Other Fuel System Pump problems of the 2011 BMW 750

BMW 2011 has only 88,000 miles and both high pressure fuel pumps need to be replaced at a cost of $1400. The car was in motion and said powertrain malfunction, the car slows down on the road which can cause an accident, starts jerking and spitting white smoke. This is a know problem under sib130215 which states only production dates between Jan 2011 and Dec 2011. My production date was oct 2010. The same problem exists with many of the n63 engine cars. Please take a look at this problem as it seems to be a defect in the engineering of the vehicleand not necessarily the parts. This causes a serious problem when driving on the highway. Also, I had to get all my coils and spark plugs changed as well which was not covered in my warranty. This is also a known problem for these cars. The customer pays too much for these cars to have a totally defective vehicle.
