I have a 06 5/AT. After I release the parking break and put the car in Drive there is this weird sound almost like a buzzing fart sound once I drive a few feet. It only makes it one time for a split second. It happens every time. Has anybody experienced this or know what i'm talking about?

 

ABS self test. it does this once every time you start your car and it happens around 3-4 mph. Happens just once per drive cycle.

 

Thank god I was thinking maybe something was wrong with my breaks. lol. That sound can be embarassing when around a group of people standing outside.
