| Description of the problem | I purchased my car brand new, it was never previously owned and directly from a mercedes benz dealer. I started having problems with speed and gear shifting back in may 2012. When driving on the freeway normal speed (55mph) the car would begin to slow down no matter how much i pressed the accelerator the car would slow to a complete stop. I would have to attempt to pull over off the freeway, turn the car completely off, let it sit and then start it again and the car would run normal. When i get off the freeway or now even when i am driving on a back road going 35 mph the car would shake as i came to a stop sign or traffic light (as if i was driving a stick shift and didn't put the car in neutral or press the clutch) and then it would shut down completely. Now i am having a third issue in addition to these issues where the car will shift gears on it's own and i'm driving in automatic mode not as a 5 speed. This is completely ridiculous for me to have transmission issue on a mercedes benz that i purchased new. I took it to a dealer who claims that i have to replace the entire transmission due to one small piece within the transmission system. I have checked online and have seen that hundreds of other benz owners are having the same problems with no resolution from the manufacturer. I am requesting an investigation and a recall. This is an extreme safety hazard that a car will completely shut down while on a freeway and there have been times when i have almost collided with other cars due to the immediate decline in speed. I have to always find a way to pull over to shut off the car. I purchased this car because of the quality that it should provide. Please follow up with me regarding this issue i am extremely concerned that requests are being ignored by the manufacturer and no one is looking into this matter. |
