That doesn't seem right- I just took a look at a 13 Legacy Outback wagon, and the battery in that one is rated at 490 CCA (which I think is low for a cold area like I am in, most are a minimum 0f 600 CCA) if 356 is what the battery is reaching when it is being tested, it is definitely low. I would contact the dealer, and if they don't give you satisfaction on this, then ask the service manager for the number for Subaru's Customer Care line. That ought to motivate him, everything is all about Customer Satisfaction scores in the dealerships.
