The contact owns a 2010 BMW 335. While driving at 5 mph, the brake pedal was depressed and the vehicle accelerated independently. As a result, the vehicle crashed into a pole and a building. The air bags failed to deploy. The contact did not sustain any injuries. The vehicle was taken to an independent mechanic who diagnosed that the dde and dtc modules needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 30,000. Updated 7/7/15

I was driving on the highway 295 around 67 mph. While I was on the highway about 10 minutes I felt a loss of speed about five times. It feel like I let go the gas pedal, but I never did. And suddenly the car stalled while I was on 67 mph. I try to pulled to the right side lane of the highway. I try to start the car back up but it won't start. I keep tryin for about ten times and it about half an hour went by it start back up again.

This 335D had a history of engine light-on events prior to potential catastrophic uncommented engine runaway. On Jan 13, 2013 customer was driving vehicle at cruise control at speed setting 83 mph on turnpike at 11pm. Suddenly engine light came on, followed by a significant reduction in engine power output. Engine was unable to handle power requirement to keep cruise control speed at 83 and vehicle's speed dropped to low 70-ies mph. ECU did not disengage cruise control while engine power was reduced. Suddenly vehicle accelerated uncommented back to the set cruise control speed of 83 mph. Very dangerous and scary situation. Vehicle was brought to BMW service on Jan 16 2013 and remained there for over 2.5 months! many parts were replaced and engine light-on event was replicated several times by service mechanics. BMW center manager stated "we do not want to sell your car to any of our customer, they may have the same problems you had". ironically, vehicle was returned to customer on March 27, after 70 days of repairs and troubleshooting. Customer was shown pictures by service manager of cylinder head, one of the many parts that was replaced, that was full of gunk and carbon build up. Cylinder head was then apparently mailed to BMW germany for further analysis. BMW service manager stated that this vehicle was probably not the only vehicle with this problem.... no root cause was ever provided about vehicle's engine light, significant carbon build up in cylinder head and safety issues.

I was exiting a freeway and was attempting to pass a slow moving vehicle in front of me. I passed the vehicle and accelerated in order to keep a safe distance between me and the car behind me. Much to my surprise, when I "put the pedal to the metal", I experienced a loss of power. My car completely lost power for about 5 - 8 seconds. The car I had just passed nearly rear-ended me because they did not expect me pass and then reduce my speed. I took my care to the BMW dealer who claimed to have never heard of such a thing. They checks out the car (it was approximately 3 months old) and could not duplicate the problem, I was told to drive more often in sport mode. This has happened two other times over the last 21 months and the dealer has said each time they could not duplicate the problem.

I have a 2010 BMW 328I. The brake pedal and the gas pedal are too close together. When engaging the brake, my foot comes in contact with the accelerator and I am afraid that this may lead to an accident. I took the vehicle in for service and the dealership said there was nothing they could do. I have had other BMW's and have not had this issue. I also have a 2009 escalade and this is not an issue on this vehicle.
