Over the past few weeks my instrument panel has been acting up on my 2007 RRS Supercharged, periodically going dead then coming back. Sometimes it occurs half a dozen times in a short drive. Sometimes it's not the whole panel. I tested the voltage of the battery - 12.4 with the engine off and 13.7 running. That's with an exterior temperature of about 0 degrees Celsius. Not confirmed, but I believe this happens less frequently on longer highway drives. It's only the instrument panel, no issues with the display, lights, etc. Any thoughts?
