When driving at various speeds I began to notice the engine bogging down when changing gears. Upon taking it to my mechanic I was told that there was a leak between the transmission and engine coolant systems. The fix would require a replacement of both systems totally approx. $6000! apparently this is a "known issue" with 2005-2010 Xterras. Upon contacting Nissan I was told that since my vehicle was over 100,000 miles that there was nothing that they could do for me. If this is a known issue, and a rather major one at that, I'm not sure why there hasn't been any recalls or some kind of fix.
Coolant leaked into the transmission, causing transmission failure. Estimate of $5800 to repair.
Engine coolant leaked into the transmission, causing transmission failure. Replacement transmission is required.
Driving on freeway and transmission began to slip and within a matter of seconds had absolutely no power to wheels. Have researched and found issues with this vehicle regarding coolant line for transmission failing and leaking anti-freeze into transmission. Was wondering why it is that there is not a recall by Nissan for this issue as it is undetectable, unpreventable, and expensive.
