My OEM battery (2019) died this fall. Replaced with a top-rated DieHard AGM. It died 3 times in 3 weeks-- and it wasn’t the charging system/alternator… …and it wasn’t the battery – I had a PCM code and BCM code and something about a fuse. There must be scenarios where persistent issues drain the battery until resolved. Today all that is cleared up now, and I’m holding my breath to see if the battery holds up as expected.

btw, I have an 8-stage smart charger that can carefully recover for these situations (I bought for an RV battery issue).

Final PSA: If you have jumper cables or an emergency starter battery, keep them in the cab and not the trunk.

AGREE!! I have an PCM issue and it’s killing my battery until replaced-- where is my jump battery and cables? IN THE TRUNK THAT DOES NOT OPEN!! AARRGGHHH!
