Most reported Ford F-350 Super Duty problems
The high pressure diesel fuel injection pump may fail, resulting in a "no start" condition.
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.
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.
Software enhancements are available to remedy inconsistency and confusion about the Diesel Particulate Filter (DPF) cleaning cycle - “Regeneration” mode. The Powertrain Control Module (PCM) will need to be reprogrammed to add several enhancements, including a more reasonable driving experience during the cleaning cycle and instrument cluster notifications of the cleaning status.
The rear sliding glass window may stop working, or binds in motion. The power slider cable binds causing slow, or no operation. The glass assembly will need to be replaced, the cable is included in the assembly.
It is common to see the variable vanes inside the turbo seize or bind from carbon buildup. This causes an overboost or underboost condition when driving.
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.
If the driveline angle is out of adjustment, it can cause shuddering from the vehicle when accelerating from a stop. The driveline angle should be adjusted to reduce vibration in most driving conditions.
If the engine cranks but will not start, this may be caused by damaged wiring to the high pressure fuel pump. Wiring to the pump can be chafed, which causes the pump to stop working. The chafed wires will need to be accessed and repaired.
