Well, I see you took the advice and posted in the Electronics side, so I'll post here as well.

Sounds like a Unified Meter problem. Kind of a common failure among those vehicles equipped them. But, a dealer is going to be able to tell if you have one or if you have the standard type of meter.

If it's the unified meter assembly, they're kind of pricey, so I hope you're still under warranty. Perhaps an extended warranty?
