Consumer Description

When I got my Mercedes 2.5 years ago I would always notice a very strong gas smell that would come very randomly. I would have to open my windows for the smell of fuel to go away. I presented this to the Greenway Mercedes Dealership 2X VERBALLY and they told me that it is just a "Mercedes thing" and everything is ok because it is not "VISIBILLY" leaking fuel. Which it was not. However, the smell of the fuel is EXTREME, It would happen to me through out the year (in the summer and winter, regardless of temperature) randomlly. I would have to leave the garage ASAP when I turn on my car just in case the smell of fuel was extreme because my parents would tell me that it would even COME INTO THE HOUSE. I thought I was crazy to think this was normal and just a "Mercedes thing". But then I got a letter on August 2021 and did some research and saw I was not the only one and there is a class action lawsuit -Mercedes sent a letter on August 21 announcing they will extended the limited warranty of the "Fuel hose connected to high pressure fuel pump" from the original warranty of 4 years/50,000 miles to 10 years/120,000 miles. HOWEVER, This does NOT HELP, they are still saying it is a wear and tear and REFUSE to replace the defected MANUFACTORER part and INSIST it is not "seeping fuel" from the connection at the fuel pump, so it is NOT under warranty. I am confused as to why this is not a recall? Extending the warranty did nothing to help Mercedes Owners at all. They continued to claim it is "wear and tear so that is why the fuel is sweeping at a different location" AS WELL, two dealerships told me it would take them 24-48 hours for them to JUST INSPECT my car to see if it is covered. This extension did resolve anything, but made sure the dealerships deny even more. Now, I have to continue to leave my garage within 30 sec. so I don't suffocate the cats that sleep in the garage or have my family smell the fuel as I leave. And to open my windows so I can breath fresh air.
