NHTSA Complaint #11469722 — 2020 CHRYSLER PACIFICA PLUG-IN HYBRID

Coming to a stop in traffic at an intersection, at around 10 mph, decelerating at around 0.1g, I did not get additional decel from the vehicle even with pushing the brake pedal to the floor. While coming to a stop I glanced in my rearview mirror and the vehicle in front of me abruptly came to a stop. During the reaction time delay from looking forward, recognizing the vehicle slowed and stepping on the brake harder, I received a FCW alert. I was already on brake pedal and after my reaction time elapsed I pushed hard on the brake pedal which sunk to the floor and gave no additional deceleration from the vehicle. This continued until the CIB/AEB built pressure and stopped the vehicle, which was about 0.25-0.5s later. I didn't hit the vehicle in front of me but the very disturbing part was that the vehicle was not responding or decelerating with driver request.
