I have an 11 70th Anv kk and when I start it up in the garage during the daytime, the information panel and U-connect go out. If I stop when I'm out in the sunlight and turn off the ignition and restart it, they work as normal. I don't know if this is an ignition switch issue or an issue with the information/U-connect units. Anybody have similar issues? I tried to search this but found nothing.

Could it be a night sensor thinking its nighttime when you are in the garage, and turning on your headlights, thus dimming your dash lights?
When this happens try backing out, then turn on/off your headlights.
