NHTSA Complaint #11436707 — 2020 SUBARU LEGACY

We were gone for 10 days. Our Legacy was left under carport (North end of garage/shop). Upon our return, we found the battery was drained. We have only 7362 miles on it. I bought it new in June 2020. We tried to charge the battery, but the charger stopped charging and the red "trouble" light came on. We had to have the car towed to the dealer in another city. They mentioned that we need to drive car often and not leave it sit or this will happen. Luckily, there was no "trouble" only a drained battery, but it was an inconvenience. We bought the car based on Subaru's reputation for durability. We are 78 & 83 years of age respectively and my husband and I have medical issues. We need a car we can rely on at all times in case of an emergency. If this is a known problem, why was I not informed of this upon purchase? Why was there no mention in the owner's manual or new owners handout. Since the incident, I see many complaints on Web.
