Automatic Transmission Problems of BMW 335

My vehicle is 2007 BMW 335i. On 7/3/11, I was on the interstate going 70 miles per hour when the engine warning light "engine malfunction- reduced power" was activated causing the vehicle speed to abruptly reduce speed to around 20-30mph. I had to activate hazard lights and limp off interstate while car was bucking, coughing, and sputtering. It was extremely dangerous as the sudden slow down might have happened on a busier interstate. I called the tow truck and had the vehicle towed to a BMW center where they claimed they removed some sand from the throttle body. BMW wanted to blame the high pressure fuel pump, but realized it was replaced 3 weeks earlier due to a recall, along with an "updating" of the engine control unit software and replacing some injectors. I never had a problem with engine until after these recall "fixes. " the care now loses power and has turbo acceleration lag. These same dangerous engine issues have happened another 5 since the "fix", only a month ago. This is a known BMW defect! this very same issue appeared quite often to a number of 335i or other BMW models using the same engine, in particular to the 07 and 08 models. Many car owners have the same issue happen after their fuel pump was replaced once or even twice. It seems like there is no fix for this issue and it poses as a tremendous danger for BMW drivers with this specific engine since you cannot be certain when the problem will re-occur. A class action lawsuit was filed recently in California regarding these same issues. Will someone have to die before the government holds BMW responsible?.

First time about four month ago when I was driving, the car suddenly had check engine light on and lost about 50% power. Next day I took the car to BMW dealer and the cil was gone. They said everything was fine. Today when I drove on hight way at about 65 m/h, cil on again and the car loss power, I think there is a safty issue with this car.

I have a 2008 BMW 335xi. It has a serious transmission problem. When I am at the red light with my foot on the brake it feels like someone hit me from behind! so hard I look in my rear view mirror to see the car that hit me and get out to get their insurance info. BMW will not fix it saying that the tech cant reproduce the problem! if my kids or your or some driver with not alot of experience would have this happen to them I assure you they could panic and hit the gas and end up in the intersection and get killed!!! something has to be done before someone dies!!!!.
