I have a newer 2020 Lexus RX450H - Twice now, I have found it with a dead battery after traveling for 7 - 14 days and leaving it parked while out of town. Seems ridiculous to have to ask someone to come drive my car while I am out of town. Thus far dealership has said there is nothing wrong with the battery. this seems like a design flaw to me. I am a low mileage driver (i.e. less than 5K miles per year).
