    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.

    I have been having the issue for a while, (very noisy at start up) then it would smooth out after about 10 minutes. I thought it was the cooling fan or something else. I got in yesterday morning and no Power, irregular idle, then it smoothed out. Took it directly to the dealer, thought maybe bad gas. Called me today 100% sure its the timing chain....a known issue with this vehicle. $4000 repair. We maintain the vehicle, and actually had even tried to extend the warranty, but they were no very good at following up on that? Anyway I have called the consumer affairs folks for some help and hope they do the right least from my perspective. This is by far the most expensive vehicle I have ever purchased by 2x and certainly would not have expected this type of an issues at such low mileage. I have 300K on my 2002 suburban and never had a repair over 4th child is still driving it!

    Car makes whistling noise upon start-up, which goes away after about 10 minutes. Finally, the car stalled and needed to be towed in to the dealer on a flat bed truck. Originally, the dealer said it needed a new engine, but after further review they blamed it on a faulty timing chain.....with a repair quote of between $4000 - 5000. This car is only 2 years old!!! I smell a recall. Too many people with the SAME EXACT PROBLEM>

    Hissing noise coming from the engine block very early in the morning or when the engine is very very cold. If allowed to warm up for about 10 minutes it drives just fine. Dealership says its a timing chain issue that needs to be replace. Total cost is about $4600.00. Never hear of that. Don't understand how that can happen in a relatively new car.

    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.

    Just outside of warranty and it's a $3700 repair. I went to Infiniti in attempt for assistance on the repair and was denied as they said I was really far outside of warranty. 6k miles seems to be a little extreme for Infiniti. I'm not sure they believe in the product they are selling. It was a week to complete the repair. It seems to be an ongoing problem.
