The contact owns a 2011 Infiniti QX56. The contact received notification of NHTSA Campaign Number: 26V455000 (Equipment); however, the part to do the recall repair was not yet available. The contact was unable to rent the vehicle. The local dealer was contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.

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. 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.

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

1.-THE DASH BOARD IS UNLEASHING BY THE SUN. ( MELTING ) 2.-THE PAINT IS RISING MY SUV JUST HAVE 70K MILES IT 2011 ( TO DAY OCT 03/2019)

A CHECK ENGINE LIGHT (CEL) APPEARED ON MY 2011 INFINITI QX56 AT 89K MILES. ERROR IS A BAD CATALYTIC CONVERTER ON BANK 1. THE EXACT MESSAGE ON ODB2 READER IS: P0420 CATALYST SYSTEM EFFICIENCY BELOW THRESHOLD BANK 1. THIS ISSUE JUST HAPPENED AFTER I JUST REPLACED A BAD O2 SENSOR AFTER A CEL.

LESS THAN A YEAR AFTER I GOT THE TIMING DEBACLE FIXED, I GET A "CHECK ENGINE LIGHT" ON 2011 QX56. ACCORDING TO MY WARRANTY APPROVED MECHANIC BOTH CATS WERE GONE AND WERE NOT COVERED. THIS COMPLAINT IS THE BEGINNING OF MY GOAL OF GETTING ASSURANT OR INFINITI TO OWN THIS PROBLEM SINCE THE COMBINED CA AND FED CAT WARRANTY IS 150K MILES. MY WARRANTY SHOULD COVER.

I PURCHASED MY 2011 INFINITI QX56IN JANUARY OF 2015 WITH 36,6036 MILES ON IT. I TAKE EXCELLENT CARE OF MY VEHICLE MECHANICALLY AND CLEANLINESS. ON AUGUST 17TH, 2019 MY BACK A FRAME AND OTHER REAR SUSPENSION BROKE DUE TO CORROSION AND THE METAL SPLIT APART. MY UNDER CARRIAGE ALSO LOOKS LIKE AND OLD CAR. MY CAR IS WASHED TWICE A WEEK EVEN IN THE WINTER TO REMOVE THE SALT. THIS IS NOT COVERED UNDER ANY OF MY WARRANTIES. IT IS GOING TO COST ME $5,200.00 TO MAKE THIS REPAIR. I HAD TWO CHEVY SUBURBANS THAT I PUT 295,000 MILES ON AND SOLD THEM TO FRIENDS AND THEY ARE STILL DRIVING THEM WITH NO ISSUES LIKE THIS. I WILL NEVER BUY A INFINITI AGAIN! I NOTICED THIS WHEN I WAS APPROACHING THE BACK OF MY VEHICLE AFTER PLAYING HOCKEY. SO IT MUST HAVE HAPPENED AFTER I PARKED THE CAR.

THE CATALYTIC CONVERTER BANK 1 NEEDS TO BE REPLACED. THIS SEEMS TO BE A COMMON ISSUE WITH TURN 2011-2013 INFINITY QX 56 AND INFINITY SHOULD HAVE ISSUED A RECALL FOR THE FAULTY CONVERTERS.

CATALYTIC CONVERTER ISSUES CAUSING THE CHECK ENGINE LIGHT TO COME ON

TL* THE CONTACT OWNS A 2011 INFINITI QX56. WHILE OPERATING THE VEHICLE AND DEPRESSING THE ACCELERATOR PEDAL, A SQUEALING AND CLAPPING TYPE NOISE WAS HEARD FROM THE ENGINE COMPARTMENT.

CATALYTIC CONVERTER BOTH SIDES NOT WORKING (112 K MILES). THIS IS A VERY PREVALENT (AND VERY EXPENSIVE) ISSUE IN MOST 2011-2013 QX56 (PLEASE SEE NHTSA COMPLAINTS AND INFINITI FORUM COMPLAINTS). IS THERE A RECALL OR WILL THERE BE ONE?

MY VEHICLE NEEDS TWO CATALYTIC CONVERTERS REPLACED IN ORDER TO PASS SMOG. INFINITI DEALER WANTS $5600 TO MAKE THIS REPAIR! THIS IS A COMMON PROBLEM FOR THIS VEHICLE AND SHOULD BE A RECALL ITEM.

THE SERVICE ENGINE SOON LIGHT CAME ON, AND I BROUGHT THE VEHICLE TO HOLMON INFINITI IN MAPLESHADE, NJ WHERE I PURCHASED THE VEHICLE. THE DIAGNOSIS WAS A BANK 2 CATALYTIC CONVERTOR FAILURE. I HAD IT REPLACED AT A COST OF $2,661.79 ON THURSDAY MARCH 29, 2018. ON SATURDAY MARCH 31, 2018, THE BANK 1 CATALYTIC CONVERTOR FAILED. INFINITI CONSUMER AFFAIRS PROVIDED SOME ASSISTANCE WITH THE SECOND REPAIR. THEY PAID FOR THE PARTS AND I PAID THE LABOR OF $1,385.63. INFINITI CONSUMER AFFAIRS WOULD NOT REIMBURSE ME FOR THE PARTS FOR THE FIRST REPAIR BECAUSE "I ALREADY PAID FOR IT". HAD I KNOWN ABOUT THIS APPARENTLY COMMON PROBLEM, I WOULD NOT HAVE PAID FOR THE FIRST ONE WITHOUT CONTACTING THEM FIRST. IT APPEARS TO BE A KNOWN ISSUE IF THEY WERE WILLING TO GIVE ME ANY ASSISTANCE AT ALL, AND I WOULD THINK THAT WOULD BE EXTENDED TO REPAIRS ALREADY PAID FOR BY THE CONSUMER.

INFINITI HAS NEVER OFFICIALLY ISSUED A RECALL BUT SHOULD HAVE SINCE ALL 2011-2013 INFINITI QX56 HAVE CATALYTIC CONVERTER ISSUES THAT NEED TO BE REPLACED. IT IS COVERED IF YOU REPLACE BEFORE 80K MILES BUT IF YOU DO NOT KNOW ABOUT IT COULD COST YOU $6,000. IT IS AN ISSUE WITH ALL OF THEM THAT INFINITI DOES NOT WANT TO ADDRESS BUT SHOULD RECALL AND HELP CUSTOMERS SINCE IT IS AN ERROR THEY MADE IN THESE MODELS WHICH IS NOW FIXED IN NEWER MODELS.

TODAY, I WAS TOLD THAT I HAVE TO REPLACE THE CATALYTIC CONVERTER, WHICH GOING TO COST ME $2,000. I AM THE ORIGINAL CAR OWNER. I RESEARCHED OTHER SITES AND IT APPEARS THERE CATALYTIC CONVERTER ISSUES ON INFINITI 2011 - 2013 QX56 VEHICLES. PLEASE LOOK INTO THESE WEBSITES. THERE SHOULD BE SOME TYPE OF RECALL FOR THESE VEHICLES REGARDING THE CATALYTIC CONVERTER. REFER TO WEBSITES: HTTPS://INFINITIFORUM.NET/INFINITI-FORUM/ARCHIVE/INDEX.PHP/T-13616.HTML HTTPS://REPAIRPAL.COM/TIMING-CHAIN-AND-EXHAUST-STAY-AWAY-FROM-INFINIT-QX56-AND-BETTER-STAY-FROM-ALL-INFINITI-CARS--314 HTTPS://FORUMS.EDMUNDS.COM/DISCUSSION/35247/INFINITI/QX56/2013-QX56-CATALYTIC-CONVERTER-PREMATURE-FAILURE HTTP://REPAIRPAL.COM/ABNORMAL-NOISE-FROM-TIMING-CHAIN-AREA-266 PLEASE CONSIDER A RECALLING THE CATALYTIC CONVERTER ON THESE VEHICLES.

CATALYTIC CONVERTERS HAVE FAILED SEVERAL TIMES. LEFT SIDE CATALYTIC CONVERTER REPLACED BY PREVIOUS OWNER IN 2013. RIGHT SIDE CATALYTIC CONVERTER REPLACED BY CURRENT OWNER IN 2016. LEFT SIDE CATALYTIC CONVERTER NEEDS TO BE REPLACED AGAIN. CONTACTED DEALER AND INFINITI CONSUMER AFFAIRS. THEY DID NOT OFFER A SOLUTION.

IN JUNE 2017, I HAD THE VEHICLE INTO THE DEALERSHIP FOR THE POWER TRAIN RECALL. IN JULY 2017 (87K MILES), I HAD A 420 BANK 1 CAT CODE, AND REPLACED ONE CATALYTIC CONVERTER. IN DECEMBER 2017 (94K MILES), THE 'CHECK ENGINE SOON' LIGHT ILLUMINATED AGAIN, AND THE 430 CODE SHOWS THE OTHER CATALYTIC CONVERTER (BANK 2) NEEDS TO BE REPLACED. IT SEEMS THE CATS ON THESE VEHICLES ARE TERRIBLE, AND ONCE ONE GOES OUT, THE OTHER FAILS TOO. THIS IS VERY EXPENSIVE...ABOUT $2,000 EACH IN MY CASE. THIS SEEMS TOO COMMON BASED ON THE REVIEWS I'VE READ ONLINE NOW. I FEEL LIKE INFINITI SHOULD COVER THE COST OF REPLACING AT LEAST ONE OF THE CATS, BUT I WAS DENIED ASSISTANCE.
