Yep, several times. It always settles down and goes back to normal after a bit, I don't think it ever lasted more than 15 minutes or so. I just started driving and it resolved itself. I'm pretty sure every time I have had to reboot the instrument cluster this has happened (maybe 3 or 4 times in the last 2 months). Seems that the brightness is set to 11 and doesn't want to turn down right away.
