So I drove my car to the airport and left it there for a week and you are telling me the battery will just drain over the week? I mean I get that there are a lot more electronincs in the car but that is insane. I was able to drive it when I returned on Wednesday and used it Friday and Saturday as well. I guess not using it yesterday finally drained it. I completely regret this car if this is going to be a recurring problem. I get sent on business trips often and park the car at the airport a lot and I live in a condo setting and do not exactly have a lot of storage space to keep a battery charger.
