For the engine , check for trouble codes. Have the spark plugs checked. Check throttle position sensor.

For the transmission, an error has been detected and the transmission is in limp mode, meaning the transmission is locked in 3rd gear when it is moving and if you strain the transmission, you are going to damage. You need to retrieve the trouble code to know what is causing the problem, usually a faulty solenoid or sensor or their wiring.

There Kia has their factory scan tools and there are generic scan tools that do have the capabilities.
