Recall 02V1000013,885 vehicles

Problem: 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.
Risk: 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.
Fix: 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 MAY 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 AT 1-800-222-0037.

MY WIFE WAS DRIVING ON THE INTERSTATE WHEN THE TRANSMISSION FAILED AND WOULD NO LONGER PROPEL THE VEHICLE. I HAVE RESEARCHED THE PROBLEM AND MULTIPLE PEOPLE HAVE HAD THE SAME PROBLEM. I DON'T UNDERSTAND WHY NO RECALL HAS BEEN MADE. THIS IS A VERY HAZARDOUS ISSUE, ESPECIALLY IF YOU ARE TRAVELING ON AN INTERSTATE. SHE HAD TO COAST THE CAR OVER AND WAS RAPIDLY LOOSING SPEED, A VERY DANGEROUS SITUATION. THE PROBLEM IS A FAULTY PART IN THE TRANSMISSION CALLED A WAVE SPRING. IN EVERY F4A51 MITSUBISHI TRANSMISSION, THIS HAS BEEN AN ISSUE. THE WAVE SPRING BREAKS, BYPASSES THE FILTER, ENTERS THE PUMP GEARS AND BREAKS THE PUMP, ENDING IN TRANSMISSION FAILURE. IT IS A COSTLY REPAIR, $1800-$2000. IT IS…
