NHTSA Complaint #10131577 — 1999 JEEP GRAND CHEROKEE

ENGINE DIES AT ANY SPEED WITHOUT WARNING AND WITHOUT ILLUMINATING THE CHECK ENGINE LIGHT. NO ERROR CODES ARE STORED. IT ACTS AS IF SOMEONE JUST TURNED THE IGNITION KEY TO OFF AND ALL OF THE GAUGES ON THE INSTRUMENT PANEL ARE ZEROED TO THE LEFT BUT EVERYTHING ELSE ELECTRICAL STILL WORKS, STARTER, POWER WINDOWS, RADIO, HORN, LIGHTS, POWER-SEATS, ETC. ETC.. THIS TENDS TO HAPPEN MORE OFTEN ON WARM DAYS, OVER 88 DEGREES F AND SEEMS TO BE A SHUTDOWN OF THE PCM WHICH CONTROLS THE FUEL PUMP, FUEL INJECTORS AND THE IGNITION SYSTEM. WHEN THE PCM SHUTS DOWN, IT DROPS OUTPUT TO PCM'S COMPUTER BUS CALLED THE CCD. I CHANGED THE PARTS THAT THE DEALER WANTED TO CHANGE LIKE THE FUEL PUMP, CRANK AND CAM SENSORS AND CLEANED A HOST OF OTHER SENSORS BUT THE PROBLEM REMAINS. THE PROBLEM IS WITH THE PCM. THE DEALER DENIES COVERAGE BECAUSE THE MILEAGE HAS JUST CREPT OVER 80,000 MILES ALTHOUGH I BEGAN DISCUSSING IT WITH THEM AND BUYING PARTS FROM THEM BACK ON MARCH 5, 2005. THIS IS AN EXTREMELY DANGEROUS CONDITION THAT WARRANTS THE PCM, P/N RL044427AC THROUGH AJ, ON THE 1999 JEEP GRAND CHEROKEE BE RECALLED. *NM
