NHTSA Complaint #11478811 — 2021 TESLA MODEL Y

On October 12th, 2021 my vehicle had multiple instances of phantom braking that occurred on highway 10 in California while traveling Eastbound with autopilot engaged. This was a trip in excess of 400 miles. Two of these instances occurred as my vehicle approached rainwater washes where metal barriers appear on both sides of the road ( see 33°38'10.5"N 115°05'01.6"W for an example ). The third instance occurred when a truck in the slow lane began drifting towards my lane slightly. In each of these three instances the car did a heavy braking at which time I quickly disengaged the autopilot by tapping the brake and speeding back up. Thankfully no accident but these three occurrence were scary. I reported phantom braking into the voice command database of the vehicle after each occurrence. According to a tesla representative these are saved.
