Ford defect petition DP26011
Camshaft and Lifter Failure in Ford 7.3L Gasoline Engines. NHTSA’s Office of Defects Investigation opened this defect petition about the engine on 4 model years (2021–2022). Opened Oct 23, 2026 and still open — 12 days so far, against NHTSA’s goal of four months for a defect petition. open
What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) received a petition on June 13, 2026, requesting an investigation into camshaft and lifter failures in Ford 7.3L gasoline engines used in 2021-2022 Ford E-350 and 2021 Ford F59 and F-750 vehicles. The Petitioner alleges that insufficient oil lubrication at low idle (~6 psi) causes severe wear on lifter rollers and camshaft lobes, leading to catastrophic engine failure and sudden loss of motive power while driving at highway speeds with little to no warning. The petition further alleges that Ford Motor Company was aware of the root cause and released a software calibration patch raising idle speed to ~1,000 RPM, but failed to initiate a public safety recall or notify vehicle owners. The petition itself can be reviewed at NHTSA.gov under ODI number 11764421. This defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition.
A Defect Petition is a petition from a member of the public asking NHTSA to open a defect investigation; the agency grants or denies it and publishes the reasons. The summary is the agency’s own text from its investigation file, unedited; the resumes carrying the full reasoning are linked below.
The paperwork NHTSA filed
Source: every document on this action, at nhtsa.gov- Opening resume — ODI’s own summary of why it opened this — the subject, what prompted it, and the vehicles in scope.
These are NHTSA’s own files, served from the agency’s site — the resumes are what ODI wrote when it opened and closed the action, and the rest is the correspondence behind them, including what the manufacturer sent when the agency asked. They are linked, not copied: where a document names the people who wrote in, that redaction is the agency’s to make and its copy is the one you should read.
What owners had already reported
Source: complaints on file the day it openedWhen NHTSA opened this on Oct 23, 2026, owners had filed 57 complaints with the agency about the model years above, of which 15 named the engine NHTSA went on to investigate. Owner complaints are the agency’s main early signal, and more can be filed while an action is open.
This is what the complaint file held on that date, not a claim about which reports prompted the investigation — NHTSA’s complaint records carry no investigation number, so nobody can make that link from the data alone. The opening resume linked above names the reports ODI itself cited. Complaint records on this site begin with 2016.
What this means for an owner
Source: and what happens nextAn investigation is not a finding that a defect exists, and it puts no duty on anyone. NHTSA opens a Preliminary Evaluation when complaints and other reports suggest a condition worth asking the manufacturer about; it upgrades to an Engineering Analysis when the answers warrant testing; it closes either when it recommends a recall, when the manufacturer recalls on its own, or when no defect trend is found. The agency’s own goals are about four months for a petition, eight for a Preliminary Evaluation or a Recall Query and eighteen for an Engineering Analysis; many run longer.
This one is open. Nothing is owed on the vehicle today; if it becomes a recall, owners are written to and the repair is free. The moment to know is the day the campaign number appears — Recall Watch checks each VIN against every new NHTSA campaign and emails you when one lands, or take a free one-line alert by model year.
Model years it names
Source: as NHTSA filed themAlso named on model years this site has no page for: 2021 Ford F-59; 2021 Ford F-750.
A vehicle page’s investigation list carries the same action; a name here is the scope NHTSA opened, not a list of affected VINs.
An investigation is not a recall. Yet.
If NHTSA’s questions become a recall, the campaign lands in the federal file first. Recall Watch checks your VINs against every new campaign the night it is filed.
Common questions
Source: NHTSA Office of Defects InvestigationIs DP26011 a recall?
No. A defect petition is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one has not produced one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is DP26011 still open?
Yes, as of NHTSA’s latest file: opened Oct 23, 2026, 12 days ago.
Which vehicles does DP26011 cover?
NHTSA opened it on 4 model years: 2022 Ford E-Series, 2021 Ford E-Series, 2021 Ford F-59, 2021 Ford F-750. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
