general problems of the 2008 BMW M3

I have a BMW e92 chassis. I have spoken to many, many owners of the same BMW and they have said the same thing. The throttle body actuators are defective on these Bmws. When the malfunction takes place the BMW goes into limp mode. The car is not able to rev above 3k rpm nor go a speed of over 55 mph. This is incredibly dangerous on the interstate when your car does this. I did not feel safe as well as many people I've talked to and this has happened to them. It is a known issue on the e92 BMW around 79,000 miles. The BMW M3 of this year is very popular and there are many owners. The rod bearings also go out in this car and create the same safety issue. I believe the throttle actuators and rod bearings going bad and putting the car into limp mode is an incredibly dangerous issue. I have called BMW na and they will not look into them as they are not an 'active recall'.
