Consumer Description

FOR THE SECOND TIME, IN INTERSTATE HIGH SPEED TRAFFIC (70MPH) THE CAR WITHOUT WARNING DOWNSHIFTED. A THUNDEROUS CLUNK IS ACCOMPANIED BY THE CAR LURCHING AS IT DEACCELERATES THEN ALMOST IMMEDIATELY RESUMES SPEED. BUT INSTEAD OF THE ENGINE BEING AT 1800 RPM ITS CLOSER TO TWICE THAT. IN BOTH CASES THE DRIVER BEHIND ME THOUGHT THAT I BRAKED INTENTIONALLY AND NEARLY REAR ENDED ME. THE CAR IS THEN STUCK IN A LOWER GEAR AND IS DRIVEABLE WITH EXTREMELY POOR RESPONSE. I HAD IT TOWED ONCE AT THE DEALER'S REQUEST AND THE LAST TIME I WAS ABLE TO DRIVE IT TO A DIFFERENT NEARBY DEALER TO DEMONSTRATE THAT UNQUESTIONABLY THE CAR WAS STUCK IN ONE GEAR. IT IS AN AUTOMATIC. I'M SKEPTICAL THAT EITHER DEALER HAS ANY CLUE TO WHAT IS WRONG. I WON'T LET ANYONE IN THE FAMILY BESIDES ME DRIVE THE VEHICLE AS I'M AFRAID FOR THEIR SAFETY. IT HAS LESS THAN 7000 MILES AND IS 8 MONTHS OLD. THE FIRST EVENT WAS OVER 1000 MILES AGO AND ABOUT 5 WEEKS EARLIER. *TR
