Battery drains over night

[oubbascooba]

I used to work at a Ford dealership. Customer had same problem & techs couldn't figure out out. Ford sent in big wheels. They couldn't figure it out, either. He was getting irate with the store & Ford. I sat with him & had a conversation. Asked him a bunch of questions. Figured out his key fob was bad & was constantly sending signals to the truck drawing low power. He drove the truck Monday thru Friday for work & it was fine. But every Monday morning, it was dead. Check your key fobs. Try leaving your Jeep somewhere else overnight away from the keys. That should tell you if that's the problem.

holy crap, i traded a 2014 F150 due to overnight drains and they couldn't locate the problem. No other issues over 6 years. If it was as simple as that for my truck, i would be pissed. But its been since 2019 since i traded it haha. I want to say i started using fob 2 because fob 1 battery was dying, but fob 1 was always within 20-30 feet of the truck every night. Makes me wonder now.

I left the dealership around 2019 or so. His truck was probably a 2018 or 2019. He told me he drove it to New Orleans airport to catch a flight for a week. When he came back he said it started fine. So that got me to thinking it had to be something at his house. It would start up fine after one night. But he would park it on Friday afternoons & not drive it again until Monday mornings & it was always dead. So, apparently, it was a very small signal it was sending.

Our 2022 3.6L with etorque needed a new 12v battery in February or March of this year. Replaced it and it was fine for 6 months and then we started having a similar issue. Tried load testing and it was fine. Showed similar low draw like yours when tested. Sometimes it would make it several days, sometimes only 1. Tried disconnecting the winch. No fix. Tried unmarrying the tazer. Problem persisted. Finally said screw it and threw a new battery on it... and it's been fine for 3-4 months since. Being that the dealer will charge you the same cost of a new battery for troubleshooting and confining the etorque is charging properly and that is the 12v battery I'd start there even though the etorque system is covered by an 8 year/80k mile warranty.
