I have had the same issue since getting mine. Dealership tried and update at first scheduled maintenance, but still problem continues.So your drivers display is the full digital one w/analog speedo and tach? If so, haven't seen anyone on these forums mention this before. Must be unique to your car. Sounds like a possible loose connection? But that's a safety issue. Call Kia CS, tell them dealer can't fix and you are going to file a complaint w/NHTSA:

Wow. Thanks for this, JRo! I also have the trailer harness installed (who would have thunk it!?), so know what to look for now if this happens.Just got a call from my dealership and Kia reached out to them and there is recall in progress for our issue. It is the factory trailer harness that is causing the screen to short out and reboot. They believe the trailer hitch control module needs to be replaced but are working through it right now. I would reach out to your dealerships and ask them to start a conversation with Kia, then as soon as they 100% have a solution you can get it fixed right off. Woooohoooo FINALLY!!!
