Has anyone experienced when you come to a stop in the car at a set of lights for example and just hold your foot on the brake in drive or in stop/start traffic and then pull away, the car does a jerky take off (with a bit of a clunk)? The workaround is put it in neutral and then just engage drive before actually taking off for now, but a bit of a pain.

Have you tried searching forum as this is a common complaint.

an example

FL2 Metropolis SD4 Auto 2014 2017- (16k - 77k+ miles) (MY2015)
Metro in its 11th Year of (Extended) LR Warranty / Full LR Service History
(Expensive, but Trouble/Worry free - hopefully?)

thanks Ian, I had no idea it was such a common problem, I will take a look.
