 My originally bought this vehicle from Tennesee. No rust great when we had it at first! 1 year later the COOLANT IN THE RADIATOR WAS MOXONG WITH THE TRANSMISSION. Of course there's no way of cleaning it unless YOU REPLACE THE WHOLE TRANSMISSION. I spent more than $6k fixing this vehicle. I went to the Nissan Dealership and said it's A MANUFACTURER DEFECT PROBLEM THAT MANY THOUSANDS OUT THERE ARE GAVING THE SAME ISSUE. And they can't help you unless ur vehicle is less than 100k miles. Mines at 140k right now. So disappointed I have been at multiple auto shops including Nissan dealership fixing this truck. Apparently when they designed the vehicle the SMART DESIGNERS couldn't figure out that once the coolant started mixing with the transmission it would cause it to damage and the computer was out. I had to reset the computer programming for $2k at Nissan dealership and that doesn't even include the $4k I spent buying a rebuilt transmission. Stay away! I honestly discourage u buying this vehicle. I am giving an honest review. If you want to spend every 3 months at the auto shop be my guest!!!!!  Nissan needs to address this issue.
