Twice within a year a "48 voltage battery malfunction" warning appeared on my dashboard. Then a red warning light appears and I had about 30 seconds to find a safe place to pull over as loss of power causes deceleration of the vehicle . The cause, according to the diagnostic test performed by 2 different Mercedes dealerships, is that a software update is needed. A know of no situation where the machine crashes first then you're told to update its software. I am concerned that this will unexpectedly happen again and possibly on a road where pulling over to a shoulder may not be possible in the little time given before power failure.

I was driving the car on a road I drive daily with my son in a child seat in the back row. The car inexplicably slammed on the brakes at full force, stopping in time to avoid driving over the shadow of a tree. Approximately thirty minutes later, there was a loud popping / explosion sound from inside the engine compartment, the car lost all power, coasted along for approximately 100 feet, and then restarted while coasting. This is the second time in under a year that the car has experienced a major electrical system malfunction.
