When accelerating hard, the car looses all power and goes into 'limp mode'. this is a extremely dangerous position to be in. If you're on the highway with a cement wall right next to you and everyone is going well over 80 and you loose all power, you're a sitting duck. There is no way to make it across 4-6 lanes to pull over, turn off the car and wait 20 seconds to reset and start again. I have seen many complaints on forums and Mercedes is denying the issue. It's a well known issue and needs to be recalled and fixed. This issue has been going on for 4 years now and no help from Mercedes. This has happened numerous times with the first time happening in 2015.

I backed the car out of the garage at my condominium building in sarasota and placed the car in park to remove something from the windshield (I believed the car was in park -- but it could have failed to engage it or I possibly nicked it on my way out of the car). I started to move out of the car, while my right foot was on the brake -- about 90% of my body weight was out of the car and then I took my right foot off the brake. The car started to move backwards and I was sandwiched between the left front door of the car and the car itself -- I dove to the ground to avoid being hit by the door, injuring my left side -- and then I rolled on to my back to avoid the door and then saw the left front wheel heading for both legs -- I tucked and dragged my body away -- the car passed by, missing my two legs by only an inch or two. The car crashed in to the fence of my condominium building. After talking with Mercedes Benz usa, I learned that the car did not have an automatic park feature -- but if I had purchased a keyless go feature, the electronic transmission would have had a feature that would have caused the transmission to go in to park as soon as the standing vehicle door was cracked. No one at my dealer and no one at mbusa service knew that this feature was available -- and then only if the buyer had purchased keyless go. This feature should be on all electronic transmissions from mb -- at a minimum, dealers and prospective customers should have been made aware of this missing safety item and its availability as an extra. Mbusa has told me that this feature cannot be added to my car -- it is only available at the plant of manufacture.

I was pulling into a parking spot at my health club. As I was about to stop, my vehicle suddenly and violently accelerated going into the curb, up a dirt berm and over some very large boulders. I never made it over the berm because the car got lodged onto of a large rock. When it was over, it took a couple of seconds, I know that my foot was pushing hard on my brake. However, I doubt that would have stopped the car. I will report this to Mercedes Benz, have it checked, but I am not optimistic they will find anything wrong.

The turn signal lever and cruise control lever are too close together and dangerous. Activated cruise control too many times in error. Not good engineering. To correct it they can take out the current cruise lever and put in a shot stubby one or extend the turn signal lever which would be harder as it controls the w/S wipers also. It can be corrected and needs immediate attention. Going to result in a serious problem from accidents. Needs immediate attention!!!!recall necessary. When it happens car speeds up!!!!!!!!!!!!!
