Recall 26V455000168,149 vehicles

Problem: 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."
Risk: An overloaded vehicle can increase the risk of a crash.
Fix: Dealers will install new labels, free of charge. Additionally, Nissan will mail replacement labels to owners. Interim letters notifying owners of the safety risk were mailed September 2, 2026. Additional letters will be sent once the final remedy is available, anticipated Fall 2026. Owners may contact Nissan customer service at 1-800-867-7669. Nissan's numbers for this recall are R26B1 and P6A13/4. Vehicle Identification Numbers (VINs) involved in this recall became searchable on NHTSA.gov on July 16, 2026.

Need to know if there are recalls on the Q56 Infinite for the Catalytic Converter Failure. This truck had 2 and this is the second one that seems to be faulty and the truck only had 162000 miles The 1st one faulted at 151000 2024 The Infinite 2011 Q56 has been known for faulty Catalytic Converter Failure and nothing was done to recall and fix. The truck had 2 Catalytic Converters, the 1st one went out in 2024 @ 152000 miles, now it looks like my engine light is back on with error code P0420 Converter malfunction. I searched internet and it was noted that 2011 have had enormous reports about this issue. This doesnât make since there is no recall when it is noted that the 2011 Q56 had…

Suspension
A subframe is a key structural component of every car. As such, it stands to reason that it should last as long as the car itself. Doing much research on this model suspension and subframes become rusted as I didnât know this when purchasing making it very unsafe . I experienced being involved in almost 2 accidents. Very dangerous. Subframe split in half and suspension. Something needs to be done as a lot of people are going thru this issue and Infiniti slogan claims ânew horizonsâ by no means new horizon going to heaven by driving their vehicles.

Fuel/propulsion system
Catalytic Converter, A/F Sensor failed on the interstate when I was driving with kids in the car. Took vehicle to the nearest dealer only to be told that this is a known problem with these vehicles and it was going to cost me $3,100 to repair.

Suspension
The rear controls arms and cradle mount were riddled with severe fissures, causing car to sway dramatically. The level of component failure posed a severe safety risk to me. My mechanic was shocked by the amount of failure to these major rear suspension components. I have included photos and receipts for repairs.

I'M CURRENTLY DEALING WITH THE TIMING CHAIN NIGHTMARE SO MANY OTHERS HAVE HAD AND ARE HAVING. OF COURSE JUST AS MOST OF THE OTHERS I'M OUT OF WARRANTY AND REALLY FRUSTRATED THAT INFINITI HASN'T STEPPED UP TO THE PLATE TO ADDRESS THE PROBLEM PROPERLY AS OPPOSED TO RENAMING THE QX56 TO QX 80 TO SAVE THEMSELVES, LEAVING CONSUMERS SCRAMBLING WITH EXPENSIVE TIME CONSUMING FIXES TO A KNOWN DEFECT ON THEIR PART. WHERE'S THE ACCOUNTABILITY ON THEIR PART, DO A CERTAIN NUMBER OF PEOPLE HAVE TO DIE OR BE INJURED BEFORE THE CONSUMERS ARE PROVIDED WITH THE PROPER ASSISTANCE? WHO REALLY LOOKS OUT FOR US? A recall was done in 2016 obviously they need to expand the Vin number
