Answer 1

Depends what your exact problem is

there is a service bulletin for the 2008 model (2007 might be included if it was not updated) which say update the ECU

The dealer will charge $100 - $150 for the update, I'm not sure if the update has been done on your car before, call a local dealer or nissan and ask for the service information.
