Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“The fuel pump for the engine is known for failing due to ethanol in the fuel reacting with the bare aluminum. Harley Davidson has recognized this issue with the newer model but has not recalled any of its previous models. This could cause a serious safety risk for the rider or other pedestrians on the roadway as this could cause the bike to suddenly lose all power causing an accident. Many people have mentioned this known issue but Harley Davidson still refuses to seal the aluminum tanks or replace the tank with the later model ones that are already sealed. …”
