NHTSA Complaint #11486291 — 2017 SUBARU OUTBACK

Our car battery does not hold a charge. One year ago January we had Triple AAA replace the battery after several problems starting. This year we have had 3 calls to Triple AAA to charge the battery. It starts right up when they apply the charger--alternator tests as working properly, battery tests OK once charged--but the problem keeps happening. I am now afraid to take it anywhere where I might be stranded. Got a card about a class action lawsuit against Subaru regarding battery drainage issues. I mentioned this to the Triple A tech who mused, "You know, I have had a lot of dead battery calls in the last year for Subarus." Since AAA changed that battery a year and a half ago, he said if it happens again, they will replace the battery because it is under their warranty. The Subaru dealership has not sent us a recall notice. It seems they are not accepting responsibility for this defect. What is an owner to do?
