My car has stalled several times, either when I am driving, or when I stop at a traffic light. Rough idling and/or running when stopped at a red light or driving at speeds that wouldn’t normally be an issue. Engine stalling or misfiring, and car sometimes have trouble starting up. Loud rattling or vibrating noises from the engine. The check engine light is turned on. I took it to Mercedes Benz Dealership in Brooklyn, NY and was told it is a Balance Shaft problem, and they told me it could cost me about $9,000.00. Further research informs me that the problem should not be ignored, nor repair put off. Also, that failure of the balance shaft leaves the inner components of the engine unsecured and therefore will ultimately result in damage to the engine if left unchecked. Also, that driving at high speeds for long periods can agitate the problem even further due to the constant vibrations without a proper securing mechanism. As a result, I parked my car for several months, since I cannot afford the amount they quoted. In essence, I cannot even enjoy the car I bought.

Takata recall. I purchased my 2006 mercedes r350 in 2016 with over 100k miles on it. With the engine light already on. I used a scanner tool for an accurate diagnosis. As it stated two issues. A crank shaft sensor/ cam shaft sensor was needed. So I decided against my better judgement to finalize the purchase anyway. Needless to say, after I changed the sensors the problem still remains. After doing a lot of research and spent unnecessary money, it was brought to my attention that the problem is in fact a faulty balance shaft inside of the engine. Due to a manufacturing default. That was covered my mercedes in a recall at one point before I had purchased the vehicle. For something as serious as a defected part in a motor should not be limited to when you purchase the vehicle, but whenever it is brought to their attention it should be repaired without hesitation since this is a manufacturing default and not something that was done by any previous owners. I would like to know what if anything can be done to help me resolve this issue at hand. Thanks in advance.

This is a well documented issue but mercedes benz refuses to acknowledge the balance shaft as a defect and road safety hazard. Unfortunately it's going to take someone's engine falling a part at high speed causing an accident before someone will do something which is terrible. Mercedes-benz balance shaft problems and how to check your car. Balance shaft mercedes v6 and v8 problems mercedes-benz v6 and v8 engines had timing chain problems caused by balance shaft and idler gear failures. Mercedes produced certain models with defective gears in their balance shafts (m272 engines) or with defective idle gears ( m273 engines). These faulty gears wear out prematurely, excessively, and without warning, causing the vehicle to malfunction, the 'check engine light' to remain illuminated, and the vehicle to misfire or stop driving.

My engine light came on - took the car for repair and was told p codes 0016 and 0017 were coming on meaning there was a defective gear in the balance shaft which mb knows about and refuses to take responsibility for. It would cost $6000 to fix. I began to look on the internet to see if any recalls or issues like mine have occurred with others and I found I was not alone and a class action lawsuit had been filed. I want to file a formal complaint as mb should be help accountable for knowingly providing faulty products to customers - they need to be liable to recall and fix every engine affected by this!! The us government needs to protect consumers better than this!

Engine balance shaft wears excessively to the point where some teeth are almost gone. Causes check engine light to come on and excessive knocking as affects ignition timing. Repair is extremely expensive as it requires taking the engine out. If left unfixed it may stall the engine during driving and be a safety hazard. Research on the issue online shows potentially this issue affecting a large number of vehicles using the same engine.

I began to look on the internet to see if any recalls or issues like mine have occurred with others and I found I was not alone and a class action lawsuit had been filed.

My engine warning light came on. I was told that the strut had gone bad and the cam in the engine went bad. I was told by the dealership that is normal in the 06 r350 and they are not sure why it hasn't been a recall. Im upset because im viewing your website and other sites that are design for other owners with the same vehicles and they are showing the same problems.. What will it take to get a recall on this before someone gets hurt.
