I have the same problem with my brand new Forester Hybrid. Bought at the end of February 2020, the problems with flat battery started almost immediately. My mileage is low at best of times but just now with lockdown, even lower. Had 2 failed attempts to start. Dealer has said that if it continues he would fit a bigger battery but he did say that after the first occassion. He also suggested that I dont lock the car as the alarm takes power from the battery. Guess my insurance would love me doing that! Only 500 miles and getting disappointed.
