NHTSA Complaint #11534870 — 2019 TESLA MODEL 3

I have a 2019 Model 3 and yesterday, while making a left turn and applying pressure to the brake, receiving feedback from the brake, my car lurched forward for about half a second. I thought I may have been rear ended, but no one was behind me. This has happened on the freeway before as well. I'll be accelerating at a totally even place and BAM, I'll jolt forward out of nowhere. On the rare occasions that I use the car's "autopilot" feature, I will also encounter phantom braking, but that's easily avoided by not using the feature, which I haven't since first encountering the problem. I haven't suffered any damages from this, but if my car is able to do this, that's extremely alarming. What if this tripped while I was parking?
