My car has an intermittent crackling noise when changing gears from park to reverse, park to drive, and vice versa. It also starts squeaking (coming from the engine) when backing up. The crackling noise almost sounds like sparks. Does everyone have that issue in their generation 2 Prius? I was told by the service adviser that it was the brakes. I think it sounds like a bad issue, although I was told it was completely normal, and maybe they can clean something. Is this pretty commonplace? I find it annoying, because it sounds like something is off, even though it isn't. It has gotten worse into a jolting occasionally when going into reverse or drive. It almost jolts, although the car doesn't move forwards or backwards. It is strange.
