US Vehicle Technical Service Bulletin (TSB) Index — MY 2005–2025

One row per vehicle (year + make + model) with the number of NHTSA-collected technical service bulletins (TSBs) its manufacturer issued — the automaker's own dealer-facing documentation of a known condition and its fix — plus the component area most bulletined and, for comparison, the vehicle's owner-complaint and recall totals. A TSB is an acknowledgment of a known issue short of a recall; no other public source aggregates TSB counts into a downloadable per-vehicle table. Contents: 6,469 vehicles. Method: Built from NHTSA's technical service bulletin flat file (manufacturer-to-dealer communications NHTSA collects). "tsb_count" is the distinct bulletins mapped to that (year, make, model); "top_category" is the NHTSA component area with the most. A TSB documents a known condition and a repair procedure — it is NOT a recall, and bulletin types range from major driveability fixes to minor informational or warranty-extension notes (Service Bulletin/Repair Instructions, Service Campaign, Warranty Program/Extension, Emissions, Over-The-Air). A high count reflects DOCUMENTATION VOLUME, not severity, and partly tracks a model's sales volume and age. Dates are bulletin communication dates. complaint_count and recall_count come from the NHTSA owner-complaint and recall record, for context. Motorcycles excluded. NHTSA complaints are unverified consumer reports. Source: U.S. NHTSA owner complaints and recalls (public record), model years 2005–2025.
