Mazda North America is recalling over 307,000 cars to address an issue with the handbrake.
The action affects Mazda6s from 2004 and 2015, and Mazda3 models from 2014-2017, but only those models with the actual handbrake, which may not release fully after it’s pulled up and could result in binding during driving, or may not engage fully and allow the car to roll away.
The issue first came to light in Canada in 2015, arising from water seeping into the rear brake caliper and causing the parking brake actuator shaft to corrode to the point of binding the cable, perhaps not allowing the brake to engage or disengage fully.
The recall affects 227,814 in the US, 72,835 in Canada and about 7,000 in US federalized territories.
Owners will be notified in mid-August to bring their cars to Mazda dealerships to have the rear brakes checked for corrosion in the calipers. If there is corrosion in the actuator shaft, the entire caliper will be replaced; if there isn’t, dealers will replace the rubber boot meant to keep water out of the actuator shaft.
Mazda is aware of at least 13 problems in North America associated with the issue, but is not aware of any injuries, although there have been reports from Europe of damage from vehicles rolling away when the parking brake was engaged.
