Back Over Prevention:display Function 2021-08-02 · campaign 21V599000 · 3,569 vehicles

Defect: Nissan North America, Inc. (Nissan) is recalling certain 2021 Infinity Q50, Q60, and QX80 vehicles. A software error may deactivate the audio/video control unit screen, preventing the rear-view image from displaying. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility."

Risk: A rear-view camera that does not display an image reduces the driver's rear view, increasing the risk of a crash.

Fix: Dealers will update the control unit software, free of charge. Owner notification letters were mailed September 14, 2021. Owners may contact Nissan customer service at 1-800-867-7669. Nissan's number for this recall is R21A9.

Suspension:rear:axle:spindle 2021-05-27 · campaign 21V402000 · 14,276 vehicles

Defect: Nissan North America, Inc. (Nissan) is recalling certain 2020 Nissan Murano, INFINITI QX60, 2021 Nissan GT-R, INFINITI QX50, and Q50 vehicles. The front steering knuckle or rear axle housing may have insufficient strength due to improper heat-treatment.

Risk: The steering knuckle or rear axle could deform upon impact, such as from hitting a curb, resulting in a loss of steering control, or possible wheel separation. Both of these conditions can increase the risk of a crash.

Fix: Dealers will inspect and replace the front steering knuckle and rear axle housing, as necessary, free of charge. Owner notification letters were mailed July 26, 2021. Nissan owners may contact customer service at 1-800-867-7669. INFINITI owners may contact customer service at 1-800-662-6200.

Engine And Engine Cooling:engine:engine Control Module (Ecu/Ecm):software 2021-04-04 · campaign 21V234000 · 12,943 vehicles

Defect: Nissan North America, Inc. (INFINITI) is recalling certain 2021 INFINITI Q50 and Q60 vehicles. After detecting rapid acceleration, the Engine Control Module (ECM) may incorrectly reduce engine power and reduce fuel supply to the engine.

Risk: A lack of fuel may cause an engine stall, increasing the risk of a crash.

Fix: INFINITI will notify owners, and dealers will reprogram the ECM software, free of charge. The recall began on May 25, 2021. Owners may contact INFINITI customer service at 1-800-662-6200. INFINITI's number for this recall is R20C5.

Service bulletins (111)

Technical service bulletins are repair instructions manufacturers send dealers for known issues. Unlike recalls, the fix is not automatically free — but naming the bulletin at the service desk can save diagnosis time and support goodwill repairs.
