What owners wrote

My wife was driving my ml350 on the freeway with my 7 year old son in the back. She said the vehicle started to shake in an unusual way so she decided to get off at the nearest exit and when she applied the brakes on the off ramp the car's engine stopped. Engine light came on, dash read inoperable yet all the electrical was still on. She tried to turn the key and restart it but the car would not start. Before this incident we had not experienced any problems.

After being into authorized mercedes benz dealership only for an strong diesel fuel smell and oil leak 3 times in less than 4 months on our ml350 bluetec engine fuel smell is strong enough that we have a sever headache ,nauseous feeling and have to stop the car and get out for fresh air, opening windows only gets more of the smell in of fuel and burning plastic. This happens while vehicle is in motion ,both on city streets and on highways, more pronounced when driving.
