 Before you consider buying a qx56 search timing chain issues. Many replaced timing chains and motors because of this issue at or around 70,000 miles. Btw that just happens to be where the warranty runs out. Infiniti is well aware that this is a problem. I've spoken to multiple service dept. luckily my dealer is doing it at cost because they get it. Shame on Infiniti for this kind of service. I'll never own another Infiniti car
