1. vibrations coming from rear of car at 35 mph. Vibration get worst when accelerating to 40 mph, shifts hard, RPM's increase then decrease(jumps all over the place). Occurs all the time. Faulty lines between coolant system and transmission. Coolant mixed with tranny fluid. Replaced, radiator, flushed engine, flushed tranny 2 times. Installed external transmission cooler and bypassed radiator, so this wont happen again, my have to replace transmission in future because of the damage done to it by the coolant mixing with tranny fluid. Out of pocket expense $1463.12 parts and labor at a local Nissan dealer. I was told that this is a common problem with Nissan 4X4 vehicles. This should be a recall. And if my transmission goes I feel that Nissan should replace it free of charge.

2005 thru 2007 nissa Xterras and pathfinders made in these model years have a defective radiator. The transmission line corrodes and coolant leaks into the transmission line and contaminates the transmission. Repairs have to made to the radiator, transmission and all associated lines.

Internal radiator failure that led to a transmission failure in the middle of the highway. I had the radiator replaced at a cost of $1,300 by the Nissan dealer where they assured me that the transmission was fine. A month later I paid $5,000 to aamco to have the entire transmission rebuilt. This has happened to countless 2005 pathfinders and Xterras. Nissan will not provide financial assistance or make a recall. Nissan needs to be held responsible!
