NHTSA 25V437000 Reported Jun 27, 2025

Filed by: Nissan North America, Inc. (manufacturer recall no. R25A8/A9 R25B1/B2/D1)
Units affected: 443,899 (estimate)
Problem: Nissan North America, Inc. (Nissan) is recalling certain 2021-2024 Rogue, 2019-2020 Altima, 2019-2022 Infiniti QX50, and 2022 Infiniti QX55 vehicles equipped with 3-cylinder 1.5L or 4-cylinder 2.0L variable compression turbo (VC-Turbo) engines.

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 R25A8/A9 and R25B1/B2.

Problem: 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.
