NHTSA Complaint #11439800 — 2015 SUBARU OUTBACK

My 2015 Subaru Outback has continually experienced random battery drain. I have replaced the battery 3 times since purchasing the car from a dealership in 2017. In all cases, there was no advanced warning indicating that the battery was low, the car had been driven regularly with an average amount of mileage and no lights were left on nor was there extreme weather. Most recently (11/7/2021) the tailgate was up with the car off for 30-45 minutes. It was jump started, we made it home and the next morning it had zero power. That last battery was purchased in April of 2021. The car is regularly maintained by the dealer and/or a certified mechanic.
