    Pretty sure this car uses an additional battery for accessories.That may be going dead.I would take it to a shop that is equipped to work on Mercedes.They should have a Xentry diagnostic tool.(We have 2 here)Some settings may need relearning.

    Thank you for your response, I do plan on taking it to a Mercedes dealership. I also have a problem with squeak in the front when I hit a bump, I just wanted to have an idea of what I was looking at before I took it to the dealership.

    Thank you,
