NHTSA Complaint #11448306 — 2021 TESLA MODEL Y

I was driving on the 7 mile bridge in the Florida Keys with the Adaptive cruise control set to 58 mph. There was no traffic in my lane for about a mile ahead of me. As an oncoming Semi approached me, remaining in his lane, my car applied emergency braking. I had to immediately add throttle to avoid a collision with the truck behind me. This “ Phantom braking “ has occurred on multiple occasions to me. There is no way to engage cruise control without the adaptive feature which uses cameras instead of radar on these new Teslas. I did not have this problem on my 2018 Tesla that did use radar.
