After having rear ends fail all through my warranty period and the last differential still under the 12000 mile part warranty, Nissan has refused to fix it. The general Manager of Baker-Jackson Nissan South gave me the news but he invited me to come on down and buy a 08 Titan. I asked if the differential problems had been fixed but he said he did not know. He said sometime the best thing to do with a bad truck is to just trade it in. What a guy! He needs to work in Nissan Consumer affairs. Driving one of the Titans past 60k is dangerous. I was going to install a Tru-Trac but I think I will just get that Diesel I have been wanting. Now which one to pick.
