I was trapped inside my vehicle when the battery died. While sitting in my car using the accessories to charge my phone, the car battery died and I was unable to unlock the doors to get out. The key fob did not work either. There is no inside handle on the rear hatch. The dashboard lights flickered a couple times and after about three minutes the door did unlock. What if the battery was completely dead? what if I did not have access to a cell phone and it was cold temperatures? I do not think I would be strong enough to kick out the windows. I am concerned and hope you will investigate. Thank you.
This is not exactly a safety problem, but could be a critical issue. We left the brand new Subaru 1015 Forester for two weeks while we were on vacation. When we came back the battery was dead. Aaa tech told us this is not an uncommon problem in 2015 cars with full complement of features, and typing "Subaru battery drainage problem" into google brings up a litany of complaints. Apparently all the electronics in the car drain the battery even when the car isn't running. Subaru implied it was our fault for not starting the car. That's absurd. We have a 2010 Honda civic that was under the snow for 6 wks. And it started right up. Subaru checked our battery, pronounced it healthy, suggested we buy a trickle charger (which we have done), and sent us $100 for our loyalty. Nowhere in the Subaru literature does it say that the car must be started every few days or warn about battery drainage. If we'd had an emergency that required us to use the car when we first got home, we'd have been pout of luck. This technology is not ready for prime time, and at the very least consumers should be warned.
