Bought the SUV when it was cold out, when summer rolled around and I started using the AC and I started hearing what would best be described as a clown whistle noise. I took it to the dealer I bought it from and described the noise. After having if for almost a week they claimed it was fixed. When I picked it up they had used up a full tank of gas (25 gals!!!) while idling the vehicle trying to identify the noise. That was annoying, at the time that was $100 in gas! On the short drive home it made the clown whistle noise. So it went back the following day. This time they had it for 2 weeks, only after the 1st week was I able to get a rental. While taking the compressor apart they said something broke. My suspicion is it that the part that was always broken, and it what was causing the noise. Had to wait a few more days to get the part in, but it fixed the problem.
