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.

Takata inflators the vehicle was running on the highway and even after accelerating it won't run enough to get past traffic while changing lane and causing severely dangerous situations.

I have issues with air compressor and timing chain that just randomly went out, I was told there was a recall or campaign for it with Infiniti I called Infiniti and sent it to the dealership they stated it was not for my actual VIN number but for same car with different VIN number, I asked the question since I am having the same issue that has a recall on another VIN same vehicle shouldn't your company fix all of that year vehicles make and model. I was told no.

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.

Engine light came on dealer states that I need new catalytic converter on my front driver side.

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.

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.

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. . Read more...
