nhtsa_get_vehicle_safety

• Combines NCAP crash test ratings, recall history, and complaint summary in a single response
• Frontal crash, side crash, and rollover ratings per vehicle variant
• Complaint breakdown by component with crash, fire, injury, and death counts
• Returns sectionStatus plus warnings so upstream outages are not mistaken for a clean record

nhtsa_search_recalls

Search recall campaigns by vehicle or campaign number.

• Look up by make/model/year or by specific NHTSA campaign number
• Optional date range filtering (ISO 8601)
• Includes do-not-drive advisories, park-outside warnings, and OTA update availability

---

nhtsa_decode_vin

Decode Vehicle Identification Numbers for manufacturing and safety details.

• Single VIN or batch decode up to 50 VINs
• Partial VINs accepted — use * for unknown positions
