8 tools

• search_vehicles

  Find model years in the WhichTrim catalogue by make, model and/or year. Returns each match with its Safety Signal grade, recall count and page URL. Use this first to get the vehicle id that the other tools take.

• get_vehicle

  The full published record for one model year: EPA fuel economy, NHTSA recalls, owner-complaint counts and the mileage at which owners reported problems, crash ratings, open investigations, service bulletins and the diagnostic trouble codes its record names.

• get_trims

  Every trim of one model year as the manufacturer's own press kit states it: name, powertrain, drivetrain and MSRP, each trim's headline specs, which equipment is standard on which trims, and the warranty. Pass `trim` for one trim's full specification sheet (engine, dimensions…

• check_recalls

  Every NHTSA recall campaign on file for one model year, with severity, park-outside and do-not-drive advisories and the reported completion rate. IMPORTANT: recalls apply to a build range, not to a model year, so this cannot establish whether one specific vehicle is affected…

• decode_vin

  Decode a 17-character VIN against NHTSA's vPIC database and join it to the WhichTrim record for that model year: year, make, model, engine, plant, plus the grade and recall campaigns on file.

• lookup_trouble_code

  What a diagnostic trouble code (P0420, U0100, …) means where the OBD-II standard defines it, and — the part no other source publishes — which vehicles' federal record actually names it: how many manufacturer service bulletins and owner complaints mention it, and on which model…

• lookup_bulletin

  A manufacturer service bulletin, service campaign, warranty extension or over-the-air notice by the number on the letter or the document (Hyundai 9D6, Kia SC199, '26-01-068H TSB', GM N262570770). Returns what NHTSA's summary says, the model years it names, every document filed…

• compare_vehicles

  Two model years side by side on the figures that decide most purchases: fuel economy or EV range, Safety Signal grade, recalls, complaints, crash rating and starting price where a press kit is on file.
