What owners wrote

Took our 2012 mercedes-benz ml350 bluetec to the dealership numerous times due to an overpowering fuel smell and burned plastic in the cabin of the vehicle. We had to stop several times because we felt sick as if we were going to pass out and/or throw up. But, then it started to affect our children and we demanded that the dealership find the root cause. They finally determined that it was a fuel leak around the fuel injectors that completely charred components in the fuel injection cavity.
