Infiniti QX56 Problems
The Rear Power Door May Not Open or Close Properly
The rear power door may not open or close properly, or make a grinding noise from inside the rear trim panel. If this occurs our technicians recommend to check for loose or damaged hardware at the rear door motor. Replace damaged hardware as required and use bolt retaining compound when reassembling the door motor hardware.
The Fuel Gauge May Read Incorrectly
The fuel gauge may be slow to register, fail to read full when the gas tank is actually full, or read inaccurately. Our technicians tell us there is a redesigned fuel tank sender unit to remedy this problem.
The Airbag (SRS) Light May Illuminate With Code B1177 and/or B1182
The airbag (SRS) light may illuminate with code B1177 and/or B1182, related to the front seat belt pre-tensioners. Our technicians tell us revised front seat belt buckles are available to correct this concern.
A Clunking or Popping Noise May Develop From the Front Suspension
A clunking or popping noise may develop when driving over pot holes or rough roads, the front coil springs may be the source of the noise. Our technicians tell us updated parts are available to address this problem.
The Check Engine Light May Illuminate With Controller Area Network (CAN) Fault Codes Stored
The Check Engine Light may illuminate with controller area network (CAN) fault codes stored. Our technicians tell us that cleaning the electrical ground connections around the powertrain control module (PCM) to allow better electrical conductivity should help with this concern.

Infiniti QX56 Stories
I purchased a 2006 QX56 and loved it; however I had a lot of problems with the vehicle to include a bad transmission, cracked front and rear differential housings, one cracked exhaust manifold and ongoing electrical issues. after talking with the dealer I decided I would upgrade to a 2008 model and just consider the first vehicle a "lemon". The 2008 model I purchased was a little nicer than the 2005, with better technology and for the most part it has been a much better vehicle from a repair standpoint. The main problem that remained was the cracked exhaust manifold; BOTH sides cracked about 12,000 after the warranty ran out. When I was told what the problem was causing the "noise" I asked "isn't this unusual" and the answer from the service agent and the mechanic was "no, this happens to all the QX's; the manifolds are made out of stainless steel and the heating and cooling causes them to crack!" Then I asked why this would not be considered a manufacturer's problem and I was told "it just isn't; you are out of warranty and its YOUR problem!" they wanted $2,800 to fix the two manifolds, which I declined. Instead I decided that I would ask Infiniti WHY THEY ARE NOT FIXING an OBVIOUS DEFECT? How can they expect to keep customers loyal to their brand if they are not going to back up their product? I LOVE THIS VEHICLE but if Infiniti is not going to back up their product, then I will never buy another one and I will make it my mission in life to take away as many future customers as possible. I recommend you buy this vehicle IF you can talk your dealer into GIVEING you an extended warranty that exceeds 100,000 miles
I love my QX56 after five with no problems at all, until now. My dash panel lights went out. They come on when i put light switch on auto or turn the head lights off.I need help ,what is the problem with my dash panel.
Brought a 2007 Infiniti QX56 in 2010. It's a beautiful looking vehichle, inside and out. I'm new to the brand and heard great things about Infiniti but I'm still waiting to be impressed. Now my warranty is run out, things are starting to go wrong.
I have a 2005 I bought new. It now has 98,000 miles. We have pulled a 32 foot travel trailer up to NY state and down to Florida multiple times. It has been a very good vehicle and we are very happy with it. The only significant problems we had were cracked exhaust manifolds and front brake warping, which were all fixed under warranty and improved or corrected on later model years. Despite the abuse three kids, two dogs, and no garage can inflict, it still looks new inside and out. It burns no oil between 7,500 mile changes. I have always used Mobil 1 5w30. Gas mileage is not great but it will get 20 mpg on the highway without the trailer. My soon to be teen drivers argue over who will get to drive it, they still love it.
Likely the best truck frame vehicle that I've owned. It has impressive pick up and a comfortable ride. The only issue I have noticed is that the front end "feels" like it is hopping a tiny bit when crossing expansion joints on bridges or uneven road surfaces. The interior and amenities are first class.
