Infiniti QX56 Problems
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.
Infiniti QX56 Questions
Car won't start. All lights, radio, and nav come on. I have a brand new battery. The fusable links look ok (I think). If I press ignition starter while pursuing brake, radio turns off and I hear a vibrating/humming sound
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.
The front brakes make a grinding noise that is not metal on metal when I depress the pedal. It last about as long as it takes to get to the shop and then it stops. A month later, the same thing. ABS braking system problem?

Any fuel leak increases the risk of a fire. Nissan / Infiniti dealers will replace the fuel pressure sensor as necessary to correct this concern.
In the affected vehicles the driver's front airbag may have been manufactured with and incorrect part. This part may block the flow of propellant when the airbag is deployed. This could cause the airbag to rupture, increasing the risk of personal injury. Dealers will replace the driver's front airbag to correct this concern.
On certain vehicles, the fuel pressure sensor may not have been tightened to the correct specification.

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 headl...
My Infiniti QX56 gives me problems when driving over potholes, bumps, uneven roadways -- the steering wheel pulls to the right or just shakes out of my hands. I've taken it to the dealership 3 times for this problem and they cannot seem to figure out what's wrong. They told me that it was b/c I did not have enough air in my tires (first visit)-- WRONG; front end needed aligning (second visit)...
I purchased a 2006 QX56 and loved it; however I had a lot of problems with the vehicle to include a bad transmission, cracked front and rear differential housings, one cracked exhaust manifold and ongoing electrical issues. after talking with the dealer I decided I would upgrade to a 2008 model and just consider the first vehicle a "lemon". The 2008 model I purchased was a little nicer than t...
