I have a 2007 Murano and recently installed the 4th radiator. All of them have split at the seam where the aluminum parts meet the plastic parts. The first radiator went out at 40,000 miles and wasn't covered under warranty. The second lasted about 8 months, the third lasted about 3 months. The fourth was installed around 53,000 miles. I now have about 2 months on it and am wondering how long it will last. The
dealer doesn't know of any reason for all the failures. I called Nissan of North America. They too are oblivious of any radiator issues. But, obviously something is wrong. Anybody got any ideas?
