Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #11181548, filed 2019-02, 84,000 miles“My solenoid switch went bad on me and needed to be replaced, took it to the Infiniti dealership and they corrected the problem so I thought until oct 13 when I kept hearing this noise coming from my hook like a squealing noise.. Took it back to the dealership and found out it was the timing chain, which I was told had nothing to do with the solenoid switch that was previously fixed.. …”
NHTSA complaint #10645053, filed 2014-10, 87,000 miles“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. …”
NHTSA complaint #10704818, filed 2015-04, 141,000 miles“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.”
