Battery Dead problems of the 2004 Mercedes Benz CL500

I purchased this car June 2016. Enroute to vacation, in early August, the driver side electrical panel stopped operating. Mid-way to vacation, while stopping for gas the instrument panel when completely dark. I was unable to gauge how much gas, speed, etc. , also at that time while sitting in the car, the jumped as if someone hit the car. Later I learned that it was the suspension. This continued to happen throughout the vacation. Upon reaching my vacation destination, the next day the car would not start and I had to call to get my battery jumped. Two days later the battery died again and I had to call for a jump. After returning from vacation, a week later, the battery died again and I had to call for a jump again. In my opinion this car is not safe to drive. I reached out to the recall representatives and was told that the instrument panel is not under recall.
