There was a smell of gasoline in and outside the car when the car was idling. Also, a smell of gasoline in the garage around the parked car. Also a smell of gasoline after starting the car, that went away after driving. I called the service department. They gave me an appointment one week later. I have no complaints about the service dept. When the car was repaired several hours later, the report stated "found seep at fuel hose to pump", and then, "replaced upper fuel hose to high pressure fuel pump". They told me it was no charge because they knew about this problem happening in their vehicles and had extended the warranty for it. I was/am very concerned because(1.) if I had been in an accident, could have more easily been a fire? (2.) Mercedes knew about this and to my knowledge have not let customers know, (3) I kept up with all maintenance/service visits and I was never told to be aware of this possibility, (4) when reported by me, there was no procedure in place to prioritize scheduling this repair. I may be wrong in my analysis and do not want to cause anyone any trouble. I just think if one car fire can be avoided that is important. If my thinking is incorrect, I apologize sincerely for my reaction to this situation.
