2007 Infiniti QX56 Problems
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.
A clunking or popping noise may develop when driving over pot holes or rough roads, the front coil springs may be the source of the noise. Our technicians tell us updated parts are available to address this problem.

RepairPal Expert Overview:
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.

2007 Infiniti QX56 Questions and Answers
2007 Infiniti QX56 Reviews
There was condensation in the front headlight casing, which started forming shortly after I purchased the used car. Over time the condensation built up and caused headlight failure. I brought to a local auto body shop and they could not find any cracks in the casing. When they called an Infiniti parts dealer, the dealer let it be known that it was a design defect and that they keep the headlight casings in stock. $1,500 later I was told by Infiniti that they have no responsibility and could not do anything for me. I will never buy another Infiniti. My only recourse now is to file a complaint with the National Highway Traffic Safety association and hope that they issue a recall.
