## Summary

The Office of Defects Investigation (ODI) received a petition on November 21, 2025, requesting a defect investigation to “determine whether the absence of a redundant mechanical wheel-fastener locking mechanism constitutes a safety-related defect in motor vehicles and motor-vehicle equipment” in the heavy-vehicle sector.
