Clanking Sound When Leaving Park

Sometimes when my 18 DCT M2 has been sitting for awhile, usually over night.... I get in, disengage the parking brake, put it in drive and slowly feather the throttle to get it going, I hear a clanking noise and get a jolt. It comes directly underneath the shifter parking brake area.
I always confirm that I took off the parking brake but it sounds like something is not engaging or disengaging properly.
Doesn't happen often, maybe 3 or 4 times now in the 6 months of ownership.

Anyone else ever get this?

Does your car sit outside? If so, do you notice it in correlation with it being wet outside, after a rain or a wash?

My guess is that the rotors are rusting slightly (as they should), and the jolt is the pads "unsticking" themselves from the rotors.

Ah! I don't park outside but I did wash last night and it happened this morning.
Thank You! Think this could be it.

Yup. Sounds like rotors. It happens, nothing to worry about.
