I got this in the mail a few days ago as well and taking my Xterra to the shop to get the tranny fluid checked. My wife and I purchased our used 2008 Xterra S in late 2010, and a month later, we had some acceleration issues past 60 mph when driving onto the interstate. It did feel like something was slipping at the higher speeds.
Dealership checked it out and found really dark BLACK transmission fluid - stuff that is clearly not meant to be in the transmission but couldn't figure what it was. Thankfully, they reimbursed me for the transmission flush.
Fast forward present date, I have reason to believe it was coolant with this case going on. Since the problem was never fixed, it possibly could reoccur.
If I am reading this proposal correctly, it still sucks because we would be responsible for the $2500 initial cost (8 yrs or 80,000-90,000 miles) or $3000 (9 yrs or +90,000 miles) and then Nissan would pitch in after. I hate law jargon so someone correct me if I am wrong. I guess if the amount was exuberant like +$6000 in the previous post, some assistance is better than nothing, but its not our fault Nissan has this issue. It is their fault!
