I have been dealing with Hyundai for this very issues for 3 years, every time I report it they come out with a different part that need to be replaced be the problems continues to appear. I have called Hyundai a dozen times about this, even went for lemon law lawsuit but nothing. I still have the problem. They have done everything recharge the Freon, replace compressor, replace expansion valve and they still unable to figure out the issue. I just file another complain with BBB Auto Line. let see what they say..
