List new and updated NHTSA recalls, investigations and complaint-count changes that this service recorded from the daily NHTSA bulk-file comparison, newest first, filtered by make, model, model year, type (recall, investigation, complaint_count) or observed date. Each change has the NHTSA campaign or action number, the record date, a short summary and a source link. These are published records, not a prediction, safety rating or advice. The free tier returns at most 10 changes per call with no paging, paid plans up to 200 with cursors and a vehicle watchlist.
