My Range Rover Evoque Auto Dynamic is suffering from a rumble noise from the back end (intermitently) , if it was an old car I would have said it sounds like the baffles were lose or the exhaust was catching somewhere on the body. It has been in three times now and the garage has not managed to bottom out the problem. Its an automatic so its not as though I were in the wrong gear. Anyone else having this problem? Its driving me mad!!!!!!!!!!
