2015 Nissan Versa USB port not working

most likely it's a bad battery, one who stopped taking a re-charge from your alternator after 5-7 years, if parked outside, hungry rodents can nibble the vinyl wiring, that's my only guess....tidy up the black connections off of the battery~

2015-2023 = nine years

after 5-7 years the tin-antimony alloy batteries will stop taking a charge, operate at reduced amperage and voltage, and battery connections need tending to, washing off the corrosion and testing the voltage for leaky cables/wires~ voltage drop can make relays not work anymore~ thermal cycling can create corrosion, in an otherwise dry environment~

parked outside? rodents will chew through wires, then they do not work anymore~
