As NHTSA's recall record states it for campaign 16V594000.
Defect description
Mazda North American Operations (Mazda) is recalling certain model year 2009-2010 Mazda6 vehicles manufactured February 4, 2008, to December 3, 2009. The protective coating may not have been properly applied to the air bag control unit (ACU) and, as a result, moisture may damage the unit causing it to malfunction.
Safety consequence
Failure of the ACU would illuminate the air bag warning light and prevent the air bags from deploying in the event of a crash, increasing the risk of injury.
Manufacturer remedy
Mazda dealers will replace the ACU, free of charge, however parts are not currently available. The recall began June 2017. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 9816H.
Notes
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
