One problem related to other fuel system pump has been reported for the 2011 BMW 7 Series. The most recently reported issues are listed below.
Since I bought this car in 2012, after warranty the car has constant breakdowns, I have spent >3500 dollars in last year, again got a message "drive train malfunction" about a week ago, took to dealer roadshow BMW in memphis, they said high fuel pump and plugs need to be replaced in about $1000, I agreed and left car, two days later they called that there is another 'plate leaking oil' and needs another $1000 repair. This was not there when I left the care. I called BMW customer service first time, about 6 months ago, with out help, and again yesterday. My car is in shop at dealer. I came to know that this fuel pump problem is very commonly reported in BMW but surprisingly company has not recalled it or accepting responsibility. This is a dangerous situation that could result in fatal accidents and injuries. BMW should be held responsible for repairs and recalls and fixing these problems before fatal injuries occur.
