NHTSA Complaint #11519720 — 2020 TESLA MODEL 3

While driving in FSD, autosteer, traffic aware cruise control, and with all turned off, I have experienced 5-10 episodes of “phantom braking” on the highway at high speeds over the past 48 hours. I have driven in 4 states total so far; in sunny, cloudy, straight road ahead conditions, sometimes with cars around and sometimes on totally empty stretches of road. The first episode took my car from 80mph to 60mph extremely suddenly, with no warning, lurching me and the things in my car forward. I was shocked as I was unfamiliar with this issue. Luckily the car behind me at the time was about 1/8 mile away. However, this could have very easily caused someone to rear end me. This repeated over and over all day yesterday, sometimes the braking less severe than others. Now if using cruise control I need to hold my foot over the accelerator instead of the brake, which feels wrong and also unsafe, but it’s terrifying and I disengage cruise control if anyone gets too close behind me to be safe.
