Vehicle has just over 31k miles. ON multiple occasions, the vehicle randomly shuts off and displays a 48 volt battery error on the screen followed by a check engine light. This has happened in the middle of a busy intersection and at 75mph on the interstate. Each time it does this, I have taken it to a Mercedes dealer for repair/troubleshooting. THey perform the Mercedes required steps to repair the known issue and each time the issue persists. The car has been at a dealership for almost a combined 30 days now with no end in sight.

I am not prepared to drive to *another* dealership and ask *again* to get this done. I own the car and the previous owner can do whatever they like with it. Unacceptable.
