Technically not a safety recall, true. This is a Customer Service Notice (CSN) (or campaign). The Mopar Recall site,
https://www.mopar.com/en-us/my-vehicle/recalls/search.html, is their clearing house website for safety recalls, emission recalls, customer satisfaction notices, and warranty extensions. This is an issue with the vehicle, and will be checked and repaired if necessary at no cost to the owner. Semantics aside, it's a type of recall.
I'll attach the notice I received and the related TSB.
I'm happy for you that hose has not come off and is tight. My truck has been driving fine, as well - but I checked the purge valve hose latch for the proper color, and found that it's dark gray and should be replaced. So while it's ok today, there's a risk that it might not be tomorrow. Or maybe when I'm some distance from home on a long trip. I'd rather follow the TSB and have it replaced. Note that there are two issues covered by this notice/TSB - the purge valve hose and the canister purge tube. The hose is identified by color (shades of gray, unfortunately), and the tube is identified by p/n, as you noted. Did you check the color of the HOSE latch on your truck, in addition to the p/n of the TUBE ?
