Infiniti QX56 Problems

Exhaust & Emissions -- Verified

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.

Miscellaneous -- Verified

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.

Electrical & Lights -- Verified

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.

Suspension & Steering -- Verified

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.

Miscellaneous -- Verified

The airbag (SRS) light may illuminate with code B1177 and/or B1182, related to the front seat belt pre-tensioners. Our technicians tell us revised front seat belt buckles are available to correct this concern.

Infiniti QX56 Reviews

Mine required new struts. I believe the biggest noise maker and general slop inducer was worn out sleeves that go onto the top of the strut rod. Before replacing the struts and these small, round sleeves/bearings that the tops of the struts go through, I had a lot of noise and generally goofy action in the front end when going through potholes and uneven/rippled pavement. $900 fix, but it did fix it. My truck had 95k miles on it at the time of repair.

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.

3rd break light not working. its 2nd repair. They designed break light with rear washer on one part. Nonsense...

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

I have a 2005 QX56 which I bought brand new and the only major problems I had was the lift gate motor went out after my 6 year of having. It was covered by my extended warranty. I had to replace both headlights and fog lights at seperate times because the seals had warn and they were getting condensation inside of them which was covered under warranty at time also. My AC went out under the extended warranty and it took them almost 60 days to replace part because it had to come from Japan. Some type of regulator that they had to remove the front dash to get too. Other than that the vehicle has been great.
