My QX60 has 4000 miles on it, purchased on December 28, 2013. It has intermittent problems with the backup camera. Of the four cameras, the back camera, is the only one with this problem. It starts to dim, get fuzzy, starts shaking, then grays out completely with lines that seem like static lines. I took videos with my phone and sent them to my service advisor, but he said that Inifiniti has to see the problem in action. Today I took it back in, and actually got it to reproduce the problem. The head technician from that department came out and said he had never seen this before. They kept the car and said they will have to send the problem through their technical support to try and diagnose the problem. Has anyone seen this? He mentioned that it could be the camera itself, or a screen problem. He sat in the car and ran a diagnostic tool on monitor, and it didn't show any errors. They told me they would have to keep it a few days.
