Recalls (3)
PARKING BRAKE · Campaign 17V393000 · Jun 22, 2017
Defect: Mazda North American Operations (Mazda) is recalling certain 2014-2015 Mazda6 and 2014-2016 Mazda3 vehicles. Water could possibly enter the brake caliper causing the parking brake actuator shaft to corrode and possibly bind.
Consequence: If the parking brake actuator shaft binds, the parking brake may not engage or disengage fully. If the parking brake does not engage properly, the vehicle may move unexpectedly if it is parked on a slope, increasing the risk of a crash.
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. Interim notices informing owners of the safety risk were mailed August 24, 2017. Owners will receive a second notice when remedy parts become available. Owners may contact Mazda customer service at 1-800-222-5500. Mazda's number for this recall is 1217F.
TIRES:PRESSURE MONITORING AND REGULATING SYSTEMS · Campaign 14V675000 · Oct 27, 2014
Defect: 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."
Consequence: A vehicle that is driven with under inflated tires may experience a sudden tire failure, increasing the risk of a crash.
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.
ELECTRICAL SYSTEM:ALTERNATOR/GENERATOR/REGULATOR · Campaign 14V173000 · Apr 10, 2014
Defect: Mazda North America Operations (Mazda) is recalling certain model year 2014 Mazda3 vehicles manufactured June 12, 2013, through December 18, 2013, and model year 2014-2015 Mazda6 vehicles manufactured May 20, 2013, through December 4, 2013, and both equipped with a 2.5L engine and a regenerative engine braking system. When driving the affected vehicles in heavy rain or in deep puddles, the alternator belt may slip causing the Power Control module (PCM) to incorrectly assume failure of the charging system.
Consequence: Once the PCM assumes that the charging system has failed, the vehicle will stop charging and could result in poor acceleration, loss of steering assist and windshield wiper operation, and a possible engine stall, increasing the risk of a crash.
Remedy: Mazda will notify owners, and dealers will reprogram the PCM with updated software, free of charge. The recall began on May 19, 2014. Owners may contact Mazda at 1-800-222-5500. Mazda's number for this recall is 7314D.
