Recalls, owner-reported complaints, investigations and safety data

Data refreshed

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.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.
0
InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.
0
Crash or fire reportedComplaints whose submitter recorded that a crash or a fire occurred. These are the reporter's own answers on the NHTSA form, not verified findings.

THE BIKE WAS OPERATING NORMAL AFTER AWHILE IT STARTED TO SHAKE AT ABOUT 65 MPH. AFTER ABOUT 20 MIN IT SEEMED LIKE THE TIRE WAS LOOSE. NOW IT SHAKES SO BAD I CANT DRIVE IT. CORNERS ARE HARD TO KEEP CONTROL UNDER NORMAL DRIVING CONDITIONS. IT WILL SHAKE WHEN YOU ACCELERATE AND IT WOBBLES WHEN YOU DECELERATE. I HAVE A FEELING IT COULD BE A MOTOR MOUNT. AT A LITTLE OVER 10 THOUSAND MILES YOU WOULD ASSUME THAT WOULDN'T HAPPEN. THE BIKE SEEMS TO HAVE LOST SOMETHING I DID NOT SEE ANYTHING MISSING AND NOTHING SEEMS LOOSE. I DROVE IT ABOUT 60 OR SO MORE MILES AND PARKED IT. I JUST BOUGHT THE BIKE FROM HARLEY ON THE 25TH OF MARCH. 2 DAYS AGO. I FEEL LIKE READING ALL THE FORUMS ONLINE EVERYONE SEEMS TO HAVE A COMMON ISSUE WITH THE MOTOR MOUNTS AT EXCEPTIONALLY LOW MILES. I FEEL LIKE THIS SHOULD BE A RECAL ISSUE. HAD THE CONDITIONS OF THE ROAD BEEN BAD I FEEL LIKE I WOULDN'T BE ABLE TO KEEP THE BIKE UNDER CONTROL. THE FRONT TIRE ALMOST BOUNCES AND THE REAR END FEELS LIKE ITS SLIPPING ON ICE.

I WAS DRIVING ON CITY STREETS COMING UP TO A STOP LIGHT. I GENTLY GRABBED THE FRONT BRAKE TO START MY STOP WHEN I HEARD A LOUD POP. THE BOLT THAT CONNECTS THE BRAKE LINE TO THE MASTER CYLINDER CAME LOOSE AND BRAKE FLUID SPRAYED ALL OVER. AS OF THAT MOMENT, I HAD NO MORE USE OF MY FRONT BREAK AND BECAUSE THE FLUID SPRAYED ALL OVER IT GOT ON THE RIGHT FOOTPEG AND REAR BRAKE PEDAL. IT WAS DIFFICULT TO KEEP MY FOOT ON THE PEG AND UTILIZE THE REAR BREAK. WHEN I GOT HOME AND WAS ABLE TO INSPECT THE ISSUE CLOSER I FOUND THAT THE THREADS IN THE MASTER CYLINDER THAT HOLD THE NUT IN HAD CORRODED AWAY. THE BRAKE FLUID IN THE RESERVOIR WAS GRAY FROM THE METAL AND IT APPEARS THE PROBLEM HAS BEEN GETTING WORSE OVER TIME. THE BIKE HAS ONLY 8K MILES ON IT, AND I DO NOT BELIEVE THIS TYPE OF DEFECT SHOULD HAVE HAPPENED. I NOW HAVE TO REPLACE THE MASTER CYLINDER IN ORDER TO SAFELY OPERATE THE MOTORCYCLE.

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. Older model years have had longer for reports to accumulate.
