Subaru VIN Decoder: 4 Common WMI Codes
Decode any Subaru VIN free: the first three characters (JF1, JF2, 4S3, 4S4) identify the assigned manufacturer and vehicle type, position 10 encodes the model year and position 11 commonly identifies the assembly plant. Then check that vehicle's recalls and history separately.
Run the exact 17-character VIN, compare the physical vehicle, and keep each history category separate.
A Subaru VIN check can verify the identity of a Subaru car, wagon, crossover, SUV, sports car, or EV and may return body, engine, drive, fuel, transmission, and restraint data. It cannot establish maintenance quality, off-road use, modifications, exact option packages, or mechanical condition.

The first three VIN characters identify the assigned manufacturer and vehicle type. These common World Manufacturer Identifier patterns were checked against NHTSA vPIC data, but a prefix alone does not prove final assembly country; confirm the complete VIN’s returned plant fields and vehicle-specific records.
| WMI | What it identifies |
|---|---|
| JF1 | Subaru passenger cars built in Japan (Subaru Corporation) |
| JF2 | Subaru SUVs and crossovers built in Japan |
| 4S3 | Subaru passenger cars built in the United States (Lafayette, Indiana) |
| 4S4 | Subaru SUVs built in the United States (Lafayette, Indiana) |
Where to find the VIN on a Subaru
Every Subaru shows its VIN on the federally required plate at the base of the windshield on the driver's side. You'll also find it on the certification label on the driver's-side door jamb, and Subaru stamps the number into the firewall at the rear of the engine bay. The same 17 characters appear on the title, registration, and insurance card.
Check Subaru warranty coverage by VIN
Subaru's factory coverage is a 3-year/36,000-mile basic limited warranty plus a 5-year/60,000-mile powertrain limited warranty, per Subaru's official Warranty & Maintenance booklet. Coverage is tracked by VIN and in-service date rather than by owner, so any Subaru retailer can look up exactly what remains on a specific car from its 17-digit VIN.
Subaru has built cars in the United States since September 1989, when Subaru of Indiana Automotive in Lafayette, Indiana assembled its first vehicles. US-built Subarus carry VINs beginning with 4S instead of the JF codes used on Japanese-built cars.
What to verify on a Subaru
- Verify body, engine, transmission, and drive fields rather than assuming all versions of a model share the same configuration.
- Inspect for suspension, wheel, tire, towing, or off-road modifications not represented in the VIN decode.
- For EVs, decoded identity is not a battery-health or charging-history report.
- Check the exact VIN through Subaru and NHTSA recall resources.
Among the five Subaru models with at least three model years of NHTSA complaint data (2015–2022), the Outback drew the most owner complaints per model year — a median of 725.5 across its eight model years with enough complaints to compare — a figure that tracks sales volume as much as reliability. The WRX drew the fewest, a median of 52 per model year. The BRZ has fewer than three model years with enough complaints on record and is not ranked. On recall campaigns the Outback leads, with 23 across the period. Medians per model year keep a model with more years on record from outranking one with fewer, but complaint counts still rise with sales volume and time on the road, so this orders models within one make rather than measuring build quality.
Which Subaru model year to avoid
Every Subaru model with several years on record, ranked year against year on NHTSA owner complaints and recall campaigns. The comparison is within one model only — a year is called out when it stands clear of that model’s other years.
Subaru recalls and reported problems by model year
Each page below reports the NHTSA safety recalls and owner complaints on record for one Subaru model year. Model-year data narrows where to look; only a VIN lookup tells you whether a specific vehicle still has open recall work.
Subaru VIN and buyer checklist
- Match VIN plates, labels, title, and service documents.
- Confirm engine, transmission, drive, and body details.
- Ask for modification, off-road, collision, and maintenance records.
- Check recalls and arrange a pre-purchase inspection.
What a Subaru VIN check cannot prove
- A VIN alone does not prove accident, title-brand, theft, lien, ownership, service, or complete mileage history.
- Decoded equipment can be incomplete or broad; confirm trim, options, and installed hardware on the vehicle and its documents.
- A “no open recalls” result is time-specific and is not a mechanical inspection or a promise that every past recall was completed correctly.

Subaru VIN check questions
What can a Subaru VIN tell me?
A valid 17-character Subaru VIN can identify the vehicle and may return manufacturer-submitted attributes such as model year, model, body class, engine, drive type, or restraint details. Returned fields vary, so compare them with the vehicle and title instead of treating every blank as a defect.
Can a VIN check confirm the exact Subaru trim and options?
Not always. NHTSA decoding can return useful factory identity data, but exact packages, optional equipment, and later modifications may require the original window sticker, build record, dealer documentation, or a physical inspection.
Does a Subaru VIN check include recall information?
VIN identity and recall status are separate checks. Use NHTSA’s recall lookup and Subaru’s official owner or recall resources, because recall status can change and some newly announced campaigns may not appear immediately.
What should I verify for this Subaru?
Match VIN plates, labels, title, and service documents. Confirm engine, transmission, drive, and body details. Ask for modification, off-road, collision, and maintenance records. Check recalls and arrange a pre-purchase inspection.
What does a Subaru VIN starting with JF1 mean?
JF1 identifies Subaru Corporation passenger cars and appears on Japan-built examples. Japan-built SUVs have used JF2, while Subarus assembled at the Lafayette, Indiana plant have used 4S3 and 4S4. A WMI alone does not prove assembly country; check the full VIN plant data. This is a common registered or decoded pattern, not standalone proof of final assembly; confirm the specific vehicle’s complete NHTSA plant fields and manufacturer records.
How do I check my Subaru's warranty by VIN?
Any Subaru retailer can look up remaining basic (3-year/36,000-mile) and powertrain (5-year/60,000-mile) coverage using the VIN and the vehicle's in-service date. A free VIN decoder confirms the model year, but only Subaru's own systems show the in-service date.
