    Here's the sound recorded with my iphone standing next to the driver's side mirror:

    (In the audio, you'll hear me opening the door, "the sound", and closing the door; you might need to increase the volume to hear the sound better; I'm sure this is my PIP; otherwise a Kia Soul and that's a hamster?)

    Was just going to post the same question. Thanks.

    I had assumed it was the PIP's way of saying "Agggh - is it morning already? :yawn:."

    Dealers should hand out an audio CD with the cars hybrid only noises? If you though the brake booster made an odd sound when you first opened the door; I strongly recommend you stay inside the car for a few minutes after you turn off the car. The booster goes through a whole cycle of noises that if heard for the first time, may cause some concerns. However, they are perfectly normal. I was caught off-guard by the fact that when charging , the water pump for the inverter is always on. It makes sense now, but at first I wants expecting to hear the noise from the front of the car.
