The front sensor is calibrated wrong. It slams my brakes on road if a shadow is in road, bridges, vehicles parked on side of road, and sometimes if another semi passes me it slams the breaks on. It happens if its just raining out not so much winter because snow and ice blocks the sensor. This has also almost caused accidents as well.

I was north of Louisville Kentucky on [XXX] traveling at 65 mph and I was in the middle lane and the collision lights came on and the truck abruptly started stopping. Luckily no one was on my right side. I made it to the shoulder of the road. Thank God I wasn’t rear ended by anyone and there were three lanes of traffic.
