Rear-visibility system issue
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."
Consequence
The lack of an image in the back-up camera display increases the risk of a crash.
Full campaign recordRemedy
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 may fail
FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP
Nissan North America, Inc. (Nissan) is recalling certain 2016-2018 Infiniti Q50 and 2017 Infiniti Q60 vehicles equipped with a 2.0L engine. Incorrect Fuel Pump Control Module (FPCM) software may allow the fuel level in the main tank to be too low to supply fuel to the engine, causing the engine to stall while driving.
Consequence
An engine stall can increase the risk of a crash.
Full campaign recordRemedy
Nissan will notify owners, and Infiniti dealers will reprogram the Fuel Pump Control Module (FPCM) with corrected software, free of charge. The recall began August 29, 2017. Owners may contact Infiniti customer service at 1-800-662-6200.

Driveshaft bolt issue
POWER TRAIN:DRIVELINE:DRIVESHAFT
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.
Full campaign recordRemedy
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.

What the ratings mean
NHTSA published rollover resistance for this vehicle but not frontal crash, side crash and side pole. An untested area is not a poor result — it means no published data exists, and the overall star rating is calculated without it.
NHTSA's dynamic test put this vehicle's rollover probability at 9.7% in a single-vehicle crash — the figure behind the rollover star rating, published here because the star alone hides how wide each band is.

How this compares
At 23 MPG combined, the 2018 Infiniti Q50 ranks 19th of 24 midsize cars EPA rated for 2018 — 3.5 MPG short of the 26.5 MPG median for that group.
That places it among the thirstiest vehicles in its class. If annual mileage is high, the running-cost gap against a class-average rival compounds quickly.
EPA puts annual fuel spend at about $3,300, $700 more than the $2,600 typical for the class. Over five years at 15,000 miles a year that is roughly $16,500, a $3,500 difference against a class-median vehicle.
Tailpipe CO₂ is 387 grams per mile — about 5.8 metric tons over 15,000 miles of driving.
