NHTSA Complaint #11463556 — 2022 TESLA MODEL S

I have used the self driving feature of my 2022 Tesla Model S on several highway trips, most recently a round trip between Seattle and Palm Springs. The following problems with the Tesla self driving feature were noted. (My car has only the basic self driving feature, not the full self driving upgrade) 1. Random “phantom braking” where the car, without apparent reason, suddenly braked. 2. On several occasions the car abruptly swerved off toward an off ramp. I think this occurred when the white line marking the side of the road was interrupted by the off ramp where there was no painted line. 3. On several occasions when the turn signal was activated in order to change lines the car started to move over into the adjacent lane but abruptly swerved back to the original lane. I was able to maintain control but it was a frightening event. Due to the unpredictable nature of these events I greatly reduced my use of the fsd feature.
