Neither USB port is charging. I tried different cords

is the vehicle on?

Mine has given a little trouble that way once or twice, shutting it off for a good 5 minutes and restarting it has always taken care of the issue the two times it has ever happened.

I've tried different cords, phones and nothing. I can play music through the aux cord, but that's it.

might be time to take it to the dealer then for warranty repair

Google for uconnect reset maybe, I believe it involves holding the two buttons in the volume and tuner knobs for ~30 seconds with the ignition in aux. mode or something like that. Pretty sure the USB ports have no fuse of their own, they as listed on the same 20 amp fuse as the radio so if the radio works it probably just needs a reset.
