I love this vehicle but it's suddenly started having a rough idle and with a scan tool detects multiple misfires and several codes due to timing, in which case the timing chain has been worn out call the dealership to see if the timing chain recall for the m56 was done to my car they said it was VIN specific now I am stuck with a vehicle that is very dangerous to be driven.Owner report · Engine · Oct 2021
Here is a copy of a blog. I have bought 6 battery's in 4 years. I have been stranded with the family late at night paid for many tow trucks. Taken my car to infinity dealers with no success. Please read this blog.. Https://x.infinitihelp.com/forum/showthread.php/2011-m37x-battery-problemsi-7942.html 4 pages of peolple having the same issue with there infiniti. I am told I have to pay for a 1200 module that maybe will fix the problem. This is not a problem that anyone would notice in the first couple of years because you think the battery is at fault. Infiniti fix the issue in 2014 but did not do a recall on prior m37/56.Owner report · Unknown Or Other · Feb 2019

I started the car up and started to drive to work about 3 miles into driving the check engine light came on followed by revs with no power or speed gain and the vehicle was giving me around 15mph to the point where I couldn't gain much more speed and had to pull off the road. There was a voluntary service campaign for the timing chain but it has since expired and now I am stuck with the repairs.Owner report · Engine · Feb 2019
Driving this car is very fun and I have enjoyed the car very much but just last week I noticed a smell like burning rubber or oil, come to find out the next day I was dripping oil only not a steady drip but a drip only from driving, once I stop and the car cools the drip stops. I have research and found that there could be a problem with some bolts to the oil filter that attaches to the block but when I called infiniti they don't see it nor will they look at the car unless I pay. This isn't a seal or gasket this is a very bad leak, my research came from a 2012 long term road test on a 2011 infiniti m56 and states this will become a recall but never did? *trOwner report · Engine · Apr 2015
