NHTSA Complaint #11532650 — 2022 TESLA MODEL 3

I was driving my 2022 Tesla Model 3 Long Range. This car does NOT have Autopilot (because we do not trust that technology). We were traveling eastbound on I-8 just east of Exit 61 from San Diego to Arizona on Sunday July 16 at about 2:30pm. The weather conditions were not an issue; it was sunny and warm. I was in the left lane doing 77mph with the Cruise Control on. I had passed a vehicle in the right lane and it was now maybe 500 feet behind us, still in the right lane. Suddenly, the Tesla Model 3 braked hard for no reason. The car braked so hard that the tires were starting to squeal. We were well inside the lane (had not drifted to either side). There were no obstacles in front of us. There was no discoloration on the highway from any repair or car fire. The road was completely visible. The car's speed had dropped from 77mph to about 57mph before I could press on the gas to resume normal driving. Had there been a car behind us, it's possible we could've been hit from behind. The car in the right lane did wind up passing us and I'm pretty sure they thought our driving was dangerous -- borderline insane. There were no warning sounds, no alerts on the monitor. It was completely random, completely sudden and completely dangerous. The car did this 2 more times before I disengaged the cruise control for the rest of the trip. I do not have a dashcam recording of this incident, but I do have one of a similar behavior from the car a few days earlier on July 13. It's hard to tell from the video exactly where it happens.
