Thanks Tony. I would also be sceptical about this and either way does not place me in a good position (yet). If MB (in the unlikely event) agree with these next steps, they may say that this is my choice and my choice of tyres - even if they (again, in the unlikely event) agree to paying the ~£1k for a set. If that does not resolve the issue, I may be even more stuck, as the car would no longer be in the supplied condition. Perhaps my best bet is to stick to the current plan, which is to make it clear to them that they need to address this long standing issue on my car (🤞) and also address the other concern as to why (despite knowing of this and being instructed by MBUK to inform all customers before they sign a deal of this issue - either to provide option or to walk away) they failed to inform me throughout the entire process. My car has only does 350miles...
PS - perhaps the tyre change is to be considered way down the road, if MB ultimately do nothing and remain uninterested. Especially as I really like the GLC 43 in every other respect...

Thank god I came across this thread! I bought my first GLC last week and having left the dealership after about ten miles I started having the same issue. It was too late to return to the dealership and I was too busy on the following days. When I had some spare time I registered on this forum I started looking for answers here. I also came across a viral video of a russian blogger who had trouble with the mercedes dealership and the frustration made him burn down the car and record it - it was a brand new gle I believe. I spooked me more as I didn't want my car to end up in one of scrapi.com yards.

What age of vehicle are we talking about?

Hi Andy,
From my research, I believe this to go back to at least early 2017, perhaps even 2016 and (again from my research) believed to be affecting RHD AMG vehicles. The bigger your wheels, along with summer tyres, run flats and <10C seems to significant factors in this. I can therefore add, that if you are able to avoid some of these factors in this equation, then you are less likely to see the issue. Ultimately, MB need to fully address the issue, rather than subjecting owners to manage this issue on their behalf, which for some is at least a costly affair with the speedier and odd tyre wear.

Was the issue addressed on the 2020 facelift model do you know?
Sadly not...issue definitely remains on the 2020 facelift (which I believe was released in 2019). I still believe this is a fab car...but in order to mitigate the issue, the smaller the wheel the better and avoid run flats...

Hi Everyone, I have exactly the same problem as described above.

I took delivery of a GLC 43 AMG in November and the car has been back to the dealer twice, and I have complained to Mercedes.

Mercedes have now come back and said that the only solution is winter wheels, as this isn't a performance or safety issue.

Problem is that I have the optional 21" wheels on the car and there are no winter tyre options available. So it's a complete set of wheels that are needed at a cost of £3000.

That isn't right in my opinion, how can mercedes be allowed to do this to customers?

I would also appreciate any updates from any other owners on their problems with this issue with full lock.
I have the exact same problem I was just looking for winter tires today and there are no tires with the same specs as my GLC 43 AMG 21" but I'm not sure if that would not solve the problem anyway because what if it continues to happen in the later months I've only had the car for a few weeks but that does really bother me but also concerns me.. I'm thinking of going to the dealership and sitting down with them to try and find an alternative solution to this even if it means them having to change the car for a different model...Please let me know if there is anything else I can do.

It is fixed in the MY20 models for MB but not AMG models. Fixed to the same degree as the older models with the new knuckles anyway, which means 95% fixed and certainly not concerning in my experience with 20" wheels and run flats.

Hi David and welcome to the forum. I'm pretty sure this issue only affects RHD conversions. I suspect it has something to do with locating the steering box on the other side of the front differential. Due to space constraints in this area it is quite possible the Ackerman geometry used to set the correct steering angles is not quite the same as on LHD models and this is what is contributing to the crabbing issue. There is a thread running on MB World also discussing the crabbing problem. As it is more of a USA/Canada biased forum, I would suggest you also check there for reports pertaining to LHD cars:

The MB World tyre scrubbing thread
Negative ... it is NOT just a RHD problem. The exact same thing happens on my left hand drive GLC 43 and I live in Sacramento, CA. I have walked along the car with my wife turning the wheel at slow speeds. It is not a tyire (tire?) issue, it's in the turning suspension (Ackerman geometry?). It's a heavy mechanical clunk and not the tyre scuddering.
I havent done anything about it yet, but I intend to. The car drives fine and is not a safety issue, Mercedes is correct on that one. But it is definitely an engineering problem.

Hi,

if I was to buy a second hand GLC with the knuckles fixed, does this mean I’m all good. The one I’m looking at is on 20 inch wheels. Or is the advice to avoid because it’s about £25k and so not a small amount of cash and too much hassle downstream?

If it’s had the New Knuckles fitted you should be ok 👍

Ours had the knuckles replaced under warranty 2 years ago and it’s fine + this fixes the rapid tyre wear.

Good car

Tony
