what can the reasons for the speedometer to stop working on a 2010 Kia Rio LX

Hello, sounds like you may have a concern with the vehicle speed sensor, or the related wiring to the sensor. Have this tested.

Good Morning, I am from Ultimate Performance and it sounds possibly like your Instrument Cluster. What year is the vehicle. We are open from 7:30a to 5:30p. We can get this diagnosed for you and go from there. Thank You, Charisse
