water pump turning on after shutoff

I've read the n55 guys having this problem but has anyone had this issue with the water pump running way too long after the car is shutoff?

Sometimes when I shut the car off, get out, close the door, wait for the start/stop button to turn off.....5 seconds later the water pump starts running....the engine is not that hot when it happens...I did notice when it happens the gear level indicator stays lit on park when the start/stop button turns off....still running and it's been 1/2 hour...Help.
