NHTSA owner complaints file, dated Nov 11, 2026. Counted by complaint number, so a complaint naming three components counts once in the total.
NHTSA investigations file, dated Nov 12, 2026. Defect petitions, which ask NHTSA to open an investigation, are listed apart and only while open. Audit queries, which check whether a company met its recall and reporting duties rather than whether a vehicle has a problem, are not listed.
