Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

From owner reports, verbatim

Suddenly when riding the motorcycle I discovered a massive fuel leak from the gas cap on to the front cylinder head. I immediately pulled over and inspected the gas cap for tightness. I found that the gasoline cap was sufficiently tight and the sealing surface of the o-ring was okay as well. The gasoline appears to be leaking from the center of the cap where it pops out and lets you turn it. I was not able to tighten the cap in a way that would stop fuel from flowing out of it. I can’t see any seals inside the cap and don’t want to inspect and damage it if this would be beneficial for Harley Davidson to inspect. I am able to duplicate the failure every time I tilt the motorcycle side to side.

Too few reports in this category for a page of its own — they appear in the full complaint list.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
