Defect
On certain vehicles, damage inside the antilock brake system (ABS) hydraulic control unit (HCU) could cause an increase in brake pedal travel and reduced braking.
Safety Risk
Reduced braking can cause extended stopping distances and increase the risk of a crash.
Remedy
Mazda will notify owners by mail and advise you to take your vehicle to a dealership to inspect the brake ABS HCU, and replace it if necessary.
