The PCM modules available from US Alternators in Landyacht318’s link look really interesting. Unfortunately, it doesn’t look like they have one for any Jeep products. That’s too bad, because that would be the best way to address this problem IMO.
I can certainly understand your desire to replace the OEM battery setup with something more robust and reliable. To be honest, the OEM system sounds like a trouble prone POS. You would think a vehicle that comes with AGM batteries would have a charging system capable of charging them properly. But then, I also think that if Genesis is going to market a replacement battery system for the Jeep, it should work with the Jeep charging system.
Good luck, and please let us know what you do and how it works out.
