Yes they do. Should be on the Rubicon not sure about Sports.

The “Oil Change Required” message
will display in the instrument cluster display for five sec-
onds after a single chime has sounded to indicate the
next scheduled oil change interval. The engine oil
change indicator system is duty cycle based, which
means the engine oil change interval may fluctuate,
dependent upon your personal driving style

Here's the extract from p. 113 of the 2021 Owner's Manual PDF:

OIL CHANGE RESET — IF EQUIPPED
Your vehicle may be equipped with an engine oil
change indicator system. The “Oil Change
Required” message will display in the
instrument cluster display for five seconds after
a single chime has sounded to indicate the next
scheduled oil change interval. The engine oil
change indicator system is duty cycle based,
which means the engine oil change interval may
fluctuate, dependent upon your personal
driving style.
Unless reset, this message will continue to
display each time you place the ignition in the
ON/RUN position.


Here's some real nanny BS from p. 119, as it applies to diesel owners. Emphasis mine.

NOTE:
Failing to follow the oil change indicator,
changing your oil and resetting the oil change
indicator by 0 miles (0 kilometers) remaining
will prevent the diesel exhaust filter from
performing its cleaning routine. This will shortly
result in a Malfunction Indicator Light (MIL) and
reduced engine power. Only an authorized
dealer will be able to correct this condition.


OP: RTFM.

I believe it's when you have either 5 or 10% left on the indicator that it will also start showing a warning as mentioned.

Even though my dealership says it only needs to be changed every 6K miles, mine is dirty at 3K miles so it gets changed then no matter what the percent says and long before there is any warning.
