Unfortunately for me I have one of the AMG versions. My dealer is being absolutely useless and refusing to do anything. The after-sales manager says he's driven 30 GLC63s and mine is no different to the others. That just tells me they're all broken!Just to add to this, at the end when I was speaking to the service guy, I was obviously very thankful but also annoyed that a fault was being overlooked.
He actually said 'thank god you don't have the AMG version, they can't be fixed due to different xxxxx' sorry can't remember what was different, possibly steering rack.
I think there are two ombudsman organisations being mentioned here. If the car is leased/PCP then the Financial Ombudsman will probably fall in favour of the customer. However, the motoring industry ombudsman are weak and will bow to the manufacturer.After having my case, for exactly the same issue, decided in favour of Mercedes UK I just don't understand how the Ombudsman works. Surely we should all be treated the same? The Ombudsman ruled in favour of Mercedes because Mercedes admitted this was a 'characteristic' (I hate that word now) of the car. When I sent them the PDF of the decision that was ruled in the customers favour, for exactly the same issue, they said that there were different rules for cars purchased via 'hire purchase' as to those that were via 'lease'. I've no idea if this is correct as I know nothing about this sort of thing...so I've just had to accept it. As this characteristic must have been there at the point of sale the Ombudsman said to open a new case with them against the dealership that sold me the car. Their point being it would not have been of acceptable quality or 'fit for purpose' at the point of sale thus violating the 'sales code'.
Overall gutted that the experience of owning such a car has been blighted by this problem. The intention was to purchase the car outright next June at 36 months of ownership but there is no way we will do that now - we will have to return it losing over £30k in 3 years.
I can't see us getting anywhere with the second Ombudsman case but will update the forum accordingly when I know more.
Merc now have a mod to fix this, I got mine done by them under warrant. It’s been fine since without changing any tyres. Get in to see the dealer and make them do it, it’s no skin of their nose as Merc paid!Mercedes GLC Clonking and juddering on near full steering lock
I have had this problem since new but now the weather is cold and damp or wet the problem is much worse. I have viewed other owners concerns about this phenomena and would like to document my experience.
The car has been with the Mercedes dealership and they have coated the drive shafts with a lubricant to hopefully reduce or remove the problem.
The service manager told me that the clonking noise is from the tyres and another manager told me the car is trying to drive straight ahead (whilst in a turn) and it is the scrubbing of the tyre on the road which is causing the noise and the judder.
The service manager told me the car is safe to drive. However, I'm not so sure.
If I need to turn sharply to avoid a collision I do want the car to turn and avoid the object rather than juddering towards the object.
My wife has said that she would not drive the car until the clonking and juddering was eliminated as it does feel and sound bad when it occurs.
Over the next few days I will check if the lubrication coating has any effect on solving the problem.
I would like to hear the latest situation with regard to all those owners who have the same problem. I.e. is there really a fix or is it a inherent design fault.
