This is my second 2017 QX50. Bought a Base 2WD Oct. of 2017 and totaled it in December. Found an AWD w/Premium and touring pkg. <9000 miles last week and own it now. One question though - the driver door switch that locks/unlocks the doors. On my car only the locked padlock icon lights up at night. Will someone look at theirs and let me know if I need to take it to a dealer for warranty replacement?
