NHTSA Complaint #11459469 — 2022 TESLA MODEL Y

My Tesla Model Y has an ongoing problem with unexpected and unnecessary automatic braking when there is no apparent reason for the system to act--there is never anything in the lane ahead to brake for. The car just brakes and rapidly slows down at highway speeds. This has not resulted in a collision yet, but I'm fairly certain that it could result in a rear end collision if the driver following my car is "tailgating." At the very least, this is likely annoying to drivers following my car when this occurs. This is a very unnerving experience and should be fixed by the manufacturer. Tesla owner forums refer to this phenomenon as "phantom braking." This only seems to occur when I'm using the adaptive cruise control and/or the autopilot features on the vehicle.I have noticed this happening often on two lane and four lane highways, but not on freeways to date. I recall this happening every time I drive for any distance using the cruise control and/or autopilot. When I turn off the cruise control and/or auto pilot, it stops.
