## What is wrong

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.


## What can happen

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.


## The 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.
