NHTSA Complaint #11451517 — 2021 TESLA MODEL 3

I received delivery of a Tesla Model 3 Long Range vehicle on Oct 25, 2021. On nearly every occasion that I use the “autopilot” cruise control feature, one or more phantom braking events occur. When this happens, my vehicle decelerates rapidly and without warning with enough force to thrust my head and upper torso forward. In all cases, there is nothing in the road and no perceivable road condition to warrant this behavior. Fortunately, no one has been close behind me yet when this has occurred since it would surely result in a rear end collision. There appears to be no consistent pattern: it happens on sunny and cloudy days; day and night; highway and surface streets. I have gotten into the habit of leaving my foot resting gently on the accelerator when in autopilot mode in order to react quickly to these events and hopefully avoid a collision. On Dec 17, 2021 I mentioned this issue during a service appointment at my local Tesla dealership. The response was that this was a common and known problem with Model 3’s and would be hopefully worked out in future software updates as the system “learns”. Four software updates later, the problem has not been resolved and in fact seems to be occurring more frequently. I believe this phantom braking problem is a serious safety issue that Tesla should immediately address.
