2017 Ford F-350 Super Duty

The Bosch CP4.2 high-pressure fuel injection pump on the 6.7L Power Stroke diesel can fail catastrophically, sending metal debris throughout the entire fuel system. Contaminated fuel damages the injectors, fuel rails, fuel lines, and fuel tank. The failure often occurs without warning and results in immediate engine shutdown.

Replace the CP4.2 pump and flush the entire fuel system, including injectors, fuel rails, lines, and tank. The repair is extremely expensive. Many owners install a lift pump or fuel filtration system as preventive measures. Some aftermarket companies offer CP4 disaster prevention kits. Ford has faced class-action litigation over this issue.

The DEF injection system is prone to multiple failures including DEF quality sensor errors, DEF heater faults, SCR catalyst inefficiency codes, and injector clogging. When the DEF system enters a fault state, a 5-mph limp mode countdown begins after a set number of miles, eventually making the truck nearly undrivable.

Diagnose with a scan tool to identify the specific DEF component failure. Common repairs include replacing the DEF quality sensor, DEF heater element, DEF injector, or the entire DEF tank assembly. Ford issued multiple TSBs addressing DEF system faults. Use only API-certified DEF fluid.

The Super Duty is prone to a violent front-end oscillation known as 'death wobble' that occurs after hitting a bump at highway speeds. The steering wheel shakes violently and uncontrollably, requiring the driver to slow down significantly to stop the oscillation. Worn steering and suspension components are the root cause.

Ford issued TSB 19-2305 addressing Super Duty front-end shimmy. Replace the steering damper with a Fox or Bilstein heavy-duty unit. Inspect and replace worn ball joints, tie rod ends, track bar, and track bar bracket. A loose track bar bracket bolt is the most common single cause. Have the front end aligned after repairs.

The variable geometry turbocharger on the 6.7L Power Stroke can develop wastegate actuator problems, causing overboosting, underboosting, or turbo surge. Symptoms include loss of power, excessive black smoke, check engine light with boost pressure codes, and a whistling or squealing sound from the turbo area.

Replace the turbocharger wastegate actuator or the entire turbocharger assembly if the internal vanes are damaged. Clear the DTC codes and perform a turbo relearn procedure. Ford issued TSBs addressing turbo calibration issues. Ensure the exhaust back-pressure sensor is functioning correctly.

Dual rear wheel (DRW) F-350 models develop rear axle hub seal leaks that allow gear oil to seep onto the brakes and wheels. The leak is visible as an oily film on the inside of the rear wheels. Contaminated brake pads and rotors lose braking effectiveness and create a fire risk.

Replace the rear axle hub seals on the affected side. Inspect the rear brake pads and rotors for oil contamination; contaminated pads and rotors must be replaced, as they cannot be cleaned. Check the differential fluid level and top off with 75W-140 synthetic gear oil.

Ford Motor Company (Ford) is recalling certain 2015-2019 Ford F-150 and 2017-2019 Ford F-250 Super Duty, F-350 Super Duty, F-450 Super Duty, and F-550 Super Duty pick-up trucks equipped with an engine block heater. Water and contaminants may get into the block heater cable's splice connector causing corrosion and damage.

When the heater is plugged in, prolonged corrosion could cause a resistive short, increasing the risk of overheated or melted wiring which can increase the risk of a fire.

Ford will notify owners, and dealers will disable the block heater cable, free of charge. Once parts are available, Dealers will replace the engine block heater cable, free of charge. The recall began June 3, 2019. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 18S45.

Ford Motor Company (Ford) is recalling certain 2015-2017 F-150, and 2017 F-250, F-350, F-450, and F-550 vehicles originally produced with black or body colored exterior door handles that may have been subsequently equipped with a chrome exterior door handle cover accessory kit purchased from a Ford dealer. These accessory door handle covers may cause the doors to unlatch in a side impact collision. As such, these vehicles may fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 206, "Door Locks and Door Retention Components."

If the doors unlatch and open in a side impact collision, the occupants have an increased risk of injury.

Ford will notify owners, and dealers will remove the accessory covers and refund the purchase price. The recall began July 13, 2017. Owners may contact Ford at 1-866-436-7332. Ford's number for the recall is 17C09.
