NHTSA Complaint #11450535 — 2021 TESLA MODEL Y

I commonly will experience phantom breaking driving on two-lane roads, particlualy when meeting oncoming traffic. This occurs most commonly at the crest of a hill or when meeting trucks. It occurs nearly 100% of the time when meeting trucks at the crest of a hill. There are also random occurrences on flat roads with no other vehicles and no shadows or bridges. It also occurs on bridges and occasionally with shadows. Performance has been better on four lane roads with more traffic. It's as if the system needs to have other traffic to gauge itself. With no traffic on four lane roads, phantom braking will rarely occur. There is no single date of this occurrence. It happens ALL THE TIME.
