    Ford Motor Company deployed an over-the-air software update to my 2018 Ford F350 that corrupted the Body Control Module. The software error permanently locked the vehicle into a speed-restricted 'MyKey' safety mode, leaving me with an altered vehicle and no admin access to bypass it. Ford Corporate is refusing to fix the corrupted software deployment. I do not and never have had a second key and they are now saying I must purchase this and pay for my truck to be reset.

    Our 2018 Ford F-350 Super Duty diesel with the 6.7L Power Stroke engine has a well-known, massive fuel system concern involving the Bosch CP4 high-pressure fuel pump. This pump failed and it sheds metal shavings throughout the entire fuel system. Repair cost $13k. Per other consumer and google results: The CP4 Fuel Pump Issue. The Defect: The Bosch CP4 pump is designed for European diesel fuel, which has more lubrication than American diesel. When it lacks sufficient lubrication, it can score itself and self-destruct. The Damage: Metal debris floods the fuel rails, lines, and injectors, requiring a complete replacement of the fuel system components.

    My truck's tailgate has started opening on its own while driving, again. Previous recalls on this issue were performed when parts were available. This is a safety hazard to anyone behind me if anything falls out of the truck bed while driving. Today, 2/3/2026, it opened again. A bucket fell out of the truck bed. Fortunately no one was behind me. My truck is available for inspection. I have not contacted the dealer yet for their inspection/diagnosis. There are no warnings when this happens. It has forced me to strap the tailgate so it can't open unexpectedly.

    Steering Effort Control Module failed. This is a known concern with these vehicles. Many Super Duty's have this happen. It is a very expensive repair. The steering effort changes, the vehicle becomes out of alignment and other things like cruise control, wipers, etc may fail as part of this issue.

    The car had not been driven and was only in use for about 20 minutes. Then, the check engine light came on. I was planning to take the next exit to investigate. About a minute after the check engine light came on, several other lights came on. They stopped about 20 seconds later. The car began to smoke and as I was pulling over, smoke began to enter the cab. When I pulled over, the car began was on fire. Highway patrol and Cal Fire arrived. Cal Fire put the fire out. It was a total loss. Highway 101 was shut down for a bit while the truck was on fire.

    The panoramic vista sunroof began allowing air while driving. Then the mechanism began not working properly. This all resulted in the track breaking and caused the entire system to stop working. While driving on highway or freeways, the glass would open and could not be secured properly. Could have caused the glass to become a projectile object. Upon researching this issue, I found several complaints for the panoramic vista sunroof for Ford/Lincoln's from 2017 to 2019. TSB # 18-2374. We have a 2018. To be clear; this was a progressive issue that started in 2021 and simply thought it to be the windy conditions outside the vehicle. Then the issue became worse even after being regularly serviced and repaired. By 2024, the track broke completely. Resulting in a complete replacement.
