I've had my HiHy for about two months now and very satisfied with it. I have noticed that after turning the car off after running the A/C, that a number of different sounds may start to occur. I know that some of this is pretty typical due to the pressure equalizing within the system, but this seems different due to be the variety of noises that occur, from whistling to even a buzzing sound. Is this typical? Thanks!

 

I don't hear any strange noises after running the A/C, and I have run it both hard and long on the highway as well around town.

If you could describe the noise and the circumstances I will make an effort to duplicate your use and listen really close.

 

I have heard the noises make a lot of different times, although it seems to be when it is really hot outside. I am going to the dealer in a few days for my first check up and will mention it to them. I figured that maybe it was jsut one of those ehybrid things since the compressor is electric driven rather than driven off a belt. Will let you know what they say. Thanks.
