was on my way to the track on sunday, doing about 75-80 on the expressway when the car starts vibrating like crazy. thought it was a flat so i pull over, no flats. look under the hood and see that the engine is seriously leaning to the left! Both of the studs that connect the engine to the left side motor mount had broken. so i had it towed to the dealer and they are fixing it under warrenty. anybody else have this happen to them??
