What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2007 Harley-Davidson Flstn, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

From owner reports, verbatim
AFTER COMING TO A STOP AT A STOP SIGN, MY WIFE WENT TO ADJUST THE SIDE MIRROR AND THE ENGINE SHUT OFF. INITIAL ATTEMPT TO RESTART THE BIKE HAD NO RESPONSE, BUT AFTER REPEATED ATTEMPTS THE BIKE STARTED. THE RIDE COMPLETED WITHOUT FURTHER INCIDENT, BUT WHEN I TRIED TO RESTART THE BIKE THE FOLLOWING DAY THERE WAS NO RESPONSE. THE BIKE WAS TRAILERED TO A LOCAL HD DEALER, AND THEY DIAGNOSED THE PROBLEM AS A FAULTY IGNITION SWITCH. I TOOK A VIDEO OF THE ISSUE BEFORE REPLACING THE SWITCH WHICH SHOWS THE LIGHTEST TOUCH OF THE SWITCH WILL CAUSE THE ENGINE TO SHUTOFF. THE SWITCH MUST HAVE BEEN BRUSHED BY MY WIFE'S JACKET WHEN ADJUSTING THE MIRRORS AT THE STOP SIGN. *TR
