2005 Infiniti QX56 Problems

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.

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.

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.

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.

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.
