“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 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? *tr”Owner report · Engine · Apr 2015
