NHTSA Complaint #11470936 — 2021 TESLA MODEL Y

Driving on major interstates across Idaho, Wyoming, and Utah, there were several instances of so-called “phantom braking” — while using Adaptive Cruise Control, with no other cars or obstacles in front, the brakes were rapidly applied, decelerating the car from roughly 75 MPH down to around 60 before I could manually press the accelerator pedal to override the behavior. Not only is this dangerous for myself, but could easily cause an accident if people are following closely at highway speeds. If Tesla’s camera-only system (as opposed to radar) can’t do the job, they should at least provide an option for a non-adaptive cruise toggle that would hopefully work around the issue.
