VIN Decoder: Open Safety Investigations & Recalls

A recall is the end of a process. Before it there is an investigation — NHTSA has opened a file on a suspected defect and has not yet decided.

Every VIN tool answers "any recalls?". None of them answers "is this model under investigation right now?" — and that is the question a recall search silently returns no to.

The problem, with real examples

Run a recall check on a 2013 Honda Odyssey today and you learn nothing about DP26005, Inadvertent Deployment of Air Bags, opened 13 July 2026 and still open with no recall issued.

A 2018 Tesla Model 3 has several open investigations and no recall for any of them, including FSD Collisions in Reduced Roadway Visibility Conditions and Sudden Unintended Acceleration.

A 2014 Range Rover has EA26003, Front Steering Knuckle Fractures, open since April 2026. A 2022 Rivian R1T has PE26004, Rear Toe Link May Separate.

All four report clean on a recall-only check.

What this Actor does

For each VIN it decodes the vehicle and then reconciles four NHTSA sources:

Source	What it answers
vPIC	What the vehicle is — make, model, year, body, engine, plant, driver-assistance systems
Recalls API	Which recall campaigns cover this make, model and year
ODI investigation history	Which defect investigations are open, and whether any produced a recall
Complaints & NCAP	Owner complaint volume by component, and crash test ratings

No API key is needed for any of them, and nothing is scraped.

The checks

Code	Severity	What it means
open_investigation_no_recall	high	NHTSA is investigating a suspected defect on this model year and no recall exists. A recall search reports nothing here.
open_investigation_with_recall	medium	An open investigation that has already produced campaigns. Open means the agency has not finished.
recall_campaigns_for_model_year	medium	Campaigns cover this model year — see the honesty note below.
check_digit_failed	medium	The VIN fails its own check digit. Almost always a transcription error.
model_year_mismatch	medium	Position 10 of the VIN and NHTSA's decode disagree.
open_investigation_related_variant	low	An open investigation covers a related trim rather than this exact model.
complaint_cluster_without_action	low	Complaints concentrate on one component with no recall or investigation. This Actor's inference, not NHTSA's finding.

What it deliberately does not claim

It never says a recall is outstanding on your specific car. NHTSA's public API answers at make/model/year granularity; the VIN-level lookup on its website is not exposed as an API (/recalls/vin/<VIN> returns 403 — the route does not exist). A car may sit outside the affected production range, or have had the work done years ago. So the field is named recallCampaignsForModelYear, the output carries vinLevelRecallStatusAvailable: false, and the message tells you to confirm with the manufacturer. Tools that print "your VIN has 3 open recalls" from this same data are overstating it.

An open investigation is NHTSA's record; a complaint cluster is a pattern this Actor read. They get different severities and different wording.

A healthy vehicle produces no findings. If there is nothing open, nothing recalled and no unusual complaint concentration, the row comes back silent. A report where everything is flagged is a report nobody reads.

The check digit is only checked where the standard requires one. Vehicles built outside North America are not required to carry a valid one, and many do not — flagging those would put a warning on a large share of ordinary imports.

If the investigation file could not be read, the status is unknown, never clear. Absence of a finding is not evidence of absence.

Input

{
  "vins": ["5FNRL5H66DB000001", "5YJ3E1EAXJF006588"],
  "checkInvestigations": true,
  "includeComplaints": true
}

Output

One row per VIN. The fields that carry the verdict:

Field	Values
safetyStatus	open_investigation · investigation_in_progress · recalls_to_verify · nothing_outstanding · unknown
openInvestigationsWithoutRecall	Count of open investigations that produced no recall
investigations[]	{ investigationId, subject, component, opened, closed, isOpen, recallIssued, linkedRecallCampaigns }
recallCampaignsForModelYear	Campaign count for the model year, not for this VIN
issues[]	{ code, severity, message, evidence }
highestSeverity	high · medium · low · ok

Alongside them: the full decode (make, model, year, trim, body, engine, drive, fuel, plant, GVWR, driver-assistance systems), checkDigitValid, complaintCount with crashes, fires, injuries and deaths reported, complaintTopComponents, and safetyRatings.

Three key-value records are written as well: SUMMARY, OPEN_INVESTIGATIONS (the vehicles with something open and no recall) and NEEDS_ATTENTION.

How it stays cheap

Only the decode is per-VIN. Recalls, investigations, complaints and ratings are all model-level, so a fleet of two hundred identical vans is one safety lookup, not two hundred. The investigation history is a single 2 MB download for the whole run.

Limits, stated plainly

• US market only. These are NHTSA datasets.
• Investigations are matched on make, model and model year, which is the granularity NHTSA publishes. A trim-specific defect on a variant is reported separately rather than merged.
• The investigation file is point-in-time. It is refreshed periodically; an investigation opened this week may not be in it yet.
• Of the 5,338 investigations in the file, 4,060 name a specific vehicle — the rest are equipment and tyre inquiries with the vehicle columns blank, and cannot be matched to a VIN. Within the 4,060, 118 are open and 94 have produced no recall.
• No VIN-level recall completion status exists publicly. See above.

This Actor reports what those sources say. It is not a safety certification, and it does not replace checking a specific VIN at nhtsa.gov/recalls before buying or dispatching a vehicle.
