NHTSA Complaint #11450176 — 2018 TESLA MODEL 3

When the vehicle is in autopilot, it sometimes (once every couple of months or so) will suddenly engage automatic braking as though there is an obstacle detected in front of the vehicle. In nearly every instance, this has happened at one particular location on an interstate where an overpass casts a shadow on the interstate on which the vehicle is located. The problem seems to be that the vehicle senses an object in front of it and the collision avoidance system is engaged; however, that "object" is only a shadow. This has happened in a few other locations (not simply this where this one overpass is).
