Noticed the Stop/Start feature has not kicked in over the past week. Checking the status on the information display and it says this is because the battery is charging - even after a 25-30 mile journey. Checked the battery voltage with engine running - 14.4v but with engine not running it shows 12.2v - just wondering if the battery is failing ? Jeep is a 2017 Summit so battery may be about 5 years old. Any thoughts ?

At five years old I would say that the battery is very likely to be failing.
