NHTSA Complaint #11422068 — 2020 SUBARU OUTBACK

After leaving this car in an airport parking lot for 4 weeks, it would not start. I also noticed that all of the doors except the hatchback were unlocked. I coincidentally had a jumper battery unit in the car and was able to start it with the external battery jumper. When I drove the car the 30 minutes to my home, I found that the battery had not charged at all. This meant that until Subaru fixed this on warranty, I could drive the car but would have to raise the hood, hook up the external jumper unit, start the car, disconnect the jumpers, close the hood and finally drive where I was going. This procedure grows old after doing it repeatedly to shop for supplies after being away for 4 weeks. The Subaru dealer fit me in the following day and confirmed the battery had been destroyed by the car sitting unused for 4 weeks. He recommended that I always leave a small charger on it whenever it will not be used for 2 weeks or more! That would have been impossible at the airport parking lot. I have taken this car on very many severe backcountry drives where failure to start when it's time to leave could be problematic or even fatal. Whatever is the problem should be fixed. If the new battery will fail the same way, it should be replaced with a battery that won't, on warranty. If it's the charging system that's at fault, then the faulty design should be corrected.
