What 2004 Mercedes-Benz E350 owners say
Fuel & propulsion system
2004 Mercedes e320 has a strong gas smell. Took vehicle to dealer and found out that "1/3 the fuel tank has a cover on top of it-sandwiched between the top of the tank and the floor of the vehicle the tank is leaking where the cover meets the 2/3 tank when you pull the back seat out you can see the tank top-fuel is seeping out staining the side of the tank" I was told there was a 15 year extended warranty due to this issue and I was advised it expired. I was never notified of the extended warranty and I have owned the car for 12 years. I reached out the Mercedes headquarters and they advise its nothing they could do. This is a big safety issue because the car can catch on fire. Shouldn't this have been a recall? Does someone have to die before it is. Mercedes still stated nothing they could do. The tank will cost $2300 and they advise no aftermarket available. …
I inherited this vehicle from my father and when I fuel up the smell of gas is overpowering. I changed hoses and gaskets in 2018 and was OK until 3 months ago. Now it always smells like gas to the point of light-headed and vomiting. Called Mercedes there was an active recall that expired in 2019 but I had never received notices and spoke to my mother that also never received. Mercedes admitted they had incorrect address so they were sending to a deceased person to wrong address. But since it is expired, there is nothing I can do for a faulty fuel tank that is extremely dangerous
