For the record, I'm not gonna pull the switchero with the Fronty. My reply to that suggestion was tongue in cheek (or however that saying goes).
If you mean I shouldn't even ASK if they'll cover it, I don't agree with you. I doesn't hurt to ask. If they don't cover it, I'll move on to plan B (most likley try to clean it or find a 3rd party replacement myself). If they make this little concession, they'll have a loyal customer for life. If they don't, I might be inclined take a look at Toyota along with Nissan next time I need vehicle. No biggy - free market/customer service, that's all!.

General update: Just got back from picking up the truck at the dealer. The service writer (who knows me since I'm a regular there) said my best bet is to wait until the service manager gets back from vacation, because he thinks they'll probably do it under the good will thingy, but that has to be worked out between the service manager and Nissan.
