Can I fix my 2014 car to supply power after I turn off ignition?

I have a 2014 Nissan Rogue Select and when I turn off the ignition I lose power to the radio and anything plugged into the cigarette lighter ports. My 2008 Ford Escape let the radio play for 20 minutes and let things keep power/charging that were plugged in. I liked that feature and would like to see if its possible to "fix up" my newer car like that?

I would not go messing with the electrical system in a car that is still under warranty, if you screw something up they won't cover it.

Your car has an accessory position (every car does), between the off and the running position. From there the car will not run, but it will keep your power ports and radio working, you just have to leave the key in the ignition.

Don't mess with it. The car's computer won't like the change.

Nothings wrong with it. Just turn the key to the ACC or On position, it will keep the power on until you turn key to off position. Just be aware that you might drain your battery if you are running multiple devices while your engine is not running.
