Three problems related to other fuel system tank assembly have been reported for the 2006 Mercedes Benz C350. The most recently reported issues are listed below.
When the gas tank is filled past ¾ to full, there is an overpowering fuel smell in vehicle cabin. The offending smell also fills the garage and the garage door must be partially left open for safety: fear of explosion.
Every time I fill up the gas tank; there is a strong oder of fuel in the cabin. My wife and I have a newborn and now do not feel safe driving with such a strong odor. . This is a safety hazard.
Around December 2010 I began noticing there has been a gas smell from rear wheel housing and rear seat whenever I fill up the gas tank. I have experienced with various fuel level and concluded that gas smell starts when gas is more than 3/4 full. I have been trying not to fill gas more than 3/4 and have recently changed a delivery unit and all the seals, which have been problematic areas for many mercedes. The gas smell did not go away and I don't feel safe due to the risk of fire in addition to the unpleasant gas smell in the cabin.
