Decode Vehicle Identification Numbers to extract make, model, year, body type, engine, manufacturing details, and safety equipment: airbags, stability and braking systems, tire pressure monitoring, and the driver-assistance features VPIC records for the configuration, such as automatic emergency braking, lane keeping, blind spot warning, backup camera, and adaptive cruise control. Pass one VIN, or several as an array or in one string separated by spaces, semicolons, or commas. Partial VINs are accepted, with * for unknown positions; send each partial VIN as its own string or array entry. A call decodes up to 50 VINs; VINs past the first 50 come back in deferredVins to pass back as vin.

Get NCAP crash test ratings and ADAS feature availability for a vehicle. Use when the user specifically wants crash test stars, rollover risk, or wants to compare safety features across vehicles. NCAP data available from 1990+, best coverage for 2011+.

Get a comprehensive safety profile for a vehicle. Combines NCAP crash test ratings, recalls, and complaint summary into a single response. Use as the default when asked about vehicle safety, reliability, or purchase decisions.

Look up makes, models, vehicle types, and manufacturer details in NHTSA's VPIC catalog, or list the model names NHTSA's datasets file a make and model year under. VPIC names often differ from the names complaints and NCAP ratings use (Silverado vs SILVERADO 1500), and a vehicle's recalls can be split between a series name and a base name. When a recall, complaint, or rating search comes back empty or partial, call operation="dataset_models" with make and modelYear, then search under each name it lists. No list enumerates recall names, so search recalls under both the series name and the base name.

Search consumer safety complaints filed with NHTSA for a specific vehicle. Returns a component breakdown over all matching complaints plus a paginated slice of the most recent complaints. Use for common problems, failure patterns, or owner-reported issues.

Search NHTSA defect investigations — Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), Recall Queries (RQ), Audit Queries (AQ), and additional ODI types — newest-opened first. make, model, and modelYear match the investigation's vehicle associations, all on the same association; component matches its affected components. All filters are ANDed. Search rows leave out the full summary unless includeSummary is true. Use nhtsaId to fetch one investigation by its exact ID with its full summary — including the investigationId nhtsa_search_recalls returns for a campaign. recallCampaigns lists the recall campaigns NHTSA links to an investigation; pass any to nhtsa_search_recalls as campaignNumber.

Search recall campaigns by campaign number, by vehicle, or across every campaign by make, model, model year, and received date. campaignNumber returns that campaign with every vehicle it covers; make, model, and modelYear together return that vehicle's recalls; any other combination of make, model, modelYear, and dateRange is a broad search of NHTSA's recall files, newest first, paged with limit and offset. A broad search matches a campaign when one of its vehicle records carries every vehicle filter given, and the received date it reports can fall one day before the date the other modes report for the same campaign.
