14 JGC Overland 4x2 5.7 - low voltage warning

Erratic voltage spikes have been giving me fits lately: low voltage warning and DTC stored codes that report overcharging at same time. Dealer finally replaced the alternator, battery, PCM module plus updated all software to latest version after previous work orders failed to fix the same problem. Namely the TSB Recall and a routine check and tightened all grounds.

I will report back with status.
