What 2015 Ford F-550 SD owners say
Engine & cooling
Operator was driving the vehicle when it experienced a fire in the engine compartment.
Tl* the contact owns a 2015 Ford f-550 SD. While driving approximately 30 MPH in reverse, the vehicle stalled. The vehicle had to be pushed into the contact's driveway. There were no warning indicators illuminated. The vehicle was taken to the dealer four times, but the failure could not be duplicated. The failure also occurred while in drive. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 25,000.
Fuel & propulsion system
My f-550 super duty diesel dump truck lost power on the highway because of a known fuel injector pump defect. The pump exploded into metal pieces that clogged all fuel lines leading to a loss of power on a highway putting everybody at risk of a collision. This fuel injector problem is known to ford and is subject to class action lawsuits. The dealer confirms that this is the problem. Apparently for the last decade, this pump has been known to fail because it was designed for European diesel not American diesel which because of the low sulfur content makes the pump cavitate because of lack of lubrication and explode. There was no indication of failure prior to the incident.
This submission is more related to a brand-new fuel line that was purchased from the Ford dealer for this vehicle upon failure of the existing line. When the new line was removed from the packaging, the mechanic inspected the clip that secures the line to the secondary fuel filter housing. It was observed that the brand-new clip was defective and that even the slightest touch of the clip would unlock the line. It is believed that if this line were installed in the vehicle, the vibration of the engine could potentially unclip the line causing fuel to spray in the hot engine compartment. The line was retained and can be provided for examination.
