Consumer Description

THERE IS A LOUD ROARING SOUND FROM UNDER THE HOOD. (SOUNDS LIKE A JET ENGINE.) VEHICLE DEALER SAYS THAT VEHICLE HAS A BAD COOLING FAN CLUTCH AND THAT THE RELATED COMPUTER SOFTWARE NEEDS REPROGRAMMING. THIS LOUD NOISE PROBLEM USED TO ONLY HAPPEN WHEN THE VEHICLE WAS COLD AND WOULD GO AWAY AFTER ABOUT A HALF MILE. VEHICLE APPEARS NOT TO SHIFT PROPERLY (AUTOMATIC TRANSMISSION) AND THE VEHICLE DOES NOT ACCELERATE WELL WHILE THIS LOUD SOUND IS PRESENT. SOMETIMES NOW THE PROBLEM OCCURS WHEN THE VEHICLE IS WARMED-UP. THE LOUD NOISE GOES AWAY AFTER A SHORT WHILE. *NM
