BMW 650 N63 engine issues aka drivetrain malfunction (dtm) error has been a very common issue in these cars. If you do your research people with brand new cars with less than 100 miles have these issues as well. Long story short BMW, na offered to buy back my car after spending more than 5 weeks in the shop for 2nd repair. First repair was the recall, BMW offered as the "customer care package". I purchased it cpo (certified pre-owned) w/ 26,000 miles., I was unhappy with the offer since they deducted mileage used. Dtm occurred at approximately 29,000 miles after having the car for less than 4 months. Of course the BMW dismissed it since the dtm resolved after restarting the car. It usually occurs randomly while driving high speeds above 60 mph on the freeway the car shakes, rattles, decelerates and is unresponsive when stepping on the gas. This is a known issue in new 650I w/ N63 engines please check youtube, BMW forums and class action lawsuits filed 9/2015 agains BMW, na. The vehicle was getting all the parts replace for the entire month. The car was fine for 2 months than it occurred again and since they did not want to extend my warranty I decided to request a buy back. Other issues: Excessive engine oil burning, back passenger windows not rolling up completely rear wheal cracking. Dtm still occurred after these parts were replaced in the car for the 2nd repair: -catalytic convertor (since they discovered both catalytic converters where coming apart), all 8 spark plugs, 32 valve guide seals. I hope this was of use for someone who feels helpless and have to settle whatever BMW, na is offering. Still entertaining the thought of filing a separate claim from the "buy back" offered by BMW. This is a huge safety issue which may lead to a fatality due sudden deceleration when driving in high speeds.
