RepairPal has identified the most common problems for 50 Ford models based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
A leaking axle shaft seal and / or PTU cover seal can cause transmission (red) or Power Transfer Unit (PTU) (brown) fluid leaks at the axle area. The axle shaft seal and / or PTU cover seal may be leaking and should be replaced as required.
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.
Bulletin 13N02 - This program extends the coverage of the brake booster to ten years of service or 150,000 miles from the warranty start of the vehicle, whichever occurs first. This is a one time repair program.
In some of the affected vehicles, it is possible for the brake booster to develop a small tear in the diaphragm under certain driving and environmental conditions. If this occurs, the driver may hear a hissing noise while depressing the pedal and may also experience a "spongy" pedal feel without a noticeable effect on braking performance. If the vehicle is not serviced, the tear will eventually expand and the pedal effort required to stop the vehicle will gradually increase. However, in all cases, the fundamental vehicle braking system remains functional.
Bad adhesive can cause the foam seal between the dash and windshield to slide out. To correct, the windshield must be removed, and then remove and replace the foam with new parts.
The automatic transmission may develop shifting concerns. On lower mileage vehicles, upgrading the software in the powertrain control module (PCM) and the transmission control module (TCM) may correct the problem. As the mileage increases, internal transmission damage can occur. Repairs could involve replacement of the valve body or a complete transmission rebuild. Whenever major transmission repairs are made, it is important to be sure the PCM and the TCM have the latest software updates to help prevent these issues from reoccurring.
The common problem for ignition misfires are ignition coils going bad. Replacement of the bad ignition coil is necessary. These should be fixed as soon as a problem is detected. Otherwise the misfire can cause damage to other components.
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.
A knocking noise from the upper engine area may indicate a loose intake runner. Our technicians tell us if this is the case, replacement of the upper intake clamshell will be necessary.
There are reports of failures of the CCRM or Constant Control Relay Module. The CCRM has relays and switches inside that control or provide power to the engine cooling fan, AC clutch (to engage the AC compressor), fuel pump and powertrain control module (PCM). Single switches or relays can fail internally causing a number of different symptoms including no start conditions (inoperative fuel pump or PCM), engine running warm due to inoperative cooling fan, or the AC might not blow cold air.
Bogging, hesitation or stalling may be experienced during moderate to heavy acceleration. This can be caused by a failing of many sensors or modules in the fuel injection system. It is recommended to have an experienced shop perform diagnosis to find the root of the problem.
If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, this could be caused by a failing differential clutch kit. An updated differential clutch kit available.
The Ford F-150 has known issues with the V8 engine ejecting spark plugs. This will make a tapping or knocking noise, plus the engine will begin to misfire at all speeds. The check engine light will also illuminate.
The threads on the cylinder head are too short and soft, allowing pressure from combustion to overwhelm and destroy the threads.
When the spark plug ejects, the cylinder head becomes damaged, necessitating repair of the spark plug port threads, or replacement of the cylinder head and cylinder head gasket.
Ford has recommended a method of repair for the cylinder head that prevents the spark plug from ejecting under future use. Replacement of all spark plugs is not necessary, but an updated spark plug design can help prevent this from happening in the future.
There is a technical service bulletin for the V8 engine.
