Service Brakes, Hydraulic:foundation Components:master Cylinder 2021-12-01 · campaign 21V936000 · 87 vehicles
Defect: Kia Motors America (Kia) is recalling certain 2020-2021 Rio vehicles. The brake master cylinder may have been manufactured with sharp edges that can damage the inner oil seal, resulting in reduced braking performance.
Risk: Reduced braking performance can cause longer brake pedal travel or extend the distance required to stop the vehicle, increasing the risk of a crash.
Fix: Dealers will replace the brake master cylinder, free of charge. Owner notification letters were mailed January 11, 2022. Owners may contact Kia customer service at 1-800-333-4542. Kia's number for this recall SC223.
