20080130POWER TRAIN:AUTOMATIC TRANSMISSION
I HAD A MAJOR TRANSMISSION FAILURE DRIVING HOME FROM WORK. NO WARNING, NO NOISE, NO INDICATION WHAT SO EVER. VEHICLE HAD TO BE TOWED FROM HIGHWAY AT 2AM TO REPAIR SHOP. UPON INSPECTION BY THE REPAIR SHOP THEY FOUND THAT THE TRANSFER CASE FAILED AND CAUSED THE TRANSMISSION TO ULTIMATELY FAIL AS WELL....THE TRANSFER CASE PROBLEM WAS FIXED AND THE WARRANTY COMPANY ON COVERED MINIMAL COST....THE TRANSMISSION WAS FIXED AND THE WARRANTY COMPANY DID NOT COVER AND OF THE COST...LEAVING ME WITH A BILL OF OVER $1600.00!!!!! AFTER MISSING TWO FULL WEEKS OF WORK FOR THIS ISSUE I STILL HAD TO INCUR THE FULL COST OF THIS REPAIR. IT CLEARLY STATES IN THE WARRANTY CONTRACT THAT THESE REPAIRS SHOULD HAVE BEEN COVERED. PLEASE INFORM ME IF THERE ARE ANY RECALL ITEMS THAT COULD HAVE CAUSED THIS TRANSMISSION TO FAIL. *TR
