I remember reading of this happening to a number of people. Right half of speedo and left part of digital gauge on 2004 is dark.
Did the dealer cover this? If not, what did it cost to get fixed?
It seems like a Yes warranty should cover it. If not you may be in for a real PITA weekend. You can read about a turn signal indicator bulb change here. The bulb you want to change should be near it
