Was driving my vehicle and first noticed a drop in fuel economy. Later it was losing power and stalling. Gave me p0090 and p0087 codes. Happened in both driving and stationary positions. Turns out my high pressure fuel pump is bad.

Infiniti/nissan issued a recall back in 2010 (recall id#10v074000) for fuel gauge/sensor sending unit problem. The same issue is happening on later year vehicles, but no recall has been issued. There are endless reports on the web across many forums where people are having the same problem for something that has been recalled before. See notes from past recall. Recall id # 10v074000 - fuel system, other:storage:fuel gauge system recall date: mar 03, 2010 summary: nissan is recalling certain model year 2005-2009 titan, armada, and infiniti qx56 vehicles. The instrument panel fuel gauge may inaccurately display that the vehicle still has some fuel, typically about one quarter tank, when the fuel tank is empty. Consequence: this could cause the vehicle to run out of gas and stall on the highway, which could cause a crash. Is this no longer a safety concern? Same issue, just later models... Mine specifically is a 2011 and I never know how much gas is in it. It fluctuates and shows empty when it's not and shows full when it's not. Please investigate and advise the many owners that are having this problem.

The SUV was driving without issue; however, if the timing chain had broken we would have had an engine stall which could have caused an accident. We heard a noise in the car and decided to be safe and take it in for service. After getting to the infiniti dealership of gwinnett the noise had subsided. We explained we heard a whining noise when the car was starting up that went away after a time. The noise wasn't even evident but they knew what it was before even hearing it. After letting the car cool down they started the engine up again and heard the noise. They let us know this had confirmed the initial diagnosis of a timing chain issue. After getting home and looking up the issue with the car I was surprised to see so many people talking about this issue. Apparently infiniti has a defective oil pump that lubricates the chains that caused this issue. I wanted to voice my concern and displeasure with the timing chain issue that appears to be a common issue with the 2011 qx56.

Through my research and speaking with infiniti mechanics there has been a known issue with timing chains and associate parts that are a hazard and a major expense to 2011-2012 infinity qx56 owners. This issue will leave you stranded somewhere!! It happens to my wife and I three times!!! I had to get it towed all three times!! The hazard is while driving on highway the engine just loses all power leaving the hazard of someone running in back of you. If you driving up an incline and this problem comes about your vehicle will stall an you can possibly start rolling backwards. So from my research this problem has been happening to people either right before there warranty ends at 70,000 miles or right after (like me) at 74,000 miles. I called infiniti and they refused to help me in any way. The guys at my dealership said its a hit or miss with them helping owners of the qx56 that's over the warranty. I was already $1500 in the whole on parts they thought were the problem and now they want to charge me an estimated $3,000-4,5000 to do the rest of the work. Its a fact that infiniti knows they have this issue and refuses to recall or help the owners. I will never purchase a infiniti again!!! And will spread the word around about them!
