My 2007 X5 has been nothing but a nightmare and the worse vehicle I have ever owned. I've owned many new BMWs (3, 5, and two 7 series) but my X5 is a completely different experience. It is a loser, a huge disappointment in terms of quality control, problems, but the worse part is how BMW has handled the issue - which is VERY poorly. X5 was in for recurring service issues 2+ months in 1st 2 years for a series of false engine warning lights, Ele issues, rear hatch door problems, and cosmoline that drips onto glass/paint. No support from BMW. Had to retain attorney as BMW NA could care less. BMW NA Execs clearly more concerned with their stock options than long term customers. Bye bye BMW!
