NHTSA Complaint #11559871 — 2023 TESLA MODEL 3

Ever since I purchased my 2023 Tesla model 3 I have periodically experienced a phenomenon widely referred to on the web as "phantom braking". Google it (though you probably already know about it). When it makes the biggest impression on me is when I am driving at over 50 MPH on an open highway and the car suddenly slows down, to the extent that it feels like someone is applying the brakes. Every time it happened in recent memory there were no cars in front of me for hundreds if not thousands of feet, which is why it's surprising because there has never been an apparent reason for the sudden deceleration. Instinctively, I look in the rear view mirror to see if anyone is behind me because if someone were relatively close behind me such a sudden slow down could, IMO, cause an accident - or at least alarm the other driver enough to slam on their brakes. Having read about phantom braking I believe that Tesla removed the traditional LIDAR (or equivalent) technology used by other car makers for adaptive speed control or a similar feature, and instead relies solely on cameras to make judgements. This decision, IMO, has led to a dangerous weakness in the reliability of Tesla's cruise control.
