One problem related to clutch has been reported for the 2009 BMW M3. The most recently reported issues are listed below.
In the 2009 BMW M3 sedan with dct (dual clutch) transmission, there is a significant lag or hesitation of at least 1 second between applying pressure to the accelerator and the clutch engaging and giving acceleration to the wheels. This does not happen from a stand-still, but occurs primarily when the car is in motion at virtually all ranges of speed, from rolling stop (5km/hr or less) through standard road speeds of any degree (residential 30-40km/hr, city roads 50-70km/hr, or highway 90km/hr+). I was carefully in the middle of a slow left turn at an intersection on Saturday, Feb 7, 2009. To avoid an oncoming car prematurely heading in my direction, I pressed on the accelerator to hasten the completion of my turn, but the car did not respond because of the clutch lag. I narrowly avoided being hit. This transmission defect could reasonably result in serious injury or death to the driver or passengers, especially when sudden and unanticipated acceleration out of a difficult driving situation is required. The consumer stated he also experienced unexpected stalls during low speed driving, but not rapid deceleration. Updated 03/11/09.
