DATING BACK TO 2 YEARS AGO, I HAD A JEEP DEALER CHECK THE EXHAUST SYSTEM FOR A "FLUTTERY" NOISE, WHICH I THOUGHT SOUNDED LIKE AN EXHAUST LEAK. IT WAS CHECKED AND THE CATALYTIC CONVERTER WAS REPLACED UNDER EMISSIONS WARRANTY. FOUR MONTHS LATER I TOOK THE JEEP BACK DUE THE PROBLEM NEVER HAVING BEEN FIXED. THE DEALER CHECKED IT OUT AND TIGHTENED THE EXHAUST CLAMPS. THIS MADE NO DIFFERENCE, BUT I WAS TOLD EVERYTHING IS NORMAL AND TOOK THE FLUTTERY NOISE AS THE "NORMAL" ENGINE/EXHAUST NOISE JEEP MAKES. RECENTLY I TOOK MY JEEP TO HAVE VARIOUS FLUID LEAKS REPAIRED ($500 WORTH) AT MY COST, AT WHICH TIME THE DEALER NOTIFIED ME THAT MY EXHAUST MANIFOLD IS CRACKED AND WOULD COST $1,000 (EST.) TO REPAIR. I WAS TOLD THAT NO WARRANTY WOULD COVER IT AND SINCE I HAD CLOSE TO 90,000 MILES ON THE VEHICLE I DIDN'T HAVE OPTIONS TO HAVE JEEP TAKE CARE OF THE PROBLEM. THE NOISE I HAVE BEEN HEARING ALL ALONG HAS BEEN A CRACKED MANIFOLD, SO THE PROBLEM FIRST MANIFESTED ITSELF WHEN MY VEHICLE HAD 52,000 MILES. THIS JUST DOES NOT SEEM WHAT ONE SHOULD EXPECT FROM A VEHICLE AT 52,000 MILES. I AM LOOKING TO FIND OUT IF THERE HAVE BEEN MANY OTHER SIMILAR PROBLEMS AND WHAT MY RECOURSE OPTIONS ARE. THANKS FOR YOUR HELP!
