Within that volume, owners reported 0 crashes, 3 fires, 0 injuries, and 0 fatalities. No NCAP 5-star crash-test rating is available for this model year in the federal database.
Component-level analysis is where model-year complaints become actionable: the top complaint category for the 2011 QX56 is engine with 37 filings, followed by fuel/propulsion system (18) and suspension (9). Concentration in one or two component groups is the classic signature of a systemic defect; a flat distribution usually reflects normal aging, warranty complaints, or isolated build-plant variability. This model year has 1 active recall campaign, which means the manufacturer is obligated to remedy the covered defect at no charge for the life of the vehicle — the full NHTSA campaign numbers are listed below.
NHTSA currently has 7 investigation files overlapping the 2011 QX56. Owners comparing this cohort against neighboring years should pair the counters above with the complaint-by-year trend on the parent model page — a spike in a single year often tracks to a platform refresh, a new transmission supplier, or an updated ECU calibration.

Nissan North America, Inc. (Nissan) is recalling certain 2012-2017 NV Cargo and NV Passenger Van, 2013-2015 Titan and Armada and 2011-2012 Infiniti QX56 vehicles. Due to a manufacturing issue, the air bag inflator may not function properly or may rupture during deployment.
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.
Unknown. Timing chain issue. When car is started it makes a noise for about 10 min then goes away
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.

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
