I'd owned several (8) Merc's from the 90's - 00's none have ever done this. This, as in the vid posted of the GLC or can I relate to the comments on the C43 thread. In actual fact I've never had any car do it let alone Merc's and that includes others that I drove from Audi Quattros, Subaru's to Land Cruisers. Nor have I ever read about the motoring press commenting on it previously and it must be a noticeable issue for the likes P.H./Autocar to write about it twice, once being a dedicated article on the problem.
Sure, maybe any car can have a slight degree of this issue including two wheel drive cars but I doubt very much the problem is to the degree of GLC's and C43's.

I've been willing to dedicate most of my disposable income on cars over the last 40 years, and between me and my various SWMBO's have taken delivery of over 50 brand new cars over those years, and nearly as many used ones.
Many of which have been 4WD, inc LR, RR, Jeep, Dodge, Audi, Merc, Suzuki, Honda, Toyota, and others.
I have noticed the slight/mild phenomena before, but never ever to the extent displayed by C43's, GLC's.
Unlike many who seem to want to dismiss this issue as normal, I've driven both the C43 and GLC's and experienced it myself. It is a fault. It's far far worse that the mild issues that some try and compare it with.
MB themselves confirm it is a fault. They just argue that its only effect is on comfort.
I have no ax to grind on this, I'm not an owner of one, thus not 'emotionally involved', and can be objective (ok so it's still my opinion).
It's interesting that in a recent test of a BMW 320D X-Drive by Evo, they complained that it 'had the turning circle of a supertanker'. Maybe this is how BMW have avoided the problem. In my first post on this subject having borrowed a C43, I commented on how tight the turning circle was, so with the (compromised RHD) technology they are using, maybe you can't have a tight lock without the judder?
