2019 Infiniti QX50 recalls
3 NHTSA recall campaigns list this model year.
- NHTSA 25V437000Jun 27, 2025Engine443,899 vehicles
Engine and engine cooling:engine:hard parts internal/mechanical
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.
Remedy: 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.

Back over prevention: sensing system: camera
Nissan North America, Inc. (Nissan) is recalling certain 2018-2019 Nissan Altima, Armada, Frontier, Kicks, Leaf, Maxima, Murano, NV, NV200, Pathfinder, Rogue, Rogue Sport, Sentra, Titan, Titan Diesel, Versa Note and Versa Sedan vehicles, as well as Infiniti Q50, Q60, QX30 and QX80 vehicles. Additionally included are 2019 Nissan GT-R and Taxi and Infiniti QX50, QX60, Q70, Q70L vehicles. The back-up camera and display settings can be adjusted such that the rear view image is no longer visible and the system will retain that setting the next time the vehicle is placed in reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 111, "Rear Visibility."
Risk: The lack of an image in the back-up camera display increases the risk of a crash.
Remedy: 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
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.
Remedy: 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.
