We purchased two 2004 F550 service trucks with the 6. 0. Unit #1 died on its' first service trip enroute to Seward, AK. It had to be towed in, and the diagnosis from our local ferd dealer was "water ingestion". They said that we must have refueled from a station with contaminated fuel. Funny, we filled the tank from that station (a high volume dealer in Girdwood, AK), and travelled more than 70 miles with fuel that ferd told us was 80% water! I wonder how combustion occurs with that fuel/water ratio? hmmmm...
They drained the tank, and declared it good to go. Two weeks later we bring it in for a knock. They claim it to be water-ingestion related, and we pay for damage to one injector. In the meantime they replace first the wastegate, and then the turbo under warranty. Hmmmm . . . :--)
We get the truck back, and the knock is still present. We bring it back, and the service writer first says that all 6. 0 liter engines sound like that, but only in the F550. The he says the sound is caused by low fuel (see a pattern here?). We bring the truck back to the shop, cut open the oil filter and find . . . TADA a filter full of metal. :{
Back to the ferd shop and a discussion with the service manager gets them to agree, yes there is a problem with the engine, and they will look at it. 3 holes are scored, and who knows what other damage exists? Now 6 weeks later, the engine is in pieces and the rocket scientists at the dealer are telling us the failure is due to the water ingestion (again?), and that the failure is not warrantable.
I might buy this if we knew nothing about diesels, but we happen to be the Cummins distributorship, and think they are full of shyte! The next bit of correspondence was a certified letter to the Ferd Customer Service Center in Michigan to try and get their attention before we turn it over to our attorneys. Time will tell.
And before I get flamed for buying ferd service trucks, Dodge still does not manufacture a truck that will take a service body and a crane. When they do, we will switch back.
And still I wait for my service truck with less than 2000 miles on it and a dead engine.
Cheers,
John
