- Problem

- Risk
- An overloaded vehicle can increase the risk of a crash.
- Fix
- Dealers will install new labels, free of charge. Additionally, Nissan will mail replacement labels to owners. Interim letters notifying owners of the safety risk were mailed September 2, 2026. Additional letters will be sent once the final remedy is available, anticipated Fall 2026. Owners may contact Nissan customer service at 1-800-867-7669.

- Problem
- Nissan North America, Inc. (Nissan) is recalling certain 2025 Murano, 2025-2026 Armada, and Infiniti QX80 vehicles. A software error may occur in the In-Vehicle Infotainment (IVI) system at vehicle startup, resulting in the rearview camera image not displaying when the vehicle is shifted into reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
- Risk
- A rearview image that does not display reduces the driver's view behind the vehicle, increasing the risk of a crash.
- Fix
- The IVI system software will be updated by a dealer, or through an over-the-air (OTA) update, free of charge. Owner notification letters were mailed February 2, 2026. Owners may contact Nissan's customer service at 800-647-7261 or Infiniti's customer service at 1-800-662-6200. Nissan's numbers for this recall are R25D6, R25D5, and R25D7.
