Is the X5 still plagued with quality problems?

[btrvalik]

I just bought a 2005 3.0i and will be picking it up tomorrow. I knew that it had some issued with earlier models but I thought they've gotten things ironed out. After telling this to a couple of friends I've been hearing X5 horror stories. A friend with a 2000 has had nothing but trouble.. repeated power window problems, check engine lights, and now a new trans.. for something like $5K. He said that he is glad he got the extended warranty but would never buy another. Another friend told be that when his got towed the driver said "I pick up these X5s constantly". I also got some 3rd party story of someone having to have all the chips re-flashed.. seems a little far fetched. On contrast two friends with 2003 and 2004 have had no problems. Have they got these problems nailed yet or is it still a problem?

Thanks
