What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
No airbag warning or alerts on dashboard. - I reported the accident to General Motors but no one yet assigned - GM case #: [XXX]. - No complete police report has been provided yet. Police provided link to Crash doc website with insurance info.
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,.
The transmission hesitates and momentarily loses propulsion when accelerating out a low speed right hand turn, creating a risk of a rear - end collision. It also shudders at low speeds when accelerating up hill, or when passing vehicles on the highway.
After purchasing this 2023 Buick Enclave July 26, 2026 two days later I heard a vibrating rattle coming from under the hood. I raised the hood and pinpointed the noise to be coming from under the motor cover. I could not remove that cover myself.
The contact stated that the vehicle went into LIMP Mode. Additionally, the computer system took control of the vehicle. The contact stated that the failure had occurred while driving in the center lane on a busy highway. The vehicle was driven to a safe location.
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.
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.
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.
