2011 BMW X5 xDrive50i 4dr SUV AWD (4.4L 8cyl Turbo 8A)
As with a prior review, my 2011 X5 5.0 also makes a whinny noise akin to a golf cart when engine is hot and when upshifting from 1st to 3rd gears. Getting worse as mileage adds up. 2x to the dealership and nothing can be done as it is the alternator? Give me my 2007 4.8 back please. Heard the 2011 7 series is also having this problem. Not acceptable for 75k cars
