I just experienced my first presenting door handle issue with my 7/2018 build. This morning after summoning it out of the garage (like every morning) I noticed the drivers door was opened but the handles were half way presented. Odd I thought so I closed the door. The handle retracted but it made a series of 3 humming noises. I unlocked the door and the handle tried to present but wouldn't. Instead it made those same 3 humming noises then the door popped open, handle stayed in. Its now at the point where its just making a constant humming noise (while parked or driving) and the handle will not present at all. I now have to crawl in via the passenger side to open the door.
Here is a sound clip of the hum from inside and outside of the car.
