The problem
On certain sport utility vehicles, the fuel return hose between fuel tank and return line can be permeated with fuel. This situation results from the expansion and contraction of the hose under pressure causing microcracks in the hose material.
The risk
These microcracks May cause fuel leakage. Fuel leakage in the presence of an ignition source could result in a fire.
The fix
Dealers will inspect and replace all fuel return hoses with the appropriate hoses free of charge. The recall began on September 27, 2005. Owners May contact Mercedes Benz at 1-800-367-6372.
