NHTSA Complaint #11477547 — 2022 TESLA MODEL 3

When driving on a 4 lane divided highway using adaptive cruise control at 70mph+, the emergency braking will suddenly activate, even when the road ahead is completely clear with no surrounding traffic. The car will suddenly brake, sometimes dropping 30mph or more off of speed, from 75 close to 40. Stepping on the gas pedal will abort this braking. If left alone, the car will stop braking and accelerate back to the original speed with no driver input. This will happen multiple times over 40 miles of highway driving. If it happened when being closely followed, the chance of being rear ended by the trailing car is high, though thankfully this has not occurred yet. The problem happens daily on commuting and has happened since taking ownership of the car on Jun 29, 2022 through today.
