Complaint Summary
FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Owner Narrative
Nature of Defect: While operating Full Self-Driving (FSD) at highway speeds, my vehicle exhibits involuntary lateral swerving â sudden, uncontrolled movement to the left and right without driver input. This behavior occurs repeatedly and unpredictably, posing a direct safety risk to the occupants of my vehicle and to other drivers. Tesla Service diagnosed the root cause as a failed FSD computer and recommended full replacement at a cost exceeding $3,000. Crashes or Injuries: None to date, though the behavior described above creates a significant risk of collision at highway speeds. Frequency: Recurring during FSD engagement at highway speeds. Additional Context: This defect was present during my vehicle's original warranty period. Tesla has been aware of this issue since my service visit and has not completed the repair. I have an active goodwill warranty request pending with Tesla that has gone unacknowledged for over two weeks. I am submitting this complaint because I believe this defect may affect other Tesla vehicles equipped with the same FSD hardware, and I want NHTSA to have a record of this failure mode.
