Interesting thread.... This past Christmas I bought the new GLS63 for my wife. The car has less than 800 miles on it and it has been in the dealers shop for 4 weeks due to the "check engine light" being on. The first diagnostic was that "we" ran it low on gas and sucked air into the fuel line. Interesting since we had only put two tanks of fuel in it and the fuel level has never been below 1/4 tank. Further diagnostic by the dealer now indicates miss fires on cylinder #1. They replaced the injector and still no remedy for the "check engine light". Currently they are smoke testing the turbos (not sure what that means). I am remaining patient for a another week if it is not resolved, intend to ask for my money back and they can sell the GLS63 to the next sucker.
As far as Mercedes and quality, my opinion is that they are HORRIBLE! My wife has driven Mercedes for the past 23 years. We alway buy new and everyone of them has had more than normal repair issues ranging from failing fuel pumps to replacing an E63 engine at 15,000 miles due to "porosity" in the block casting. Hoping this instance is good enough to get my wife to consider another brand vehicle.

The "turbo smoke test" likely involves connecting a smoke machine to the intake tubing system of the turbo and pressuring to check for boost leaks, which can often cause all sorts of unpredictable ignition issues (i.e. cylinder misfire).
I haven't checked any "data" but the general feeling I'm getting lately is that a higher percentage of the AMG GLS models are not right from the factory. Wondering if it's because it's technically a first year for that model.
