I have a 2011 S550. I know for sure it sat for weeks without use prior to buying it and had "hard starting" reported. I have a recurring "dead battery" like failure where the car won't start. Dealer has been good, but baffled. The main battery, starter, alternator, regulator, and several modules have been changed.

When the dealer gives it back with a good charge, its weeks before it has the issue, then it fails to start 3-4 times a week. Jump it, drive it, starts for a few times, then fails again.

This past time, the car was dead. Turn the key fob, no dash board, and very few clicks. When the roadside tech connected the portable jump cables, the car fired right up like there was no battery issue at all.

No one knows what to do.

Any ideas? Anyone know if the battery control module might cause this? Other component that on command to start could be shorting the battery?
