## What is wrong

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.

## The remedy

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.
