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. 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.
As I was driving down the highway I pressed on gas pedal and vehicle made a very loud chain whine noise and it cut off in the middle of highway and never started back up.
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.
Balance shaft gear defective apparently Mercedes has been aware of this problem, class action suits have been filed- no recall yet. I plan to call Mercedes dealer tomorrow- do not anticipate any help on their part - if that's the case will try to join class action suit as this is a known and very costly -(thousands of dollars) problem for numerous mb vehicles- many classes from 2007 -2011. Mercedes Benz was apparently aware of this defect when I purchased my vehicle (used) from local mb dealer here in NY 2009 as a pre owned certified vehicle, why was I not made aware of this issue that Mercedes knowingly knew and come to find out a class action lawsuit was filed. The NHTSA need S to look into this many complaints have been filed, Mercedes service techs were made aware of this issue but they were not instructed to let customers be known of this when cars were brought in for service. Please look into this and recalls must be preformed
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.

The contact owns a 2006 Mercedes Benz R350. The contact stated that while reversing, the vehicle made an abnormal noise as the steering wheel seized and smoke started to emit from under the hood. The contact turned the engine off but the vehicle failed to restart. The vehicle was towed to an independent mechanic. The technician diagnosed that the power steering pump, serpentine belt and idler pulley needed to be replaced. The vehicle was repaired. However, the contact stated that the check engine light stayed on. The manufacturer was made aware of the failure. The approximate failure mileage was 130,000.
While I was driving, I lost power steering. I had to pull over and saw that my engine belt was off my engine and a pulley came off my engine. This is after the dealership had already replaced my belt just less than 10,000 before. It was a good thing that no one was hurt. It seems like this engine is defective and Mercedes Benz refuses to fix the problem. I'm afraid that someone who does not know how to handle the loss of power steering will be in a fatal accident.
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.
The car rises up on one side when put thrust he computer no error code comes up. After a day or so sitting in the garage gets back to normal. Got it checked by mechanic no leaks. Then happened again they reset the computer charged me. Happened once again this time they changed the computer and the car showed airbag leaking. Car is out of warranty. Looked up on line mostly everyone who owns this car has this problem. This car has lot of issues. It stopped in middle of road on high way I was luckily saved but they said a shaft ring broke in the engine I had to pay $2000 dollars. Mercedes should recall R 350 for suspension leaks.
My engine light came on and my car began to idle really high when parked or at a stop in October. I went to two Mercedes dealers to check on the issue. The second Mercedes dealer/service center validated the first, explaining it was the engine balance crankshaft that was loose in the engine and 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.
