Have any of you experience a quick clicking sound whenever you change the gear from park to drive, and from drive to park? I hear it when someone is driving my GS and I'm standing outside of the car. Or when I have my windows down.

 

is your auto parking brake on? thats the sound of it activating and de-activating.

 

No, I always have the auto parking brakes turned off.

 

If I'm changing as you describe with my driver's door open, yes I can hear a metallic clicking sound. Don't hear it inside the car....good thing they're so well insulated because they're actually quite noisy vehicles

 

Yes, also when I have my windows down and changing the gear.

 

I wouldn't lose any sleep over it.
