2022 BUICK ENVISION Forward Collision Avoidance Automatic Emergency Braking Problems

Car applied emergency braking when it should not have (and could have caused an accident)! Details: Driving approx 20 mph in traffic on highway in Houston. Approx 3-4 car lengths behind vehicle in front of me. There were cars to the left and right of us, .. they were staying within their lanes. For no apparent reason, the automatic braking system applied the brakes. The four of us in the car were jerked forward. Luckily the driver behind us was not tail-gating, or we would have been rear-ended. Note: This was a National rental car I had in Houston this past weekend. Nonetheless, I want to report this as this apparent software and/or sensor bug seems like a major safety risk to me. I tried to find a way to report this to Buick too, but they don't make it easy to find a way to report a safety complaint...
