Took my vehicle to the dealership for check engine light. My registration is up next month and need to smog. It won't pass with check engine light. Dealership says its timing gear/camshaft issue and it will be $7500 to repair and its dangerous to drive. The service advisor said Mercedes would be willing to pay 25% of parts for the repair which would be around $500. This I thought was strange so I looked it up online and their are hundreds of stories and a couple class action lawsuits regarding this same issue for this engine. Mercedes Benz obviously knows about it and should recall it.

ML350 6-cyl

  • 80,000 miles


I was on my way to pick up my spouse from the airport one night without warning the vehicle started making a rocking motion and the orange check engine light came on. I pulled over, turned off the engine and exited the vehicle to see what was wrong, I re-entered the vehicle and tried to re-start the vehicle but it would not start. I called Mercedes Benz and they proceeded to have my car towed to the shop. I waited 4 months for them to assist me in fixing my vehicle since the warranty has expired and I have no extended, they refused to assist me even though they told me that the manifold had broken off and may get into the engine and that I may need a new engine of which I ended up purchasing a low mileage engine. Prior to this I paid $1500. For them to fix 2 leaks on my power steering and as of now my vehicle is leaking oil and making that same loud noise as before they fixed the leaks. I have been very very upset with them, my vehicle has been giving me too much trouble for not having 100 thousand miles. Please help. I call their corporate office and even wrote a letter to them and all they offered me was $2000 towards the purchase of a new vehicle, you may think that a Mercedes Benz will be able to do better that for their customers. I was lied to by them pertaining to the engine, once I was told that the engine was bad then I was told that it was not bad. I took my car from them and took it to an independent car repairing.

ML350 6-cyl

  • 143,000 miles
My check engine light came on and I took the vehicle to a local Mercedes dealer, and the tech told me that the balance shaft was the problem and that it will cost me about $8000 to fix it. He also said that there was no manufacturer warranty to fix it. It took the vehicle to independent mechanic who fixed the problem with about $7200. I researched the problem and found out that is common problem with the make and model, and there is a pending class action suit in NJ against Mercedes usa. I contacted Mercedes usa in August 2013 about reimbursing me the cost of repair, but the manager I spoke to denied the request. Action requested: I am seeking the help of NHTSA in recovering my cost of repair.

ML350 6-cyl Diesel

  • 109,458 miles
My check engine light came on about 24 June 2013 or so. I contacted atlanta classic cars, my local mb dealership to address the issue. My vehicle was inspected on 2 July, and the report indicated my balance shaft needed to be replaced ($5,100), my power steering components needed to be replaced ($3,067.50), and my transmission valve body needed to be replaced ($1,812.95). I have been the sole owner of this vehicle, and have had it serviced regularly at mb dealerships (critz - savannah, ga and atlanta classic cars - duluth, ga). Previously, this vehicle had transmission problems, which occurred just after the warranty expired. At first, atlanta classic cars did not want to take responsibility for the issue, since the vehicle's warranty had expired. After my husband got involved, they agreed to fix the problem for no charge. Another minor problem involved the locking mechanism on the vehicle's hatch -- it had to be replaced three times before it finally worked properly. I am very dismayed that after seven years and 109K miles, my vehicle is experiencing such expensive problems as this.
