Authorized Mercedes Benz dealership in Ann Arbor, MI advised replacing tires, valve stems and other items. I dropped off the car at the dealership for the work. During Alignment they found right rear out of spec due to subframe rusted out. They said rear subframe replacement is needed. This is a very dangerous condition and Mercedes Benz does not cover rusted subframe replacement costs at all, neither do they advise routine checks for this problem which seems to be a very common issue for the C Class. In Europe and Canada, Mercedes replaces rusted subframes for free. Why is it not done for free in USA? This is a very serious issue and can cause serious and fatal accidents. The cost to replace rusted subframe is very high and car can break down while driving without any notice or warning. Additionally, there is no warning light or signal displayed to alert the driver of a potential problem. The car can have an accident without any warning light or alert.
