With our 2005 300C we had a random, intermittent stall problem. Generally, from a stop for a traffic light or turn signal and the stall occurred when you tried to accelerate. More often than not it was during a turn when the stall occurred, but many times it was just straight acceleration from a stop.
You had to let up on the throttle, allow the engine to catch and continue. No dealer every found a problem or resolution.
Very concerning as you never know if the power you need will be there or not.
