I was slowing down to exit the highway and when I stepped on the brakes, I felt no pressure on the pedal brakes. I pressed harder on the brakes and still the car didn't slow until I got to a slight incline at the end of the ramp. Then a red warning light on the dashboard appeared reading "reduced brake power". I turned off the engine and waited a couple of minutes. I managed to get home safely. I called a certified mechanic and he told me to call the Mercedes benz dealer because of a possible recall. As per the mechanic, this are the faulting codes: c2131 - pressure reservoir faulty c249f - operating time of component a7/3 (sbc left hydraulic unit) is exceeded c25d5 - hydraulic fault malfunction in pressure supply as of this writing, my brakes have not been repaired. *tr

1. Fueling the vehicle- after fueling the vehicle and filling up the tank, a very very strong odor of gasoline/fumes stays in the cabin of the vehicle days or until gas tank drops down to under half a tank. 2. Fumes are so strong, causes occupants headaches and nausea 3. Vehicle stopped on idle- when coming to a complete stop, vehicle begins to choke, as if its about to turn off. Need to put the car on neutral and press the accelerator to stop the car from choking. 4. Turning- when making turns- the vehicle will randomly choke as if not receiving any gas, and as if its about to turn off. The power steering also goes inactive, leaving it almost impossible to make the turn. This is very dangerous especially on left hand turns at intersections. I have stopped turning in front of o

Complaint # pe12001 I noticed occasional fuel smell originally 2-3 months ago. Initially smells were mild, now smells are noxious and getting worse. At my last 10k miles oil change, discussed the problem and progression getting worse with my Mercedes certified mechanic. The rear seat was removed, to find the upper part of fuel cell under passenger seat, with deterioration of upper part of fuel cell plastic. There was actually a gas "puddle" visible that had seeped through the top of fuel cell/sending unit. Very dangerous situation, risk of fire, and also causing headaches from noxious smell of gas !!! What can be more dangerous, gas leaking, and seeping into the interior cabin of an automobile ??? Please intervene with this dangerous problem with a recall before
