Defect
MAZDA IS RECALLING 25,400 MY 2010 MAZDA3 VEHICLES. A CLEARANCE BETWEEN THE ENGINE HARNESS AND THE HOUSING OF STARTER MOTOR MAY BE INSUFFICIENT. DUE TO THIS, THE COVERING OF THE HARNESS MAY BE DAMAGED THROUGH VIBRATION DURING OPERATION POSSIBLY CAUSING A SHORT-CIRCUIT BETWEEN CERTAIN HARNESS WIRES AND THE STARTER HOUSING. A SHORT-CIRCUIT CAN RESULT IN ENGINE CONTROL MALFUNCTION AND/OR POOR SHIFT QUALITY.
Safety Risk
THE MAIN FUSE MAY BLOW OUT CAUSING THE ENGINE TO STALL AND INABILITY OF RESTART, INCREASING THE RISK OF A CRASH.
Remedy
DEALERS WILL HAVE THE ENGINE HARNESS INSPECT AND ADD A PROTECTOR CLIP ON THE AFFECTED SECTION OF THE HARNESS. IF NECESSARY, THE HARNESS WILL BE REPAIRED. THIS SERVICE WILL BE PERFORMED FREE OF CHARGE. THE RECALL IS EXPECTED TO BEGIN ON MAY 6, 2009. OWNERS MAY CONTACT MAZDA AT 1-800-222-5500.
