Fuel system
Reports naming fuel storage or delivery — tanks, pumps, lines, injectors and fuel leaks.
From owner reports, verbatim
The contact owns a 2010 Mercedes-Benz S550. The contact stated that after refueling, there was abnormal fuel odor present inside and outside the vehicle. The cause of the failure was not yet determined. The local dealer and manufacturer were notified of the failure, but no assistance was offered. The failure mileage was 110,000. The contact stated that the gas leak was caused by a cracked fuel filter housing. The fuel filter and the fuel pump was replaced. The contact is requesting a full reimbursement of the cost of repairs.
Vehicle garaged in storage for summer. Upon returning strong odor of gasoline was detected. Reluctantly drove to dealership and prognoses was determined that (fuel pump strainer) had malfunction thus soaking the entire rear passenger compartment and seat cushion. Upon investigation Mercedes has had a problem in other C -models and has extended warranties for 15 additional years for this same problem. This vehicle is a S- 550 model. Dealership has denied any responsibility. I think the vehicle is unsafe at ANY SPEED. Never should fuel enter the passenger compartment of any vehicle. Video on file at dealership.
