Complete set of brakes 3 times.
Power steering pump hose.
Two Battery replacements.
Catalytic converter replacement.
Fuel pump failure.
Blown exhaust gasket.
Plastic wrap-around at both rear posts cracked.
Leather top on center console loose and ill fitting.
Off the line performance is exceptional for an SUV, I have never had to worry about being able to pass or accelerate.
General handling and ride stability are considerably better than many other vehicles that I have owned, including sport cars.
Fit and finish of the interior components has been ALMOST exceptional, with the exception of the aforementioned deficiency.
Service on the vehicle has generally been very good, our local dealership genuinely seems to care about customer service (imagine that!), I have gotten to know them quite well as much as this vehicle has been in for service.
And that in a nutshell is my biggest problem; after spending almost 50K for a vehicle, I do not expect to have as many service problems as we have had with this vehicle, and the main reason why I doubt very much if I will consider another M.B. I just put a deposit on a Lexus RX430 Hybrid (ten month wait as of now!) next year I'll let you know what I think.
