2018 Chrysler Pacifica - Charging system warning

charging system service light in dash

I am not a mechanic but I suspect your battery is going bad. Have it and the alternator tested.


Well, I would check the charging system, battery and alternator as @davepsinbox_157004 recommends. If you are in the US many McParts stores (Advance, AutoZone etc) will check for free.

So very simple, have your charging system serviced (checked) and repair/replace as necessary.
Or you can ignore until it dies and have it towed.

Additionally, I would be willing to bet at least the price of a cup of coffee that all of the preceding advice is mentioned in the Owner’s Manual. It might be instructive for the OP to take a look at that manual.
