nhtsa
nhtsa_decode_vin
Decode a Vehicle Identification Number to extract make, model, year, body type, engine, safety equipment, and manufacturing details. Pass a single 17-character VIN string, or an array of up to 50 VINs for batch decode. Partial VINs accepted — use * for unknown positions.
nhtsa_get_safety_ratings
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+.
nhtsa_get_vehicle_safety
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.
nhtsa_lookup_vehicles
Look up valid makes, models, and vehicle types in NHTSA's database. Use to resolve ambiguous vehicle names, find correct make/model spelling, or discover what models a manufacturer produces.
nhtsa_search_complaints
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.
nhtsa_search_investigations
Search NHTSA defect investigations from the ODI flat file — covering Preliminary Evaluations (PE), Engineering Analyses (EA), Defect Petitions (DP), Recall Queries (RQ), Audit Queries (AQ), and additional ODI types. make, model, and component are structured filters against the investigation record's vehicle associations. All filters are ANDed. Use nhtsaId to fetch one investigation by its exact ID — including the investigationId nhtsa_search_recalls returns for a campaign. Investigations may link to a resulting recall campaign via recallCampaign.
nhtsa_search_recalls
Search recall campaigns by vehicle or campaign number. Use for specific recall lookups, recall history for a vehicle, or looking up a known campaign number.
