Check Engine Light On problems of the 2006 Mercedes Benz ML350



Ten problems related to check engine light on have been reported for the 2006 Mercedes Benz ML350.

car   Check Engine Light On problem 1
Failure Date: 01/21/2014

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. 00 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. 00. 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.

car   Check Engine Light On problem 2
Failure Date: 07/02/2013

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.

car   Check Engine Light On problem 3
Failure Date: 10/19/2012

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. 00 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. 00. 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.

car   Check Engine Light On problem 4
Failure Date: 02/02/2012

Owner of 2006 Ml350 check engine light came on took in for diagnosis with cam shaft failure, mb does not offer any help and knew of this issue. Class action lawsuit in NJ already started, hoping one will get started in SC. Cost to repair is $6,000 to the customer. This is usury, and deception by the wonderful automakers of this great foreign car maker with an office in the USA. When you call mb USA they advise you to speak with the service manager that offers no help.

car   Check Engine Light On problem 5
Failure Date: 09/01/2011

Around 45,000 miles the check engine light came on. I took the vehicle to a Mercedes Benz dealer service department and was notified that the balance shaft needs to be replaced. In order to replace the balance shaft, the engine needs to be taken out of the vehicle and taken apart. Estimated cost $6,000. The service dept. Told me that it was due to a part that was not hardened properly during manufacturing. There is a technical service bulletin (s-b-03. 30/08i) that was originally issued in 2007 which was found in internet searching, however it seems like Mercedes Benz knows that the check engine light (on the majority of these vehicles) will not come on until when the warranty has expired. Since this fix is a huge expense, they are not going to issue a recall even though it is clearly a safety concern. If I would've have continued to drive the vehicle in this condition, eventually the balance shaft would have continued to break its teeth resulting in engine failure. Continuing to drive the vehicle in the condition is not safe, it is a matter of time before the vehicle stops running and the engine would need to be replaced. The Mercedes Benz USA replaced our balance shaft or pay for it people who already fixed.

car   Check Engine Light On problem 6
Failure Date: 08/26/2011

Balance shaft problem on the 2006 Mercedes Benz Ml350 - I live in south FL and I have a 2006 mercedes Ml350 with less than 50,000 miles and just last week got a check engine light. Took it to the dealership in pompano beach and they told me that the balance shaft has to be replaced and it will cost $6600. This is a known problem and the manufacturer makes no effort to recall the vehicles and replace the parts for free. I cannot afford to pay for this factory defect, Mercedes Benz should pay for it.


car   Check Engine Light On problem 7
Failure Date: 05/20/2011

I am the owner of a mercedes 2006 Ml350. I have had my cam sensor and crank shaft sensor repaired 3 times since I have owned the vehicle. I initially had my car serviced at park place in dallas on lemmon avenue. My check engine light is on again after having this same issue reparied several times. I can no longer afford to keep repairing for a problem that is going to continue to cause problems. After having these items repaired I took my vehicle to get an inspection and I failed the inspection. So I took it to a mechanic and he told me that my balance shaft gear needs to be replaced which is the reason for my sensors to continually wear out. This repair cost $6000. 00 and I cannot afford it. My check engine light has been on for months and I have an expired inspection sticker because I cannot afford the cost of this repair.

car   Check Engine Light On problem 8
Failure Date: 05/18/2011

On may 18, 2011, I took my 2006 Ml350 to an authorized mb dealer due to the check engine light indicator being illuminated. The vehicle was diagnosed with the balance shaft failure. The cost to repair is approx 5k.

car   Check Engine Light On problem 9
Failure Date: 01/01/2011

I own a 2006 ml mercedes-benz with 47k miles. The engine light came on in the car, I had it checked by an independent mercedes technician who informed me that the balance shaft must be replaced in the car. He gave me a "star bulletin" which is an internal memo produced by mercedes showing the have known about this defect since August 2007 and have done nothing about notifying owners of the cars with engines effected. It is I have been told a common place issue and in fact a class action lawsuit has been filed in new jersey against mercedes over this issue. The problem has to be repaired or the engine can be damaged beyond repair, the cost I have been quoted for the repair is $6000. It was made very clear to me by the technician that a car with 47k miles should not have such an issue and that it is a design flaw that mercedes thus far has not stepped up to remedy with car owners.
