Engine And Engine Cooling:engine:hard Parts Internal/Mechanical 2025-06-27 · campaign 25V437000 · 443,899 vehicles

Defect: 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.

Risk: The lack of an image in the back-up camera display increases the risk of a crash.

Fix: Nissan will notify owners in phases, having dealers update the back-up camera settings software, free of charge. The recall began November 11, 2019 and all affected VINs should be activated. Owners may contact Nissan customer service at 1-800-867-7669 or INFINITI customer service at 1-800-662-6200.

Air Bags:knee Bolster 2018-09-06 · campaign 18V593000 · 1,671 vehicles

Defect: Nissan North America, Inc. (Nissan) is recalling certain 2019 INFINITI QX50 vehicles. In the event of a crash in very cold temperatures, the trim cover may separate unexpectedly from the passenger-side knee air bag module instead of splitting at the trim cover tear seam as designed.

Risk: If the passenger-side knee air bag cover detaches during deployment, it can increase the risk of injury.

Fix: INFINITI will notify owners, and retailers will replace the passenger-side knee air bag module, free of charge. The recall began October 23, 2018. Owners may contact INFINITI customer service at 1-800-662-6200.
