My six-year-old Fiat Panda Cross, with full dealer service history, has only done 15,000 miles. At its MOT, I was told the propshaft centre bush was split and a new propshaft would cost £2,166 plus fitting, because Fiat does not supply the centre bush separately. Fiat customer services offered a goodwill gesture of £451. But surely a propshaft bush should not fail at this low mileage? What do you think?
