Subaru Legacy factory battery failure at 16,400 miles replaced with new battery on Subaru Legacy

Some Subaru Legacy owners report experiencing factory battery failures, even at low mileage, with some batteries appearing completely dead shortly after purchase. In response to these issues, dealerships have acknowledged the problem and replaced affected batteries with larger upgraded versions. Additionally, owners are advised to use a battery pack to jump-start their vehicles if necessary and to have the battery tested at the dealership to assess the need for replacement. Subaru has been known to replace batteries under warranty, and certain models may come with extended battery warranties. Furthermore, if a Legacy's battery is losing charge quickly despite recharging, it may indicate the need for a replacement after ruling out other issues like a faulty alternator.
