NHTSA Complaint #11568357 — 2023 TESLA MODEL Y

While driving our new Tesla MYLR in heavy rain, with Traffic Aware Cruise Control (TACC) on, we experienced two Front Collision Warnings (FCWs) in quick succession, causing the car to massively reduce speed, causing a car behind us to nearly hit us. I believe this is called "phantom braking" in the common parlance. I believe this is also an issue with the wiper system. We were driving about 55mph on a two lane road. It was raining hard and the wipers were set to Auto. The wipers weren't working fast enough to clear the rain well, and adjusting the wipers in the Tesla are not easy to change, requiring hitting the end of the left stalk, then scrolling left or right with a scroll wheel while looking at the screen. There was not another car in front of us and TACC (but not autosteer) was on. All of a sudden a loud alarm sound blared, a FCW appeared on the display, and the car slowed to about 35 mph. The car behind us got very close to hitting us. This happened again about 5 minutes later. It scared the bejeezus out of us. This seems very dangerous!
