One problem related to car stall has been reported for the 2012 Mercedes Benz CLS550. The most recently reported issues are listed below.
When started and for some period after warm up the engine fuel injectors rattle. The dealer mechanic claims that this is the result of the split rail system installed on the engine. This makes the motor appear to be knocking as the noise is loud. I have reported it several times since 2017.
