Transmission Noise problems of the 2008 Nissan Pathfinder

After months of searching for a good used car, I researched, verified, test drove, and got an independent mechanics check on a 2008 Nissan Pathfinder sold by a private seller as "in perfect and excellent working condition" bought it on a Saturday nite, drove it 20 minutes home, then drove it for the next first time two days later on a long 200 mile trip out of country. I began to hear the strange high pitched noise along the way. When I arrived to my destination,I immediately contracted a mechanic who diagnosed the problem as internal, recommending I take to Nissan for accurate diagnosis. I also called 4 diff Nissan dealerships, and who diagnosed the timing chain issue over the phone,. I also called Nissan corp and opened a claim was advised to get formal diagnosis from a dealership. I anxiously drove back the 200 miles and took it to dealership. Fyi, I contacted original seller who stated again she knew nothing of the problem but could not help. I now have formal documentation of the timing chain problem and repair estimate $1,650, also, I was advised to immediately replace my radiator due to a well known, documented problem with leakage into the transmission on this car. I also did more research finding hundreds of documented complaints regarding the two above faulty and well known problems with the Pathfinders and a class action lawsuit! my new $10,500 car is sitting in my driveway, after only driving it one time im looking at $3000 worth of necessary work, and I will still be afraid to put my 3 daughters into this vehicle uncontrolled acceleration! Nissan has yet to get back to me, it is unbelievable that Nissan has no responsibility for these serious issues. Many complaints have been reported . When will the government make Nissan take responsibility? I saved and hitched rides to find and buy a car, and now I have none and no money~!.

Our Nissan problems started years ago. In 2010 I started noticing noise and shuddering coming from the transmission. I brought it in to the dealer and they said it was nothing more than it needed a flush of the transmission fluid. So I paid the $150, had it done and went on my way. In 2011 is started doing it again, had it checked and they said nothing was wrong with it I must have been hearing things. They test drove it numerous times and 'never heard anything'. Eventually they had a specialist come and look at my car. He determined that my a/c unit needed to be reset. Everything seemed to be fine and we went on our merry way. Flash forward to July 2013. On the way home from a road trip, about 3 hours from our house we started noticing it was getting hot in the car. Sure enough the air just started blowing out hot air. Everything still worked on the a/c, just blowing hot air. So we drove home sweating our a$$ off in mid-summer in FL. A day or 2 later we are driving down the road and the service engine light came on (1st time ever in this car). Husband thought he should shut the car off. . . Well, that was the last time my car ever worked. We had it towed to a mechanic where it sat there for 2 weeks. First he determined it was a blown fuse - great, $10! - went to pick it up and it blew again. He then determined it was a broken computer told us to tow it to Nissan. We did. It has been there for a week and we were just told that the trans & radiator fluids mixed and caused trans to seize causing a/c and electrical issues as well. They claim they've never heard of this before. . . Yea, right! Nissan won't do anything but has told us to call the class action lawsuit # and file a complaint. . . Oh and they'll give me $500 for a car that's worth $6,000+. They knew about this issue and never told me about it in the years that I brought up the issue. Beware of Nissan!.
