Hello. My 2011 E550’will not turn over. All the lights work. However, I did notice something last night where she almost stalled at a light. Then she was fine. However, when I turned her off, I got a weird message in dash ...correct tire pressure and then this morning after trying to start her,another weird message about S ( I don’t remember the next two letters) seat malfunction?? Any ideas?

Lights and function may still work but your starter needs a min amount of juice to even turn over. Sounds like the issue I had years ago.. Time for a new battery..
