlights need to be raised 11-12 inches (they were completely shocked). This is very odd for a new car with only 5k miles. Unfortunately, raising the headlight did not add more light in front of the car at night. I think the issue is caused by the headlights not only being very small but also because they are very low on the car. Also, the headlights are below the grill and the running lights are on the hood. I believe this could be a design flaw that is also a safety hazard. A mechanic at the dealer also agreed with me that in general the lights are very dim. If you drive this model car at night on a road with no street lights I bet you will come to the same conclusion. Attached is the invoice from today that shows the headlights had to be raised. I told the dealer that they should pull another enclave off their lot and see if the issue is only present in my car or if the headlights on other enclaves need to be raised.

The vehicles low beams fail to properly illuminate the road, and create a significant blind spot in your vision. We bought a brand new 2023 Buick Enclave and noticed on the first night drive that the vehicles lighting has a very large blind spot where it fails to properly illuminate the road. When switching too high beams the blind spot is diminished but not eliminated. We immediately took the vehicle back to the dealer where they adjusted the lights. However, all that they accomplished was to move the blind spot more central to the vehicle. When traveling up or down hills the lighting problem changes. When traveling up a hill the blind spot is moved closer to the vehicle creating a larger hazard. Traveling down hill the lighting blind spot is moved a bit further out. This is truly a very big safety concern especially when around pedestrians at night as it is nearly impossible to seem them until the very last second. The lighting problem and safety is worse when traveling at higher speeds as you have no time react when things suddenly appear from a blind spot in the vehicles head lights. I have attached several pictures. Please get in contact with me if you have further questions. All attached photos have been taken with an iPhone 13 and have no visual enhancements.

As my husband was backing out of the garage to the East and turning the back end to the North so we could head forward out of our drive which is on a curve, the car accelerated and the brakes would not work. We went backwards down a very steep drive that goes to our machine shed and towards the bottom we were stopped by a tree. We could have suffered head trauma from the abrupt stop. If we had been backing out of the drive or a parking place, since we couldn’t stop, there could have been others involved and severe injuries. I called the sheriff’s office and they filed a report. Our insurance agent came out and took pictures. I called General Motors Buick and they opened a case. The car was towed to the body shop the dealership we bought it from uses. We noticed no warning lights or messages on the dash. After everyone left, I got on my computer and there were 2 diagnostic warning emails. One for the antilock brakes and the other for the StabiliTrac control systems,.
