Vehicles Affected: Approximately 228,000 model-year 2014-16 Mazda3 cars and model-year 2014-15 Mazda6 sedans
The Problem: Water could enter the brake caliper, causing the parking brake actuator shaft to corrode and possibly bind, which may prevent the parking brake from engaging or disengaging fully. This could allow the vehicle to move unexpectedly when parked on a slope, increasing the risk of a crash.
The Fix: Dealers will check the parking brake actuator shafts and replace any that are corroded for free.
