general problems of the 2014 Mercedes Benz CLA250

I just got the vehicle it’s losing power already, I was driving up a hill as a school bus was behind me, and my car started losing power and rolling back. I have a transmission issue they sold it this way also electrical.

Was driving on a road with 3 lanes . I was in the right lane was switching to middle when my stering and brakes just locked up I was not able to control the car I ended up all the way in the left lane crashed into a car and ended up on the divider.

The breaking system has gone out on this car while driving three different times. It's extremely scary and has almost caused an accident each time as there is no warning when the system fails. One minute the car is fine and the next you cannot stop. No way to know it's about to happen until you press the break pedal. The first time we had it fixed from the mechanic he seemed to believe it was a fluke the break booster part went bad so we fixed it. Second time we returned to the same mechanic and he said the entire system failed and replaced all the parts including the booster. Except this time he was able to exchange the booster under a part warranty. Now in the last few days the entire system failed again with no explanation. All three instances have happened in less than a year. There is obviously a design flaw in this car and it's extremely dangerous and we do not know what to do. We got lucky not having an accident as well as some of the second and third repairs being under a parts warranty. There currently is not a recall we can find for our model but if you look up other mercedes models they have a break system failure recall. This needs attention!.

As I was driving on the highway around 65 miles per hour, the vehicle's check engine came up and said " inoperative, pre safe inactive" I freaked out. I was at highways speeds and it was inoperative. I noticed that the power steering was affected and the vehicle was unresponsive when I accelerated. The abs system was disabled, I was scared even to brake because I know that when the abs system is disabled the brakes can lock up and cause an accident, injuries and even death. I have noticed that many Cla250 owners have the same problem.

I purchased a new new new mercedes cla-250c automobile late September 2013. In mid-October I experienced un-commanded acceleration to above 5500 rpm. This ceased just as I was about to apply braking. The car then behaved normally. On christmas night I experienced un-commanded braking whenever I backed off the accelerator pedal, the force of braking being proportional to the degree of lift-off from the accelerator. I was able to bring the car to a complete stop without touching the brake pedal. At that point I grounded the car. On January 7, 2014 I informed mercedes-benz about the above. I am prepared to provide further information regarding the above events and my correspondence with mercedes-benz USA should you desire.
