At ~93,000 miles, my 2020 Ford F-550 (7.3L “Godzilla” V8) suffered catastrophic engine failure due to a roller lifter bearing failure, causing internal valvetrain damage and requiring full engine replacement. Ford dealer stated they recommended 90% coverage of the repair under goodwill through corporate, but later reduced coverage to 40% without explanation. After repairs, Ford corporate recommended a 3-year/36,000-mile PremiumCare warranty, then rescinded it a week later and offered only free oil changes. The 7.3L engine in my truck shares the same design as the F-53/F-59 motorhome chassis, which have multiple Technical Service Bulletins (TSBs) for lifter bearing failure, overheating of cylinders #2–3, and low oil pressure at idle. My vehicle shows identical symptoms but was excluded from those VIN ranges, suggesting Ford is segmenting related defects to limit recall exposure. Inspection revealed a cracked and arcing spark-plug wire on cylinder #2, matching the motorhome TSB’s overheating issue. This arcing poses a fire risk and likely contributed to localized heat and mechanical failure. The truck was often driven in Eco Mode, which holds low RPMs under load. This can increase cylinder pressure, reduce oil flow, and exacerbate heat in cylinders #2–3—factors that align with the failure pattern. This combination of design-related overheating, lifter bearing failure, oil-pressure fluctuation, and spark-wire arcing presents a clear safety hazard. Engine stall or fire could occur under towing or heavy-load conditions. NHTSA investigation is warranted into Ford’s 7.3L Godzilla engine design and VIN-exclusion practices.

A clogged fuel filter caused an engine fire. There were no warning lamps, messages or other symptoms prior to the failure. The fuel filter has been known to be problematic for these trucks, in yet there has been no recall. A simple google search shows these fires are common. The vehicle has been in for service at the dealership many times but no one checked on the faulty fuel filter positioned above the hot engine components.

Our company has been proactively replacing some of the older fuel filters in our fleet as part of a safety campaign. A fuel filter on VIN [XXX] was replaced yesterday (XXX) with a Ford Motocraft filter. Today (XXX), the operator was driving the unit when they started to smell smoke in the cab. By the time they pulled over, the cab had smoke inside and the operator had to get out. The operator opened the hood to let it vent and called the garage to have the unit towed. After inspection by the garage, they found that the secondary fuel filter was leaking extensively from the seam.
