2025 Tahoe ParasiTic draw

[Msgt Mailman]

I bought a new 2025 Tahoe RST in January. It has around 2k miles. Since January i have had to jump start it three times. First two times was after being on vacation and it sitting. The other night i drove it for a short drive, went back out less than 12 hours later and had to jump start it again. Took it to dealership and they said all they checked was the battery, starter and alternator. They said all three were strong. They are gonna leave it overnight and check tomorrow and if it doesnt start they will just change the battery. Has anybody had similar issues? Very frustrating!

I've had to jump start my 2022 Yukon Denali on average every two weeks or so since I bought it over a year ago. I drive it regularly and when I don't, it'll barely last 5-6 days. I'm out of warranty so I get to pay for the software updates that don't fix the problem. I have zero confidence in the truck and it's embarrassing. Judging by the Carfax and service history, this has been going on prior to me owning it, but now it's my problem. Of course, the dealer can't find anything wrong.

Original battery?

Battery was replaced last year. And it tests good.

Loook under dash… above OBD port… u have a low jack or some other device connected. Turn off approach features (lighting, locks) and the lift gate. Store your key 21’ from vehicle.

In addition to the above responses... short drives don't fully charge a battery. Use a maintainer or take it for longer drives.
