NHTSA Complaint #11473974 — 2021 TESLA MODEL Y

The vehicle was on cruise control (NOT auto-pilot). Driving on Freeway approximately 82 mph when the vehicle slowed to 60 mph instantly numerous time within my 160 mile drive. There were no vehicles in front or beside me. There were no obstacles in the roadway or on the side of the road. Sunny day with no clouds. There were no warnings lamps or messages that would indicate the car was going to brake. My safety was put at risk if there was another driver behind me, I could have been rear-ended. It Could also had been very dangerous if there was adverse weather. Tesla was not able to recreate the problem and never found any problems with the vehicle. This was not the first time we took the vehicle in for phantom braking. Tesla blamed the driver. I was also told by a tesla representative the the vehicle can brake unexpectedly by sensing a shadow on the road from a cloud. Apparently there is no way to disable this feature. The vehicle has been deemed unsafe to drive by our senior management as this is not the first time this has occurred and Tesla has not remedied the problem.
