The Model Name Alone Is Too Broad for Vehicle-Specific Advice Main conclusion Confirm the exact version before treating model-level advice as specific Multiple configurations are the usual pattern in the matched portion of this database: 2,336 of 2,608 model-years, or 89.6%. A model-year summary can therefore combine equipment from several possible versions. The summary helps identify what to verify; it does not identify the configuration of an individual vehicle. Analysis Why configuration matching changes the meaning of the advice The issue is applicability. A model name can organize research while still combining gasoline and hybrid versions, different drivetrains or other equipment. In the matched records, 745 model-years have multiple fuel categories and 1,537 have multiple drivetrain options. Those differences explain why advice about a particular system needs a more precise vehicle description. The groups overlap, and source configurations are not unique trim counts. A combined list of fuel and drivetrain options also does not prove that every possible pairing was sold. Constructing a car from that combined list can attach equipment or repair examples to a version that does not have them. Confirming the actual version resolves that question before the advice is used. A high match rate does not resolve the version question. EPA details are available for 95.1% of the 2,742 mapped model-years, but 89.6% of those matched records contain multiple configurations. The first percentage describes source coverage; the second describes how broad the matched information remains. Finding a source and identifying the individual car are separate steps. The 134 unmatched model-years introduce a separate information gap. Missing EPA details should remain unconfirmed rather than being borrowed from an adjacent year. The absence of a match cannot establish the absence of equipment or better reliability. Together, the findings support a practical rule: verify identity and source fit before drawing a vehicle-specific conclusion. Conclusion Research the version that will be owned Start with the actual year, engine, fuel type and drivetrain, then use manufacturer records or build information to confirm the details. Apply equipment-specific guides and coverage questions to that version. Where a source does not identify the version, treat it as background until its applicability can be checked. This is a conclusion about research fit, not a ranking of vehicles or a prediction of repairs. Suggested attributed interpretation: “In AutoWarranty's matched database, nearly nine in ten model-years contain multiple EPA source configurations. A model name organizes the research; the exact version determines which equipment-specific advice can apply.” Numeric finding quotation: “AutoWarranty's configuration audit leaves 134 of 2,742 model-years without an EPA match. Another 2,336 contain multiple configurations, making the model name alone too broad for an exact repair estimate.” Attribution: AutoWarranty.Autos analysis Population: 2,742 model-years joined to EPA and a public source index Snapshot: 2026-08-07 Published: 2026-09-04; analysis reviewed: 2026-10-12 Method - Join EPA by exact mapped make/model/year keys. Separate unmatched years from matched years with multiple configurations. - Use the existing normalized model-path matcher for FixCatalogue and count files within an exact indexed year. - Fuel and configuration counts overlap. Preserve one CSV row per site model-year so each group can be recomputed. - Audit the packaged snapshots. Live source coverage can change; new imports require review. Limits - EPA summaries are not exact VIN records or a determination of contract eligibility. - Link counts do not measure prevalence, severity or unique campaigns across years. - The FixCatalogue layer in this audit is its sitemap, not its complete database.
