I have 2012 Kia Optima hybrid. The radio and the cigarette lighters were working fine. One day my radio stopped working(no power to the deck) does have power to the back of it coming through the fuse box. The cigarette lighters do not have any power either. The fuses are good and I tested they have power going through them and are not blown. Could it possibly be a ground wire somewhere behind the dash? Any help would be appreciated

Are you sure the fuses are good? Did you remove them, and visually inspect, as well as voltmeter test? The cigarrete lighter sockets are separately fused, so that's two fuses to check. The primary ground is also attached to the fuse block, but there are also frame grounds as well. Check the engine bay fuse box, if you haven't already.

I am going to have to find and check the frame ground because yes, I did do a voltmeter test and their is power all the way to the back of the radio and at the fuse box. I will try and find the frame ground to see if that works
