2007 Infiniti QX56 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2007 Infiniti QX56

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.

I'm dealing with the truck swaying left and right when hitting small bumps like man hole covers and uneven road surface, you almost feel as if your going to lose control of the vehicle. The truck is a 2007 Infiniti QX56 4wd and just hit 100k miles. It seems a lot of people are experiencing si...

blowing a lot of smoke when I start the car, Infiniti claims that since I never had the oil changed that the whole engine needs to be replaced. The car runs great except for the smoke coming out the back when started.

Nissan is recalling certain 2004 - 2010 Titan, Armada, & QX56 vehicles. Also included are 2005 - 2010 Frontier, Xterra, and Pathfinder vehicles for faulty front and/or rear suspension lower control arms. The problem is the control arm's attaching point to the vehicle's chassis. During the manufacturing process, some control arms may contain welds that do not meet Nissan's strength specs, and if they break, it may result in loss of vehicle control, and a possible crash.

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.
