Safety recalls

2 campaigns issued by the manufacturer

• Service Brakes, Hydraulic · Foundation Components · Master Cylinder

  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.

• Steering · Column

  Kia Motors America (Kia) is recalling certain 2021-2022 Rio and Forte vehicles. A bolt in the steering column may not be secured properly, which can cause the steering column to detach from the steering rack and result in a loss of steering control.
