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.
