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.

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.

This happened a second time, but didn't shut off completely, it just felt like I was running out gas (full tank).

EA23002 · Loss Of Motive Power

Opened Sep 29, 2023 · Closed Oct 31, 2024

Status: closed (inferred from source dates) · Engine

On July 22, 2022, the Office of Defects Investigation (ODI) granted a Defect Petition (DP22001) and opened a Preliminary Evaluation (PE22007) to investigate allegations of loss of motive power in model year (MY) 2021 Ford Bronco vehicles equipped with 2.7L EcoBoost engines. Complainants were reporting sudden engine failure while driving resulting in a loss of motive power, often without the ability to restart. During PE22007, the cause of engine failure and loss of motive power in the subject vehicles was determined to be intake valve fracture, and the full scope of vehicles affected by the subject defect was identified as all MY 2021-2022 Ford and Lincoln models equipped with either the 2.7L or 3.0L EcoBoost engines, referred to as the “Nano” engine family.  If an intake valve fractures in the subject engines, it may drop into the cylinder and contact the piston, often resulting in catastrophic engine damage. On September 29, 2023, PE22007 was upgraded to an Engineering Analysis (EA23002) to further investigate the subject defect across the full scope of affected vehicles. During EA23002, ODI visited Ford facilities to review technical information related to intake valve fracture in “Nano” engines, coordinated with NHTSA’s Vehicle Research and Testing Center (VRTC), and analyzed updated field data relating the subject defect. Forensic analysis of fractured intake valves demonstrated that the defective components exhibited “grinding burn” or out of specification hardness in the area of the keeper grooves. The presence of grinding burn is evidence that during the groove grinding phase of production, the temperature of the valve became sufficiently high to alter the microstructure of the material and is indicative that the valve supplier’s manufacturing processes were not within control specifications. Grinding burn results in a hard, brittle microstructure and high residual stresses toward the surface of the valve. Through normal engine loading, a valve with grinding burn will likely fracture at the area of highest vulnerability, which is the third keeper groove. In its response to the EA23002 Information Request (IR) letter, Ford provided evidence of 396 customer complaints (including field reports), 825 warranty claims, and 936 engine exchanges. When considering both ODI and manufacturer failure report data, there have been reports representing 1066 unique vehicles within the subject vehicle population. Analysis of the failure report data demonstrates that vehicles equipped with potentially defective intake valves were built within a production “spike period” of May 2021 – October 2021. The beginning of the spike period corresponds to a ramp up in production at the valve supplier manufacturing facility, and the end of the spike period aligns with the implementation of several mid-production process improvements and the decision to change the metal alloy used to produce intake valves from “Silchrome Lite” to “Silchrome 1”. Ford began investigating the subject defect in July 2021, determined the root cause, and took corrective measures for the new production vehicles. Analysis of the failure report data demonstrates that these corrective actions were successful in eliminating the risk of intake valve fracture for subject vehicles produced after October 2021. However, Ford did not take any field action to address vehicles produced during the spike period, and in the several months following the implementation of the production changes, a significant number of field failures continued to occur. It is Ford’s assessment that not all valves produced during the spike period are defective, and that failures associated with the subject defect occur at low time in service. Analysis of the failure report data demonstrates that the vast majority of failures have occurred before 20,000 miles with over half of all reported failures occurring before 5,000 miles. The rate of reported failures related to the subject defect has steadily decreased since November 2021. ODI coordinated with NHTSA’s National Center for Statistics and Analysis (NCSA) to conduct statistical analysis and predict the number of future failures associated with the subject defect. The results of this analysis, and the trends identified through the failure report data are generally consistent with Ford’s assessment that defective intake valves will likely fail at a low time in service and indicate that the majority of subject vehicles equipped with defective valves have already experienced a failure. On August 23, 2024, Ford submitted recall 24V635 for subject vehicles equipped with “Nano” engines and built within the production spike period identified above (total population 90,736 vehicles). The remedy includes an inspection at a Ford/Lincoln dealership where the lifetime engine cycles of the vehicle will be determined. If a vehicle does not meet a threshold for lifetime engine cycles, the dealership will conduct a high RPM engine cycle accumulation procedure, which aims to identify if the vehicle is equipped with defective intake valves. Any vehicle that fails the accumulation procedure will receive an engine replacement under the recall. In addition to recall 24V635, Ford has stated that it will launch customer satisfaction campaign 24N12, which will provide extended warranty coverage to the subject vehicles through the earlier of 10 years or 150,000 miles. In view of the recall action being taken by Ford, ODI is closing this Engineering Analysis.
