Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was exiting the freeway at 55mph when I slightly banked right, the engine died. I coasted to the side, turned the ignition switch off, then back on and it started and ran perfectly. The engine died again while entering the freeway at a later time. Again, I was banking to the right on a sweeping turn. The bike started as before after coasting to side of the onramp. I rode without a problem until I entered the freeway at the same on ramp a few hours later. The engine died in the same exact place. This is a dangerous situation!”

“Several times over the past 2 years I have lost ability to control my throttle. Throttle position closes and does not accept inputs from the accelerator. Several times while traveling on the expressway the throttle has shut and the motorcycle went into 'limp home' mode. This will only allow a speed of approximately 10-15mph (dangerous while traveling at high rates of speed). The concern is well know by the harley davidson company. They have even issued a technical tip bulletin (#tt418a) on the subject. However, no voluntary or required safety recalls have been issued for this concern. …”

“Ecm plug caused bike to buck and run erratically. Brought back to dealer numerous times until they changed the plug. They blamed on the aftermarket seat made by mustang seat for the bike but it happened with the stock seat as well. It seems others are saying the same happened to them with stock seats.”
