Acceleration / transmission problems with 2014 Nissan Pathfinder. Issues began at 3100 miles. No acceleration from stop, or very minimal. Felt as if the transmission was "slipping" and would not engage, or similar to drive a manual transmission at mph in 4th gear. Issue recurred several times on my commute home. Was stranded on the side of the road and required towing because I could not make the vehicle move forward at all. Abnormal burning smell coming from front of car was observed. I was stranded in winter with a 3 month old in the car. At one point I was basically stuck in the middle of an intersection due to the lack of acceleration. I was nearly rear-ended in one case and was in serious danger of being sideswiped by oncoming traffic. Depending on the situation, this issue could present a major safety hazard (and did for me). For the first time in my life, I was worried for my personal safety while driving a car. Also observed erratic engine rpm's at idle (from 1000 to 1500) and while coasting. Rpm would jump up and down with constant (or no) throttle applied. Dealer has had the car for over 3 weeks at this point. Initially they were not able to replicate the issue, and no error codes were shown on the computer. Eventually they did replicate the issue and are now replacing the transmission control module after consulting with Nissan. I have the impression that neither Nissan or the dealer has any clue how to fix the issue. They are just trying different things to see what makes it work again. Based on the lengthy list of similar complaints, Nissan is apparently not too concerned. . .
