NHTSA Complaint #11420182 — 2020 JEEP GLADIATOR

I was driving, accelerating into heavy traffic, and just about to go under an overpass (sunny day), when the Forward Collision System activated and hard-braked me to a stop, nearly causing an accident with the vehicle behind me. Although there was a car in front of me, it was not close and there was no danger of a collision (it was accelerating). Worse, no warnings came from the system until it started braking. This has happened several times, always in heavy traffic, and always on a underpass or lower bridge deck. I'm going to have to turn this system off, because I don't want to get rear-ended. My FCS is on the medium setting.
