My ASX was bought at 3 months old and has been serviced at a Mitsubishi dealership each year since. The car is now three years and six months old. The petrol tank is leaking from the seam and has some rust around the area of the leak. The car has never been off-road. I am communicating with Mitsubishi UK and they have said that they may consider a goodwill payment after it has been examined by the local Mitsubishi dealership. Mitsubishi UK have already said, however, that they will not pay for any of the labour costs. Where do I stand and what percentage of the total cost of supplying and fitting a replacement tank (£750) would be reasonable? Surely, a leaking tank at just over three years old and 34,000 miles is not normal.
