Over the years there hasn't been the best of service, usually within a day or two all my fault codes would be back, had a Cummins a while back and the fuel pump went out, i told them when i took the truck in what it was doing and i was pretty sure it was the fuel pump (warranty is 250,000.. and i had 253,000) and i went to the motel. The next day thet said it was ready and told me it was a leaking high pressure line, i never saw no leaks and there were no wrench marks on the lines. I left and got to st.Louis area and it fell on its face again. I got back thru Springfield and put it in again and went to motel and again told them it's the fuel pump. And again they said the next day it was fixed and said it was fuel regulator. And again the truck- fell on its face. So back i went and again told them fuel pump and went to motel.. and again they said it's ready and told me it was the fuel pickups I n the tanks that they were cracked.. and again i left and the truck fell on its face. So back i went.. and when i returned this time i again told them it's the fuel pump and vented some of my frustration to which i was told it was Cummins who had to authorize the work and they could only do what Cummins said. The next day when i returned they told me they replaced the fuel pump and the truck never had another issue... Cummins was not going to honor the warranty because by the time they replaced the pump i was at about 257,000 miles. Prime eventually got them to cover 75 percent of it. Also while at this dealership ...if you go out to smoke and the mechanics are out there taking a break i would often hear them complaining about their bosses and cursing the place out , which often made me think how much could they care about fixing my truck right?
