NHTSA Complaint #11455830 — 2021 TESLA MODEL Y

Since receiving Tesla Model Y 2021.44.x software update, I've experienced phantom braking on the highway at least once every time I drive it using autopilot. This continues through the software currently installed 2022.4.x. The most common scenario is I'm in the second lane from the right, a car is entering the highway to enter the first lane from the right. Each car is in its own lane. My car sometimes brakes for no reason. On many occasions there are no cars anywhere near me, but the car breaks suddenly. Not a danger for others, but dangerous for the driver and upsetting for passengers. I now only engage autopilot when there are no cars close behind me and no one else is riding with me. I don't want to cause and be responsible for someone hitting me because my car braked for no good reason. I'd prefer regular old cruise control to this behavior.
