BACK OVER PREVENTION: SENSING SYSTEM: CAMERA · Campaign 19V654000 · Sep 13, 2019
Defect: Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Consequence: The lack of an image in the back-up camera display increases the risk of a crash.
Remedy: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated.
