My 2022 model C class developed a fault, my Mercedes dealership quickly found the cause of the fault and ordered a new part from Mercedes parts division . I have now been informed that the part is not in stock and on back order . I was also informed it could be many weeks or even months before the part is available !!!. My car has been at the dealership for over 8 weeks ! To be fair the dealership have been very helpful and I have a courtesy car. However Mercedes customer service have not responded to my telephone calls seeking help to expedite the part or my e mail complaint about the parts delay lack of information . This is my first Mercedes and probably my last after this disappointing service . Be warned before you purchase a new Mercedes!!!!! Date of experience: October /Nov 2023 and it could be next year before the part is available ....... 1 review GB
