Mercedes GLC Clonking and juddering on near full steering lock

[Toobad]

Also notice someone has replied and mentioned something happening on February 27. What's all this about then?

Mercedes have promise to issue another public announcement to further clarify this crabbing issue by or on Friday 17th February. Things may or may not become a whole lot clearer by the end of this week.

Nothing but praise for the team at Wheels In Motion - it was enlightening and I feel a little step nearer but lets take one step at a time.

For details of the geometry check on my GLC43 please see here.

In the meantime the latest campaign, live since this morning is; Dear Garry Savage, there is something you need to know.

Directly aimed at the CEO of Mercedes UK. Posts are starting to flood in from owners, and the page is beginning to build nicely. Only registered and verified users will have access to a form that will make a post automatically on that page.

New video taken yesterday morning in our GLC 250d, very slowly and cautiously reversing and driving onto the main road, dry road surface and temp was around 4 or 5 degrees.

If you own a GLC and are experiencing this problem, I would strongly recommend registering on the Mercedes Benz Crabbing web site > https://www.mercedescrabbing.org/

NN 8255 Tyre Skipping

I have been given a document from my dealer which mentions the requirement of new prospective owners to sign the acceptance of the issue.

I wait eagerly for the update due today (17th. Feb 2017) which should relate to existing owners.

I have made a application to the DVSA (Vehicle Safety Branch) of VOSA regarding the safety of the vehicle. They have informed me that they are aware of the issue and are in contact with the manufacturer, Mercedes.

I hope we can have some news which will satisfy each and every existing customer.

Not sure I like this as who would sign a waiver at their local swimming pool that if they get wet then the pool isn't to blame. Stupid analogy I know but its all I could think of when typing this.

 

[trapperjohn]

So new owners sign to say - Yes, I know this will happen and I'm happy for my car to behave like this. Eek.

Existing owners will be told "tough" by the sound of it, probably many more words than "tough" but amounting to the same thing.

"I acknowledge that this is a characteristic of the car and is not an issue which will compromise safety.

I can't see how any buyer can sign that, simply because he/she can't acknowledge either of those two things. The sentence is stating that the buying is agreeing that it's a characteristic of the car and it's not something that will compromise safety. Unless the buyer is an expert across all mercedes cars and has a detailed understanding of the mechanics of what is causing the jumping and the implications of all the possible effects it can have on the rest of the car, the buyer is not in a position to acknowledge that it's not an issue which will compromise safety.

At the very most all a buyer can acknowledge is that he/she has BEEN TOLD BY THE DEALER that it's both a characteristic of the car and an issue which will not compromise safety.

Not thinking of this issue in particular, it's like a buyer being asked "I acknowledge this car is safe". No buyer can do that.

It also relies on the sales person demoing/explaining correctly, which ain't gonna happen.

That's dreadful

 

[SquabzZz]

Does this happen only with the bigger alloys that have small tyre wall ? Or all tyre sizes ?
Only askin as the MRS wants a GLC but this could be a deal breaker

With Mercedes saying this is not a safety issue, raises two important points.

1) Mercedes can't be testing this correctly as if they haven't acknowledge the problem correctly, they don't have the correct knowledge of the problem.

2) By not recognising the problem, they are dismissing what customers are reporting, therefore they can't be recording the effects on customers correctly, which again shows lack of knowledge.

You can't test for something that you don't recognise or have knowledge of, it doesn't take rocket science its bloody human nature!

Therefore, saying its not a safety issue by using inadequate testing, is rather negligent.

All this is typical software developer behaviour, which effects the software industry and which is why technology in general always breaks and is full of bugs/flaws, its human nature to think what is produced works and has no hidden problems.

Clonking

I am wondering what the legal situation is regarding the requirement for the sales person to ask the prospecting owner to accept the issue and relating this situation for existing owners.

Surely, the same condition should apply, otherwise it is discriminatory.

I would think that Mercedes are legally bound to also place the same requirement for current owners. In other words, we need to sign that we accept the issue. If we don't want to accept the issue we should then be able to return the car for our money back.

Is there anyone thinking of taking legal action?

Another point is the value of the car is reduced because of the issue.

I believe that Mercedes must known about the issue before production started. Cars are tested before going into production and therefore such a loud Clonking and Juddering must have been discovered.

Has anyone news of the update which should have been out on the 17th. Feb 2017.

Its strange...I've driven a new glc 350d 4matic 20" alloys and had a play with it in the car park in the knowledge the judder is there, I tried to make it do it...it did eventually in reverse mostly , but honestly seemed so trivial I wondered what all the fuss is about, made me think people are being OTT....I have however seen vids where it seemed very bad so I dunno

Just got a C43 it does it I knew it does before I brought...seems all the 4matics do, once it warms up its fine....I guess however you tolerate it more on a amg performance car....sort of performance car quirks....for the record the c43 is worse

That's very interesting, and may actually demonstrate that the fault is restricted to 4 cyl GLC diesels. (Plus of course the 6 cyl petrol).

I guess the 350 is a similar set up to the well proven ML/GLE in RHD flavour. If not then maybe it's just benefited from a year or more R&D.

350d probably has more weight over the front wheels........

It must be a characteristic of the car or the models that do it as it is the steering geometry.

Remember the old Triumph Herald with a steering lock giving 26 feet turning circle....if standing by one of these whilst seeing it turn you would crap yourself as the sideways scrub and juddering was out of this world.

Of course all problems will can be eliminated but with this problem just reduced the steering lock!

I remain unconvinced that it is the "steering geometry" that is solely responsible for this? I say again..... I suspect Transmission Wind Up is the root cause and tyres, either mitigate or amplify the effect of the wind up.
