2021 Ford F-150 Hybrid: engine stalls while driving

Filed Oct 5, 2026 · Engine, Fuel system · ID

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.

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.

On July 15, 2026, I took the vehicle to Lafontaine Ford for maintenance and to address open recalls. I was informed that the open recall for the low-pressure fuel pump (campaign 25S75) did not have a solution available. Due to the severity of the recall, I contacted the Ford Customer Care Center. A representative stated that a solution would be available on July 17, 2026, and that they would contact Lafontaine Ford to prioritize the vehicle for repair on July 18, 2026. On July 17, 2026, I followed up with Lafontaine Ford and confirmed they had received no contact or notation from Ford regarding prioritization. Lafontaine Ford also stated they had no information on when parts would become available and that nothing could be done at that time. I then contacted the Ford Customer Care Center again because no action had been taken, even though the recall has been open since approximately July 8, 2025. A Ford Customer Care Center representative confirmed that no remedy was available for my model year and that they did not know when one would be available. Due to the seriousness of the recall, I requested a courtesy vehicle. The Ford representative contacted Lafontaine Ford regarding this request and then disconnected the call. The Lafontaine Ford representative informed me they could not provide a courtesy vehicle without written confirmation from Ford due to the dealership having no reasonable timeframe of when parts/remedy would be available. When I called the Ford Customer Care Center back and explained what Lafontaine Ford had told me, I was treated indifferently and was disconnected twice. I eventually spoke with a supervisor who refused to escalate the concern or provide any assistance with the documentation Lafontaine Ford said they needed in order to provide a courtesy vehicle. The low-pressure fuel pump is the component identified in the recall and can fail, resulting in loss of engine power or stall while driving. This creates a significant safety risk, part

Several times, the vehicle has failed to accelerate or respond to accellerator pedal input for several seconds. It seems to happen when switching from electric to hybrid modes, and when shifting between lower gears simultaneously. Once the switch to hybrid occurs the engine will rev high with some acceleration even if the accelerator pedal is no longer being pressed. This acceleration has happened when I had my foot over the brake pedal in anticipation of pulling over to stop since the truck would not accelerate. There are no warning lights or messages that appear on the vehicle. It is dangerous because it seems to happen when trying to accelerate from a lower speed. If it happens when trying to change lanes in stop and go traffic or while pulling into traffic other cars would have to brake hard to avoid hitting our vehicle that has experienced stalled acceleration. It is also dangerous because once the transition happens there is brief uncommanded acceleration.

When making 90° turns such as an immediate right turn or a left turn across one lane, gas pedal becomes completly unresponsive halfway through the turn for approx 3 seconds. Occurs about 1% of the time but drastic when it occurs. Almost multiple accidents have occured with oncoming traffic almost t-boning me when making left turns or being rear ended on right turns: people don't anticipate a vehicle stalling and slowing down when entering traffic and people have swerved into other lanes or the shoulder to avoid a collision. When this occurs, it is like the vehicle goes brain dead, the gas pedal can be pushed to any threshold including floored with no change to speed; rpms dont even increase. Vehicle has been through Ford troubleshooting multiple times and at one point early on, had a Ford engineering/ specialist working remotely with the dealership. Findings from this specialist: two upcoming ota updates will be released that will resolve this concern. One of the updates was in regards to the trailer brake module and the other something else as equally ridiculous as not pertaining to my issue. OTA updates came and issue never went away. Years later, multiple appointments with techs saying unable to duplicate. Dealer now saying they have no record of working with a specialist even though I have the service records from them stating this and electronic communications from Ford regarding this. The issue is not resolved and still occurring. Vehicle now out of warranty so likely will never be repaired. Not faithful in thinking the federal safety agency will care, they didn't care when this vehicle had complete brake failure at 7k miles which was later found to be due to incomplete or bad programming, but maybe this will help others know they are not alone if experiencing this issue.
