The battery located in the trunk of the vehicle is situated next to the gas tank. There are no covers on the metal parts on the top of the battery located in the trunk of the vehicle, and the mat that comes with the vehicle does not sufficiently cover these metal poles, leaving them vulnerable to catch flame when metal items are in the back of the vehicle. The rear battery caught flame, while stationary, due to a metal rod used for furniture assembly touching the exposed portion of the battery.
I have approximately 104,000 miles, I cannot see it anymore because while driving home at night from the airport on the expressway doing 65 miles per hour, it went black. All the gauges were found stuck in their location the next morning at what they were at when the cluster went black. The cluster has never recovered and I have to drive with no idea of speed, signals operation, fuel level, or water temp. The information display is also blank so I don’t know what my mileage is or if the vehicle has any other information to give me. I had to drive home 60 miles in the dark. My headlights go on all by itself whenever I start my car now. My climate control also remains lit and causes a battery drain over a period of time. I was very lucky to make it home but now I can only drive during the daytime until I can get my instrument cluster repaired. …

While driving on 12/10/2016, the instrument cluster panel went very dark. At night there was no illumination either. Also the speedometer was fluctuating wildly from high to low and back.

The gear shifter had locked initially out of the blue, I couldn't get the car out of drive. I turned it off to stop it and then it wouldn't go into park. After the Mercedes tech came out it wouldn't start at all. The tech said it was most likely a safety feature which had kicked in. Then the whole right side went down. I am told the airmatic suspension went out. Why? The car said stop airmatic to low. I have never had any problems which May have lead up to these issues. Unfortunately I can not afford the $2,000 to repair this issue with the airmatic. Is there any kind of recall on this vehicle or warranty with Mercedes that is responsible. The electrical problem is the radio going out for 2-3 months and then coming back on out of the blue. The door open signal not going off in the alerts. The trunk switch not working to open the trunk, it can only be opened manually. …
