Three problems related to other fuel system pump have been reported for the 2012 BMW 550. The most recently reported issues are listed below.
The high pressure fuel pump caused a fire in the engine compartment and totaled the car with less than 60k miles on it.
Fuel pump disengages when the car gets too hot. It's happened three times fortunately each time I was going 20 mph or less. The car essentially stalls out and at higher speeds could be an issue. BMW has made a fuel pump recall but the 2012 550i did not qualify and I believe it should.
I have a 2012 BMW 550i, crosstrack, v-8, and with only 5500 miles (purchased in July 2012). When initially starting my car on a flat plain, the behavior of the car started to shake fiercely, repeated loss of power, and the I-drive reported the chassis was malfunctioning. Only moderate driving was permitted. The engine light stayed on, and no matter how far the gas pedal was pressed, the car would not gain power. While driving, the car stalled several times as I was attempting to go up the hill to my home. When the car stalled, the gears would not go into neutral or park, and the steering wheel locked up immediately. This experienced was close call to crashing the car and possible sustaining significant injuries. After waiting for three hours, the car started up normally. Several people who have chatted with regarding the 2012 BMW 550i crosstrack, v-8 have reported these same experiences. Apparently the reports all link back to the fuel system. (e. G. , fuel injectors, fuel pump, fuel sensors, etc. ).
