Ford F-350 Super Duty: Usual Issues and Problems Reported by Its Owners
The Ford F-350 Super Duty may be large and heavy. But even with all the bulk and power packed inside, the Super Duty truck also has some vulnerabilities. Here's a list of some of the usual problems of this Ford truck. Some of the issues were reported by owners; others were addressed through service bulletins and recalls.
Based on user reports and complaints, common problems in Ford F-350 Super Duty are found in the fuel system. Usual complaints include the delamination of the fuel tank, which can lead to lost power due to clogged fuel filters. This problem can result in a broken fuel injection pump or injectors. A service bulletin regarding this has been released.
A faulty high-pressure diesel fuel injection pump was also cited as a common problem that causes the truck to be stuck in a no-start condition. In some cases, the pump has to be replaced entirely, while in other instances, the problem can be corrected through repair.
The Ford F-350 Super Duty also seems to have issues with ignition and lack or loss of power. A good number of owners have reported ignition coil failure because of the large spark plug gap. The solution to this is to replace not just the spark plugs but also the coils and the coil boots. Another common problem is lost turbocharger boost to the engine that result in lack of power. This is usually caused by a loose hose from the turbocharger to the intake manifold. For those experiencing a \"no start\" problem in their diesel engines, the cause may be attributed to a chafed wiring to the high-pressure fuel pump, which causes the pump to stop working or to fail. While the engine may crank, the vehicle may not start at all. The wiring needs to be inspected and changed.
Truck owners have also complained about spark plugs that are hard to remove and plugs that may be disconnected from the cylinder head. Plugs that are ejected from the cylinder head can cause damaged threads. For trucks that are still under warranty, the cylinder head should be checked and replaced. For those whose warranty has run out, thread inserts may fix issues with the cylinder head.
Ford has issued recalls for F-series trucks, including the F-350 Super Duty. The trucks that were subjected to the most recent recall have a 6.2L gasoline or 6.7L diesel engine and 6R140 transmission. They were manufactured from September 2013 to March 2014. The reason for the recall is a transmission calibration problem caused by a control software error. This error can very well lead to unexpected vehicle movement. As the gear shifts from Park to Drive, the vehicle may be set to Reverse before engaging to Drive. Check the service bulletins from NHTSA for other recalls that involve this Ford Super Duty model.
