SUSPENSION
While driving my vehicle with my family, I experienced a sudden and dangerous loss of control. I was able to safely maneuver the vehicle off the roadway without injury. After inspection, it was determined that the subframe had fractured due to severe rust, which was not previously identified. The failure occurred without warning and directly impacted the ability to control the vehicle, creating a significant safety hazard. No warnings or messages indicated a problem existed prior to the failure.

ENGINE AND ENGINE COOLING
The contact owns a 2012 Infiniti QX56. The contact stated that while driving at 56 MPH, the vehicle slowed down and failed to respond as intended. An oil change was performed; however, the failure persisted. The contact stated that the high-pressure fuel pump was leaking, causing the timing chain to fail. The check engine warning light illuminated, and the failure progressed, causing the vehicle to stall. The vehicle was not diagnosed or repaired by a dealer or independent mechanic. The vehicle failed on the side of the road and was towed to the residence. The contact used an OBD scanner and retrieved DTC: P0021, P0011, and P0300.

SUSPENSION
While driving at highway speed, rear of vehicle suddenly became uncontrolled and caused vehicle to swerve dangerously. If a vehicle would have been in the adjacent lane an accident would have occurred. Upon initial inspection, the left rear lower control arm failed catastrophically due to rust rendering the vehicle undrivable. Driver and passenger were put at risk as a result of this incident. Deeper inspection revealed the right rear control arm was also compromised due to rust as well as the two forward mounting points of the modular rear suspension cradle (framework). No warning lights appeared, however the steering wheel did begin correcting to the right just prior to event, similar to heavy wind situation. Parts have not been inspected by manufacturer. Pictures attached. Parts are available for inspection upon request.

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 .

ENGINE
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.

ENGINE
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.

POWER TRAIN
A WHINE OR HISS WHEN I START THE VEHICLE AND IT GOES AWAY AFTER ABOUT 10-15 MINUTES. IT WAS DETERMINED TO BE A TIMING CHAIN ISSUE BY MY MECHANIC. THERE APPEARS TO BE A SAFETY RECALL NOTICE FOR THE 2012 QX56, BUT NOT FOR MY SPECIFIC VIN. I DON'T UNDERSTAND HOW THE NHTSA ALLOWS A MANUFACTURER TO ONLY INCLUDE A PORTION OF THE 2012 MODEL AND NOT OTHERS. THIS IS A SAFETY RECALL! DOES SOMEONE AT THE NHTSA RECONCILE THE 2012 QX56 VEHICLES SOLD VERSUS THE VINS ELIGIBLE TO BE COVERED UNDER THIS SAFETY RECALL NOTICE? OBVIOUSLY, OTHERS ARE HAVING THE SAME PROBLEM! I SUGGEST THE NHTSA TAKE SAFETY RECALL NOTICES MORE SERIOUS AND HOLD MANUFACTURERS ACCOUNTABLE!!!

MY WIFE DROVE TO MY DAUGHTERS SCHOOL SCHOOL FOR A BASKETBALL PRACTICE. SHE LOCKED THE DOORS USING THE KEYFOB LIKE ALWAYS. WHEN SHE GOT BACK TO THE CAR SHE UNLOCK THE DOORS USING THE KEYFOB, BUT THIS TIME THE DRIVERS DOOR DID NOT OPEN. SHE TRIED USING THE DOOR ENTRY BUTTON ON THE HANDLE WHICH DID NOT WORK. SHE THEN GOT IN THRU THE PASSENGER DOOR AND TRIED TO PULL THE HANDLE TO OPEN THE DOOR AND THAT DID NOT WORK. FROM THE INSIDE OF THE CAR SHE HAD TO CLIMB OVER THE CENTER CONSOLE TO GET INTO THE DRIVER SEAT. I CHECKED THE OPERATION MYSELF WHEN SHE GOT HOME AND I COULD NOT FIND A WAY TO OPEN THE DOOR. AFTER DOING SOME RESEARCH ON THE INTERNET I FOUND THAT THIS WAS A PROBLEM WITH THE DESIGN OF THE PLASTIC ACTUATOR AND ITS COMPONENT. WITH THE NUMBER OF PEOPLE HAVING THIS PROBLEM, I AM SURPRISED THERE ISN'T A RECALL SIMILAR TO THE TAKATA AIRBAGS SINCE THIS WOULD NO PASS AN INSPECTION AND WOULD BE A HAZARD IN THE CASE OF AN ACCIDENT
