It is not uncommon one or both of the exhaust manifolds to crack resulting in an exhaust leak. Symptoms will begin as a ticking type noise noted on acceleration when the engine is cold.

2005 Infiniti QX56 Problems
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 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.
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 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.

RepairPal Expert Overview:
The instrument panel fuel gauge may show fuel in the fuel tank when there is none, typically about 1/4 when the tank is empty. This could cause the vehicle to run out of gas and stall, increasing the risk of a crash. Dealers will replace the fuel sender unit inside the fuel tank to correct this concern. This recall is expected to begin on March 22, 2010.
RepairPal Expert Overview:
The AC condenser fan motor in the engine compartment may not be sealed properly against water intrusion and it may not have proper drainage. Water intrusion may lead to corrosion and possibly overheating of the motor, and a fire. Dealers will install a "thermal protector kit" and test and replace the AC condenser fan motor if needed. The recall began August 2, 2008.

2005 Infiniti QX56 Reviews
I have a 2005 QX56 which I bought brand new and the only major problems I had was the lift gate motor went out after my 6 year of having. It was covered by my extended warranty. I had to replace both headlights and fog lights at seperate times because the seals had warn and they were getting condensation inside of them which was covered under warranty at time also. My AC went out under the extended warranty and it took them almost 60 days to replace part because it had to come from Japan. Some type of regulator that they had to remove the front dash to get too. Other than that the vehicle has been great.
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.
