What 937 owners told NHTSA about the 2021 Ford F-150 Supercab

Truck has just started misfiring out of the blue, have had Ford dealerships look at it, have changed all 6 spark plugs and one ignition coil. The recall NHTSA 2025-366 may be the reason, it states there still is no remedy for this, recall was issued 1 year ago, July 2025. I need this remedy.

2021 Ford F-150 Lariat, 5.0L Coyote V8, purchased new, now 65k miles. Two interrelated safety defects: OIL CONSUMPTION: On 3/21/2026 at 62k miles, I discovered the engine was critically low on oil. Only 3 quarts drained during a full oil change, against a rated 8.8 quart capacity. The engine had been running on one third of required oil. The onboard oil life monitor showed 9% remaining and gave NO low-oil warning, no warning lights, no alerts. No external leak. On 5/22/2026, Koons Ford Woodbridge formally confirmed excessive oil consumption after a documented oil consumption test. Ford TSB 19-2365 acknowledges this exact defect on the 5.0L Coyote for 2018-2020 model years, attributing it to high intake manifold vacuum during deceleration fuel shut-off pulling oil into the combustion chamber. The 2021 engine is mechanically identical. TRANSMISSION: Hard and slipping gear shifts reported to Ford within months of purchase in 2021. Ford issued multiple software updates over the years to mitigate the behavior, most recently late 2025. Fix was temporary; hard/slipping shifts returned. CATASTROPHIC FAILURE: While awaiting Ford HQ authorization on repairs, the vehicle suffered complete drivetrain failure on Friday night. Engine lost power and transmission failed entirely. I was near home and coasted safely off the road. Had this occurred at highway speed during my daily commute, the result could have been catastrophic. Vehicle towed to Koons Ford Woodbridge. SAFETY CONCERN: This is my only vehicle, used for daily highway commuting. The oil consumption defect provides no warning before engine damage. The transmission has degraded despite years of Ford software patches. The vehicle has demonstrated total drivetrain failure capability with no driver warning. Ford Corporate case opened: CXH-07446845-G0J0K0. Filing to document this at the federal level and add to the existing pattern of complaints. Requesting NHTSA review whether these defects warrant investigation.

This is a continuation/escalation of NHTSA complaint 11689917. My 2021 Ford F-150 has experienced repeated fuel-system/electrical fuel-pump failures. The vehicle previously stalled and later cranked but would not start, returning code P0627 “Fuel Pump A Control Circuit / Open.” The in-tank fuel pump was replaced at owner expense for approximately $1,400 at an independent service center in September of 2025, but the repair did not permanently resolve the issue. The vehicle has now again lost fuel pressure/propulsion while traveling approximately 50 mph on a two-lane highway in a similar manner to prior failures. I was able to get the vehicle off the roadway, and it required towing back to my residence. This is approximately the fourth or fifth fuel-related failure, including stalls at low speed and non-start conditions related to fuel in parking lots. The symptoms appear consistent with Ford/NHTSA recall 25V455 / Ford recall 25S75, but my VIN was not included in the affected group. I am concerned that the recall population may be too narrow or that the remedy does not address the full defect pattern.

The truck rapidly accelerated while I was slowly rolling into a parking spot with my foot on the brake. The harder I pushed the brake the more it seemed to accelerate. I luckily avoided hitting anything. I forced the gear shifter out of Drive into park. No warning lights or messages. I contacted 3 Ford dealerships and all said they haven’t heard of this nor do they think they could identify this problem if I brought it in.

I have been trying to get a recall situated with Ford now for almost a year. They say they have no fix. I am making payments on truck and can’t use it like I should be. Even came out of my own pocket and had ford install a new fuel pump however problem came back. Just not fair I purchased a vehicle from A reputable company and they will not help me at all. Not even a loaner.

While driving my 2021 Ford F-150, the vehicle suddenly began shaking, lost power, and shut off completely while in motion. This created a dangerous situation as I was left without acceleration while driving. Prior to the failure, there were no major issues with the vehicle. After the engine shut off, a battery warning appeared, but the battery had been in good condition and less than a year old. The vehicle would not restart and had to be towed to a Ford dealership, where it has remained for over two weeks. Independent mechanics and the dealership have both indicated the issue is related to the fuel system. I later discovered this matches an active recall for the low-pressure fuel pump. Despite this, I was informed there is currently no remedy available for the recall. The vehicle is still at the dealership and has not been repaired. I have not been provided with a loaner or rental vehicle and have been left without transportation for work or to care for my children. I have also been asked to pay out of pocket for towing and battery replacement, even though the failure appears to be related to a known recall issue.

We have already filed a report regarding multiple unresolved warranty defects that Ford Motor Company has refused to address for over a year. Among these is a recurring fuel pump failure—an issue that has now occurred multiple times. The most recent incident happened just a couple of weeks ago in the Twin Cities after being told by our dealer that there was not an issue or fix for the fuel pump issue, where the truck stalled in active traffic, creating a situation that could have resulted in serious injury or worse, death! Despite repeated attempts to resolve this matter, Ford’s latest response is unacceptable and has directly led to this additional complaint. We have been told that no action will be taken unless we personally drive this unsafe vehicle to a dealership for inspection. When we made it clear that doing so would put us at risk, we were dismissively told to have it towed if we were unwilling to drive it. Let us be absolutely clear: we will not endanger our lives to accommodate Ford’s refusal to honor its warranty obligations. We are being asked to operate a vehicle with known, unresolved defects that have already proven dangerous. This is not only irresponsible—it is indefensible. If this matter is not addressed immediately and appropriately, we will have no choice but to escalate further.

I’ve had the transmission replaced along with the torque converter when both failed less than a year ago. The transmission AND the torque converter are now doing the same thing it was doing prior to the replacement. The transmission slips in 4th, 7th and 8th gears. The torque converter whines loudly. Ford will not fix the issues with these transmissions without a hefty out of pocket fee. It’s become very well known that all of these 10R80 engines/transmissions are a major problem that ford is not remedying. If this transmission gives out when I’m on the interstate it’s going to cause a major wreck. I live in the mountains, so a bad transmission can quickly turn into a deadly accident. These transmissions need a permanent fix, not for us owners to continue paying thousands of dollars for replacements or rebuilds. This is fords problem.

The engine system in the 2021 Ford F-150 is malfunctioning due to excessive oil consumption, in the 5.0L Coyote V8 engine. This is leading to no oil registering on the dipstick; the vehicle and its engine remain available for inspection upon request as they are in the owner's possession and have not been disassembled or repaired. This issue puts the safety of the driver, passengers, and other road users at risk by increasing the chances of engine seizure, overheating, or sudden power loss during operation, which could result in loss of vehicle control, especially at high speeds or while towing, potentially causing accidents, breakdowns in traffic, reduced braking efficiency, or even fires from overheated components, though no such incidents have occurred yet. The problem has been reproduced and confirmed by technicians at Ford Spitzer in Hartville and Valvoline in North Canton, OH, who documented the oil consumption during service visits, consistent with Ford's diagnostic procedures. The vehicle has been inspected by the dealership, which is in communication with Ford corporate for further guidance on warranty repairs, but no inspections by police, insurance representatives, or other third parties have been reported. The main symptom observed is the consistent lack of oil on the dipstick, technicians documenting the engine is as low as 2-3 quarts, indicative of rapid consumption. No warning lamps or dashboard messages have appeared yet, but they could activate if oil levels become critically low, and the exact onset timeline ties to routine maintenance after several thousand miles.

My son is a mechanic and realized there was an issue. He found this issue: The engine loss compression on number four-cylinder severe power loss inspected; found damage to top of number four piston, most likely due to valve failure. He took to Ford dealership in Tuscaloosa, AL. They agreed with the assessment. Ford Motor Co.would not repair, stating this issue was not caused by recall.

The contact owns a 2021 Ford F-150. The contact stated that while driving approximately 40 MPH, the check engine warning light illuminated with an abnormal rattling sound coming from the engine compartment. The Ford App indicated a timing failure. The vehicle was not diagnosed or repaired. The contact believed that the failure was associated with an undisclosed recall. The manufacturer was not notified of the failure. The failure mileage was approximately 58,000.

The vehicle is experiencing a chronic, documented loss of engine coolant with no external leaks identified, accompanied by a persistent odor of burning coolant. Despite nine months of notification and two separate Ford authorized dealerships attempting repairs, the defect remains unresolved. To date, dealerships have performed only 'surface-level' pressure and dye tests. They have refused to perform thorough diagnostics despite the clear evidence of consumption. This creates a severe safety hazard: coolant loss on this engine platform is a known precursor to sudden engine stall and potential engine fire. By failing to identify the internal leak path, Ford is requiring me to operate a vehicle with an unpredictable mechanical deficit. The absence of a Warning Lamp (CEL) does not mitigate the risk; it confirms a mechanical failure that the current onboard diagnostics are failing to capture before a catastrophic event occurs.

Guessing the date below Truck shuts off when trying to take off and go. This has happened a few times and even pulling onto a main highway. This is a very dangerous situation, and I have contacted Ford and they have stated there is no fix for this. I have contacted Carvana which is where I recently purchased the truck within the past month and they state the recall was listed and there's nothing they can do it's up to Ford to fix a recall. They will not take the truck back and now we are stuck paying for over $30,000 on this truck and it keeps stalling on us. We cannot afford for it to just sit in our yard and pay for it if it's not running. We need help to get this fixed. We have no idea what's causing it but assuming it could have everything to do with the open recall or the battery. That battery is over $4000 if we have to replace it. Another thing we noticed is the LED lights on the headlights went out randomly and haven't come back on. Another very expensive fix for a truck we just purchased less than a month ago. We took the truck in the shop within the first few days of owning it due to a few issues we felt were not right like pulling to one side, feeling as if it were going over rutted areas on the roadways with a bump and jerk to it as well like it was a transmission issue. The insurance company with Carvana choose the place to take it to and we dropped it off and the next day they called and stated nothing was found to be wrong with it and Carvana knew we were out of return in time to replace it when they had us drop it off it was like another day.

Due to waiting for a recall fix for ( NHTSA #-25V455 ) My F150 Raptor has been having all listed failing issues, Miss fire at idle or when fuel is hot, issue starting on a handful of times. I have been driving it after 4 -5k miles of this and I was alerted today after replacing ( All Injectors, Coils, Spark Plugs, ETC ) That I may need a new engine. This could have caused a crash and is now costing me an entire engine due to no fix or parts availability. Thousands of Dollars for a new engine out of my pocket due to fuel starvation. Cylinder 4 Miss fire's at idle. They appeared once I returned home from the mountains back to texas with hot weather.

Description of Incident: The vehicle exhibits a severe and unpredictable transmission "shudder," "stutter," and hesitation during gear synchronization, specifically during 1st–3rd and 8th–10th gear transitions. This manifest as a violent "shaking" sensation and a loss of momentary acceleration while merging into high-speed traffic. This issue was first reported to an authorized Ford dealership on December 17, 2024. At that time, the vehicle exhibited harsh shifting and "shuddering" consistent with Ford Technical Service Bulletin (TSB) 22-2428. Despite being under a 150,000-mile service contract, the dealer misdiagnosed the mechanical transmission defect as an engine misfire, resulting in ineffective repairs. The defect has persisted and worsened. The internal failure has been identified as a defective CDF Clutch Drum (Cylinder) where an internal bushing moves out of place, obstructing fluid flow and causing mechanical "slip." This is a known manufacturing defect documented in multiple Ford TSBs (22-2428, 23-2250, and 24-2101). Safety Risk: The failure causes unpredictable power delivery. On multiple occasions, the vehicle has hesitated or "stuttered" while attempting to merge onto highways or cross intersections, leaving the vehicle vulnerable to side-impact or rear-end collisions. The lack of consistent throttle response and the violent nature of the shifting creates a significant safety hazard for the driver and surrounding motorists. Verification/Inspection: The symptoms were reported to a Ford dealership multiple times. As of December 2025, the dealership has opened a formal case with the manufacturer to verify the internal "cause of failure" by the Shop Foreman. No warning lamps or Diagnostic Trouble Codes (DTCs) appeared on the dashboard, as the failure is a mechanical internal bushing slip that does not always trigger a software sensor until total failure occurs. The vehicle is available for inspection.

I started smelling gas in the cabin of the truck when I came to a stop. As I was driving on the freeway I noticed my gas gauge going down rapidly. Within minutes I ran out of gas. Got the truck towed to Ford dealer. After diagnosing the issue I was made aware by Ford service department that one of the high pressure fuel injector cracked and was spraying gas out which caused me to run out of gas. With gas spraying in the engine I was at severe risk of a fire. No warning lights or messages appeared when this happened. After investigating I noticed Ford has a recall for this issue for other vehicles but not the F-150.

Vehicle lost all power and stalled while driving. Vehicle also stalled at idle when waiting at an intersection, and another time while waiting at a stop sign. No longer starts. Appears to not be receiving fuel and is returning code P0627 "Fuel Pump A Control Circuit / Open" and will crank but not start. Required towing back to my residence. FordPass sent a "Service Engine Soon Warning" stating "the powertrain control system has detected an electrical fault with the fuel pump and its associated wiring". The symptoms match those in 25V455 but this VIN number is not listed in the affected group.

The contact owns a 2021 Ford F-150. The contact stated that three months after purchasing the vehicle, while her husband was driving, the vehicle was driving roughly, and the transmission unexpectedly downshifted. The contact was unaware whether any warning lights illuminated. The vehicle was taken to the dealer, where it was diagnosed, and it was determined that there was a misfire in cylinders #1, #3, #4, and #6. The spark plugs were replaced, and the vehicle was repaired. The contact stated that on a separate occasion, a month after the repair, there was an abnormal sound coming from the steering wheel. The vehicle was taken back to the dealer, where it was diagnosed that the wheel bearing and axle had failed and needed to be replaced. The vehicle remained at the dealer unrepaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 56,000.

24E08 for catalytic converter. Ford has a customer service program for other VINs. This is not included. This is a widespread failure based on forms I have read across various year. I have 95k miles and have owned for 4.5 years. They also stated the PCM software needs to be updated related to the catalytic converter. This is about a 3k repair. 24E04 covers this exact issue, but my VIN was on included.

I have a safety recall notice 24S55 / NHTSA recall 24V635 on my F-150. Ford requires 2-3 days to diagnose the problem due to current workload. During this diagnostic period, Ford refuses to provide a rental or loaner, leaving me without transportation. I use the truck for work, so I do not have a way to take the truck in for the recall without coming out of pocket for a replacement vehicle. My understanding is that this is a gray area, as Ford has not issued instructions to stop driving, so are not legally required to provide a rental vehicle during the diagnostic period. The fact remains I would have to take a financial loss to bring my vehicle in for this recall due to the diagnostic time. A simple solution would be for Ford to provide a replacement vehicle during this time. I discussed this with the dealership and the corporate number, to no avail.

I had driven the car about 15 residential miles to Home Depot and back. As I was driving into my driveway I smelled smoke and looked forward to see a puff of smoke coming out from the front, driver's side wheel well. I put the car in park and pulled the hook release control under the steering wheel. Suddenly flames were coming out the sides of the hood, about 12" high. I pulled the car quickly away from the house and trees. Put the car in park, as the flames were now engulfing the entire hood. I quickly got away from the car and called 911. The Fire Department is close to my house, yet by the time they arrived the car, including interior cabin, was fully engulfed in flames.

Power steering rack failure, while driving though a puddle less than 6 inches deep. Cost over $1900 to replace. My wife's 2014 volkswagen passat is able to drive though deeper water.. on 8/13 I was unable to move over on a road that had some puddles due to oncoming traffic. After driving though the small puddle my power steering went out. Took to the mechanic and he said its a known issue due to how Ford did not seal their wiring well under the trucks and it hangs lower allowing the water to seep into the cables and cause the powering steering rack to fail.. this is unacceptable its a truck a puddle should not cause a truck to loose power steering.
