Hello everyone, brand new member here - happy to join the community. I have a one month old 2023 wrangler 392 and the battery light has been coming on intermittently for the past week. When I check the charging voltage it is charging at 15.1 to 15.4 volts…apparently over charging, triggering the light. If I let it idle it stays at that voltage but will (every 30 seconds or so) drop down to 13.4 volts and immediately go back up to 15.3 or 15.4 volts (without any change in engine RPM). The next time that I drive the car, the light will be out and the voltage reads the normal 14 to 14.5 volts. I know that if the light is not on when I take it in for service they will tell me they need it to happen to properly diagnose the issue (my code reader sees no trouble codes). I am guessing that it is a bad regulator chip in the PCM and the PCM would therefore need to be replaced to remedy the issue but admittedly it’s just a guess at this point. Have any of you experienced or heard of this issue and if so what is the fix? Thanks.
