2021 Ford F-150 Hybrid fuel system problems

Filed Oct 29, 2026 · Electrical, Fuel system · VA

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 the same dealer; I understand a 12-volt battery was replaced. Photographs from that period show Stop Safely Now and other warnings around 70,000 miles. I request investigation of whether that earlier incident and the present faults are related; I do not claim the same root cause has been proven. Exact diagnostic codes and earlier service details should be verified from the dealer records. The October intake odometer was recorded as 99,632; mileage at the highway incidents is not precisely known.

While traveling home on a 2 lane highway 55 on a busy Sunday, the truck started misfiring and jerking, shaking then stalled. Engine light was flashing and we were able to pull off to side as it stalled. After a short time we proceeded on the highway, as we were in a precarious position, about 3 miles and it began misfiring and stalled again. This could have been a tragic situation had there not been a pullout with our travel trailer. We had to have our truck towed to the ford dealer and our RV towed home. While seeking similar cases online we believe it to be a fuel pump driver module and contamination. Our truck VIN is not currently on the national recall list and feel it should be.

The contact owns a 2021 Ford F-150. The contact stated that since purchasing the vehicle, there was a misfire in the engine, the vehicle hesitated and accelerated slowly while driving in gasoline mode and depressing the accelerator pedal. The failure mostly occurred while accelerating from a complete stop. The vehicle was taken to the dealer on several occasions, where the failure was duplicated. The contact received notification of the federal safety agency Campaign Number: 25V455000 (Fuel System, Gasoline), and the dealer associated the failure with the recall; however, the part to do the recall repair was not yet available. The dealer notified the manufacturer of the failure. The failure mileage was approximately 80,000.

The local dealer was contacted and stated that the contact had to pay for a diagnostic test to verify if the failure was associated with the recall. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue.

Experiencing total stop of acceleration in two occasions: 1) when putting the car in reverse and pressing the accelerator and 2) when making a left or right turn after a yield or stop. And when I say loss of acceleration, I don’t mean hesitation, reduced power, or sluggish acceleration. I mean absolutely ZERO acceleration. I’ll press the accelerator and nothing happens. The engine stays basically at idle, and the truck will not accelerate for roughly 5-10 seconds, regardless of how much accelerator I’m giving it. Then suddenly power comes back and the truck drives normally again. This happens with normal operating temps while driving most of the day. It got to a point where it happened once every day. Very scary stuff when you're pulling out into traffic - major safety concerns with oncoming traffic.

I have replaced spark plugs and coil packs due to code saying severe misfiring. However, the root cause of this is the continued open recall of the fuel pump. This has effected the way I can drive my vehicle on daily activities, such as going to work, doing family things, and other things while driving this truck.

On XXX, my 2021 Ford F-150 PowerBoost, VIN [XXX], stalled while I was turning from [XXX] onto [XXX]. My wife and daughter were in the vehicle. The engine lost all power in the intersection. No collision occurred. This is the exact failure described in open safety recall Ford 25S75 / the federal safety agency 25V455 (low-pressure fuel pump). I had already reported the unrepaired recall to the federal safety agency on XXX. I took the truck to LaFontaine Ford in [XXX] the same day. As of XXX, Ford still has no released remedy or parts, the dealer had not completed an inspection, and Ford Customer Care refused a courtesy vehicle. I am submitting a separate 49 C.F.R. Part 557 petition asking the federal safety agency to hold a hearing on Ford’s failure to remedy this recall.

My 2021 Ford F-150 PowerBoost, VIN [XXX], is included in Ford recall 25S75 / the federal safety agency recall 25V455. The vehicle has stalled more than five times and is experiencing the same dangerous condition described in the recall. The Ford dealer told me I can bring the truck in, and they will diagnose the problem and repair it if they can. However, I must pay all costs upfront and then request reimbursement after Ford releases the official recall remedy. I should not be required to pay out of pocket for the diagnosis and repair of a known safety defect covered by an active recall. There is also no clear timeline for when a remedy will become available or when I would be reimbursed. I cannot reasonably be expected to pay now and potentially wait years to recover my money. This vehicle repeatedly stalls and creates a serious crash risk. I am requesting that the federal safety agency investigate Ford’s delay and require Ford to provide an immediate, no-cost diagnosis and repair or provide safe alternative transportation until the recall remedy is available.
