2004 Jeep Wrangler Engine Problems

AT 91,500 MILES THE PCM FAILED FOR A SECOND TIME. I AM NOT CERTAIN WHEN THE FIRST FAILURE OCCURRED, BUT IT WAS SHOWN TO HAVE BEEN FLASHED PREVIOUSLY. THIS ISSUE SURFACED IN THE FORM OF A STALL OUT AT A LIGHT. WHEN ATTEMPTING TO ACCELERATE FROM AN IDLE POSITION THE ENGINE STALLED. AFTER PARKING THE VEHICLE, TURNING OVER THE ENGINE WHILE SIMULTANEOUSLY GIVING IT GAS, THE VEHICLE TURNED OVER. ACCORDING TO THREE DIFFERENT MECHANICS THIS IS A COMMON ISSUE AMONG '04 JEEP WRANGLERS THAT THEY HAVE ENCOUNTERED RECENTLY (12 YEARS AFTER MARKET AND 2 YEARS COMPLETELY OUT OF WARRANTY). NO ONE CAN FIND A REPLACEMENT PCM BECAUSE THEY ARE NO LONGER MANUFACTURED, AND IT WAS CHRYSLER'S RECOMMENDATION THAT CUSTOMERS EXPERIENCING THIS ISSUE GO TO A SCRAP YARD TO FIND A REPLACEMENT (LIKELY TO HAVE THE SAME ISSUE). AS A CUSTOMER I AM APPALLED THAT WE ARE AWARE OF THIS ISSUE AND THERE HAVE BEEN NO RECALLS. DRIVING DOWN THE HIGHWAY MY BATTERY CHARGED TO 20 VOLTS AND COULD HAVE EXPLODED.

WHILE TRYING TO USE THE AC ON MY 2004 JEEP WRANGLER , IT WAS OVERHEATING. I TOOK TO A DEALERSHIP SERVICE DEPT.THEY SAID IT WAS THE CLUTCH FAN.REPLACED UNDER WARRANTY AND TOLD ME IT WORKED FINE AFTER BEING TEST DRIVEN AND VERIFIED. I DROVE THE NEXT DAY,COULD NOT USE THE AIR BECAUSE AS SOON AS THE MOTOR WARMED UP IT OVERHEATED TO 260. I SHUT IT DOWN AND HAD IT TOWED BACK TO SAME DEALERSHIP(3RD TIME). TOLD THEM TO CHECK THERMOSTAT WATERPUMP ETCC.. EXPLAINED THAT I CAN'T EVEN DRIVE IT NOW FOR OVERHEATING. THREE AND HALF HOURS LATER THEY SAID IT IS A RADIATOR RESTRICTION AND I AM 32 ND ON A LIST BECAUSE APPARENTLY THERE HAS BEEN QUITE A PROBLEM WITH THE RADIATOR ON THE JEEP WRANGLER BUT NO RECALLS. THEY ALSO SAY THEY DON'T KNOW IF IT IS COVERED UNDER WARRANTY. I HAVE HAD IT LESS THAN A YEAR AND ONLY HAS 24000 MILES ON IT. THE WARRANTY IS 3/YR/36000 I BELIEVE. AM CHECKING ON HTIS. HAS ANYONE ELSE REPORTED THIS PROBLEM?
