2006 Infiniti QX56 Problems

Abnormal Noise on Acceleration Due to Cracked Exhaust Manifold

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

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.

my dash lights and gauges are intermittently going out. No rhyme or reason when. (1 answer)

Sometimes they all go out and the dash is black and other times some gauges are on like tire warning, engine check, and gear position. I read on line that it might be the IPDM but Infiniti thinks it might be the dash cluster.

2006 Infiniti QX56 Recalls

Engine Stalls Without Warning

A relay in the engine control power distribution module may arc and cause a failure which can result in engine stalling. Dealers will replace the relay inside the module free of charge to resolve the problem.

Nissan-Infiniti Recall for Faulty Front and/or Rear Control Arms

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.

Fuel Gauge Reading May Be Incorrect

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.

2006 Infiniti QX56 Reviews

Rated
based on 2 customer reviews
Lots of QX56 & Armada has 3rd break light problems. Need "RECALL"
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.
