Thanks. I know things may change going forward but that can be said for any car I guess its just strange that the GLC seems to suffer so much more than the C when a number of significant contributory components are the same but I think before too long MB will have to do something to settle this one way or the other.
?? Why?
I want for nothing more than more of these cars not to do this. That would disprove Mercedes stance that it is a characteristic and thus that they not all exhibit it ergo something that can be fixed.
I would not wish on anyone what myself and many others are experiencing. It's truly horrible and totally detracts from what is otherwise a great car.
Why would I want to tear him or anyone else apart? I really don't understand that.
Totally tabloid style 
But what got to be done, has got to be done. I wouldn't be surprised when this gets picked up nationally and beyond Scotland soon

Yes me too, but I completely understand the frustration of GLC owners as the problems they are having are very significant but thankfully my C only occasionally clips a bit its odd really just feels like you have driven over a small pothole but haven't heard any cloncking noise at all. Maybe this will change but as I have already said I suspect this issue will fade away during the warmer months because if it doesn't then MB will have a lot of explaining to do!! But overall I am very pleased with the car especially when I select Sport+ and the performance exhaust engages and the car's whole characteristic changes into bruiser mode. But once again I don't fully understand why this issue varies so much across the range as you would think that all GLC's and C's would have exactly the same problem, or am I missing something?

Good pick up dejongj - That's 3 articles (including the honest john articles) that have come out since January. It's slowly building, but probably need a BBC or major news outlet to pick it up and run with it.
One or two of the major car publications will be next I suspect
BBC Have been totally unresponsive, not a word from them. Not even an acknowledgement regarding contact.
A very good question indeed
Especially considering Mercedes themselves say all are affected by this characteristic.Sport+ is pretty awesome isn't it
Make certain you run it in a little and let the tyres scrub (in a normal positive sense ) and brakes bed in.Take the main issue away it is a pretty awesome car.

If, as I suspect, the whole issue is due to the RHD transfer box, but the effect varies with respect to geometry and tyre combinations, then the wide variety in the manifestations of this issue is understandable.
The oil temp in the transfer box and its settings wrt torque share will all have an impact.
Despite the above, I suspect the fix might be a recall to fit lock stops.
As long as I can leave my house without having to resort to a two or three point turn
I mean my big old GL class can make the corners just fine, we down sized for a reason :bannana:

Not running it in??
Drove my C43 AMG around NW london over the weekend (haven't had much of a chance to drive since the car arrived) after sitting in the driveway for a couple of week. Went to fill up the tank, drove for 15 minutes to the shops and back..
Conditions were wet - but no rain as such. Any corner that was >= 90 degrees (i.e. turning at a T junction) resulted in crabbing / juddering. i get that the tyres were cold and the roads were slippery - however every single 90 degree + corner, not even at full lock? You seriously cannot class that as a 'characteristic' or trait.
I've got continental SP5 tyres - 18" standard wheels. it didn't ease up much even after the tyres warmed up. Does anyone with other summer tyres on have better results? I'm not sure how stiff the sidewalls are on the conti's - but is it worth investigating a more forgiving set of summer boots?

Well I have deliberately been using a mixture of driving modes to ensure all is well but am very careful when in Sport+ mode its more of an exercise to spread usage across the gearing range.
Interesting as I too have Conti's on 19's and haven't really had significant Crabbing/Juddering but it might be just luck on my part as my driving routines may vary to yours. Suggest you take it for a proper spin -good idea anyway with a new car- and see how you get on. Assume you did not experience this during a test drive? Have you spoken to your dealer and if so was their response the Standard MB reply to cold weather tyres?

I agree that it's a possibility. The interesting point would be that the modified vehicle then wouldn't meet the published specification at time of purchase, which would then open up another can of worms.
It may be an awful solution, but I disagree that it would be masking the problem. Instead it would be limiting the operating parameters in such a way that the problem cannot occur.
The more I learn about it, the more I'm inclined to the view that the 4WD implementation on this platform is a causal factor. Comparing the turning circle of the GLC with that of competitor products, at 12m it's not any tighter than the X3 or Q3. If it had been, then I would have been more suspicious of it being as a result of a desire to deliver an unusually tight turning circle.

There's really only one way ahead with this problem and that is MB have said that it is cold weather related and yes its certainly happening a lot during the cold weather at the moment. But soon the warmer weather will arrive and unless this problem either disappears or is reduced down to an acceptable level then MB have no where to hide and will have to admit its a problem that needs attention. There is sufficient video evidence showing the scale of the problem and it shouldn't be difficult to test these same vehicles during warmer weather. I reckon MB are holding fire in the hope this problem will go away but little do they know that warm weather isn't always good for your health. Does anyone actually know whether winter tyres reduces/fixes this problem or are we all assuming it will if we spent 3k on new tyres/wheels?

Just a play on words, you can no longer 'see' the problem. You can mask the problem in the same way as some suggest to not use full lock
