battery won't hold charge
3 Answers
It could be a bad ACM (Audio Control Unit) The ACM may need a firmware upgrade also the original Mexican 12 volt battery was defective on some models. If the battery is more than 3 years old it could just be normal wear a tear and needs replacement. I would charge the battery full overnight then do a load test (AutoZone can do that) to determine if the battery is still good or not as a start to fixing your issue. I have a 2017 Fusion Energi Hybrid with the same problem, it's at the Ford dealer now

I just called Autozone and was told they couldn't recharge that kind of battery due to it being apart of a hybrid system and they aren't permitted to work with them
I just had my oil changed yesterday and I have the same problem you're having. Cars been charging fine holding a charge overnight no problems till I got my oil changed then the problem occurred everything's cleverything's clean no corrosion anywhere ....why?
