Morning All last week my 2014 C63 (W204) went into mercedes for the big A service. its just hit 22k. the advisory on the service sheet was that both my front wheels were buckled - this is confirmed by the small vibration i get through the steering wheel at motorway speeds. The car was bought from a Mercedes dealer, i have got it on a service plan for two years and it still had a years left of used approved warranty. While the warranty doesn't cover wheels, tyres and bodywork etc, i was looking for some sort of good will gesture because of the above. i was not expecting a freebie. i was met with a very abrupt service manager who was incredibly resilient in helping me what so ever. after making my point a bit clearer, i was offered 10% off a £475 wheel, which id need times two. Good, but i dont think thats good enough really. ..anyone have any experiences with this? i know the optional 19'' wheels are prone to cracking, but buckling? i find it an odd coincidence that both front wheels have cracked when the car only has 22k and is used for motorway commutes..although i appreciate it can happen anytime. I took the matter to Mercedes online and explained the above, they returned to me this morning extending apologies on the abruptness of the manager and reluctance to help me at all, and also apologized for the fact i had to return to the dealer as they failed to turn my service light off before handing the car back. The chap on the phone did state that its down to the dealer to offer any discounts or 'deals' and that the dealer claimed margins were too tight on the wheels to give any discounts. mad thing is i had a wheel changed under warranty over Christmas as it started to corrode! although tyhis is classed as a manufacturers fault. Several searches online make it clear these wheels crack and buckle quite commonly which says there must be a design issue with these? or that the tyre and wheel combo just is not for uk roads? Looks like il be getting stung for replacement wheels. whats your experience with this or similar?
