2007 BMW X5 SUV 4.8i 4dr SUV AWD (4.8L 8cyl 6A)
Poor Reliability
 Lots of power, great handling and lots of quality issues. In less than 36 months it has been in the shop a good 1.5 months. Two dead batteries caused by flawed electronics, non working air among other things. Completely dead twice so not a trust worthy car for a trip. Also issues take a long time to run down issues so it is out of service for a week or two at a time. This SUV is made in SC and not Germany and is far from reliable. When it dies it dies as everything is electronic. You need a special tool even to get it into neutral.
