Was told at 60,000 that cats had to be replaced.
Warrranty covered it. Now at 80,000 engine light came on. Dealer said air flow sensor, $250 part, had to be replaced and then said cats on one side over heated and inernally melted had to be replaced and material from cat can be sucked back into the engine and will damage engine if not replaced. This does not make sense to me. Car runs great. Just towed horse trailer 600 miles with no problems although once, after light came on, the engine missed twice. Has been fine since. Acceleration is fine and gas mileage is same. Has anyone else had this problem? I didn't think material from cat could be sucked back into engine, either.
