Ford preliminary evaluation PE22007
Loss of motive power due to valve intake failure on Ford Bronco vehicles.. NHTSA’s Office of Defects Investigation opened this preliminary evaluation about the engine on 1 model year (2021). Opened Jul 22, 2022, closed Oct 2, 2023 after 14 months without a recall. closed
What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Defects Investigation (ODI) received a petition dated March 16, 2022, requesting an investigation regarding allegations of defective intake valves in model year (MY) 2021 Ford Bronco vehicles equipped with the 2.7L Eco-boost (“Nano�) engines. The petitioner alleged these vehicles are experiencing loss of motive power at any highway speeds with no-restart as a result of catastrophic engine failures. To date ODI is aware of 42 submitted Vehicle Owner Questionnaires (VOQ’s) alleging a loss of motive power. On July 22, 2022, ODI opened a Preliminary Evaluation (PE22-007) to investigate allegations of stalling/loss of motive power on the subject vehicles. Upon receiving Ford’s Information Request (IR) response, ODI learned Ford was aware of 110 consumer complaints (including field reports), 125 warranty claims and 136 engine exchanges related to the 2021 Ford Bronco. Ford’s response indicated these failures are across the “Nano� engine family, which includes both the 2.7L and 3.0L EcoBoost engine variants with a total estimated population of 708,837 vehicles. Additionally, ODI became aware that the subject engines contained intake valves that were manufactured out of a specific alloy known as “Silchrome Lite�, which can become excessively hard and brittle if an over-temperature condition occurs during machining of the component. The overly brittle intake valve can fracture at the keeper grove causing the intake valve to freely contact the piston, resulting in catastrophic engine failure. A design modification was implemented in October 2021, which changed the intake valve material to a different alloy known as “Silchrome 1�, that is less susceptible to over-temperature during machine grinding. ODI is upgrading this PE to an Engineering Analysis (EA23-002) to better understand the failure mechanism identified by Ford and to ascertain the complete scope. To review the reports cited in the attached Closing Resume ODI Report Identification Number document, go to NHTSA.gov
A Preliminary Evaluation is the first formal stage: NHTSA has decided the complaints and other information it screened are worth a closer look, and asks the manufacturer for its own data on the condition. The summary is the agency’s own text from its investigation file, unedited; the opening and closing resumes with the full reasoning are on NHTSA’s site under this number.
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 closed without a recall. That means NHTSA found no defect trend it chose to act on at the time, or the manufacturer addressed the condition another way (a service campaign or a bulletin, which have their own pages). A closed file can be reopened if new reports arrive.

Common questions
Source: NHTSA Office of Defects InvestigationIs PE22007 a recall?
No. A preliminary evaluation is NHTSA asking questions, not a recall. A safety recall carries an NHTSA campaign number and a duty to repair for free; this one closed without one. Whether one particular vehicle has an open recall is a VIN question at nhtsa.gov/recalls.
Is PE22007 still open?
No. It closed on Oct 2, 2023 without a recall.
Which vehicles does PE22007 cover?
NHTSA opened it on 1 model year: 2021 Ford Bronco. That is the scope of the inquiry, not a list of affected vehicles; a recall, if one follows, defines its own population by VIN.
