Thanks for the information. I just yesterday bought a 2016 QX60 and was planning to order the parts while Infiniti has the 25% off sale on their parts website.I returned 999T5RZ040 to my dealer. They did some research, and have now ordered PN 999T5R4190. Same description 'TOW HITCH FINISHER'.
I can not find 999T5R4190 on Infiniti website, how did you order it?
