What NHTSA says
Source: Office of Defects Investigation, as filedThe Office of Vehicle Safety Compliance (OVSC) has been evaluating a product marketed and sold by Evenflo Company, Inc. ("Evenflo") as a “Rotational All-in-One Convertible Car Seat,” under the model name “Revolve360,” based on concerns about the product’s compliance with the FMVSS for child restraint systems FMVSS No. 213 (49 C.F.R. § 571.213). The Revolve360 has a detachable base, which OVSC understands was used by Evenflo in certifying compliance with FMVSS No. 213. As documented in a test report, the Revolve360 appears not to comply with a number of FMVSS No. 213 requirements, including but not limited to the means of installation in S5.3.2 and labeling requirements in S5.5. Other similar Revolve360 products, which also use detachable bases, appear to pose the same issues with the FMVSS No. 213 requirements. Evenflo has continued to certify and offer the Revolve360 products for sale. NHTSA is aware of at least six crash incidents in the field during which the Revolve360’s shell, as referred to by Evenflo on the Revolve360’s printed instructions, reportedly separated from its detachable base. Further examination of Evenflo’s certification of the Revolve360 products as compliant with FMVSS No. 213 is necessary. Through this investigation, the agency will obtain additional information about the potential separation of the Revolve360’s shell from its detachable base to assist with the agency’s evaluation of these products.
A Audit Query is an audit of whether the manufacturer met its early-warning reporting obligations — the data and reports it must send NHTSA — rather than of a vehicle condition. The summary is the agency’s own text from its investigation file, unedited; the resumes carrying the full reasoning are linked below.

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 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 themNHTSA filed this action against Evenflo Company, Inc. without naming a model year — an equipment or manufacturer-level query.

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 AQ24001 a recall?
No. A audit query 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 AQ24001 still open?
Yes, as of NHTSA’s latest file: opened Jan 5, 2024, 2.8 years ago.
Which vehicles does AQ24001 cover?
NHTSA filed it against Evenflo Company, Inc. without naming a model year.
