The National Highway Traffic Safety Administration (NHTSA) has opened a defect investigation affecting an estimated 10,000 Michelin XZA tires.

NHTSA's Office of Defects Investigation (ODI) has identified 6 Vehicle Owner Questionnaires (VOQ) alleging steer tire failure involving the subject tires. Five of these reports are from a single fleet with each indicating a loss of vehicle control and a subsequent crash.

A Police Accident Report (PAR) related to one of the crashes was also submitted to ODI. In this report, the investigating police officer suspected that a tire defect was the cause of the crash. All reports received involve truck/tractor & trailers configured as auto haulers. Multiple vehicle OEMs and trucking fleets are involved.

ODI has opened a Preliminary Evaluation to gather information and assess the frequency, scope, and potential consequences of the alleged safety defect.
