fuel pump was replaced under warranty; however, the failure recently returned a third time. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 87,000.
Nothing has failed yet, however, the oil stick is completely illegible. On a car that fails to have an electronic dipstick and likes to burn oil, as well as has a very small oil capacity (Around 5 liters or less) this design is going to cause the engine to run out of oil without the driver knowing. It is a seriously bad design, especially combined with BMW recommending a 10,000 mile oil change, the car will burn off all the oil it has and operator will have no idea due to the faulty design of the dipstick.

generally like BMWS engineering and designs, but this one is just atrocious and I have no idea how it got approved. Running a car out of oil usually causes the engine seize unless you shut it off at the right time, which, most people will not do. Imagine if your engine seizes on the highway? No it hasn't been inspected, I can send pictures of it, if you want? Or a video? I have not had this problem yet (knock on wood) but I have read the only warning sign, is the sound of an engine without oil and the oil pressure light comes on (which at that point you have maybe 3s to pull over and shut off the engine before it toasts the engine) I have also read about the engines consuming the entire oil capacity if you follow the BMW recommended schedule. It all just seems like a huge oversight for a company that usually has few issues.
The car stalled while driving on freeway once and high pressure fuel pump was replaced by mini cooper and again second time on inner roads driving at 20 miles an hour....Without any warning
Engine rattling noise (timing chain and tensioner) at all times, vehicle has only 50,000 miles
