NHTSA #18V63100014/09/2018Component: SUSPENSION:FRONT:CONTROL ARM

Mazda North American Operations (Mazda) is recalling certain 2009-2010 Mazda Mazda6 vehicles sold, or ever registered in Connecticut, Delaware, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, Virginia, West Virginia, Wisconsin and the District of Columbia. The front cross member may corrode after exposure to road salt.

Consequence

Corrosion may weaken the mounting point for the passenger side lower control arm, unexpectedly changing the steering alignment and increasing the risk of a crash.

Remedy

Mazda will notify owners, and dealers will inspect the cross member and either install a side member and drain hose and apply wax to protect from rust, or install a drain hose and an improved front cross member, free of charge. The recall began March 18, 2019. Owners may contact Mazda customer service at 1-800-222-5500 Option 4. Mazda's number for this recall is 2818I.

Remedy

Owners are advised not to drive their vehicles until the repair has been performed. Mazda will notify owners, and dealers will replace the front passenger air bag inflator with an alternate one, free of charge. The recall began December 3, 2019.
