Transmission Sensor problems of the 2007 Nissan Xterra

Our car had no pickup when taking off from stop light and making a left turn. We were crossing traffic which made this quite scary as we almost stalled in the middle of the road. We pulled into a parking lot and turned it off. Wouldn't start back up and the gear indicator on the dash wasn't showing which gear it was in. Had it towed to the dealership and was told the coolant leaked into the transmission, which is a known problem with this car, and contaminated the transmission and the sensors. I was never contacted about this issue so I didn't know about it until I went online and saw all of the other complaints from people with the same issue. I just went over the 100,000 mile mark this year so Nissan will not fix it. I don't understand why this isn't a recall issue instead of a warranty extension issue with Nissan willing to cover the cost over $3,000. Who has $3,000 that they can afford or even have for that matter? I've filed a complaint with Nissan and am hoping that someone will help me either pay for this or give me full fair market value for the car so I can buy another one and use this as a trade in. Not sure that I'll buy a Nissan though, if they don't take care of me, that's for sure. The other issues that I've had with this car is the fuel sensor went out, which I've also seen other complaints on and the windshield wiper motor on the passenger side has gone out. Not sure if this has been something that others have experienced or not. All in all this has been a great car,but considering I bought it used with very low miles on it and just made my last car payment 4 days ago, I'm absolutely sick over this. Even worse is the fact that we could've been killed by oncoming traffic but were fortunate enough that the car did make it before any cars got too close to us. Is that what it's going to take before Nissan does something?.
