What's wrong, in plain English
Kia is recalling certain Rio vehicles because the brake master cylinder may have been manufactured with sharp edges. Those edges can damage an inner oil seal inside the master cylinder. Once the seal is damaged, the brakes may not perform as well as they should, which can show up as a brake pedal that travels farther than normal or a longer distance needed to bring the vehicle to a stop.
What you should do
2. Contact Kia customer service at 1-800-333-4542 or your dealer to have the brake master cylinder inspected.
3. If replacement is needed, the repair is free of charge.
