[2018JEEPGRANDCHEROKEEMAN]

The Stop/Start feature on my 2018 Jeep Grand Cherokee Limited quit working. The Dash says that the Battery is still charging. I know it is the Auxiliary Battery that runs the Stop/Start feature. So I removed the battery and had it checked at my local Advanced Auto store. It checked good under load and charging so I put it back. The charging system is good because the Main Battery shows 14 Volts.

So what else can I look for to check why the Stop/Start is not working???

Thanks in advance

Well I'd start with the switch. The light can give false indication. You''ll need a print of course. If I remember correctly the start stop doesn't work when the engine is cold.
