My vehicle is less than 3 months old and has around 2000 miles.
I walked in with the following issues
1, Check oil level message
Dealer response : Mercedes Diesel engines consumes more oil during initial break-in period .Oil topped off
2, Steering vibration at highway speeds
Dealer Response : Tires out of Balance . Tires rebalanced
3, RPM increases and decreases when steering is moved during idling
Dealer Response : This is normal in diesel cars as Power steering consumes some power when steering is moved resulting in RPM variation . No action taken
4, RPM raises when the truck is slowed down by applying brakes.
Dealer Response : Normal with diesel engines.No action taken
Overall no reliability issues .High mileage recorded 26.9 , Low mileage recorded 16.8. Average mileage with 2000 miles 21.1(Combined city and Freeway driving - 75/25)
That's all pretty accurate as far as I know. Mine went through 2 quarts in 10,000 miles. But when you stop to think about it, most vehicles change oil every 3,000 miles, so they would never see the loss. And we are carrying 2 extra quarts of oil. So even after the light goes on, you've got a long ways to go (a couple thousand miles?) before you reach the real low oil mark.
The increase in revs is really slick. I never knew that it was doing this until someone on this forum mentioned it. It's actually down shifting while breaking to add to the breaking affect (reduce pad usage) and make sure you are in the right gear to accelerate after breaking. This is awesome for city driving in heavy congestion. Great idea!
The power steering issue makes sense. It's just smart power management. I never noticed it. You are really in tune with your vehicle.
Good gas mileage. I was getting 22-25 mpg in a fairly congested drive for 20 miles and 5 miles of fairly open road. However I had a couple instances recently that I was hitting 29 mpg in less traffic. I'm over 10,000 miles now too. I've been told to expect better gas mileage sometime after 10,000 miles.
So the one surprise you wouldn't have seen yet is the puff of white smoke lasting 10-20 seconds. I hear it happens sometime after 10,000 miles, depending on your driving style, conditions, etc. It's a self-cleaning exhaust system. Another slick Mercedes idea.
I'm thrilled with the technology in these vehicles!

35,000 miles on mine; and I've never seen any white puffs. Maybe they didn't include that technology in mine.
I do, however, do regular pedal to the metal accelerations on freeway on ramps to help clean out the particle filter. (PS - If you don't do this once in a while, I've been told that you will "coke" up and restrict the flow in that filter.)

They are self cleaning as periodicaly engine systems change the fuel/air ratio for a bit to create extra heat in the exhaust system to burn out the trapped particulates.
If your particulate filter plugs--and you can prove you've used correct fuel and motor oil--it will be replaced under the 8-yr/80K mile emissions warranty.

Just turned 2700 with our 2008 ML320 CDI. Had it in around 2,000 miles for first service. No issues repaired. We do have a creak in the windshield area, in our old one it was the plastic air intake vents. Of course, it didn't creak the day we had it in. No oil usage of note. Mpg: 34+ on a trip with long stretches of road and flat. Overall average at 28.7 with about 80% open highway. It was a little spooky putting in $95.50 of fuel but with a 700 mile range it is almost 1.5 times the mileage and 1.7 times the range of our 2000 M-Class.
