- Summary
- Nissan North America, Inc. (INFINITI) is recalling certain 2011-2013 M56, 2012-2013 M35 Hybrid, 2014-2018 Q50, Q70 Hybrid, 2014-2019 Q70, and 2015-2019 Q70L two-wheel drive vehicles. The driveshaft can fatigue and break.
- Consequence
- A broken driveshaft can result in a loss of drive power, or a vehicle roll away when the vehicle is in park without the parking brake applied. Both scenarios can increase the risk of a crash.
- Remedy
- Dealers will replace the driveshaft, free of charge. Owner notification letters were mailed August 13, 2024. Owners may contact INFINITI's customer service at 1-800-662-6200. INFINITI's numbers for this recall are R24A5 and R24A7.
No Back-Up Camera Display Image/FMVSS 111
- Summary
- 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."
- Consequence
- 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.
Fuel Pump Control Module Software may cause Stall

- Consequence
