That sounds like a lot of red tape. And it sounds like there is a possibility that MMC could prescribe some kind of repair that, for example, an experienced workshop could carry out in a completely different way? Or that a fault must first be approved as a fault? One can imagine many discussions... Is the clattering of the rear axle still acceptable, is the braking effect still sufficient, is the engine's ringing when accelerating still within the normal acceptable range, etc. etc. Not only the customers could be annoyed if everything gets the atmosphere of a petition. I am also thinking of the poor workshops that now have to formulate a description and submit an application for every warranty case.

And the point that Clemens mentioned... having to drive to the dealer twice for every repair... (if the car can still be driven at all) how long does it take for MMC to be so gracious as to send back a plan of action for the repair along with the authorization? So how much time between your two trips? Or, to put it another way, if the car is not roadworthy, how many more weeks do you have to wait before it can be repaired?

Does this procedure also apply to other brands? I have only experienced similar correspondence between the workshop and the manufacturer once, but well outside the warranty period. It was a very generously handled goodwill case without any costs for us, because the rear axle on our Mercedes E-Class estate car had rusted through after 12 years, and Mercedes replaced many axles for a lot of money so that there was no bad press.
