2021 Ford F-150 fuel/propulsion system problems

“My 2021 F-150 PowerBoost hybrid repeatedly lost propulsion while traveling on the highway in early October 2026, including four incidents on one trip around October 3. At approximately highway speed, the tachometer dropped to zero while the selector remained in D, and the truck coasted as if in neutral. There were harsh shifts around 9th/10th gear and difficulty accelerating beyond approximately 70 mph. A vehicle warning appeared. Disconnecting and reconnecting the battery temporarily restored operation. Sudden loss of drive power in highway traffic created a collision risk. The underlying cause has not been independently established. A Ford dealer's October 2026 inspection recorded an internal transmission hydraulic leak, clutch-disconnect trouble codes suggesting a hybrid drive unit concern, a recommendation to replace the transmission with the hybrid drive unit, and high-voltage battery cell-balance DTCs. More recently electric-driving mileage has remained at zero and the gasoline engine continues running while stationary. Severe shifting and vibration had varied between 2H and 4A modes. Around June 2025 the vehicle also stopped operating and was towed to…”

“fuel pump has failed, vehicle shut off while driving, ford dealership has confirmed failed fuel pump under the 25s75 recall, check engine light illuminated with fault code P008A (fuel system low pressure) fault code moments prior to vehicle shutting off, vehicle would not restart”

“Fuel pump failed while driving causing vehicle to be disabled in a roadway blocking traffic. The vehicle was then incapable of shifting to neutral so that it could be moved out of the roadway. A Ford dealer confirmed the faulty fuel pump and replaced the part. Ford appears to know this is a safety issue as per recall campaign 25S75/25V455 but they have refused to pay for the replacement fuel pump.”

“My husband was driving on the highway with my two daughters in the car when the vehicle stopped driving and he was barely able to pull off the road. It appears to be a defective low-pressure fuel pump. This is an active recall for this model and year, however Ford says that our specific VIN was not involved in the recall. My family could have been killed in this incident!”

“We broke down because the fuel pump broke, which has a recall out there. We had stopped at Buc-ee’s for a break and when we got back to the truck, it wouldn’t start back up. We got it fixed at Banner Ford and were forced to pay 1822.50 for a fix that a known recall is out for that they claim there’s no remedy for. But, then you’re telling me you can fix it for 1800. It makes no sense that we have to pay for something that there’s a recall for. We are just trying to get our money back.”

“I own a 2021 Ford F-150, VIN [XXX]. NHTSA recall 25V455 / Ford recall 25S75 affects my vehicle because of a potential fuel-pump failure that can cause loss of fuel pressure and an engine stall while driving. The recall was issued XXX, and my vehicle still shows an unrepaired recall with the remedy not yet available. I am concerned about the length of time that has passed without a repair being available for a safety-related defect that could cause the engine to stall while driving. I am requesting that NHTSA review the continued delay in providing a remedy.”
