NHTSA Complaint #11516060 — 2021 TESLA MODEL 3

there were 2 phantom braking incidents today traveling between pasadena and berkeley onhighway 5. it was getting cloudy. the first incident occurred just after i passed under an overpass, and thought it might have been due to the lighting. the braking was mild . there were other cars passing me on the left. i had the cruise control set to around 74mph. i probably slowed to 65mph the second phantom braking incident was about an hour later, and it was HARD. fortunately the cars behind me were far enough away. the cruise control was also set around 74mph. interestingly, no audio alerts were issued with either incident. normally, when driving without cruise control, the car will issue audio alerts (loud, urgent beeping) if a car gets too close. in both of my cases, there were no cars in front of me as i was in the slow lane.
