“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.”

If there was cars next to me there would have been a crash. Since then Bmw has issued a customer campaign on the n63 engine effecting thoughts of cars. They are changing tons of parts from injectors to fuel rails. It should be a full blown recall and the NHTSA should get involved on this. My car has been in the shop since 12/23 and still has not been repaired correctly. …”

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. …”
