A/c does not cool properly. I have been to the dealer twice for this problem. First time vehicle was still under warranty. There is a TSB out on this problem and dealer insisted that a/c was cooling properly. Now that the vehicle is out of warranty, it still has the same a/c problem. The vehicle now needs a $175 a/c service, TSB still not performed. My vehicle met all the criteria to have this performed before my warranty ran out, and still does.
