Good to know that Smart has a fix for the '09 Smart. I had a similar experience with my '08 coupe, so the problem may affect more than the '09 cars. A couple of weeks ago, I went to start the little one after 8 days non-use and found that my battery was dead. I had left the headlights and wipers set to automatic (as I generally do), so this may have been the cause of the dead battery. I now turn the auto features off when the car will be parked for more that a couple of days. I plan to check with my dealer to find out whether the '08s are included in the fix.
