NHTSA Complaint #11533232 — 2022 BUICK ENVISION

The collision warning system allows you to choose whether you want beeps or just seat vibration. I always chose beeps. But the vehicle randomly switches out of this and goes to seat vibration without me doing anything. This has happened numerous times, and the first time contributed to me, backing into another vehicle. I asked, my service department to check it and of course nothing showed up because it happens randomly. Just yesterday as I was pulling into my garage I was waiting for it to beep and nothing. So I put it in park and checked the vehicle settings, and once again, it was not on beeps, although I had never taken it off. I’m disgusted with the safety feature that is not working.
