NHTSA Complaint #11525423 — 2023 TESLA MODEL Y

This has been a consistent on-going issue with my brand new 2023 Tesla Model Y. While using Autopilots Traffic-Aware Cruise Control and the Autosteer feature the car will without warning begin braking. Each time is different in regards to severity of the breaking but it is typically like letting off the accelerator pedal which in a Tesla is comparable to significant breaking. Have taken two highway road trips and on both trips, the phantom breaking has occurred multiple times. Some of the incidents the car would go from 75MPH to 45MPH in a matter of seconds. From research done, this "Phantom Breaking" is a serious issue that Tesla says is due to software issues and not hardware issues. Our safety was put at risk because the person behind us might not be paying attention when cruising on open road, during daylight, etc and could rear-end our car. There have been no predictors or weather conditions that cause the braking. Usually, for us, has happened on sunny days on multi-lane highways with not a lot of traffic. Have taken car to dealer and they state it is a software issue. No warning signs that the breaking would happen and no objects or cars show up on the screen when it happens.
