Nissan North America, Inc. (Nissan) is recalling certain 2020-2026 Nissan Armada, 2011-2013 Infiniti QX56, and 2014-2027 QX80 vehicles equipped with 22" wheels. The Gross Axle Weight Rating (GAWR) listed on the certification label is incorrect, which can allow the vehicle to be overloaded. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 110, "Tire Selection and Rims."
Nissan North America, Inc. (Nissan) is recalling certain model year 2012-2014 Nissan Juke, 2012-2013 Infiniti M56, QX56, and 2014-2015 Infiniti Q70 (V8 engine vehicles only), and QX80 vehicles. The fuel pressure sensors may not have been sufficiently tightened during production. As a result, the fuel pressure sensor may loosen with vehicle usage and cause a fuel leak.

(Nissan) is recalling certain model year 2013 Infiniti QX56 vehicles manufactured September 1, 2012, to April 26, 2013, and 2014 Infiniti QX80 vehicles manufactured June 18, 2013, to February 11, 2014.

Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“I starting hearing a grinding noise coming from engine couple of weeks ago. Took it to the Infinity dealership for a diagnostic test. The mechanic stated “ timing chains were found to be stretched and metal was worn.” This is the same issue which prompted the recall of 2011-2013 QX56 models. However, I did not own my vehicle during the recall period.”
“I apologize in advance if I’m not using the correct form to find out this information, hopefully if this does not reach correct person you can get to correct person for me. There has been a constant gas smell coming from gas tank area since we purchased vehicle in 2/2026. I thought it was just fumes from adding fuel but have since (while reaching in to retrieve grandbaby from back seat, I noticed a strong smell reaching towards driver door and a slight gas smell reaching inside vehicle. We have not been able to locate a gas leak anywhere just the strong gas smell. I’m trying to find out if this is a common occurrence for this vehicle or if there is a recall on it for this problem. Also if there has been a recall is there a way I can find out if the recall has been repaired. Thanks for any information you can provide.”
“The contact owns a 2014 Infiniti QX80. The contact stated that while driving 55-60 MPH, the service engine light illuminated. The vehicle was taken to a non-Infiniti dealer, where it was diagnosed that the high-pressure fuel pump had failed. The vehicle was repaired. The contact stated that the failure persisted. Most recently, the vehicle was vibrating abnormally. The vehicle was taken back to the non-Infinity dealer, where it was diagnosed that the bucket light cylinder near the camshaft had failed. The vehicle was not repaired. The contact related the failure to NHTSA Campaign Number: 14V683000 (Fuel System, Gasoline); however, the VIN was not included.
