The car stopped accepting the electrical charge, whether it was with the 110 or 240v. The entire charging system failed. Mercedes-Benz repaired the problem beautifully, but it took 3 weeks without the car - reason (and I'm really cool with this), was this must have been a first for the car/brand. The part was ordered, which took some time, and then the tech was having to call back to Germany to get folks to "help" fix the issue. I have to state they did a very thorough job - but it was a long repair. I asked if I got a new car (joking), and the statement was probably better than the original. But, I'm glad the car was still under warranty.

Additionally, the car had a safety recall with some kind of bolt in the steering wheel, that after the repair required an alignment.
