I was looking at the spec for the Urban edtion a few weeks ago and I'm sure it said it came with All Season tyres. Might have been a lease offer I was looking at, so I suppose the spec could have been wrong.
ETA: Just looked at the brochure and it seems it comes with summer tyres - doesn't even offer All Seasons as an option, which it does at no cost on some other trims.

Good Lord , you couldn't make this $hit up. As I have said before on here I can't believe this car is still on sale in the UK.

I can’t believe people are still buying it.

Just spoke to my MB dealer regarding the emissions recall.
Whilst on the phone I mentioned the “steering knuckle fix” and they looked into it for me. They were unable to find any updates or news bulletins regarding this but have noted our conversation.
If anyone receives further information about this, could they please post reference numbers etc on this thread?

Hi Tomtowner,
We purchased a glc 220d sport, and have experienced the same crabbing and juddering noise when the steering is turned especially in cold weather. When it was 1st serviced in 2017, I was informed that it was quite normal, but having read many other views from others on this forum I wrote to Mercedes head office, and this was part of the reply from them:
"I can confirm that the characteristic you are experiencing comes from flexibility within the tyre sidewall, the grip between the front tyres and the type of road surface being driven over. It is something which can be felt only at very low speeds, and when a certain percentage of wheel lock is engaged for turning. This is demonstratively more evident in colder temperatures due to the changes in the tyre rubber elasticity. As such, since this is a characteristic of the car and not a fault, it is not covered by your car's Manufacturer's Warranty. Please be assured that this is a comfort issue and does not affect the safety or overall performance of your car."
We have another glc 220d AMG, which also has the same problem. Could anyone help please. Thank you.

Hi,
I am just starting my own debate with MB on my 21' wheels on a GLC C63s. For some reasons this morning MB have said it will replace tyres and fit a knuckle on the steering system on all other models other than an AMG. Does anyone know any reason why MB are treating the AMG 63's differently to other GLC models? I understand on the knuckle solution, but their stance on tyres seems odd to me. As I understand it the difference is only really engine based and the car has a "winter mode" to limit speeds to meet the speed rating of any winter tyres.
Thanks

I am also interested in this "steering knuckle" fix having taken an interest in this topic some time ago. My guess is that changing the angle of the steering knuckle may alter the castor angle which may help with the crabbing issue at full lock. It may not be a complete cure but like the all weather tyres help alleviate the worst of the symptoms. I believe that the 43 and 63 AMG 4WD models may already have these revised knuckles fitted as standard and the fitting of all weather tyres may be deemed inappropriate on these wide tyred performance models???
Anyone got precise details on what the steering knuckle modification does ?

I've had the steering knuckle fix done on my GLC 220d Sport. I did a write-up with some photos of the installed modified knuckles over on the GLC Forums. Here's a link to my post:

Excellent descriptive post complete with clear pictures which leave readers in no doubt as to what a front suspension steering knuckle is. Nice one!
Great News.......
Well it looks like the flood gates have been opened in Oz for the knuckle replacement program to RHD vehicles.
Our 250d, with air suspension finally was approved last week and car was converted.
Limited driving to date, but it seems what we thought it should be like on wet and cold roads doing is actually finally happening.
Our tyres are Goodyear All Season, run flats.
Can posters who have the conversion done please let us know if their tyres are All Season type, or original Summer runflats, by brand.
If a Coupe, were tyres changed or are they original non run flats ? Brand ?
Thanks to everyone for sharing info.

My brother in law just got most of his money back via the financial Ombudsman and MB have made the payment.
The following is the decision:

Great to hear your brother in law got most of his money back. How long did he have the car for before he made the complaint to the FCA?
has this issue been resolved in facelift 2020 GLCs?

This is my first post on the forum
Thank you to everyone who has contributed so far on the issue, it has led to my car having the steering knuckles replaced under warranty (yesterday), so no more pesky tyre skipping.
Having said the above, after the fix I have noticed a really unnerving problem where the whole car is slipping significantly to the left or right when driving over rough roads or large expansion joints (on bridges for example). I really feel that this is worse than the crabbing issue, because it happens at higher speeds as well. I know that today the roads were a little damp when I felt it, but I've never driven any other car that does this in the same conditions.
Of course I'll be picking up the phone to the Mercedes Dealer who did the work, but I wanted to know if any of the good people on this forum may have an idea on why this might be happening before I do so?
