A couple weeks ago I took my 2010 Murano to a nearby Nissan dealer to check out a loss of power, especially going up hills, intermittent hesitation when accelerating from a stop and a recent episode of it going into limp mode, almost stalling out. The dealer did a diagnostic on the car and said that error code P0868 for the transmission came up, which they said means that the transmission needs to be replaced. They said that my only options are to replace the transmission, which would be almost $6K or to get rid of the car. I then contacted different Nissan dealer nearby and they said that it would be worth it for them to take a second look at the car to make sure I really do need a new transmission. The service tech got back to me and said that they checked the car out and said that the car's computer needed a software update for the transmission, which they now downloaded. He said for me to give the car a try to see if that resolves the hesitation and performance. He said that he's had other Muranos that needed that update and their transmissions kept going with no problems. That apparently has worked for my car, as it now runs extremely well, has full power again with no issues at all. Is it possible that it only needed a software update for the transmission?
