2003 Ford F-250 Super Duty Problems

Engine -- Verified

The cooler for the EGR valve can leak coolant internally, which causes white smoke to come from the tail pipe. Hot exhaust gases are cooled by the EGR cooler before being circled back into the engine.

Engine -- Verified

The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.

Engine -- Verified

There is a technical service bulletin for the V8 engines regarding a possible problem with the spark plug being ejected from the cylinder head, damaging the threads in the spark plug hole. If the vehicle is under warranty, cylinder head replacement is recommended. If the vehicle is out of warranty, Ford authorized the use of a specific thread insert to repair the head.

Exhaust & Emissions -- Verified

Delamination of the diesel fuel tank can occur resulting in a loss of power due to debris clogging the fuel filters. In some cases the fuel injection pump and/or fuel injectors have also been damaged. Ford has issued a service bulletin (#19728) addressing this concern.

Engine -- Verified

A severe lack of power may develop because the hose from the turbocharger to the intake manifold can come loose, resulting in loss of boost pressure to the engine.

2003 Ford F-250 Super Duty Reviews

For the most part we really like our truck. It does ride rough, that is what a 4x4 diesel truck rides like. The one problem we had since we bought it is the passenger seat belt locks up everytime we use it, which is by law and we have no problem with doing what the law requires in using seat belts. It will start out fine after we put it on, then any slight movement and it will lock up and any more movement will have it keep retracting till it is choking whoever sits in the front passenger seat. The driver's side does not have this problem. Since we have only our truck for transportation this is really aggravating and to us a safety issue, as we have to release it to let it roll all the way up and release again to put it on. Our fear is that it will do this and choke one of us in a accident or cause an accident cause we can't get it to release at all. Please tell us this can be fixed. We took it up to the local Ford dealer and they changed the oil, that cost us $300.00, did an inspection and said it was malfunctioning but want us to pay $450.00 to have it replaced. We talked to the original owner and he said that is one of the reasons he traded it in. To us this has been a problem since it rolled off the assembly line and is a safety feature issue that should of been recalled. Please be advised that if it in fact causes a serious injury or accident we will contact our lawyers to mitigate this issue with Ford.

I have a F-250 2003 with a 5.4 gas engine, I bought it used this past summer. I have noticed the truck seems to seem as if it is bogging down when I'm going about 70mph. I have to keep acelerating. Now my truck will run fine for a few days and then it will die if I stop or decelerate. I've checked the fuel pressue while it was ideling and it was 30psi. But I think the fuel pump is going out. How do I determine if the fuel pump is the problem?
