    Loud noise coming from the front end of my 2011 QX56. Report from dealer is issue with timing chain.
    Solution. . . Replace engine at a cost of 16k. I don't understand how the Infiniti
    people can sell a SUV for what this one cost and have the engine go out at 105,000 miles.
    Crazy!! Told me they could give me a good deal on a trade-In. Yeah, Right!!

    Not sure what to do. Seems like there should be other options.

    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.
