Misfire of cylinder 2 and 6. I have a hard copy diagnostic report. It is better read than heard. I am weak. I have never enjoyed this vehicle since 2013 when I bought this car. Please help me. I pay $600.00 every month on this car as at today.

My engine light came on at 108,000 miles the error code P0016, replace the balance shaft gear, to replace remove the engine from the vehicle and take the entire motor apart, the dealer charges $7,000.00. The vehicle runs perfectly fine no engine noises, I look up the problem on you tube and the shaft balance gear wears out on all 3.5/ V-6 engines from 2006 to 2008 after 60 to 100 thousand miles. Mercedes refused to pay for the repairs or replacement engine. My vehicle lasted longer than 100 thousand miles because of the high quality maintenance that I have provided over the years. The mechanic said that it will break down without any more warnings, it will just quit one day like all others have done, because of a cheap gear place in the center of the motor which is very difficult to replace, the mechanic recommended to replace the entire engine with a 2010 engine, they corrected the problem in the 2010 models and some 2009, but to be safe only purchase a used 2010 engine.

The following is a letter sent to both Mercedes USA and Park Place Mercedes. Neither is willing to stand behind their product. You be the judge: I am writing in the hope of seeking assistance on a quality issue with my 2006 Mercedes R350. The car has 63,711 miles and has had all recommended service performed at the suggested mileage, including regular oil changes every 4,000 miles (synthetic oil). In October 2012, the car was put in for service at Park Place Mercedes because the engine started making “ticking” sound when running. Park Place Mercedes indicated the problem was due to a pulley, which they replaced at a cost of $620.00. Upon retrieving the car, I noticed that the service performed did not resolve the ticking sound. The Park Place Mercedes mechanic was called for a consultation and informed me that ticking sound was “normal and there was nothing to worry about”. Of course I did not agree, as the car had not ever made the noise a week prior, but I was unable to convince anyone at Park Place Mercedes otherwise. I continued to drive it as suggested. In December 2012 the oil was changed at the dealership, and the ticking continued. Then in January 2013, while on a rural road traveling at the posted speed limit of 30 mph, without warning, the check engine light came on and the car immediately stalled. There was not even enough time to pull off the road. Not drivable, the car was towed to Park Place Mercedes where it was diagnosed that pistons in cylinders 1 and 4 had come apart, requiring a complete engine block replacement. The cost of repair was quoted at $15,000.00. The value of the car, prior to the catastrophic event, as listed on Kelley Blue Book is $17,000.00 private sale. After repeated calls to both Park Place Mercedes and Mercedes USA requesting assistance, each denied anything unless I was willing to purchase a new Mercedes. Their “goodwill” was to only allow me $2,000.00 toward a new Mercedes. Park Place Mercedes recommended that I not pursue fixing the car and that I should seek a salvage value for the car, which was estimated between $2,500.00 and $3,500.00. This would leave me at a loss of approximately $13,500.00 and $14,500.00, which is completely unacceptable. My expectation is that an engine on a well-maintained, well-cared for vehicle should last beyond 63,711 miles, especially on historically trusted, luxury vehicle, unless there are issues with quality of parts used, or the quality of the construction of the engine. Desperate for information that the dealership could not or would not provide on what may have caused this problem I turned to the internet for answers. I found an astonishing amount of complaints and issues related to this same engine. I can hardly believe it is safe enough to put our families in a vehicle with so many problems. I believe that Park Place Mercedes misdiagnosed the ticking sound that ultimately led to the engine failure. I feel strongly that Mercedes USA should stand behind their product that we purchase with hard earned money. Their treatment and lack of response to a customer whom has trusted in their product and history is shameful. They should recognize the issues with this engine and compensate those who trusted them.
