The evaporative emission vapor vent tube, which according to my understanding is part of the evaporative emission canister, had its warranty extended to 150,000 miles or 15 years, whatever comes first. ONLY the vent tube, not the entire canister, is covered.
When a clog occurs, the software in the vehicle may not be able to pinpoint the issue, and so it likely won't throw a code that it otherwise should throw. This can lead to the problem continuing without being addressed for a long time, since neither the driver nor any dealer service technician or independent mechanic would be aware of the problem until the symptoms become severe and the "hard to fill" condition becomes a major inconvenience.
If there is any other problem related to the canister itself, the check valve, or any other part of the emission system that is properly detected by the vehicle's software and appropriately causes the check engine light to turn on, that other problem will NOT be covered under this extended warranty.
Again, this is for a 2013, but I would be surprised if this same limited extended warranty wasn't uniformly applied to all first generation Rogues, including 2014 and 2015 Select models. A call to Nissan USA corporate customer service should confirm this rather easily.
In my interpretation, the vent tube itself is not defective or poorly designed, and there's nothing about it (compared to other vehicles that don't have this software problem) that makes it more likely to cause a potential clog to develop. Such a clog is somewhat rare it would seem, in both the Rogue and other vehicles. It is only the Rogue's software and sensors that are designed poorly, so if a clog should occur, it is less likely to be detected by a sensor than in other vehicles suffering a similar clog of the tube.
