NHTSA Complaint #11457020 — 2022 TESLA MODEL 3

When Adaptive Cruise Control or Autopilot is active the vehicle will brake suddenly, often with no apparent reason. On flat roads, highways, clear weather and even no traffic from time to time it will randomly regen brake for no reason. The only time this occurs and is duplicated regularly is when driving on a single lane highway. Whenever a 18 wheeler is passing on the opposite lane the vehicle always regen brake suddenly, regardless of the position of the passing 18 wheeler even when it's apparent that the passing 18 wheeler is staying in its lane. Sometimes if the 18 wheeler has a wide load the regen braking is much more aggressive and the forward collision will give a warning. These instances can be overridden by pressing down on the accelerator and that will override the automatic regen braking. The problem with that temporary fix is that when I know it's going to happen I'm prepared but when the times it happens randomly I might as well just never use adaptive cruise control or autopilot.
