1 Automatic Emergency Braking problem

Failure Date: 09/05/2025

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) because we have no choice. One I pressed on gas & began moving over those plates, the Blazer stopped itself very abruptly & jerked my head forward & dash said I had to press on brake let off or something in order to move again - it was all very fast & I had a line of traffic behind me at 5:15 pm on a Friday (9/5/25). I'm very luck I did not get hit from behind & car behind me paid attention! that is the 3rd time my car has stopped suddenly; 2 times before it was when going up my very steep driveway so I had no one behind me & I wasn't as shook up - chevy needs to really look at this! it is a hazzard!!.
