This happened twice and I havent been able to replicate. After being parked in the garage for 3 days, I start the engine, wait for the engine to warm up and RPMs to settle. I shift the pdk from Park position to Drive. The moment the car rolls forward, I hear a clank noise and the car also feels like it was stuck for a split second. This feeling does not come from the back end but from either the front axle or front wheels/brakes.

To better describe, it felt like the wheels were glued or frozen and because the car moved forward, the glue broke followed by a quick metallic clank noise as the car made its initial roll.

Really curious what it could've been. im ruling out dragging brakes because the noise happened only in a split second as the car started to roll. Could it be the 4wd system?

 

Sounds like the brakes were stuck on the rotors. Happens from condensation building up on them and them sitting for a bit. Nothing major

 

After I wash my wheels. My brakes bond to the rotors so bad that I don't need my e-brake on. Makes a huge pop sound when it releases.

 

Yes! forgot to add that its a humid summer right now and lots of condensation. Thanks for the tip, learn something new everyday!
