Does your compass work correctly? I set mine to the correct region number and it was still not correct. I have tried the calibration mode, the DIC tells you to drive in circles. I find this a little strange as I wouldn't think the compass would be that difficult to calibrate.
 
I am reasonbly satisfied with the car to date, it certainly rides and handles much better than the SUV I traded in.

axi,
  Driving in circles to calibrate the compass is normal, in my experience. I can't speak to other makes but it has been a requirement in the cars I've owned.
  What exactly is your issue? Is the compass not working at all or just seem to giving erroneous headings as you drive? Be sure to calibrate it in an area with no interference...preferrably a place with no light poles or away from buildings.
  Mine works like a champ although I don't expect perfection. After all, it's only giving general heading not a specifice degree readout. Let us know how it works out for you.

The directional readings were erroneous, It is now calibrated, driving around cloverleaf interstate interchanges must qualify as "driving in a circle', that is where it was finally calibrated.
 
I do need to check the headings.

axi,
  Keep in mind that the calibration feature will eventually stop bugging you to calibrate and will eventually return to giving the general direction based on the calibration it could achieve through your routine driving. However, it wouldn't be fair to judge the system if you haven't taken the time to properly set it up. The recommended calibration only takes a minute or less (literally) and will then give you a much more accurate reading. The only real issue with doing it is that you make look a little silly driving in circles. The folks working in the establishment who's parking lot I used were looking at me funny through the windows. But, I just drove away afterwards so no harm done.
 
Good luck!
Ron

I bought a new vehicle about a month ago, and I'd set up the proper zone on the built-in compass, but had never taken the time to calibrate it properly. Yesterday afternoon we were driving through a neighborhood looking for houses for sale, and wound up on a cul-de-sac...PERFECT time to stop and calibrate the compass! Sure I made an extra loop around the circle, but now it's done.

Cul-de-sacs are also a very good option as there will likely be less interference in a residential neighborhood. However, there is a higher chance of odd looks coming from the residents.

I had a hard time calibrating because of overhead wires. Finally found a field by my barn and it calibrated in short order. Seems accurate since. Have been on a long trip, 28-30 mpg, runs great. Enjoy the ride.

I did get my compass calibrated. I set the correct zone first, then pressed the check to calibrate the compass. It took five or six circles in an empty parking lot, The directions appear to be correct.
 
I am getting about 27 mpg for my 70 mile a day round trip commute which is mostly interstate highway driving through the city. Trafficwise some days are better that others. The worst mileage I have seen so far is about 23 mpg on stop and go in town driving. I am very happy with the gas mileage, this is one of the reasons I selected this particular car. I have the 3.5, 211 HP V-6 engine.

When I have the heat on there is an intermittent ticking noise that comes from somewhere in the dash. Anyone else have this issue?

There was a TSB for the '06 model's dash ticking but it was due to dash clips rubbing against the windshield. I believe that problem was fixed in the mid-06 run. Does it continue indefinitely or seem to calm down after the car has warmed up?
 
As for your '08 model, is it loud (like a rock hitting the windshield) or fairly minor? My guess is you're hearing the different components "creaking" against each other as the temperatures equalize. This is basically the same thing that was happening with the early '06s but the noise was louder due to metal rubbing against glass. I think it's just plastic on plastic in your case.
