4 key turns. Thx SGB!

I have to replace almost EVERY Subaru OE battery on the 2016-2018 Legs/OBs I buy. Some of course are already replaced. To hear that a one year old has a bad cell has me shaking my head. The Interstate depot is near me north of Boston, and where I used to source their durable batteries wholesale. Now that COSTCO sells Interstates for even less than dealer wholesale is a gift to us all. Either the 25 (OE 550cca size $80) or the better and longer 34 (800 cca, $85) work superbly. Yet parasitic losses in Subies are on the high side, so ANY battery will soften if the vehicle's not driven for several weeks...especially in deep winter. Your choice of a new 2020 Legacy 2.5i Premium is one I condone, as the low CoG tames the body roll and sloppiness far better than the too-tall Outback. It's too bad there are no parts available (yet) to remedy the newest OBs. ANY first year production has teething pains, but since I don't see the newest crop in repair circles you perhaps would be best to befriend an ace wrench or service manager at a Subie dealer to find out the skinny on myriad new-car foibles. I've wondered if a 2020+ Leg 2.4t might someday be my personal swan-song pet, but Toyoburu hasn't mated the turbo with the CVT well enough yet to be that satisfying. Your 2.5i was probably the wiser choice. I don't know if they beefed up the weak wheel bearings, but I suspect you'll come to like your Legacy more over time. Keep tire pressures on the hard side for better control in the twisties, and don't think that going to 18" wheels with 50 series tires will help with handling much, as there's simply a too soft suspension setup. But it IS comfy, eh?! Good luck. Ern TSG/B

Just lost a LONG response before capture. Crap.... Summary: all OE SOA batteries are bad. To lose a one-year old is unusual, but not rare. I've used Interstates for decades partly because of a local wholesale depot, so was thrilled to see that COSTCO picked them up for even lower prices. The 25 (550cca, $80) is OE sized, but the better and a bit longer size 34 (800cca, $85) is the real deep winter winner. Despite first year teething pains that only dealer service managers and top wrenches will have data about your 2.5i Premium is a solid choice. I wish the too-soft suspension would be stiffer to complement the sedan's lower CoG, but it's aimed for comfort and not spirited handling, and there are no remedial parts available (yet). The 2.5iCVT combo is well-honed, durable, and efficient. I don't know if the same undersized soft wheel bearings continued into the 2020 iteration; you'll know in a few of years, but that's low- cost stuff. Don't bother to consider an "upgrade" to 18" wheels ala the turbo or Limited, as the suspension is too soft (for comfort) to take advantage of stiffer tire/wheel setups. The 225/55R17 is a nice all-season setup (as used in older, lower chassis OBs in the noughts). I recommend you swap to 5w30 synth (international spec for all Subies) instead of the piss-like 0w20, which most Subaru wrenches laugh at but are forced to use. Keep tire pressures up at 36F/33R for better road feel, and keep from having 3 passengers in the rear or bags of pond stones out of the trunk to mitigate body control. Ha! Good luck, and keep safe.
