Actually there are many similar problem, MB even issued few technical service bulletin for this matter.
If the dealership won't help you, try to call MB of North America and se if they will offer help. 1 800-267-6372, 1 201-573-0600, make sure you will have the VIN# at hand.
Document everything from now on, ask all diagnostics to be printed, all estimates, just everything on paper. Beside the phone call to MBNA write a claim also, and ask for written response. You might need these in the future.
Ask investigation from NHTSA. http://www.nhtsa.gov/
I'm surprised no one started a class action as of yet.
Their quality went down a lot in the past 10 years (just like VW/Audi), and I don't think it hit the bottom yet.
Let us know what happened, so others with the same situation might be able to join you.

My engine light was constantly coming on, and they told me the CAM sensors need to be replaced ($300)I also have a whining sound, and my transmission needs to be replaced! Only 77k on it. Apparently this is a common problem with an 2006 and earlier.

Same problem - dropped my car off at the dealer yesterday and they asked for all my service records. The service rep. hasn't returned any of my calls, i just spoke with the service manager and expect a call back in an hour. More will follow...

Having same issue as I write .... 52,000.00 miles ... balance shaft went out... dealer took care of it because it was only 2,000 miles out of warranty.... got the car back... transmission acted up .. took it back... wanted to charge... refused to pay as the car was running perfect until the engine was pulled to fix balance shaft... still not running properly.... said it was not what they did.... did not want to pay for the repair.. basically said there will be more problems with the vehicle even after it is repaired.... have a call into MB but spoke with the dealer again... he agreed to pay for the repair to keep a valued customer...BUT basically said the car will continue to have problems... all because nof the balance shaft issue....
Any more information?

I'm in the same boat as you. Hard to believe that MERCEDES BENZ of all companies wouldn't stand behind their product. And apparantly they've known about this problem for a while. There is a Facebook group that is in the process of filing complaints with the NHTSA. Then a media blitz.

Yes I'm having the same problem w/ my ML350. I took it to the dealership they had it for 1 hr 50 mins, the service advisior stated that it will cost for the parts $1200 and for labor it will cost $6000. He also stated that they would have it for 3 days with a loaner my check engine light was on for 2 weeks it had no noise. When we declined the work to be done, I left and as I'm coming on military base it was making a very loud noise. When I pulled into my driveway I could barely turn my wheel.
