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 secondary clutch actuator cylinder may leak fluid internally and the clutch master cylinder may lose the ability to generate enough lift to disengage the clutch.
The risk: If the clutch cannot be disengaged it can result in a loss of control, increasing the risk of a crash.
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.

The remedy: Harley-Davidson will notify owners, and dealers will inspect and correct the oil cooler line clamps, as necessary, free of charge. The recall began on June 6, 2017. Owners may contact Harley-Davidson customer service at 1-800-258-2464. Harley-Davidson's number for this recall is 0170.

The motorcycle was repaired under NHTSA Campaign Number: 18V734000 (Power Train); however, the failure persisted. The dealer was not contacted. The manufacturer was made aware of the failure. The failure mileage was approximately 45,490.

ABS module failure resulting in front brake locking up. ABS module failed resulting in brake failure. While I was not involved in any incident the failed part showed no signs of beginning to fail. One day I I got onto the motorcycle and when I went to squeeze the front brake it was hard as a rock and it locked up my front wheel. This particular failure happened in my driveway so nobody was in danger but it also had no warning lights on or gave any signs of failure prior to this incident. If this were to happen while riding the motorcycle it could potentially be deadly for the rider and passenger depending on riding conditions. The part failure has been verified by a Harley Davidson dealership. Parts to correct this are currently back ordered over a month. I do not have the part in my possession as the bike is at a local dealership. I do plan on asking for the failed part once it is repaired. I did have brake work done on this bike in June of 2022, (pad replacement and system flush), and rode this bike on several occasions since the service but prior to failure. The bike had sat for about a month with no activity (covered) prior to this failure. The service was not preformed at a Harley Davidson dealership. There was a prior recall on this system for earlier model bikes for this same type of failure. But my specific year/model was not included. I have read several complaints from other owners in the same date range as mine having the same failure. This is a potentially deadly situation that needs to be corrected as Harley Davidson simply wants to replace the parts and make money off of their poorly engineered design. This type of failure does not occur in a passenger vehicle ABS system.

Exterior lighting
Filed Jun 1, 2017

THE "DAY MAKER HEADLIGHT " FOUND ON THE HARLEY DAVIDSON ULTRA CLASSIC IS COMPLETELY UNUSABLE.IN USING THE LED BULBS ON THIS SYSTEM THE REFRACTORY NATURE OF THE LENS DICTATES THAT A HORIZONTAL LINE WITH LIGHT BELOW THE LINE AND DARKNESS ABOVE IT A DISTANCE KEEPS THE LIGHT FROM SHINING INTO THE ONCOMING DRIVERS. THIS WORKS FINE IN AN AUTOMOBILE, BUT ON A MOTORCYCLE, IT BECOMES UNRIDEABLE .THE REASON BEING IS THAT WHEN YOU LEAN INTO A CORNER THE HORIZONTAL LINE DIPS TO THE SAME DEGREE AS THE MOTORCYCLE, AND THE DARKNESS ABOVE DIPS DOWN WITH THE BIKE SO THAT IT IS NOT POSSIBLE TO SEE INTO OR THRU THE CORNER (IF YOU DO NOT UNDERSTAND THIS SITUATION PLEASE PASS IT ON TO SOMEONE WHO DOES). I AM NOT A NEWBIE TO RIDING AS I HAVE 30 YEARS AND ALMOST A QUARTER MILLION MILES UNDER MY BELT ALL ON HARLEYS I CAN ALMOST GUARANTEE THAT THIS HAS CAUSED NOT ONLY INJURIES BUT ALSO DEATHS. THIS LIGHTING SYSTEM HAS BEEN CHECKED AND CHECKED AGAIN AND IS IN SPECS ACCORDING TO HARLEY DAVIDSON I WOULD INVITE ANY SPECIALIST OR OFFICIAL TO RIDE THE DARK COUNTRY ROADS THAT I RIDE AND TELL ME THIS LIGHTING SYSTEM IS SAFE PLEASE LOOK INTO THIS IT IS UNSAFE AND WILL INJURE OR KILL PEOPLE
