I have a 2025 Yukon AT4 that the battery is dying on once or two a day. Battery, alternator, and starter all tested fine, but we have to jump the vehicle after it's been sitting for more than 4-5 hours. There are no chargers or aftermarket accessories plugged into it. Something is clearing drawing power while the vehicle is off. Never had this problem before. This seems to have only started after the most recent OTA software update, which was installed mid-week last week. Anybody else having this issue? Any suggestions? Thanks in advance!
