The dealership is having major problems fixing my fuel pump. This time is the 3rd time in 2 months, 4th in a year, that my ML is in the shop for the fuel pump. The manager tells me each time that they put a new one in and this won't happen again. Well the first 2 times I believed them because I figured since I am not paying for it, it must really be fixed. Can someone give me any advise on what I might tell the dealership to fix since they obviously don't know what to do.
