I was in stop and go traffic on the highway. The car in front of me started going and I did as well. At this point, I was at least 3 car lengths behind them. They braked fairly quickly and I was as well. When I was braking, the FCA emergency braking enabled super prematurely. The result of the emergency braking caused the vehicle behind me to rear end me. My car has since been repaired, however this is super disappointing on a brand new car with 500 miles.
