Yup, noticed that on my 4 month old Jetta last night. I had noticed it a few weeks ago too, but was convinced I was imagining things!). At a set of lights, on a slight incline (enough to engage the hill hold), and was driving in manual mode. Not the most pleasant thing to experience in evening traffic. And yes, it decidedly did feel like the car was in "neutral" while still obviously engaged in "1" (on Manual Mode.
The only way out was to restart the car. I guess as with computers, a reboot always helps.
