I have a Mercedes Benz ml- 350 year 2011. The vehicle has a little over 60,00 thousand miles. The engine light from my dash board started coming on. I brought the car in to the Mercedes dealership for a diagnostic test. The test results indicated there's a problem with the balance shaft. The repair quote I received was $9,300. This is quite absurd... to say the least ! as I researched this issue regarding the balance shaft this has been an occurring problem in the ml- 350 and C class models such as the C 220. (V6 272 engine) there are noted class action suite's going back to the ml- 350 2006 up to the ml-350 2010. The Mercedes Benz corporation has showed only reluctance in repairing this prevalent problem. There position as stated this issue was rectified from the 2010 recall. Obviously the problem with the balance shaft in this ml - 350 model has not been resolved. My next step is to approach the Mercedes Benz corporation again for a final decision in resolving this issue. If they don't take the responsibility in standing behind there product and keeping their reputation in good standing I have no other choice but to pursue this as a legal matter...
