NHTSA Complaint #11477624 — 2011 BMW 550I

I started my car to drive to an appointment and noticed that the car was jerking/bucking as I pulled out of my driveway onto the main road. I was unable to accelerate appropriately for oncoming traffic behind me because the car was jerking violently and it was a bit scary since this had not happened before. This continued for several days, primarily when I would attempt to drive the car in the morning. On one occasion the drive train malfunction light illuminated as I was making my way to an appointment at the Veterans Administration and I had to gingerly turn the car around and head back home. Someone could have ran into me because the car didn't have much power. What followed next was the inability to get my car to move when it was placed in reverse. I took the car to the dealership and was told that the car's transmission needs to be replaced ($11,000) because the car is trying to drive in reverse and first gear at the same time. What?!! In over 20 years of servicing BMW's, they have never seen a situation like this. I don't believe I should bear the cost for this when I bought a pretty expensive car in good faith, which has only 80,000 miles.
