problem #3

Jul 052011

F-550 Superduty 7.3L

  • Automatic transmission
  • 265,000 miles


This is my work truck, if it doesn't run I can't work. Before the problem could be detected it run into thousands of dollars, including putting in new used motor, and right before blowing the second motor up the garage figured out there was debris in the gas. This resulted in a new fuel tank, multiple fuel lines to be replaced, fuel pump, and all the problems with a new used motor. All this resulting from some dumba** not having the common sense to know you don't paint the inside of a fuel tank.

Ford should have to pay for all repairs including loss of work. Since this has happened I have talked to several people and they have had the same experience and expense.

F-550 7.3L

  • Automatic transmission
  • 37,833 miles

I have 2 Ford F-550 trucks (2001 & 2003). Both trucks with very low mileage (37k, 56k miles). Both Diesel engines. Both have only had either Shell or Chevron fuel in them. As recently described by others in this forum, Ford Motor Company is blaming the delaminating on the fuel used in the trucks. My dealer (Westlie Ford, Camas, Washington) where I purchased these trucks cannot warranty the replacement tanks needed to remedy this problem. In fact, my dealer tried to gouge me on a price for a new tank after explaining my situation! This is beside the fact I have spent many thousands of dollars purchasing trucks and personal cars from this dealer. This is an epidemic for Ford Motor Company.

Surprisingly, I can find no aftermarket tank for this truck. Word has it Ford has "fixed"Ě the problem with the coating on the tank but, I can find no announcement from Ford Motor Company saying so. Any advice from other Ford Super Duty owners with this problem would be greatly appreciated!

(reported on)

F-550 Diesel

  • Automatic transmission
  • 46,000 miles

I have posted the following on Consumer Reports & with NHTSA, but I am looking for more support on this issue and I am trying to reach as many people as possible. This is a real concern for the hundreds of thousands of working men and women who own Ford diesel trucks made from 1998 - 2008. Ford has stated these are the years effected (I have it in writing). The repairs run in the thousands and Ford REFUSES to accept ANY responsibility. Please read on...

Mr. Alan Mulally, President Ford Motor Company 1 American Road Dearborn, MI 48126-2798

Dear Mr. Mulally,

I have had an ongoing issue that I feel is now at a point that you, and your colleagues that I can copied on this letter, should be aware of. And if Ford is the upstanding company I believed they were up until now, you will take some action on this issue.

I have had a fleet of solely Ford trucks used for my business for about 10 years now and have spent approximately $300,000. in vehicle purchase. I recognize that I am far from your largest customer, but you stand on the fact that you make the best works trucks for companies just like mine. This issue, along with the unbelievably bad customer service delivered, certainly makes a strong stance in just the opposite.

This issue is in reference to our 2003 Ford F-550 Diesel Dump Truck. The first documented occurrence of the problem of loss of power while on the road and running was back in 2005. The problem was finally properly diagnosed on September 13, 2007 by McCafferty Ford in Langhorne, Pennsylvania. The problem was that the lining of the fuel tank was flaking away and clogging the fuel lines, fuel pump and filter. Your reason for this happening was that 5% or more of biodiesel was used in the tank. After much research on my Assistants (Robin Beall) part, we have found that just about all of our fuel purchased for this vehicle was manufactured by either Exxon or Sunoco. Ms. Beall has been able to obtain statements, which Iíve enclosed, from both Exxon and Sunoco that determine undeniably that there is no chance ANY biodiesel was purchased from them. Beyond those statements, Sunoco has offered to not only test the fuel we saved from the tank, but will also run tests on every station we purchased from and go to their board and attorneys on our behalf with this issue. McCafferty Ford has also shown their support of us, just in order to keep us happy as their customer, has credited us back half of the repair costs. Which, as far as Iím concern, was not their responsibility to do and should be refunded to them by Ford. These tanks are obviously faulty for some reason other than the use of biodiesel in them.

Your customer service has spoken to us as if we were in the wrong and have been accusatory every step of the way through this and their last denial to us was a blatant lie. Gail Perez, Customer Care Specialist in the Escalated Department told us that McCafferty Ford stated that there was proof of the fact that there was 5% or more of bio diesel used and that was the sole basis of Fordís denial. No one at McCafferty made that statement to anyone. Nor is there any proof of such. And, McCafferty stated that they have addressed this same issue with Ford 6 or 7 times prior to our issue and that Ford has been ďvery uncooperativeĒ.

To sum things up, all we are asking from Ford is to take care of these repair costs, as they should. We will take this as far as it needs to go in order to be treated as any one of your customers, who have been as loyal to Ford as we have been, should be treated. My Assistant has done a great deal of leg work to substantiate the fact that no biodiesel was ever put in this truck and she has the ability to account for, support the make-up of, and obtain documentation on every drop of fuel ever put in this truck. Please donít force our hand to go to those lengths.

I would appreciate a prompt response to this issue.
