    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."

    Risk: 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. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.

    Seat belts:front:anchorage

    Nissan North America, Inc. (Nissan) is recalling certain 2018 Infiniti QX30 vehicles. The bolt securing the right-hand side lower seat belt anchorage may have been incorrectly installed during production. This can result in the lower seat belt anchorage detaching in a crash. As such, these vehicles fail to comply with certain requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 210, "Seat Belt Assembly Anchorages", number 209, "Seat Belt Assemblies, and number 208, "Occupant Crash Protection."

    Risk: If the lower seat belt anchorage detaches in a crash, it can increase the risk of injury.

    Air bags:frontal

    Nissan North America, Inc. (Nissan) is recalling 2017-2018 Infiniti QX30 vehicles. The driver's air bag may unexpectedly deploy due to insufficient grounding of the steering components if an electrostatic discharge occurs and the air bag clockspring is broken.

    Risk: If the driver air bag inadvertently deploys, it can increase the risk of injury and a crash.

    Remedy: Nissan will notify owners, and dealers will add sufficient grounding to the steering components, free of charge. The recall began March 26, 2018. Owners may contact Infiniti customer service at 1-800-622-6200, option 7.
