I''ve had this intermitten problem since day 1. I've had the service dept look for the problem and they say they just dim and I can't see it. I've driven at night without the lighted numbers and can't tell what speed I'm going.
I took my car to the dealer and the guy gets on his knees and put his hand near the floor heater and said there is heat coming out of there. So as far as they are concerned there is no problem. SO my feet freeze
