After a trip, I was supprised to find my battery was dead, only 10 days. I jumped started the car and took it to the dealer. The car is only 9 months old. They worked on it for 7 days and said it was fixed. One week later and after only 2 days of no activity, the same problem, dead battery. I understand this can be a problem after 30 or so days, but of course should not be the case after such a short time. Any help would be appreciated.
