I have a 2014 1LT V6...I decided to replace the original battery before it gets too cold out, so I replaced it with a 'Platinum' AGM battery from Advance auto.
It has been running 15 to 15.3 volts almost always [all week] as well as periodically flashing the check engine light. I bought a cheap OBD 2 reader
and I get the following codes ; P1682 Driver 5 / Line 2 and code P2535
Ignition 1 switch circuit high voltage {PCM]
From research one says to replace ignition switch / other says to replace the
PCM/ECM . I'm not sure what I did wrong replacing battery, and I dont want to keep replacing parts. Car was fine until the battery swap. Tried to reset/flash
with battery disconnect and fuse pull..still overcharging.
PLEASE HELP / MY ONLY CAR. THANK YOU!

Take it back where you got the battery and have them test it. You may have gotten a bad one, they should exchange it if so. It's not all that uncommon.

The battery is in a low state of charge. Mine will charge at 15.1-15.2v when i dont drive it for over a week. It can stay that way until i take like a 1 hour drive. Try placing it on a battery charger. Once the batt is charged the voltage will drop to 14.8 then down to 12.5-12.6V. these charging systems are not like the old 13.8 all the time.
