πWhy This Matters
Airbags are a fundamental safety feature, and any malfunction can severely impact the protection they offer during an accident. The recalls highlight potential failures in both frontal and curtain airbags, with improper calibration and electrical terminal compatibility being key issues. If these airbags fail to deploy when needed, it could lead to increased injuries or fatalities in crashes, making this a critical area of concern for current and prospective owners alike.

Power Liftgate was functioning erratically and now it won't open at all. Currently there is no way to manually open the liftgate or access the rear of the vehicle without climbing through the vehicle to get to the trunk area. Electrical switches on inside, exterior of vehicle nor the keyfob will open the liftgate. Previously the liftgate opened on its own at unintended times and now it has simply quit working. Safety issue was when it was opening while driving. It is not currently doing this since it won't work anymore. Complete Failure happened around 54K miles.

Catalytic converter was defective in October 2022. Had to wait to get part in. Vehicle taken to dealer for repair in December 2022/ Told that the second catalytic converter needed to be repaired. I stated that I was not aware that cars had two catalytic converters. Parts were ordered and replaced. Engine light came back on-again October 15, 2024. Portable CO detector in car was beeping when engine around time engine light came on. Not covered by warranty or insurance. A new car with 55, 000 miles to date should not have these issues.

The rear switch on our tailgate has failed and it allows the tailgate to open/close randomly on its own while the vehicle is locked even. I contacted Buick about the problem and they said didnβt care, but this can happen while the vehicle is moving down the road as well as when parked. Itβs not necessarily a typical safety issue that are normally recalled for, but it does pose significant safety issues if you want your car to be locked and you come back from the store and itβs not and people are free to break it or if it were to happen while moving. We had this happen on our car at around 38,000 miles. From reading other Buick forums to try and figure out what the cause is, it sounds like itβs a somewhat common occurrence. Itβs alarming that it can open while the vehicle is locked.

When driving my car down the street today, it abruptly stopped in the middle of the street and and engine locked up. I could not shift gears. I could not put my car in neutral. I was literally stuck in the middle of the street with a vehicle that gave me no warning of malfunctioning. This is the 3rd transmission that I have had in this car. It is a 2021 Buick Enclave with just over 12,000 miles.
