2012 Infiniti QX56

The contact owns a 2012 Infiniti QX56. The contact stated while driving 30 MPH and depressing the accelerator pedal, the vehicle started shaking violently. The contact stated that the check engine warning light was illuminated. The contact took the vehicle to the local dealer, where it was diagnosed with needing the timing chain to be replaced. The vehicle was not repaired and continued to experience the failure. The manufacturer had been informed of the failure. The failure mileage was approximately 87,000.

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
