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.

Latest Aug 5, 2019
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.

VISIBILITY

Aug 5, 2019
12,733 units potentially affected
The defect: Harley-Davidson Motor Company (Harley-Davidson) is recalling certain Touring and CVO Touring motorcycles, including 2017-2019 FLHTCU, FLHTCUL, FLHTK ANV, FLHTKL, FLTRU, FLHTK, and 2016-2019 FLHTKSE, FLHTKSE ANV, and FLTRUSE models equipped with a Harley-Davidson Detachable Tour-Pak Luggage Conversion Kit (Part numbers 53000291, 53000291A, and 53000567). The kit did not include replacement rear red reflectors for the ones that are eliminated by installing this kit. As such, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."
The risk: Without the rear red reflectors, the motorcycle has reduced visibility to other drivers, increasing the risk of a crash.
The remedy: Harley-Davidson has notified owners, and dealers will install the replacement reflectors, free of charge. The recall began August 19, 2019. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson's number for this recall is 0629.

The remedy: Harley-Davidson will notify owners, and dealers will install a new secondary clutch actuator piston assembly, free of charge. The recall began November 5, 2018. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson's number for this recall is 0173.
