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.

After multiple attempts coming after multiple attempts to call the dealership and corporate with no answer, forced to leave a bad survey and then someone contacted Follow-Up Actions: The dealership attributed the issue to a missing 10-amp fuse. However, prior warnings from the FordPass app indicated powertrain malfunctions since October 2024. A subsequent recall notice (24S78/24V957) in January 2025 highlighted potential high-pressure fuel pump issues leading to power loss. After multiple attempts coming after multiple attempts to call the dealership and corporate with no answer was forced to leave a bad survey and then someone they’ve let me leave the dealership twice now saying that there was nothing wrong with my truck and then to find out that there’s a recall a couple weeks later Safety Concerns: The unexpected power loss and control failure pose significant safety risks. The recurrence of issues post-recall raises concerns about the effectiveness of the initial repair and overall vehicle safety.

While driving down the road at approximately 45 mph, under normal conditions, with no warning indicators the low fuel pressure light came on. When the driver stopped the vehicle he lost all power and observed smoke emanating from the underside and hood of the vehicle. Prior to him exiting the vehicle he observed flames shooting out from under the console towards his feet. Upon exiting the vehicle I saw flames under the hood of the vehicle and utilized his supplied fire extinguisher to attempt to put the fire out. This was futile and to our benefit he had a pressure washer and 119 gallons of water that he was able to put into action to subdue the fire. Noting that the drivers side front fender melted off and a hole melted in the drivers side hood from the fire. The entire engine compartment was burned as well as melted components and plastic in the passenger compartment of the vehicle from the fire.
