What owners say
Fuel smell suspension drivers seat tearing brakes
In september, 2015 took my vehicle to houston greenway (3900 southwest freeway; houston, texas 77027) for an inspection of the fuel tank (strong fuel odors were detected). The inspection revealed that the fuel tank required replacement. The replacement work was done and I paid for it out of pocket. I recently received a letter from mbusa stating that the mbusa had elected to extend the warranty on my vehicle
I began smelling fuel in the cabin of my car and contacted the mercedes benz dealership in my area, westminster, co. The woman I spoke with told me that she was unaware of any issues, but that she would look into it and get back to me. I never heard back. The smell was getting worse and after 3 weeks, I could not drive with my windows closed, gagged when I got into the car and smelled like fuel upon exiting the car. I called mercedes benz again and asked if I could bring the car in. I was told I could and that there was a warranty extension for faulty fuel tanks. The fuel tank was allegedly repaired, but upon returning the car to me, the car still smelled like fuel. I thought the smell might dissipate over a few days, but it did not, seemed to get worse again, so I took the car back in. I was told by the service rep that the fuel had leaked into the underlayment of the car and was deteriorating the floor boards. I was also told to "not smoke in the car" by the service rep. Mercedes benz is now refusing to repair this damage caused by the faulty part. They feel that the car is "safe" even though I was told not to smoke in it. I don't smoke, but if there is an electrical spark or I get in an accident, I don't want the car to blow up.
Strong smell of gasoline in interior of car along with smell in garage after overnight parking. Checked engine for leaks as well as general tank area. Negative. I think that the fuel sending unit (under rear seat may be loose or defective. Can't over emphasize the strong gas smell, while stationary--seems to dissipate on movement.
