If you logout/login next to a shed with a vehicle inside, you will hear vehicle sounds such as the sound when you place a wheel on, or open door/hood/trunk. If it is a humvee, you will get the humvee sounds, and same for truck and other vehicles. This will give away if there is a vehicle nearby, including if there is one inside of a locked shed or other locked up, non-visible area, giving the player information about the environment that they should not get.

This can be exploited to inform a user if they want to raid a locked up shed/garage/etc.
