Air bags:frontal:passenger side:inflator moduleDo not driveOct 12, 2018 · NHTSA campaign 18V717000 · 155,436 vehicles

Problem: Mazda North American Operations (Mazda) is recalling certain 2014-2015 Mazda CX-9 vehicles sold, or ever registered in the states of Alabama, California, Florida, Georgia, Hawaii, Louisiana, Mississippi, South Carolina, Texas, Puerto Rico, American Samoa, Guam, the Northern Mariana Islands (Saipan), and the U.S. Virgin Islands or "Zone A." Additionally, unless covered in "Zone A," Mazda is recalling certain 2011-2013 Mazda6, 2011-2012 CX-7, and 2011-2015 CX-9 sold, or ever registered in the states of Arizona, Arkansas, Delaware, Illinois, Indiana, Kansas, Kentucky, Maryland, Missouri, Nebraska, Nevada, New Jersey, New Mexico, North Carolina, Ohio, Oklahoma, Pennsylvania, Tennessee, Virginia, West Virginia and the District of Columbia, or "Zone B." Additionally, unless covered in Zone A or Zone B, Mazda is recalling certain 2010-2013 Mazda6, 2010-2012 CX-7, and 2010-2015 CX-9 vehicles ever registered in the states of Alaska, Colorado, Connecticut, Idaho, Iowa, Maine, Massachusetts, Michigan, Minnesota, Montana, New Hampshire, New York, North Dakota, Oregon, Rhode Island, South Dakota, Utah, Vermont, Washington, Wisconsin, and Wyoming or "Zone C." These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

Fix: Mazda will notify owners, and dealers will replace the front passenger air bag inflator with an alternate inflator, free of charge. The recall began November 9, 2018. Owners may contact Mazda customer service at 1-800-222-5500, Option 4. Mazda's number for this recall is 1317F.

Problem: Mazda North American Operations (Mazda) is recalling certain model year 2016 CX-3 vehicles manufactured June 1, 2015, to December 2, 2015, 2013-2014 Mazda2 vehicles manufactured July 3, 2013, to August 8, 2014, 2014-2016 CX-5 vehicles manufactured January 19, 2013, to December 2, 2015, and 2013-2015 CX-9 vehicles manufactured December 6, 2012, to July 31, 2015. The lower mounting nuts and bolts that attach the front strut assembly to the steering knuckle may loosen, allowing the steering knuckle to separate.

Risk: If the steering knuckle separates from the strut assembly, it can cause a loss of steering control, increasing the risk of a crash.

Fix: Mazda will notify owners, and dealers will inspect the lower mounting nuts and bolts that secure the front strut assembly to the steering knuckle. If the bolts are loose, they will be replaced and then correctly tightened, free of charge. The recall is expected to begin May 20, 2016. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 9316D.
