Yeah, I think it's embarrassing for Mercedes and I will not try and defend them.
There is no excuse for not getting quality right in the first 90 days of ownership.
I know that the argument in defense of Mercedes is that these cars have many electronic goodies, and that expectations are inappropriately high.
Well, that argument doesn't work for me as Lexus and Cadillac rank very high in this survey, and they have as many or more crazy electronic content as Mercedes.
The last time I was at the dealer, there were two different customers of new-ish s-classes that were in for the same problem the third or fourth time, and both owners were furious. One of them said they'd never own a Mercedes again, and the other would still consider it, but didn't think he could afford it after the warranty expired.
