One problem related to other fuel system tank filling/charging has been reported for the 2008 Mercedes Benz CLS63. The most recently reported issues are listed below.
My car has a fuel tank leak and defective fuel sending units. A few days ago I noticed a very strong fuel smell after filling up my car at the gas station. I took my car to the dealership and they said that the fuel tank is leaking and both fuel sending units need to be replaced. I feel that this is a serious safety issue and that mbusa needs to correct the underlying problem and issue a formal safety recall.
