Earlier R51's are a lot more prone to the problem. 2005 though 2007 are the heaviest hit... I've heard of a few 2008's and one 2010 reported the failure here at the forum. So far, we haven't heard of any 2009 models, yet. According to Nissan, the 2005-2010 models are in the range of those affected. The key is to address the issue and not wait for the warning signs, especially if you are out of 8 year/80000 mile warranty ( the warranty goes to 100,000 miles, but it costs you after 80000 miles). The "early signs" of the problem include signs of ATF in the coolant or water (white streaks or custard) on the AT dipstick or in the drained fluid. Another sign is slipping or clunking when shifting, but usually by that point, it's too late. I would check the CARFAX report before purchasing one. The ones that are affected are mostly in North American. I believe someone in Australia report a problem and I don't recall hearing of problems with those made in Spain (they seem to suffer from broken rear door handles for some reason). If you buy one and want to take preventative measures, you can do the "bypass method," which involves removing the cooler hoses from the radiator and just using the factory installed auxiliary trans cooler in front of the AC condenser, on the right side. The other option would be to replace the radiator. The genuine Nissan radiator is supposedly updated, but lists for $550. Griffin Radiators was making an all-aluminum radiator for about the same price. Many are going with a new, aftermarket radiator. The Canadian-made Spectra Premium is a popular choice for around $130-160. I got a Chinese-made radiator from Parts Xpress on Ebay about 2 years ago. Back then it was $92 w/ free shipping and a lifetime warranty. It seemed well-built and I've had no problems. Last time I checked it was down to $73.
