On 8/26/14 I was stopped at a light. When I went to take-off, the car would not accelerate. It finally did but very slowly. This occurred two more time at the next two stop lights. I was then in a center turn lane to turn across three lanes of traffic & when I tried to accelerate, the car died and the electronic display gave a yellow error message that the car was inoperable due to an issue with the braking system. I immediately put the car in park, turned it off & then started it back up. Fortunately it re-started, the error message was gone & I was able to drive into my office parking lot. My Mercedes service dept. Said no codes registered on the computer, probably because I turned the car off so quickly it didn't have time to. Today, 8/17/14, I am having the same issue. My car is back at the Mercedes service department. This is, in my opinion, a dangerous & life threatening problem.

The gas becomes non responsive while driving and or have to stop the car restart it, the dealership states they could not find any problem this happened 3 times before and the last time on the freeway and was involved in a near miss with an 18 wheeler witch could have ended my life and possibly others on the freeway I am petrified to drive this car since then which happened a few days ago I took it back to the dealership and they are giving me the run around and claiming there is no problem with the car.this is a serious and dangerous problem I have herd from others that Mercedes car have this problem and trying to cover it up from the public.please investigate this problem before it ends up in a fatality, and then its too late. Every time this happens a message shows up on the dashboard and I took a photo of it they still ignored it I spoke to Mercedes they are investigating it and as yet did not contact me.
