ELECTRICAL SYSTEM:IGNITION

Summary: Nissan North America, Inc. (Nissan) is recalling certain 2017 Nissan NV200, Sentra, NV3500 Van, NV3500 Bus, NV200 Taxi, NV1500, NV2500 Van, Chevrolet City Express, 2017-2018 Frontier, Versa Note, and Versa Sedan vehicles that have a mechanical (physical) key ignition system. In these models, over time, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position to the accessory position, turning off the engine.

Safety Consequence: If the vehicle stalls, it can increase the risk of a crash.
Manufacturer Remedy: Nissan will notify owners, and dealers will inspect the production information on the ignition switch, and replace it as necessary, free of charge. The recall began October 1, 2018. Owners may contact Nissan customer service at 1-800-867-7669.
NHTSA Campaign #19V654000Reported: 12/09/2019

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Summary: 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."

Safety Consequence: The lack of an image in the back-up camera display increases the risk of a crash.
Manufacturer 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. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.
