2015 Infiniti QX80 recalls

2 NHTSA recall campaigns list this model year.

  1. NHTSA 26V455000Jul 15, 2026Other168,149 vehicles

    Equipment:other:labels

    Nissan North America, Inc. (Nissan) is recalling certain 2020-2026 Nissan Armada, 2011-2013 Infiniti QX56, and 2014-2027 QX80 vehicles equipped with 22" wheels. The Gross Axle Weight Rating (GAWR) listed on the certification label is incorrect, which can allow the vehicle to be overloaded. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."

    Risk: An overloaded vehicle can increase the risk of a crash.

    Remedy: 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. Nissan's numbers for this recall are R26B1 and P6A13/4. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on July 16, 2026.

  2. NHTSA 14V683000Nov 28, 2014Fuel System133,592 vehicles

    Fuel system, gasoline

    Nissan North America, Inc. (Nissan) is recalling certain model year 2012-2014 Nissan Juke, 2012-2013 Infiniti M56, QX56, and 2014-2015 Infiniti Q70 (V8 engine vehicles only), and QX80 vehicles. The fuel pressure sensors may not have been sufficiently tightened during production. As a result, the fuel pressure sensor may loosen with vehicle usage and cause a fuel leak.

    Risk: A fuel leak in the presence of an ignition source could cause a vehicle fire.

    Remedy: Nissan will notify owners, and dealers will re-torque the fuel pressure sensors free of charge. The recall began on January 25, 2015. Owners may contact Nissan customer service at 1-800-647-7261.
