Check engine light came on so I took it to an autozone to have the code read. Po463, fuel sending unit. Did some research, called Nissan corporate to inform them of the issue and see if I was eligible for extended warranty (wasn't covered). Nissan corporate informed me that I was eligible for ecm relay replacement at no cost at a dealership, so I took the car to a dealership that quoted me lowest on the fuel sensor repair. They asked if I had other issues and I told them that my engine sometimes sounded like an rc car. They offered to look into it, called this afternoon after completing work on sensor and ecm relay to inform me that my timing chains were shot and in need of immediate replacement. Did some more research and found this is a frequent issue in Nissan cars, decided to file a report.
Check engine light came on and stayed on. Had diagnostics and found catalytic converter not to be working properly. Replaced catalytic converter on 29 Nov 2012. Again on may 2013 check engine light came back on and again it was the catalytic converter. Had to have it replaced again. Total cost of both replacements was in excess of $1900. 00. Contacted Nissan and they would not stand behind their product, said that warranty had expired. Had converter replaced at Nissan dealer the first time.
