The car has displayed "drivetrain malfunction, drive moderately" twice now in less than one year of ownership. When this display has occurred, the car goes into "limp mode" and can only be driven at low speeds or with very sluggish acceleration. This is a safety hazard, as it becomes easy to be rear-ended by another driver when it slows substantially.

I had a powertrain malfunction light come up the first weekend after I leased the car, with barely 250 miles on the odometer! repairs were done at a BMW authorized service center, the car now has 6000 miles, and the issue is back! this is the 2nd time within the last 6 months this car has had powertrain warnings pop up. Its christmas day, and I have a brand new car (barely 6months old that is), yet I cannot drive it. There should be no reason for a brand new luxury car to breakdown twice for the same reasons within 6 months. I got lucky the car did not shutdown on me and I was close to home so I could limp back home and have it towed. I have heard of others having the same issue and their car shutting down in the middle of the freeway. BMW is selling a sub standard, untested product, that is potentially unsafe. This needs to be investigated.

Transmission problem resulting in violent shuddering of the vehicle body and abrupt engine stops resulting in dangerous driving conditions. Fluctuations in the tachometer when the car attempted to stop and the car would automatically change gears to neutral or park.

I started the car and reversed out of my driveway, then proceeded to a very busy intersection without stop light. I accelerated to merge withf traffic and all of the sudden my power was cut dramatically and the car displayed a drive train malfunction error. This prevented me from accelerating at the correct speed and almost created an issue with the vehicles behind me. I then had to pick my child up school and the car continues to behave poorly.
