Hello .. best way to introduce yourself to a new forum is to gave information !
i have a 2015 Leaf whos waranty just tresspass (basic 3 years 60 000km)
suddunly, one day, all radiator fan kick in 100% while driving or charging
even if i did not ask any AC task ... car inverter dead cold...
then find other user that had to get the coolant sensor replaced...
part number is 22630 3NAOA and cost 30$us (up to 60$cad ! )
to change this sensor yourself , if your warranty cannot work ,
you need to access below the windshield washer fluid filling area:
1--unplug 12v battery ground (might prevent ECM dammage ? )
2--remove the charge port door , 4 little screws

, need to split the cover wings around the charge port to exit charge port door inge
4--to keep all coolant liquid in , ask for help while doing the
5--release coolant pressure , removing coolant cap
6--unscrew the old sensor and ask your partner to swap the
oring to the new sensor while you block coolant port with
7--install the new sensor WITH the oring and gently screw it back
