The SUV was driving without issue; however, if the timing chain had broken we would have had an engine stall which could have caused an accident. We heard a noise in the car and decided to be safe and take it in for service. After getting to the Infiniti dealership of gwinnett the noise had subsided. We explained we heard a whining noise when the car was starting up that went away after a time. The noise wasn't even evident but they knew what it was before even hearing it. After letting the car cool down they started the engine up again and heard the noise. They let us know this had confirmed the initial diagnosis of a timing chain issue. After getting home and looking up the issue with the car I was surprised to see so many people talking about this issue. Apparently Infiniti has a defective oil pump that lubricates the chains that caused this issue. I wanted to voice my concern and displeasure with the timing chain issue that appears to be a common issue with the 2011 Qx56.
