Have a 2013 Dodge Charger SE, 3.6
we have replaced the following: water pump, thermostat, radiator, and had the complete system flushed.
Am at crossroads trying to figure this out!

 

Ghost -

Are you sure it's over heading?
The t-stat/temp sensor can be flaky, has the check engine light been on?
If you're going by the gauge only, get an IR thermometer and confirm.

If that's not it, there might a restriction somewhere in the engine, despite the flush.

Test the cooling fan system....
