While my wife was driving our 2009 mercedes benz ml63, at approx 65 mph, on the 101 loop in scottsdale az, she experienced complete engine failure. The engine completely shut down on her. She luckily was able to coast over two lanes to her right to an exit ramp.
I moved into the turn lane and the car would not start. I call the tow company and had my vehicle towed to the shop I had requested. When the shop pulled the codes they told me that my intake manifold and it would need to be replaced.
While driving, the check engine light came on and the vehicle started making a rocking nothing, did not know what was going on and so I stopped vehicle on the shoulder. I checked the gas tank to see if there was a problem with the cover. Went back in the vehicle and tried to restart, vehicle would not start.
Consumer states problems with gasoline leak and fuel gauge indicator while driving on a cold rainy day, gas fumes gradually filled the passenger compartment. The windows were rolled up and the heater was on at the time. Shortly after, the gas gauge indicator began to approach empty much faster than usual.
