2007 Infiniti QX56 ProblemsExhaust manifolds crack and make loud noise on acceleration
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 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 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.

2007 Infiniti QX56 RecallsNissan-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.
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.
