A TSB is a note the maker sends to dealers about a known fix. They are not recalls. We check the bulletins so we know what to look for:
Cold-start noise, drivability, and idle issues for this vehicle. We test for each.
Shift quality and transmission fluid updates. We drive every gear.
Locks, wipers, infotainment, and trim items. Small, but good to know.
Counts are pulled from NHTSA's public Manufacturer Communications file. Full bulletins stay with the maker — we use the summaries to guide the inspection.
