I have a brand new C230 Kompressor sedan. Several times during the day, when starting out from a light or even just accelerating slowly, the engine just stalls out. It doesn't quit running, it justs acts like it has lost all power. It's a bit scary when it does that and the car behind me is still accelerating. The MB dealership cannot find the problem. I have it in there now for the third time! Apparently, it they don't see it on their computer, they are baffled. Any ideas? I have two of these c230's, so it's not anything about my footwork, etc. It's a very noticeable stall, as though you've taken your foot completely off the gas pedal.
