I purchased a 2006 Nissan Xterra with 36k miles. May 15th, 2009. I currently have 112k miles on it and have a not start a/t cont fuse blown issue. My service engine soon light came on and took it to my mechanic who told me there was a code stating a speed differential between the front and rear of the transmission. Soon after further inspection, my mechanic verified radiator fluid leaked into the transmission and I will need to replace both my radiator and transmission to the approx cost of $5500. Needless to say, not only is the extended warranty expired, but I will have to pay the full amount of the repair out of pocket since the lawsuit filed against Nissan concerning this issue expired in 2013. Buyer beware!!! be careful if you purchase a Nissan Xterra from 2005-2010 unless you are prepared to fork out more money than expected to pay for a defect that Nissan knew about but will no longer support.
