2006 Infiniti QX56 Repair and Maintenance

A guide to problems, costs, maintenance and repair for your 2006 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.

The display only works when I place the car in reverse, I can see with the backup camera. I cannot see anything on it, no radio (works) no climate control (works also). The screen looks illuminated and you can kinda see a "ghost image" on it, but it is not bright enough to really do a...

Sometimes the gps screen/radio/tv work. But, when it's not, the screen stays illuminated (blank screen), even with car turned all the way off (keys out of ignition). Ultimately draining the battery. Is this an electronic short or does it need a new fuse?

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.

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.

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.

Lots of QX56 & Armada has 3rd break light problems. Need "RECALL"
