Problem
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.
Risk
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.
Fix
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.

NHTSA campaign 17V571000 · 814 vehicles

Problem
Nissan North America (Nissan) is recalling certain 2017 Infiniti Q50 and Q50 Hybrid vehicles. The driver's frontal air bag inflator may have been improperly welded.
Risk
In the event of a crash necessitating deployment of the driver's frontal air bag, the inflator may crack and release the gas needed to properly deploy the air bag, increasing the risk of injury.
Fix
Nissan will notify owners, and dealers will replace the driver side air bag inflator, free of charge. The recall began October 30, 2017. Owners may contact Infiniti customer service at 1-800-662-6200, option 7.
Electrical System › Software · Jul 27, 2017

NHTSA campaign 17V476000 · 14,192 vehicles

Problem
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.
Risk
An engine stall can increase the risk of a crash.
Fix
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.
Air Bags › Sensor › Occupant Classification · Apr 26, 2016

In these vehicles, the front seat passenger Occupant Classification System (OCS) may incorrectly classify an adult passenger as a child or classify the seat as empty despite it being occupied. As a result, the passenger frontal air bag may be turned off and not deploy in the event of a crash.
Risk
If the passenger frontal air bag does not deploy as intended in the event of a crash, the passenger is at an increased risk of injury.
Fix
Nissan will notify their owners. Chevrolet City Express owners will be notified by General Motors. Dealers will reprogram the Air Bag Control Unit (ACU) and OCS Electronic Control Unit (ECU) in Altima, Maxima, Murano, Rogue, and Sentra vehicles, and replace the OCS ECU in LEAF, NV200, NV200 Taxi, Pathfinder, Infiniti Q50, JX35, and QX60 and Chevrolet City Express vehicles, free of charge.

  1. Run the VIN at nhtsa.gov/recalls. 4 recalls this year — ask for proof of repairs.
  2. Engine — 17 owner reports. Cold-start the engine, listen for knocking, and watch for warning lights or hesitation on acceleration.
  3. Air Bags — 10 owner reports. Confirm the airbag warning light turns off after start-up and any airbag recall was completed.
  4. Electrical System — 8 owner reports. Test every window, lock, light, screen and USB port; check the battery age.
  5. Mileage to watch. Owners typically reported problems around 29,000 miles; ask what was repaired near that point.
  6. Hybrid system. Check for hybrid-system warning lights and ask whether the high-voltage battery has been replaced or is still under warranty.
