Service bulletin 1HD-J9M8M-04

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Service Bulletin M-1444: 2016 TOURING, TRIKE, CVO CENTER FILL FUEL CAPS - OWNER NOTIFICATION OF DIFFICULT TO REMOVE OR INSTALL FUEL CAPS. Harley-Davidson has determined that some 2016 Touring, CVO Touring or Trike models equipped with center-fill fuel tanks may develop a swelling issue between the fuel tank fill neck and the threads on the fuel cap when exposed to certain types of fuel and environmental conditions. Harley-Davidson is conducting a notification by mail to U.S. and Canadian owners of record to inform them that if they have a fuel cap that requires extreme effort to install or remove outside of the original two-year Harley-Davidson Limited Warranty, it may qualify for repair coverage under the Harley-Davidson Emission Control System Limited Warranty.
