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 Oct 18, 2018
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.

The contact owns a 2018 Harley-Davidson FLHR Road King. The contact stated that upon start of the motorcycle there was an abnormal grinding sound coming from the motorcycle without warning. The contact had taken the motorcycle to a dealer where he was informed that the gears inside of the transmission were breaking apart and that the transmission needed to be replaced. The dealer was able to order a new transmission and replaced the transmission under warranty; however, despite the repair, the failure returned and the contact returned the motorcycle back to the dealer. The contact had attempted to reach the manufacturer on numerous occasions but was unsuccessful after each attempt. The motorcycle had not been repaired and remained in the possession of the dealer. The failure mileage was approximately 6,100.

THIS IS A DESCRIPTION OF THE DRIVABILITY PROBLEMS CAUSED BY THE EXCESSIVE PRIMARY CASE FLUID. WHILE IN MOTION ON A CITY STREET THE MOTORCYCLE WOULD SOMETIMES NOT SHIFT DOWN FROM 3RD-2ND OR FROM 2ND TO 1ST GEARS. THIS CAUSES PROBLEMS WHEN TURNING AND WANTING TO USE ENGINE BREAKING TO SLOW DOWN DURING THE TURN. I COULD NOT USE THE ENGINE BREAKING AND WOULD HAVE TO USE THE BRAKES QUICKLY AS TO NOT CAUSE AN ACCIDENT. ALSO, WHEN SITTING STILL WITH ENGINE RUNNING IN NEUTRAL AT A TRAFFIC LIGHT, THE TRANSMISSION WOULD SOMETIMES NOT SHIFT FROM NEUTRAL TO 1ST GEAR. THE DELAY IN TRYING TO PROCEED CAUSES OTHER MOTORISTS TO ALMOST RUN INTO THE BACK OF MY MOTORCYCLE. THIS WAS MOST DANGEROUS WHEN TRAVELING IN A GROUP OF MOTORCYCLES RIDING CLOSE TOGETHER. ALSO, DURING AN EMERGENCY STOP CONDITION WHEN TRAVELING ON A CITY STREET ABOUT 50 MPH IN 5TH GEAR, IT IS VERY DIFFICULT GET OUT OF THE WAY FROM CARS OR TRUCKS BEHIND ME. THIS IS BECAUSE YOU MUST BE IN A LOWER GEAR THAN 3RD TO GET OUT OF THE WAY ONCE YOU HAVE COME CLOSE TO STOPPING. MOTORCYCLES CAN STOP MUCH QUICKER THAN CARS OR TRUCKS. IF I CAN'T GET OUT OF THE WAY, I COULD BE INJURED OR KILLED. HARLEY-DAVIDSON TRIED TO FIX THIS ISSUE IN OCT '19. UNDER WARRANTY THEY ADDED A BREATHER KIT PART# 26500027. MY DRIVABILITY ISSUES STARTED ABOUT 6,000 MILES AFTER HARLEY-DAVIDSON SAID IT WAS FIXED. AFTER DRIVING ABOUT 6,000 MILES THE DRIVABILITY PROBLEMS STARTED. AT THAT TIME, I CHANGED THE PRIMARY FLUID AND FOUND 7 EXTRA OUNCES OF OIL. WHEN PUTTING IN THE CORRECT 30 OUNCES OF FLUID THE DRIVABILITY ISSUES STOPPED. SEE ATTACHED TA0022 HARLEY-DAVIDSON KNOWS THE ISSUE. # DEAD? THIS IS FROM PAGE 149 OF MY HARLEY-DAVIDSON OWNER'S MANUAL. NOTICE: DO NOT OVERFILL THE PRIMARY CHAINCASE WITH LUBRICANT. OVERFILLING CAN CAUSE ROUGH CLUTCH ENGAGEMENT, INCOMPLETE DISENGAGEMENT, CLUTCH DRAG AND/OR DIFFICULTY IN FINDING NEUTRAL AT ENGINE IDLE. *TR
