NHTSA Complaint #11510162 — 2021 TESLA MODEL Y

Multiple "phantom braking" events while using adaptive cruise control (no full self driving, just basic adaptive cruise). First time while going at interstate speed and crossing a bridge, vehicle saw a shadow on the road and slammed on the brakes thinking it was a vehicle. Obviously this is a startling and dangerous situation especially for vehicles behind you. This has also happened on the highway, flat terrain, roads were clear of any obstacles and it slams on the brakes thinking there is something in the road. Every time it does this, there appear to be shadows on the road (from street signs, light poles, trees, etc.). The sudden braking is of course bad, but there's also nothing in the vehicle that tells you why, no chime, it just hits the brakes. It still appears that cruise control is active, but it won't resume speed after an event like this until you turn cruise off and back on again. I know this isn't an isolated incident and it absolutely will cause a crash, if it hasn't already.
