The Automatic Emergency Braking problem

Auto braking system went off when I was at stop light & began to move forward (was 2nd in line of cars) and I accelerated. On the roadway, there are construction 'steel plates' laying on the ground in the area that all cars must drive over (I have driven over them in my same Blazer before)   Read details...

The Warnings problem

The first incident started on 08/16/2024, 2 days after buying the vehicle used from dealership. I started getting notifications stating "service-front camera not available" and sure enough, I no longer had a front camera, which then means I no longer have front collision alerts.   Read details...

The Crash Imminent Braking problem

The contact owns a 2021 Chevrolet Blazer. The contact stated that while stopped at a railroad track, the vehicle independently stopped and went into crash mode while on the railroad tracks upon acceleration. The contact shifted the vehicle into reverse and then into park.   Read details...
