NHTSA Complaint #10443964 — 1997 JEEP GRAND CHEROKEE

ENGINE STALLS EITHER AT SPEED OR DURING IDLE AFTER 20 MINUTES. WILL CONTINUE TO STALL FOR ABOUT 4 MINUTES, SOMETIMES VERY HARD TO START DURING THIS TIME. THEN VEHICLE WILL RUN FINE WITH NO PROBLEMS FOR SEVERAL HOURS. THE NEXT DAY, OR AFTER VEHICLE HAS BEEN SITTING FOR SEVERAL HOURS, THE PROCESS WILL START AGAIN. EVERY DAY IT WILL STALL AFTER ABOUT 20 MINUTES - SOMETIMES WHILE TURNING, WHICH WILL CAUSE A TOTAL LOSS OF STEERING ABILITY, OR WHILE ON THE FREEWAY, OR WHILE AT A RED LIGHT OR INTERSECTION. I NARROWLY ESCAPED AN ACCIDENT WHEN IT STALLED AND A BIG RIG ALMOST SLAMMED INTO ME. I HAVE BEEN STRANDED IN THE MIDDLE OF A BUSY INTERSECTION MULTIPLE TIMES BECAUSE OF THIS. WHEN THE CAR STALLS, SOMETIMES IT RUNS VERY ROUGH AND BACKFIRES, WHICH CAUSED THE CATALYTIC CONVERTER TO BLOW OUT. NOW THE CATALYTIC CONVERTER RATTLES AND CAUSED MY EMISSIONS TEST TO FAIL WITH HIGH NO(PPM) OUTPUT. I'M GOING TO NEED TO CHANGE THE PCM AND THE CATALYTIC CONVERTER TO FIX THIS, BUT THIS WAS COVERED UNDER A RECALL FOR 1996 VEHICLES WITH THIS SAME PROBLEM. JEEP ISSUED AN EMISSIONS RECALL IN LATE 2006 TO UPDATE THE POWERTRAIN CONTROL MODULE (PCM) SOFTWARE ON CERTAIN 1996 VEHICLES. AS PART OF THE RECALL, THE CATALYTIC CONVERTER WILL ALSO BE INSPECTED FOR DAMAGE AND REPLACED AS NECESSARY. 1997 VEHICLES EXPERIENCING THE EXACT SAME PROBLEM WERE NOT INCLUDED IN THIS RECALL FOR SOME REASON. PLEASE INCLUDE THE 1997 VEHICLES IN THIS RECALL. *TR
