Old Sea Dog

I bought a 2011 Cruzs 1LT in 12/7/10. After having it for some time and done long trips with it I find it to be very comfortable to drive. It has a solid ride that reminds me a bigger cars. Mileage is very good in the thirties even with the a/c on. In fact it makes very little difference if the a/c is on or off. The only problem that I have found is that the outside temperature display seldom works. I exchanged email with the GM people and then had it tested at Power Chevrolet in Peoria, AZ and all they say is that the "AMBIENT TEMP SEEMED TO BE OPERTING AS DESIGNED" I can go for days without the temperature display changing from the temp displayed when I start the car in the mornings. Only if I get on a highway and go over 50mph does the display changes and gives me a reading. "Operating as designed" does not cut it with me. Obviously there is some serious problems with the design if it does work like it should. GM didn't make any offers to see if the problem could be fixed. Has anyone else have the same kind of experience? Please let me know.
