Official sources only

DrivewayWalk live-fetches or links these URLs. We do not use Carfax, AutoCheck, paid VINCheck APIs, Reddit, or SEO blogs as facts. IIHS and state MVD sites are link-outs — we do not scrape them. Arizona MVD pages apply only when the walk’s sale state is Arizona.

1. 1

   NHTSA vPIC VIN decode

   https://vpic.nhtsa.dot.gov/api/

   No API key. DecodeVinValues returns year, make, model, body, engine, fuel, plant.

2. 2

   NHTSA recalls by year/make/model

   https://www.nhtsa.gov/nhtsa-datasets-and-apis

   GET recallsByVehicle only. Campaign-level for the model — not proof this VIN still has an open recall. We do not call /safetyIssues (it returned the wrong vehicles). VIN-specific unrepaired-recall APIs returned 403. NHTSA’s API is not for bulk VIN lookups; we cache 24h per VIN and fetch only for the walk in progress.

3. 3

   NHTSA VIN recall lookup

   https://www.nhtsa.gov/recalls

   The this-VIN confirmation. Deep-link with the VIN. Never claim “no open recalls” without a result from this page.

4. 4

   NHTSA complaints by vehicle

   https://api.nhtsa.gov/complaints/complaintsByVehicle

   Consumer complaints, not findings. We show top components and crash/fire/injury counts.

5. 5

   NHTSA 5-star safety ratings

   https://api.nhtsa.gov/SafetyRatings/

   Lookup by year/make/model, then VehicleId. Empty if NHTSA has no rating row.

6. 6

   EPA / DOE fuel economy (fueleconomy.gov)

   https://www.fueleconomy.gov/ws/rest/

   Accept: application/json. No VIN→MPG. Match year/make/model plus displacement/drive/fuel from vPIC; if several trims remain, show the combined-MPG range.

7. 7

   FTC Used Car Rule

8. 8

   FTC Buyers Guide

   https://www.ftc.gov/business-guidance/resources/buyers-guide

   As-Is vs warranty language for dealer lots.

12. 12

15. 15

    https://www.nhtsa.gov/hurricane-and-flood-damaged-vehicles

    Waterlines in trunk / glove box / under dash; air freshener masking mildew. Clean-title flood cars exist.

    DOT TIN date (49 CFR 574.5). Tread often discussed as 2/32 in. Makers often recommend replacement at 6–10 years. Not a legal expiration. We do not invent a state 2/32 statute.
