I purchased this vehicle thinking that it would be a safe car for my family and friends. The transmission seems to be slipping and an excessively harsh 2-1 downshift occurs when decelerating to a stop. Also, transmission "bangs" into gear when accelerating from a full or a "rolling" stop. This occurred several times on a daily basis. One time in specific I was driving with my 4 year old niece and it caused her to become alarmed as well as injure her neck. Please let me know what can be done, the dealership is saying that they will charge me an ridiculous amount of money to upgrade the software for the transmission. I strongly feel that this should be a "no charge" repair or fix seeing that no car should behave in this manner. Please let me know what can be done, as I am no longer driving the car and taking the bus in fear of causing any injury to my loved ones.

Transmission jerks and slips. When coming to a stop, the car slams into gear. This could cause a major accident if this occurred during wet or icy road conditions due to breaking traction from wheels and road surface. This is a major concern and after doing some research, thousands of 5 series BMW's have this problem. The result is a defective mechatronics which costs between $5000-$8000 to fix and not covered by BMW or under warranty.
