Data sources & last checked dates
Static public-data snapshotThis page is built from stored public data. Data last updated records a content change; Last checked records the successful source check retained with this snapshot. A later unsuccessful request does not refresh these dates, and checks with unchanged data may be recorded only in the update run report. Safety ratings and recalls can change after collection. EPA supplies configuration and economy data. NHTSA vPIC identity confirmation is not included in this snapshot; the published vehicle identity comes from the validated EPA records.
