NHTSA Complaint #11476416 — 2022 TESLA MODEL Y

While using cruise control (Traffic-Aware Cruise Control) on a recent road trip in our Tesla Model Y, the car unexpectedly and for no apparent reason, abruptly reduced speed. Our car is available for inspection upon request. Our safety and that of others was put at risk as a result of this unexpected reduction in speed while travelling on the highway. An accident could have occurred if cars travelling behind us did not similarly reduce speed to avoid a collision. The problem has occurred on a number of occasions where there was no apparent reason for the car to rapidly reduce speed. It has not been confirmed by a service center. The vehicle has not been inspected by the manufacturer or others. It is a known problem with the 2022 Model Ys based on a published inquiry by the NHTSA (ref: https://electrek.co/2022/06/03/tesla-respond-increase-phantom-braking-complaints/). There were no warning lamps or indicators prior to the unexpected braking event.
