NHTSA Complaint #11449873 — 2021 TESLA MODEL Y

While on a 475 mile road trip, my vehicles emergency brake system was activated while using cruise control on more than one occasion with no visible hazard ahead of me. This caused my car to brake at speeds upward of 70 miles per hour on two lanes highways, leaving me to fear that any car behind me could easily rear end me and harm me or my children who were in the backseat. On another occasion during this same trip, the weather began to turn. Snow began to fall heavily leading to poor road conditions. My model y activated corrective steering twice at speeds of 10-20 miles/hr, both times attempting to swerve my car into the lane next to me occupied by a semi truck. These issues are unacceptable and need correcting as they pose a threat to passenger safety.
