Remedy Mazda will notify owners, and dealers will check the parking brake actuator shafts, replacing any that are corroded, free of charge. Remedy parts are currently unavailable.

Summary Mazda North American Operations (Mazda) is recalling certain model year 2014-2015 Mazda6 vehicles manufactured October 25, 2012, to October 10, 2014. If the pressures of four of the tires on an affected vehicle gradually drop at the same time, the tire pressure monitoring system (TPMS) may not warn the driver of the drop in pressure. As such, these vehicles fail to comply with the requirements of the Federal Motor Vehicle Safety Standard (FMVSS) No. 138, "Tire Pressure Monitoring System."
Remedy Mazda will notify owners, and dealers will update the TPMS software, free of charge. The recall began on December 10, 2014. Owners may contact Mazda customer service at 1-800-222-5500.
