Campaigns naming each model year, as filed with NHTSA
This page lists every US recall campaign that named the Thor Motor Coach Aria for model year 2010 or later, as filed with NHTSA. It counts 4 campaigns. CarsMultiverse is an independent site, not an authority. The list was read from the NHTSA flat file FLAT_RCL_POST_2010.txt (file dated 10 September 2026) and this index was built on 11 September 2026. Each campaign links to the site's own page for it, where one exists, or to the notice at NHTSA.
