Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“No events other than poor workmanship. Horn doesn't work. Safety is my concern. Harley-davidson says there is nothing wrong with my horn. They say that at 2000 RPM when you press the horn button it works. Sitting still or idling the horn will not work. They say no one uses the horn at idle or sitting still. If I am sitting at a light and someone turns into my lane I need to warn them. Harley says put it in neutral and rev the engine to 2000 RPM then blow the horn.”
NHTSA complaint #10157047, filed 2006-05, 20,000 miles“Harley davidson horn doesn't work. The horn was replaced at 1000 miles. Still doesn't work. It sounds like a wounded duck. Harley dealer says the horn is fine and that you must be running the engine at 2000 RPM for the horn to work. It worked fine when purchased. I say its a defect in manufacturing. If you need the horn you must be driving at 2000 RPM or better. Makes no sense. You must investigate this problem. Someone will get hurt.”
