After 17,000 miles, tires developed excessive thumping. After a couple of conversations with the dealer, the dealer, as a favor, agreed to replace the tires, but I was responsible for the four wheel alignment. After 11,000 miles on the second set of tires, the thumping came back. Dealership agreed to check the alignment. According to them, it was within specs. They told me to talk to Michelin Tires. Michelin agreed to replace the tires as a favor. However, they are no longer responsible for wearing of the tires. So at this point, the car having 28,000 miles, the third set of tires has been put on. Mercedes will not accept this problem as their responsibility. HELP!
Mercedes needs to address this problem of why the tires are feathering. If I knew this before I purchased the car, I wouldn't have purchased it.
