Tire failure resulted in being towed to Sudbury dealership, I was advised it was a blow out and a covered by warranty. Overnight in Sudbury, then presented with full bill. I deal with Mercedes Barrie and asked them to straighten out the claim of tire blow as listed on the paid invoice and credit me. Buck was passed all round Barrie and they said it was a Sudbury problem. "It is a Mercedes problem" and I "DON"T LIVE IN SUDBURY". Passed on to Mercedes Canada who said I needed to deal with Sudbury. My fishing friend had the same problem from the same fishing lodge 3 years ago and was towed to the GM dealership in Sudbury. GM paid the overnight hotel, transportation in Sudbury and full warranty on the tire. I will not be dealing with Mercedes Barrie for my ML 350 and C300 again. As for Mercedes I will not be renewing my lease on the C 300 next year. I had 4 Mercedes before this but not again.
