When Mercedes screws up,They should make it right.No matter the miles our year.If there is a pattern of fault with some model they should fix it.Heads headgaskets Wireing harnesses etc.I worked a lot of years at a Honda dealership.Time after time I saw Honda step up and do the right thing.I saw a total complete engine replaced at 90 thousand miles.The owner had kept the car maintained.Honda said that one of their engines should not have failed that soon.I saw example after example like that.Honda made a heck of a lot less money on a car than mercedes.Mercerdes has grown fat and arrogant.What a shame.
