Two problems related to engine have been reported for the 2006 Mercedes Benz ML350. The most recently reported issues are listed below.
2006 mercedes Ml350, balancer shaft worn at ~75000 mileage. Balancer shaft gear and/or camshaft chain got totally worn, that will lead to engine lockup at any time if not fixed. I hear similar complains from other mercedes owners with m272 and m273 engines manufactured in 2006. There also is internal mercedes technical service bulletin s-b-03. 30/08i from October 24, 2008 for this issue. Also there is a class action complaint case 2:33-av-00001 document 9629 filed 10/05/10 in NJ us district court. Based on my past experience as engineered, I conclude premature balancer shaft wear caused by mb supply chain issues (I. E. Bad parts). Issue on my car have been diagnosed in 06/2011 and I have been offered a repair for 5 different issues (pretending balancer shaft fixed for free) with labor charges shuffled around to mask balancer shaft issue. Total repair bill is around $10000 which is full price amount for all 5 issues fixed.
2006 Ml350 Mercedes Benz - balance shaft needs to be replaced in a car with under 50,00 miles on it. They want 8,000 to do the job and I am finding more and more people who are having the same issue with this car. I was directed to you by a facebook site that is for people who have the same issue with their mercedes. I think this is a flaw in the car and they should be recalled.
