2011 INFINITI QX56 Problems

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.

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 contact owns a 2011 Infiniti QX56. The contact stated while driving approximately 25 MPH, the vehicle began to shake and inadvertently stalled. The check engine warning light was illuminated. The vehicle was taken to a local dealer where it was diagnosed with needing the high-pressure fuel tank replaced. The vehicle was repaired however, the failure persisted. The manufacturer was not informed of the failure. The failure mileage was approximately 148,000.

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.

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.

WINDSHIELD CRACKS - I'VE BEEN THROUGH 3 WINDSHIELDS ON THIS VEHICLE - ALWAYS BREAKS IN SAME SPOT: DRIVERS SIDE, UNDER WIPERBLADE, NEAR THE CORNER BY THE VIN PLATE. FIRST TIME THERE WAS NO BULLSEYE, CHIP, OR EXTERNAL DAMAGE, BUT DEALER STILL WOULD NOT COVER IT. SECOND TIME WAS AFTER A MINOR IMPACT WITH FRONT BUMPER. THIRD WAS A ROCK HIT, BUT ALL THREE HAD THE BREAKAGE IN THE SAME SPOT! I NOTICED OTHER COMPLAINTS, SO CLEARLY THIS ISN'T A RANDOM OCCURRENCE.

FRONT WIND SHIELD CRACKS WITH THE SLIGHTED HIT ON MY SECOND ONE IN THREE MONTHS. IF IT CAN NOT WITHSTAND ROAD DEBRIS IMAGINE A CAR ACCIDENT. *TR

TRAVELING AT 1 MPH, MY 2011 INFINITI QX56 BUMPED ANOTHER VEHICLE. THERE WAS NO DAMAGE TO EITHER VEHICLE, BUT MY DRIVER AIRBAG DEPLOYED. INFINITI IS REFUSING TO LOOK AT THE VEHICLE UNLESS MY INSURANCE COMPANY ASKS THEM TO. I FEEL THIS LOW SPEED DEPLOYMENT IS FROM A DEFECT IN THIS WEEK OLD VEHICLE, BUT CANNOT GET HELP. I AM CONCERNED INFINITI IS ATTEMPTING TO IGNORE THE PROBLEM AND BRUSH IT UNDER THE RUG. *TR

WHEN DRIVING 40-70 MPH AND HITTING ANY ROAD IRREGULARITIES (OFFSETS IN PAVEMENT AT BRIDGES, OLD TO NEW PAVEMENT, MAN HOLE COVERS, ROAD PATCHES) THE VEHICLE BACK END SKIPS SIDEWAYS WITH A LOSS OF CONTROL. THE VEHICLE WILL START TO HEAD INTO THE NEXT LANE AND NEEDS TO BE STEERED IN THE OPPOSITE DIRECTION TO CORRECT IT. WE DO NOT FEEL SAFE DRIVING IT. OTHERS IN THE CAR HAVE SAID THEY HAVE NEVER EXPERIENCED ANYTHING LIKE IT. DEALERSHIP IS TELLING US THIS IS NORMAL. VEHICLE IS UNDER WARRANTY AND WE CAN'T GET RESOLUTION TO THIS. *TR
