Tap a recall to see the problem, the risk and the fix.

Engine and engine cooling:engine:hard parts internal/mechanicalJun 27, 2025 · NHTSA campaign 25V437000 · 443,899 vehicles

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. The engine bearings may have manufacturing defects that can lead to engine failure.

Risk: Engine failure increases the risk of a crash. A bearing failure may cause a breach in the engine block, allowing hot oil to be discharged, increasing the risk of an engine fire.

Fix: Dealers will reprogram the engine control module (ECM) software, free of charge. Owner letters were mailed April 8, 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 R25A8/A9 and R25B1/B2.

Suspension:rear:axle:spindle; steering:linkages:knuckle:spindle:armMay 27, 2021 · NHTSA campaign 21V402000 · 14,276 vehicles

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.

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.
