general problems of the 2011 Infiniti QX56

Unknown. Timing chain issue. When car is started it makes a noise for about 10 min then goes away.

Catalytic converter, a/f sensor failed on the interstate when I was driving with kids in the car. Took vehicle to the nearest dealer only to be told that this is a known problem with these vehicles and it was going to cost me $3,100 to repair.

I'm currently dealing with the timing chain nightmare so many others have had and are having. Of course just as most of the others I'm out of warranty and really frustrated that Infiniti hasn't stepped up to the plate to address the problem properly as opposed to renaming the Qx56 to qx 80 to save themselves, leaving consumers scrambling with expensive time consuming fixes to a known defect on their part. Where's the accountability on their part, do a certain number of people have to die or be injured before the consumers are provided with the proper assistance? who really looks out for us? a recall was done in 2016 obviously they need to expand the VIN number.

On June 1st 2020 I took my 2011 Infiniti Qx56 to the shop for having the code p0087. The shop told me that I should take it to the dealership because the problems the vehicle is having are recalled under voluntary safety recall campaign. When I called my local Infiniti dealership they told me my VIN # doesn't doesn't show as recalled. They dealership provided me with the phone number of Infiniti consumer affairs. I called Infiniti affairs and told them about my vehicle they told me that they were sorry but my VIN doesn't show up on their system. The bottom line is that every single thing that I researched and find the wrong of the vehicle comes back with a voluntary recall. Like the fuel system, timing chain, vvt solenoids, high pressure fuel pump. I use vehicle in the city and highway.

My vehicle needs two catalytic converters replaced in order to pass smog. Infiniti dealer wants $5600 to make this repair! this is a common problem for this vehicle and should be a recall item.

Catalytic converters have failed several times. Left side catalytic converter replaced by previous owner in 2013. Right side catalytic converter replaced by current owner in 2016. Left side catalytic converter needs to be replaced again. Contacted dealer and Infiniti consumer affairs. They did not offer a solution.

We purchased this vehicle used on may 5, 2017. My wife was driving it down a city street at less than 45mph, and it broke down on us on may 23rd, and was sent in for repairs. Told it was a relay or an issue with the timing. Got the vehicle back on June 1, and here it is June 7th and at the same location as before, at the same speed, it broke down with the same issue. We've owned the vehicle for one month and been in the shop twice. Please help as this has the potential to be a very costly repair.

Timing chain failed, needed to be replaced, $6000+ repair.

With 72000 miles on the vehicle, two thousand over warranty, the timing chain has to be replaced. Infiniti refuses to offer any financial assistance when it is an obvious manufacturing defect. That is evidenced by the fact that replacement parts have been completely re-engineered. A timing chain failure at highway speed would result in a serious accident or fatality. The vehicle has been carefully maintained by Nissan.
