NHTSA Complaint #11495597 — 2020 TESLA MODEL Y

On a 900 mile drive, in one day, the “speed cruise control” would abruptly brake, as if it were seeing someone in front of us. It did this at a minimum 5 times. Never was there a car closer than 1/4 of a mile in front of us. Once it went from 78mph to 38mph in about 3 seconds, when there was a car about 3 car lengths behind us. On the return 900 mile drive it continued, at a lesser rate. I have reported this to Tesla, and they claim “my” car reports do not show anything out of the ordinary, and these errors are sometimes caused by…and they gave numerous reasons, such as speed limit data inaccuracies, etc. they also have determined that my car does not show any computer faults so there is nothing they can do. Unacceptable
