I had my truck serviced, engine oil and fuel filters replaced, I picked up truck and while driving home, engine loss of power came on screen, truck then stalled, I observed smoke coming from under the hood, I exited vehicle to try and open hood, but flames were already present, I called 911 fire department came and put fire out. truck is a total loss. Fire Capt observed that fire seem to have started near the fuel filter housing, I was fortunate to escape the cab along with my dog, I have read several reports about filter housing leaking and starting fires, my brother inlaw, actually had the same issue, filter split causing fuel to leak, but fortunately he had just started the truck and was not driving very long before he smelled the fuel and was able to shut down the engine before it got hot and repolace the faulty filter housing.

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 After repairs, Ford corporate recommended a 3-year/36,000-mile PremiumCare warranty, then rescinded it a week later and offered only free oil changes.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.

Ford Motor Company has had a known issue with the truck frames cracking on the F-550 chassis. They acknowledged it by doing a recall, which either replaced or repaired the chassis frame or installed reinforcement braces if no cracks were visible. The recall expired in September of 2023. In October 2023 we noticed a crack on the frame just outside the recall reinforcement brace that Ford-certified technicians installed. We found another in November (reinforcement brace installed) and another in January (with Ford's new and improved frame produced due to a recall issue). Ford has denied making the repairs since the original warranty expired, even though this was the same related issue. We have been dealing with Ford Motor Company since October in hopes of resolving the issue but they continue to give us any resolution. The problem has not only caused a burden on our workforce but also caused great safety concerns. With Ford avoiding responsibility, they are allowing trucks to operate daily on our highway system, which becomes a safety concern for not only the driver but for many other motorists. The problem existed, but the issue was not resolved, all we are asking is that they take responsibility for making the repairs and permanently resolving the issue for the safety of all motorists.
