ON CERTAIN PASSENGER VEHICLES, THE MAIN UNDER HOOD ELECTRICAL WIRING HARNESS MAY HAVE INSUFFICIENT CLEARANCE BETWEEN THE ENGINE CONTROL HARNESS AND THE EXHAUST HEAT SHIELD. AS A RESULT, THE HARNESS COULD COME IN CONTACT WITH THE HEAT SHIELD, WHICH COULD RESULT IN MELTING OF THE HARNESS INSULATION.
Consequence & remedy
Consequence: THE MELTING OF THE HARNESS INSULATION COULD RESULT IN GROUNDING OF THE CRANK ANGLE SENSOR WIRING, CAUSING THE ENGINE TO RUN ERRATICALLY OR STOP SUDDENLY, INCREASING THE RISK OF A CRASH.
Remedy: DEALERS WILL INSPECT THE HARNESS FOR DAMAGE AND, IF NONE IS EVIDENT, WILL TIE THE HARNESS BACK TO PREVENT THE HARNESS FROM EVER COMING INTO CONTACT WITH THE HEAT SHIELD. ANY HARNESS THAT SHOWS EVIDENCE OF DAMAGE WILL BE REPAIRED AS NECESSARY AND THEN TIED BACK TO PREVENT FUTURE DAMAGE. OWNER NOTIFICATION BEGAN NOVEMBER 13, 2002. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT MITSUBISHI CARIBBEAN AT 1-787-251-8715.
