I have a 2006 400h, and I love it except for one thing: the battery (the small one that powers the electronics and stuff) keeps discharging. :o
The first time, about 3 months after getting it, it died after I left the radio on for about 10 minutes. When I came back, it wouldn't start and nothing lit up. I left it for a few hours, and it came back enough to start it. I drove around for a while and it was good for a few months.
Later, it started dying spontaneously, even when I hadn't left anything on. I would come back in the morning and it wouldn't start. Once, I left it and it came back, another time I had to jump it from my wife's car (a MB...), another time from our jet ski (don't ask, it worked).
Finally, I got fed up with it, took it in, and they replaced the battery. It was good for about a year, but now it has begun to die randomly about once a week for the past few months.
Has anybody else experienced their battery dying spontaneously?
EDIT: Looked around on here a bit, and saw a few others with this problem. The funny thing about my car is that I never have to reset the windows or anything like that.
