In November 2016 I bought a new 2017 Outback. In the summer of 2018 I left the tailgate for about 4 hours while I was unloading bags of mulch, etc. I made sure that all passenger doors were closed, and all the interior lights were switched to off, so they wouldn't drain the battery. Outcome: dead battery when I tried to start the car 4 hours later. I jumped it off, took it the the dealer that day, they could not diagnose the problem. I found a blog on the internet that suggested simply having the tailgate open somehow drained the battery because sensors were constantly sending signals to the motherboard. Then an unrelated thing happened in 2019 when I had to park on a narrow residential street to attend a short meeting - I turned on the hazard flashers and 45 minutes later when I returned to my car - you guessed it - a dead battery. That doesn't speak well of Subaru safety if you break down on the highway and have to wait 2 hours for a tow truck, your emergency flashers could give out before the tow arrives!
