So a while ago I noticed that my Auto stop start was no longer working. Took it to ford, they tested my battery and replaced it. Stating it failed a rotunda test. Fast forward today and i'm seeing the same issues. With the battery being only 2 months old I was reluctant to blame the battery but I started monitoring SOC and voltages like a hawk because the ford dealerships around me a horrid (they already said my voltage is "within normal spec.")
Here's a timeline:
Last night battery was at 76% after driving 1hr.
This morning battery is at 60% and 11.8V
Drive 15 min to orielly to test the battery, stop at their lot and im at 68% 12.1v
They test it, found good and recharge. their tester says 62%
Leave there, drive 15 min to Napa, check myself and it says battery is now 59% with 12.3v on the battery
They test it and report 52% SOC battery good an recharge.
Any idea what could be going on here? im at my limit with knowledge on this matter and wondering what the issue could be?
Also I do have a B162F trouble code. There's an SSM for it which dealership has performed at least 3 times which is to reprogram the BCMC module but it doesn't fix it. the B162F is a "VDM circuit open" message. Could this cause a drain or an issue charging?
