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 doesn’t make since there is no recall when it is noted that the 2011 Q56 had history of faulty Catalytic Converter Failure. This cost to replace and repair is enormous and this type of part replacement repair should not be happening at 152000-162000 miles. This needs to be investigated and recall issued immediately.

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 didn’t know this when purchasing making it very unsafe . I experienced being involved in almost 2 accidents.

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 didn’t 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 “new horizons” by no means new horizon going to heaven by driving their vehicles.

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.

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
