What is your question?
When it won’t start, all lights etc works fine just doesn’t start. take battery cables off, let it set for a few minutes, replace cables then cranks fine. Maybe won’t be a problem for a few more times. What could be the issue?
What makes this problem better or worse?
I haven’t found anything
How long has your 2011 Mercedes-Benz S550 had this problem?
Just got the car a. couple weeks ago. Since I have owned it

Hello, Dave here, contributing to RepairPal and providing expert advice since 2010. No guesses here, unfortunately. Hands on testing when the failure is occurring is needed. If battery voltage and amperage to crank are sufficient as measured and the engine does not crank over, it could be a starter motor issue. But, I would not guess.
