It's not "if" you're going to have gauge problems; it's "when" :-)
Most problems can be traced back to the contacts on the printed circuit at the back of the gauge panel; I'd advise pulling the pod, cleaning up the contacts (pencil eraser works great), replacing bad bulbs, check grounds at steering support...etc. I believe the printed circuit is still available new if your's is bad.
