All three of these shared engines and transmissions in the 2005-2012-ish ranges. The main 2 problems were that  A) Nissan cheaped out on the tensioner chain guides for the engines so around 130-150k they will start to fail and give off a high pitched whining sound. That must be corrected immediately or the guide can fail and cause everything to lose timing. B) The stock radiators have a transmission cooling line running through them that will fail. There are aftermarket radiators that fix this issue (I use a CSF brand aluminum radiator), but if left uncorrected the transmission fluid and coolant will mix, destroying the transmission. You'll see this referenced as SMOD, or the strawberry milkshake of death, because of the thick pink mixture the transmission fluid turns into. An interesting thing to note is that they made a V8 Pathfinder for a few years starting in 2008. If you find one they are solid vehicles but some of the mechanical parts for those models will be hard to replace. They no longer make a few of the parts, like the very specifically sized CV axles for only those models.As others have mentioned, do not get a Nissan with a CVT transmssion.</blockquote>
