2010 BMW 5 Series 535i xDrive 4dr Sedan AWD (3.0L 6cyl Turbo 6M)
This is my third BMW. The car handles as expected and offers the joy and experience BMW owners have come to expect. However, the reliability on this vehicle is unacceptable. First, I had a fuel pump failure. I noticed several slow starts, took it in and they found a fault with the fuel pump. Next, I was accelerating hard when the engine lost power and the message "Engine Malfunction: Reduced Power" displayed. So far, the dealer things it's a software issue. I love these cars, but reliability is sub-par. If BMW doesn't resolve their reliability issues, I purchased my last one.
Acceleration and handling; solid feel and even the iDrive.
Reliability of electrical system and associated computer systems; nav could be more intuitive, though it's tolerable.
