Hello fellow members.
Just wanted to know if anyone notices the hissing sound when the sunroof is closed and the shade is open. It sounds like wind noise, but only occurs when you step on the accelerator. I have a GS3.
And also, what is that sound when you first start the car, sounds like something is being turn on and adjusting it self from the front. I do not have HID, so it can’t be the auto level. Any feedback will help.

Thanks.

have you tried pushing on the glass roof when accel and see if you still have the sound? if not, how about the sunshade?

and the sound you hear that's the brake fluid pumping

The sound that you hear when you start up is the VSC doing a self check.

Maybe the rubber seal around your sunroof is damaged (cut, torn, or hardened from sunlight exposure preventing it from sealing properly).
