NHTSA Complaint #11455661 — 2022 TESLA MODEL 3

Just purchased a new Tesla Model 3 (long range) yesterday. On the drive home, I engaged the cruise control after the car reached its required calibration distance of 50 miles. Occasionally, but without warning, the car would automatically apply the brakes with no car or other visible obstruction ahead of me on a long straight road. The brakes were applied so firmly that the car would have come to a complete stop within 200-300 feet if I had not engaged the gas pedal to stop the braking action. The suddenness of the braking forced the car behind be (my wife, who was following at a safe distance) to aggressively brake in order not to rear-end me. This happened 3-4 more times during the 120-mile drive home, so I finally disengaged the cruise control and "manually" controlled the accelerator by foot for the last 20 miles of driving, without further incident.
