NHTSA Complaint #11710562 — 2010 MAZDA MAZDA3

NHTSA Complaint Narrative I am filing this complaint regarding a 2010 Mazda 3, VIN [XXX] . The vehicle experiences intermittent transmission control failures, including difficulty shifting out of first gear and warning indicators triggered by vibration. The transmission and transmission control module have already been replaced. The dealership has identified the wiring harness as the cause of the remaining failure. Mazda North American Operations has confirmed that the required wiring harness (BBM9-67-020H) is discontinued and unavailable. However, Mazda has not provided a written determination of whether the known wiring harness recall (engine wiring harness chafing affecting control systems) applies to this VIN, nor confirmed recall completion history. Mazda has advised the customer to seek aftermarket or salvage parts, but has not provided an approved repair remedy or goodwill assistance despite the issue affecting drivability and safety. I am requesting that NHTSA review whether Mazda has met its obligations regarding: 1.recall applicability determination by VIN, and 2.providing an adequate remedy when OEM repair parts are no longer available for a safety-related defect.
