Mazda has recalled 25,000 if its brand-new 2010 Mazda3 sedans to correct a wiring defect that could prevent the engine from starting.

In a defect notice filed with the National Highway Traffic Safety Administration, Mazda explains, "A clearance between the engine harness and the housing of the 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."  In an extreme situation, "The main fuse may blow out, causing the engine to stall and inability of restart, increasing the risk of a crash."

Mazda dealers will inspect affected vehicles, and "add a protector clip on the affected section of the harness.  If necessary, the harness will be repaired."  Dealers will begin contacting owners in early May, but those who wish to make their own repair arrangements may contact Mazda at 1(800) 222-5500.
