Safety recalls (2)

Equipment:other:labels 2026-07-15 · campaign 26V455000 · 168,149 vehicles

Defect: 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.

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. 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 Ju

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.
