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 After repairs, Ford corporate recommended a 3-year/36,000-mile premiumcare warranty, then rescinded it a week later and offered only free oil changes.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

Went to shut vehicle off and it just kept running. No power inside the cab but the engine was still running and it could run and drive although zero inside electrical. Key was in off position. Very potentially deadly situation.

The contact stated that upon noticing an abnormal burning odor, the vehicle was taken to an independent mechanic, where the wiring underneath the driver's side of the dashboard was replaced; however, the failure recurred.

Several dash warnings came on the dash. Cruise control stopped working, hill assist, parking brake, many others. 4 wheel drive quit working!. I looked on line. Several forums stated to look for a loose connection at the rear of the truck, so it must be a rather common problem. I took the truck to the dealer, they refused to make a warranty repair because the cable was moved when the dump bed was installed. They said the cable was "bent" it is a cable, not a piece of glass. I am sure a new harness will be coiled and not shipped on a 6 ft x 12 ft pallet. . There was an issue with the same thing as I drove home from the dealer after hitting a hard bump when there was only a few miles on it. I called the salesman, but it claered and never returned, until I was in a sever snow storm pulling a trailer. The 4 wd went out causing a partial loss of control.

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.

Since I took delivery of the vehicle the dash goes completely blank at temperatures below 32 degrees and above 90. Ford has been unable or unwilling to fix the problem for over two years resulting in my driving for extended periods with no dashboard information of any kind.

Nhtsa recall 22v337 no horn, no air bags it has been almost a year and I can't get it fixed.

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.

The contact owns a 2017 Ford F-550. The contact stated while driving at 50 mph, the vehicle inadvertently stalled and lost power. There were no warning lights illuminated. The contact veered to the side of the road and was able to restart the vehicle. The contact stated the failure reoccurred that same day as she was pulling to a parking lot. The contact contacted the manufacturer of the battery control circuit who instructed the contact to do a jumper wire to bypass the vehicle issue. The contact stated the issue was resolved. The vehicle was not diagnosed nor repaired by an independent mechanic or dealer. The contact contacted the manufacturer to advise that the recall repair for NHTSA campaign number: 13v265000 (electrical system) was not completed on the vehicle effectively, however the manufacturer informed the contact that the dealer would need to verify that information. The dealer was made aware of the failure and advised the contact they could not assist. The approximate failure mileage was 45,720.

Diesel exhaust fluid system failed shutting down my vehicle while driving and I had to be towed to a Ford dealer. This is a safety issue and could have caused a major accident on the highway. I never got a recall notice about this major problem. Now I am told I would have to spend over $5000. 00 to get this problem fixed. Ford had gotten many complaints about this issue. They should pay to have this repair done. I only had this vehicle for a short time and paid over $59,000 for it. I tried to contact several Ford executives over two weeks ago and heard back from none.

We just had to pay an $800. 00+ bill for pinched wires under the cab of the truck caused by the manufacturer not properly routing the harness, therefore causing a dead short in the truck and causing the replacement of 4 batteries since June 2015. The service writer said this was done by Ford and not covered under warranty! because of the pinched wire the driver had to first step on the brake pedal then turn to key to start.
