Five problems related to other fuel system tank assembly have been reported for the 2010 Mercedes Benz GLK350. The most recently reported issues are listed below.
Extremely strong smell of gasoline when tank is filled, Mercedes Benz recalled 2011 and 2012 model year Glk350 vehicles for a fuel leak but did not recall model year 2010 Glk350 vehicles. The same recall is necessary for model year 2010 glk 350 vehicles.
There is a very strong fuel odor coming from rear left passenger tire area when tank gets completely with gas. I noticed the smell after leaving the gas station and bringing the car home to park it in my garage. The gas smell is so strong, it leaks into the house (via attached garage). Initially I assumed that I must have just spilled a little gas while pumping it. However, the second time I went to fill the car up the same exact thing happened. To date we have no remedy for this problem. Again, this has happened twice so far.
Plastic seal on gaskets for gas tank failed on both sides of car. Causes leaking of fuel and odor into passenger area of vehicle and danger of explosion due to leaking fuel. It occurs when gas tank is more than 3/4 full to full of fuel.
Excessive fuel smell, turns out it's the fuel tank, was informed plastic fuel tank seam is splitting and is now a fire/safety issue. Informed that mercedes is aware of the problem and replaced many during warranty period, but now since my warranty is over this safety repair will cost me in excess of 3,000. 00. This is a fire hazard and big time safety issue that the NHTSA needs to look into.
On 4/24/16, a Toyota rear ended me and pushed me into the vehicle in front of me. The damage would have been repairable until my car caught on fire. It looked like it started in the inside above the gas tank area, but the man working at the impound lot the next day said it looked electrical. Either way, the impact should not cause a mercedes to catch on fire. I was on a city street stopped at a stoplight.
