After four years of owning this vehicle purchased new, the passenger side seatbelt warning light came on the dash. It indicated the seatbelt was not buckled while no one was sitting in the passenger seat. When buckled the light went out. Brought it to the attention of Nissan, Service every year when they would clear the code and it would be good for a month or two, and the light would come back on like before. Last month on May 9, I brought the vehicle in again and asked for a thorough assessment. Nissan service said to make the light go out they would have to replace two passenger side occupancy sensors, totaling $1800 parts and labor. They did not have the parts on hand, I left with the vehicle only to find out that the intermittent seatbelt light that would go out when buckled, stayed on continuous now. Also noticed the illuminated airbag light stating the airbag was off. And that was also on at all times whether someone was in the passenger seat or not. When purchasing the vehicle new we also purchased a gold preferred extended warranty, that I believed would cover these parts. But Nissan, consumer affair said the the warranty will not cover those items. After a month of trying to get Nissan, service and consumer affairs to work with me, still no help. Searching online I found Nissan, has had numerous issues and even some recalls with occupancy sensors in the seats of many vehicles. It seems to be an ongoing issue with Nissan, regarding earlier model vehicles and newer models. Thank you for your time and your help.
