Nissan fail

My wife was driving along one day and our Nissan Pathfinder transmission broke down. This happened in fast traffic and with my baby in the back, not exactly the safest situation. This is a known issue, seemingly a crack happens in the radiator that spills into the transmission fluid rendering the transmission useless. So Nissan extended the drivetrain warranty to 80,000 miles, problem is my Pathfinder has 90,000 miles. Call me crazy but why does a known design flaw become my problem ever? Wear and tear is one thing, design flaws are another.  I'm going from one of Nissan's biggest fans to never wanting to buy a Nissan again. Nissan is failing to recall this known problem or at the very least help me not become a hater. What a lost opportunity. Nissan failed. Here's the kicker, I was about to buy a second Nissan, obviously their reaction won't allow me to do that now. I called Nissan to see what they can do and I have received nothing but juniors who are not allowed to deviate from a script. The supervisor is not interested in connecting with me, it's so obvious they are taking a head in the sand approach. Is this really happening, especially after the Toyota pedal recall implications. Here is the proof this is not a isolated incident http://www.carcomplaints.com/news/2012/nissan-transmission-investigation-possible.shtml
