NHTSA complaint #10914245, filed 2016-10

Electrical system: “3 of my vehicles doors do not unlock or lock using the key fob or the unlock/lock button on the door. This can be dangerous if you need to lock or unlock the doors in a hurry. It is a known issue in many Infiniti fx35/45 of this generation.”

NHTSA complaint #11327500, filed 2020-06, 91,000 miles

Latches, locks and linkages: “The lock actuator on the rear hatch broke and I was unable to close the hatch or lock the vehicle. After dissembling the actuator there was a small plastic pin that broke that prevented the latch from engaging. I then had to pay over $400.00 to have it replaced for a plastic piece that probably cost less than $1 to manufacture.”
