Open the full vehicle complaint log (all categories)I was driving my car on the freeway on cruise control, when there was a sudden/automatic violent break of 65 MPH to 0 MPH. There was no car in front of me, and there was nothing above my car (no direction sign, no bridge, no FASTRAK billboard, nothing). This was a "phantom break" and it was violent and sudden. Tesla needs to fix this!
When using Autopilot / TAC cruise control the vehicle sometimes applies the brakes for no reason.
Complaints are unverified consumer reports submitted to NHTSA. A high complaint count may reflect vehicle popularity, not defect severity. Data sourced from NHTSA public records.
