3 recalls.

24V470000

Date: 2024-06-21. Systems: POWER TRAIN.

Defect: 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.

Consequence: The lack of an image in the back-up camera display increases the risk of a crash. (excerpt)

17V476000

Defect: 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.

Remedy: 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.

Notes on this record

  • Complaints from the API and bulk file are merged and deduplicated by ODI number; the API alone misses records.
  • System and subsystem counts are numbers of distinct complaints, recalls or communications that name them. One record can name several systems, so shares across systems can add to more than 100 percent; a single share never exceeds 100 percent.
  • Recalls are counted once per campaign, investigations once per action and manufacturer communications once per NHTSA id, even when NHTSA lists several model names for the same record.
  • A sales denominator is a calendar-year proxy, not the population of vehicles still in use. Rates are copied from verified pipeline output.
