More electrical gremlins.......

So, after work last Friday, I got in the car, and it initially doesn't start: i.e. the engine doesn't turn over, no clicks, NOTHING. So I tried once more, and the car started. However, the automatic transmission light, brake light and 4x4 light came on, and stayed on for the duration of my drive home. In addition, during the drive home, shifting was extremely erratic, and braking was a bit scary, as the brakes would grab again (and rather intensely, I night add), after I'd released the pedal. Anyway, I got home safely, a little frazzled, but safe, nonetheless.

I took the car in to the dealership on Monday, and got a loaner (another '06 X3). The dealer states that they found a number of fault codes stored by the computer, but that they were unsure of what the codes meant., so they: "opened up a PUMA technical." Whatever that means. They reprogrammed the computer, and now my car's behaving as it did when I first brought it home almost a year and a half ago, and is running perfectly.

Has anyone had a similar problem? I'm a little apprehensive that this just might happen again, and the next time my driving experience won't have a happy ending, especially with the braking issue. I'm also wondering if this has anything to do with the fact that my battery died several weeks ago when the car was left at the local airport for 4 days. The dealership refused to replace the battery, but recharged it, and I'd had no problems until last Friday.

Thoughts? Comments? Ideas?
