NHTSA Complaint #11457532 — 2018 TESLA MODEL S

On 3/15/2022, I was driving on I405 with auto-pilot engaged. My car (Tesla Model S) suddenly braked hard for no apparent reason. I had to disengage auto-pilot and quickly accelerate to avoid the car behind me from rear ending my car. Fortunately, I remembered to save the event recorded on Tesla cameras. Take a look at 2022-03-15_12-24/2022-03-15_12-24-53-back.mp4 file around 46 sec ~ 51 sec within the file. You will notice that the car suddenly braked around that time causing the car behind to nearly rear-end my car. If you watch recording from the side+front cameras around the same timeframe, you will notice that there was nothing in the front or on the sides that warranted sudden braking. Those files are 2022-03-15_12-24-53-front.mp4, 2022-03-15_12-24-53-left_repeater.mp4 and 2022-03-15_12-24-53-right_repeater.mp4 The Tesla app does not allow me to create a new service request for this issue because I have another request open for a minor and unrelated issue. Therefore, I have not been able to report this to Tesla. I will do so after 3/22 when the current request is resolved. Note your site does not allow uploading video files therefore I could not attach them to this report. I can make them available if you need them.
