Yes,
2017 A4 Avant. First time it gently rolled into another car, which prevented it from going through a car showroom window! Happened again today. Luckily no damage.
the fist time I put down to human error, but the developed a bit of OCD about constantly checking the handbrake, so it was definitely on.
alam has been going off for no reason for the last couple of weeks, so not sure if connected.
