So our 2020 Ascent battery is
So our 2020 Ascent battery is dead. It is over 1000 miles and we (for the first time) opened the rear hatch for getting out and putting in Christmas presents. It happened over night so this issue continues. I too want to know if I get a more powerful battery, does it void the warranty and extended warranty that I have purchased? I get that I can go to to Subaru and get another OEM battery but if it only lasts for less than a year as well, why would I want to?
