2007 BMW X5 SUV 4.8i 4dr SUV AWD (4.8L 8cyl 6A)
Got out just in time.
 Our X5 was bought new in February 2007 and regularly maintained thereafter.  It was our fourth Bimmer and, probably, our last.  The car was comfortable, had good performance, and good looks.  The I-drive was OK and there were enough knobs and buttons to help you avoid using it.  Panoramic sunroof was great, wished we'd used it more often.  The first several years were uneventful, just what you want in a car.  The last few, however, were anything but.  We got to the point where we were afraid to take it out for more than 100 miles.  We spent $3,400 getting a "valley" gasket fixed.  That was the beginning, leaks began showing underneath the car.  Not only oil but brake fluid, power steering fluid, etc.  Our local, well-regarded BMW specialist said to get it steam cleaned top and bottom so they could assess where the leaks were coming from.  I read horror stories from other owners about mid four figure repair costs for leaks, one guy spent $8,000!  After the steam cleaning our mechanic wouldn't return my phone calls, I think he knew he could only give me very bad news if they put it up on their lift.  The steam cleaner said not to drive the car very far after the cleaning because the leaks looked to be numerous.  With great relief we traded it in on a new Acura RDX last week after having driven it 98,000 miles.  The guys who write the BMW commercials should build the cars because BMW reliability is a thing of the past.
