They are fantastic. On my 2012 We have yet to have the gas tank issue. Even ran it down to almost empty, and no issue. These are very solid vehicles. The 3.5 and the CVT is very proven. One of the best engines made.
This is the biggie, its 100% made in Japan. Huge deal. I have a 96 toyota t100 100% made in Japan as well. Still have the truck and never had an issue with it, and I mean nothing. My bother works for Nissan and he is very big on the fact that it is 100% Japan made.
We love ours. We had a Maxima for 2 years and no problems with that either. They are making a great product!
