One problem related to transmission stuck in gear has been reported for the 2004 Nissan Murano. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2004 Nissan Murano based on all problems reported for the 2004 Murano.
The problem occurs on a hot day in stop and go traffic where once you come to a stop, when pushing the gas pedal down it takes a good 10-30 seconds before you get any response from the transmission, and when you finally do, it's very very slow as if the car is stuck in 4th gear trying to accelerate. While driving 30mpg+, it starts to feel like the car is pulling back, in an incorrect gear. Doing a quick search shows that many other owners of a Nissan Murano experience this problem, and that the dealership says that its the pressure sensor and the transmission needs replacement, costing between $5400-$7000. I have not contacted dealership yet but after reading other customer's complaints it doesn't look like I would have any luck getting this fixed without having to pay for a whole new transmission.
