Infiniti QX56 Abnormal Noise From Timing Chain Area
Infiniti QX56 Problem
Visitor, 2011 Infiniti QX56, 90,000 mi
My car was making a high pitched winding sound on start up and wouldn't stop. Now having to replace timing chain at a cost of $3000!! Bought it used only 9 months ago and have had to repair both catalytic converters, air sensory intake and now this...... very concerned with the quality of this car with all these issues......looking at trading it in over the next year or so...... first Infiniti I have ever purchased and love the ride, look of the car but not so much regarding mechanical end of it. Looking to see if others have had issues same or different than me.
