48Volt battery failed after three months and just 3,400 miles. I understand this is a recurring problem with Mercedes. Car had to be towed as the vehicle was totally inoperable due to battery malfunction. It took more than three weeks for Mercedes to provide a replacement battery. From what I have read, there is a strong likelihood that the battery will fail again.
