NHTSA Complaint #11534996 — 2022 ACURA RDX

5 different occasions where the car enabled the emergency braking system for collision when there were no possibility of collision. This has occurred twice on the freeway, where all of a sudden, the vehicle slams down on the break, coming to a screeching halt. No vehicle or other object in front, side or back of vehicle that should cause this. The other instances happened on city roads and similar to the freeway instances. Hard braking for no reason, jolting me and passengers forward and causing vehicles behind me to not understand why we stopped randly and took so long to get going forward again as the emergency system doesn’t have a quick override.
