My battery keeps dying

Hello, if you are still underneath the 3 year / 36,000 mile factory warranty, please make your way to your local Kia dealership to have your Rio evaluated under the terms of the warranty. If not, your battery could be the cause of failure -- you'll need to have it tested for charge and the ability to hold a load. If the battery passes, you'll need to check the rest of the starting and charging system.
