Hello good people. Here's the official word from Nissan on the cube recall. Have a happy end of July / beginning to August and keep in touch! 

Based on the recently conducted government compliance test, Nissan has determined that the affected vehicles may not meet one of the applicable standards related to fuel retention after a high speed rear collision.

During the development of the cube Nissan conducted internal certification testing using the same procedures, and that test did not produce any fuel leakage.  The vehicle in the internal certification test met all the applicable requirements.  

To address this issue Nissan will install a protector on the fuel filler recirculation tube.  Nissan will begin contacting potentially affected customers in late August advising them to bring their vehicles to an authorized Nissan dealer for the installation of the protector.
 
There are approximately 5400 affected vehicles in Canada (45,700 in the USA).  Nissan has determined that cube vehicles manufactured for Europe and Japan are not affected by this issue because they use different fuel filler parts to meet the applicable regulations in those markets.
 
 No incidents or injuries have been associated with this issue.  Nissan is committed to a high level of customer safety and is working to promptly address this issue.
 
Nissan is currently procuring the necessary parts and will begin to notify affected customers in August 2010.
