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.
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.

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.
