What owners wrote

“12 Volt battery dies frequently leading to the vehicle becoming inoperable. Subaru has so far provided little information regarding a permanent fix other than to discontinue all use of mobile apps that connect to the vehicle and to move any key fobs away from the vehicle as far as possible. The issue occurs on average one a month from my experience, and requires the car to get towed back into service.”
