I've had a few issues with my 2012 Hatch WRX and the battery. when I have to go out of town for more than 3 weeks (happens often since I'm in the military) my battery will be dead when I get back. I jump it and drive it around for a while and its fine till I go out of town again. I had my car in for maintenance at Subaru and asked about it. They said that's a common problem with the WRX because of all the "functions with the ECU that are always on". The dealer checked the battery for dead cells and said its fine. They suggested I get a battery maintainer/flow charger to keep it charged when I go out of town. I asked a few friends with WRXs and STIs and they seem to have no issue. So I bring it to you Club WRX. Is this really a common problem or is the dealer feeding me BS?
