Mazda is recalling approximately 228,000 2014-2016 Mazda3 cars and 2014 and 2015 Mazda6 sedans because they may have faulty hand-operated parking brakes that could fail.
NHTSA recall documents report that water could leak into the brake caliper, causing the parking brake actuator shaft to corrode and possibly bind, which could prevent the parking brake from engaging or disengaging all the way. This could result in a crash.
This issue dates back to 2015 when Mazda received eight reports of brake issues in the U.S, along with one in Canada. That number has now grown to 13 incidents in the United States.
Mazda says it is addressing the problem with a new sealing design that improves protection of the brake caliper protective boot.
The automaker will begin contacting owners Aug. 21. Dealers will check the parking brake actuator shafts and replace any that are corroded at no charge.
Owners can call Mazda at 800-222-5500, or the NHTSA hotline at 888-327-4236.
