NHTSA Complaint #11585056 — 2023 TESLA MODEL Y

When using Auto Pilot/Traffic Aware Adaptive Cruise Control at highway speeds (55 to 75mph), vehicle will on occasion, slam on the brakes and steer to the right for no apparent reason. When this has happened in the past, we would press on accelerator peddle, to quickly recover from the braking to prevent a rear end collision and continue down the road. This last time (April 12, 2024) however, pressing the accelerator peddle made no difference until Auto Pilot was disengaged. Fortunately we were in the right most lane and was able to pull off to the side of the road to prevent a rear end collision from a van that was behind us. There were no warnings or messages that were displayed to indicate what had cased the braking. I talked to my local Tesla service department approximately a year ago about this issue and said that Tesla is aware of the "Phantom Braking" problem, but were unsure if or when a fix would be in the works. We did capture the dash cam video of the last Phantom Braking incident, that shows a clear road, with no objects or shadows that may have triggered the event. The dash cam video is 38Mb in size, too large to upload.
