I have a 2007 X5 that I bought CPO in 2008. It is a beautiful black sapphire car that is fully loaded.......It came with every option available including comfort seats on a sport model. The car drives great.....when it works and I have full warranty (both types) until November 2012.

The problem is that the damn thing keeps breaking. There is something wrong with the electrical system and it has been in the dealership a dozen times for these gremlins. It has broken down on the side of the road two times (and the number would be higher but for the fact I am now keen on the warning signs) The alternator, battery, comfort access system and just about every thing possible has been looked at or replaced. I've been told that I need to trickle charge the battery every few weeks (which I do). While the dealership is nice and responsive it has gotten to the point of absurd.

I know the easy answer is sell the car, but when I buy my cars I like to keep them. I just feel like I'm getting screwed because BMW can't fix/find the root issue.

Other than sell the damn thing and never buy another BWM (my other car is a 330) does anyone have any ideas? It just is not right.
