Mazda North American Operations (Mazda) is recalling certain 2011 Mazda2 and 2010-2011 Mazda3 and Mazdaspeed3 vehicles equipped with a manual seat lifter. In the affected vehicles, the seat height adjustment lifter links may break or detach from the seat frame and the seat angle may incline causing the driver to not be able to maintain an appropriate driving position.
If the driver cannot maintain an appropriate driving position, there is an increased risk of a crash.
Mazda will notify owners, and dealers will inspect the seat lifter links and install a reinforcement bracket to the lifter links, or replace the entire seat adjuster unit, free of charge. The recall began April 7, 2017. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 0917B.
