“My motorcycle suffered a serious engine failure at approximately 12,500 km (7,800 miles) while I was riding. Before the failure, I noticed an unusual ticking/rattling noise coming from the engine, especially when the engine was under load or when the throttle was closed. The failure occurred while riding and caused a sudden loss of engine performance. This happened while I was in traffic and I was extremely close to having an accident because the motorcycle did not respond as expected when I needed power. …”

NHTSA complaint #11766287, filed 2026-09“The stator/ rotor on the 2021 Pan America will fail resulting in engine failure, leaving the rider exposed in traffic or stranded. In my case the amp gauge went below 12 and the battery light came on while riding in traffic. Even while running the engine at high RPM's the amp's won't reach 12 (positive charging). My motorcycle died while idling at two traffic lights. I was able to get it restarted and make it home before the battery completely drained. I talked to the local Harley Dealer, and have read forum reports. …”

NHTSA complaint #11689629, filed 2025-09“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. …”
