Starter problems of the 2015 Subaru Forester

I have a 2015 Subaru Forester (less than 32k miles) and my car has not started on 3 different occasions this last year. This last time I was with a friend and we parked on a somewhat darker city street late at night where I turned off the engine to not waste gas and talk. The only thing I remember doing was turning on the upper car light for 60 seconds to find my friend's phone and adjusting the driver window with key in accessory mode I believe (engine was not running). We did not use the radio because embarrassingly, the same friend had waited with me the time before when I played my radio for 10 minutes one time. So again, my car didn't start, and she had to wait with me once again 30-45 minutes until help came to give the battery a jump. It seems to happen either when I sit in the car with the key out and use the internal light (even for only 60 seconds like this last time) or if keys are in, listen to the radio for a few minutes only without engine running. Anything turned on after the car has stopped running seems to mess with the battery and I'm afraid it won't start. This last time when it wouldn't start the engine, I noticed that my drivers window did not roll up (even though the other windows did) and then it started to grind when I tried to start it multiple times, waiting a little time in between before trying to start it . . . Then it seems to slowly drain until no lights at all in car. The tow company tested the battery and said it is still good, there was no problem with it, but mentioned maybe it's not getting both cells to charge equally or has something to do with starter, not sure. When I first bought my car, I remember dealership mentioning the electrical and not holding them responsible (?) I think if they knew about this, they need to recall and fix, or give us a portable car jumper. Sad because I love my SUV otherwise. :(.

I had a remote starter installed by some one other than Subaru. The starter failed repeatedly so I took it in. Was told and given a print out reflecting a low battery. I took it to north towne Subaru on sheridan dr. It is a 20 mile trip one way, they said "no problem, charged the battery any way and sent me home. I purchased the Forester in sept. 2014, got the starter for christmas,and after the visit to Subaru it worked sometimes. This winter again it failed to start. Now that the winter has become extremely cold I returned to the installer who replaced it and it still failed due to a low battery. This, as I understand it, is a continuing problem with this model, and the fix is a stronger battery. I am not about to take another trip to Subaru in erie CO. As I am in pain most of the time and driving long distances increases the problem. I told the starter store to order me a battery to fix the problem as I can't see Subaru in amherst doing anything for me. But I do think Subaru should reimburse me. Of course I will not hold my breath. Also I will never go to that dealership again. !!!!!!.
