Love / Hate thing I have with my MY at the moment. Love it when it actually works but I guess I was one of the few unlucky ones to get a brand new dud. Picked my one up back on 8 Mar, 800 miles in and I get the dreaded assist errors whilst driving (ABS, Traction Control, Hold Assist, Powersteering, Regenerative Breaking disabled whilst driving!) and happens on almost every drive very frequently. I suspect a water ingress on one of the wire harnesses.
I live local to Dartford so that would have been my first choice SC but they were "closed" back in March and made me go all the way to Park Royal SC who were terrible. Didn't fix the problem and left black hand prints all over my pristine white interior. They did adjust the large panel gap on the boot door though.
3 months on, today was the first appointment I could get at Dartford SC with a loan car (yes it is a very long wait for SC allocation to fix any delivery day problems) so hopefully they finally fix the dangerous issue of having all the driving assists turned off unexpectedly whilst driving and also repaint some peeling paint of the front bumper (which was also there on delivery day - so build quality still a problem then).
On the plus side, I did get a 2017 MX for a loan car
