I got Code : P0011 (my mechanic said that timing chain has to be replaced) I saw that Infiniti run the campaign as below : Dated July 15, 2016 VOLUNTARY SERVICE CAMPAIGN 2011 – 2013 QX56 AND M56; TIMING CHAIN CAMPAIGN ID #: P6305 APPLIED VEHICLES: 2011-2013 QX56 (Z62) 2011-2013 M56 (Y51) Check Service Comm to confirm campaign eligibility 2011-2013 QX56 IMPORTANT: The following service procedure for 2011-2013 QX56 is an abbreviated version of the Electronic Service Manual (ESM) procedure to replace the timing chains and related components. The Claims Information is based on this abbreviated procedure. I called Infiniti and they said that this campaign was for limited time and we called you but i never heard or aware about this otherwise I would have got it done . I have all the service record serviced everything from Infiniti dealer and the best maintanace Apart from that I get below code also which is makes me to think I did mistake buying Infiniti. P0300 P0011 C1118 C1130 C1A26 C1A14 C1a04 Buying car with full upgrade, waste of 98K .

The contact owns a 2012 Infiniti QX56. The contact stated that while driving at high speeds, the vehicle shook and then lost motive power. The vehicle was towed to the dealer and diagnosed with fuel pump failure. The dealer informed the contact that the fuel pump needed to be replaced. The vehicle was then towed to an independent mechanic and diagnosed with timing chain failure. The independent mechanic informed the contact that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was unknown.

I own a 2012 QX56. Check engine light comes on and I take it to the dealer. It's the Catalyst System Efficiency Below Threshold (catalytic covers - P0430 code) I was warned before I bought this vehicle about the cats going bad. Infiniti dealer, that I purchased the truck from said "this vehicle has been serviced at an Infiniti dealer since day one. Every possible service that was needed was completed. The owner took immaculate car of this truck. You won't have any issues." So tell me, if this vehicle was driven exactly how it was supposed to be and yet at 113K miles the cats go bad, why isn't there a recall?? This is a "top of the line SUV" and yet it needs $4500.00+ in engine repairs at just over 113K miles. Infiniti needs to step up and take responsibility for this issue. If dealerships are warning you about this issue, obviously there is a KNOWN issue.

My 2012 Infiniti QX56 has a loud rattling noise coming from the engine. This started around Oct 2020 and comes and go. It has got worse over the last month or so and has started stalling and acting like it doesn't want to go. A few times the car will start shaking while I'm driving. It has been checked out and codes for converter and timing chain are there. Engine light is on. I drive this car with my 2 children and am afraid of the safety issue. I know there is numerous others having these same 2 issues with my year and make of car. Spoke with Infiniti Corp. and they will not do anything about it because my VIN is not under the recall. However, the vehicles with this issue that have been repaired under the recall have the same engine and same issues that I'm having. I think all vehicles in 2012 regardless of VIN should be under the recall as I'm seeing so many with these issues.

HAD NO PRIOR ISSUES, DRIVING DOWN THE HWYAT 65 MILES PER HR.. CAR FAILED. COSTED TO SIDE OF ROAD MADE IT TO REPAIR SHOP AND THE FUEL PUMP WENT OUT, WHICH AFFECTED THE TIMMING CHAIN AND BROKE THE TEETH, WHICH HAS AFFECTED THE MOTOR. THIS IS A DESIGN DEFECT THAT HUNDRED OTHER FOLKS ARE HAVING. I COULD HAVE LOST MY LIFE WITH THIS VEHICLE

AT 82,000 MILES THE CHECK ENGINE LIGHT CAME ON INDICATING BOTH CATALYTIC CONVERTERS WERE BAD. THEY ARE WARRANTIED TO 80K MILES AND OF COURSE MANUFACTURER WOULD NOT HELP. THIS NEEDS A RECALL, GOOGLE QX56 CATALYTIC CONVERTER AND SEE HOW MANY PEOPLE HAVE HAD THIS ISSUE.

I AM EXPERIENCING THE SAME ISSUES THAT HAVE BEEN POSTED BY SEVERAL OTHERS ON THIS SITE WITH THE CATALYTIC CONVERTER AND THE BATTERY (JN8AZ2NE3C9****, JN8AZ2NF1C9****, AND JN8AZ2NC9C9****). I TOOK IT TO GET CHECKED OUT YESTERDAY AND JUST RECEIVED A CALL FROM THE TECHNICIAN. HE STATED THAT BOTH CATALYTIC CONVERTERS HAVE TO BE REPLACED AND IT WILL COST $5,200. IF THIS IS A COMMON ISSUE, WHY IS INFINITI NOT RECALLING THIS AS AN ISSUE? INSTEAD IT APPEARS THAT THEY ARE MAKING CONSUMERS PAY FOR MECHANICAL PROBLEMS THAT THEY ARE CLEARLY AWARE ARE MANUFACTURING PROBLEMS. I HAVE ALSO HAD TO CALL MY INSURANCE COMPANY TO TOW MY VEHICLE BECAUSE THE BATTERY WAS BEING COMPLETELY DRAINED. IT WAS TOWED TO INFINITI AFTER A FEW INCIDENTS BUT OF COURSE THEY COULD NOT TELL ME WHY I HAD TO KEEP BUYING BATTERIES FOR THE VEHICLE. IF INFINITI FAILS TO ACKNOWLEDGE THESE ISSUES, I WILL NO LONGER PURCHASE THEIR VEHICLES. THIS IS OUTRAGEOUS AND IRRESPONSIBLE.

EXPERIENCING ALMOST IDENTICAL ISSUES TO ANOTHER COMPLAINT I SAW THAT WAS PREVIOUSLY FILED (#10924936). TOLD WE NEED TO REPLACE CATALYTIC CONVERTERS AT $2,000 EACH. DEALERSHIP SAID IT'S A KNOWN ISSUE WITH THE VEHICLES. IF IT'S A KNOWN ISSUE, PERHAPS SOMETHING SHOULD BE DONE ABOUT IT. WE'VE ALSO HAD TO HAVE THE BATTERY REPLACED NUMEROUS TIMES. HAD TO CALL AAA SEVERAL TIMES TO JUMP THE VEHICLE.

Mileage: 107,506

WE HAVE HAD PROBLEMS WITH THE BATTERY SINCE WE BOUGHT THE QX56. SUV'S COMPLETELY DIES AFTER A GLOVE BOX LIGHT, RADIO HAS BEEN PLAYED FOR 20 TO 30 MINUTES, CAR CANNOT BE JUMPED BY TYPICAL CABLES, EVERY TIME WE EITHER HAD TO HAVE A HEAVY DUTY JUMP DONE BY TOW COMPANY OR BATTERY WAS REPLACED BY INFINITI. TIMING CHAIN AND BOTH CATALYTIC CONVERTERS NEED TO BE REPLACED, WITH ENGINE ISSUES. INFINITI HAD SUV FOR ALMOST A MONTH TO FIX ENGINE AND TIMING CHAIN. ENGINE LIGHT STILL COMING ON THEN WE WHERE TOLD THE CONVERTERS NEEDED TO BE REPLACED. $5K TO FIX. IT SOUNDS LIKE THIS IS A VERY COMMON ISSUE WITH QX56 FOR THIS YEAR AND OTHERS. AFTER EACH TIME ENGINE LIGHT CAME ON INFINITI SERVICE DEPT TOLD US TO CONTINUE DRIVING THE CAR AND AFTER 2 WEEKS IF IT DIDN'T RESET THEN CALL BACK AGAIN. WE DID THIS RELUCTANTLY, BECAUSE I AM MY WIFE HAVE BEEN TAUGHT THAT WHEN YOU HAVE AN ENGINE LIGHT COME ON, STOP CALL, AND GET THE VEHICLE IN TO BE INSPECTED.

INFINITI QX56 HAS A UBIQUITOUS ISSUE WITH TIMING CHAIN FAILURES GOING OUT BETWEEN 60K-80K MILES. THIS PROBLEM IS NOT ONLY A VERY EXPENSIVE REPAIR ($3K TO $5K), BUT IS ALSO A SEVERE SAFETY ISSUE IF TIMING CHAIN WERE TO FAIL ON THE ROADWAY. INFINITI HAS MENTIONED A POSSIBLE RECALL, BUT SEEMS TO STALLING DUE TO THE MASSIVE EXPENSE THAT THEY WOULD HAVE TO BARE. I DETECTED A PROBLEM AT APPROXIMATELY 70K MILES, WHEN STARTING ON COLD MORNINGS. MY VEHICLE SOUNDED LIKE A SCREAMING EAGLE FOR THE FIRST 5 MINUTES OF OPERATION. I EVENTUALLY HAD A FAILURE JUST OVER 80K MILES (FORTUNATELY, WHILE IN THE DRIVEWAY). PER THE SERVICE MANAGER AT MY LOCAL INFINITI DEALER, THEY HAVE KNOWN ABOUT THE PART DEFECT WHICH ALL TOO COMMON ON 2010-2012 QX56 MODELS. INFINITI RESOLVED THE ISSUE AND DEVISED A NEW TIMING CHAIN FOR THE 2013 MODEL. I HAVE ATTACHED A COPY OF MY REPAIR BILL, ALONG WITH THE SAME DIAGNOSIS OF MANY VEHICLES FROM THE REPAIRPAL WEBSITE. I WOULD APPRECIATE ANY THING YOU COULD DO ON MY BEHALF AND THE THOUSANDS OF OTHER CUSTOMERS WHO HAVE SUFFERED THE SAME FATE.

THE INFINITI QX56 HAS A KNOWN ISSUE WITH THE TIMING CHAIN ON THE SIDE THAT DRIVES THE FUEL PUMP. THE CHAIN STRETCHES AND BEGINS TO RUB METAL AGAINST METAL. THE COST TO REPAIR IS 4000 - 5000 DOLLARS AND IF YOU DO NOT REPAIR YOU RUN THE RISK OF RUINING THE MOTOR AND THAT IS 17,000. I WAS TOLD BY THE INFINITI MECHANIC IT IS A KNOWN ISSUE AND HE COULD REPAIR THEM IN HIS SLEEP AND THE NEW CHAINS ARE "HEAVER DUTY". INFINITI SAYS IT IS NOT A COMMON PROBLEM SO THEY WILL NOT REPAIR IT OUT OF WARRANTY. SEE THE ATTACHED WEB SITE. JUST THIS ONE SITE HAS OVER 70 PEOPLE WITH THIS ISSUE. HTTP://REPAIRPAL.COM/ABNORMAL-NOISE-FROM-TIMING-CHAIN-AREA-266 AT 4000 TO 5000 TO FIX THAT IS ALMOST 400000 IN REPAIRS FROM JUST THIS ONE SITE. IF IT IS NOT AN ISSUE I WONDER WHY THE NEW TIMING CHAINS ARE HEAVIER. THESE ARE NOT CHEAP VEHICLES AND INFINITI SHOULD STAND BEHIND THEIR PRODUCT. IF THEY WILL REPLACE IT UNDER WARRANTY THEN IT IS NOT NORMAL WEAR. I COULD NOT GET INFINITI TO TELL ME HOW MANY TIMING CHAINS THEY HAVE SOLD AND / OR HOW MANY REPAIRS HAVE BEEN DONE ACROSS THE US BOTH IN AND OUT OF WARRANTY, MAYBE THEY WILL RESPOND TO YOU. IF YOU GOOGLE INFINITI QX 56 TIMING CHAIN ISSUE, YOU WILL SEE IT IS NOT AN ISOLATED EVENT.

INFINITI QX56 2012 WITH 100,000 MILES STARTED MAKING WHINING NOISE AT START-UP AND THE ENGINE WOULD RUN AND SPUTTER WITHIN 7K MILES OF A FULL SYNTHETIC OIL CHANGE. CALLED DEALERSHIP AFTER WORKING WITH LOCAL MECHANIC AND THEY KNOW THEIR IS A BULLETIN ON THIS VEHICLE THAT REQUIRES AND NEW TIMING CHAIN BE INSTALLED. SEEMS THIS IS ALMOST A 100% FAIL RATE AND JUST IS A MATTER WHEN VERSUS IF THIS WILL FAIL. SPEAKING TO INFINITI AND NISSAN THEY WILL NOT COVER ONE DIME OF THIS $4,500 REPAIR EVEN THOUGH THIS IS A MANUFACTURING LATENT DEFECT. I SPOKE TO TWO DEALERSHIPS AND THEY DO BETWEEN 30-40 OF THESE $4,500 REPAIRS A MONTH...THIS IS SIMPLY CRIMINAL THAT THERE IS NOT A RECALL ON THIS ISSUE. THIS IS A HIGH LUXURY VEHICLE AND TO HAVE THIS ISSUE IS A CRIME. THANKS.
