Safety investigations
NHTSA inquiries naming this vehicle. An investigation is not a finding of a defect.
Sudden Brake Failure - Motorcycle
The Office of Defects Investigation (ODI) opened this investigation in July 2016 based on forty-three (43) Vehicle Owner Questionnaires (VOQ).During the course of this investigation ODI received a total of 145 VOQs related to the alleged defect on the subject motorcycles.Owners allege they experience a sudden and complete loss of brakes on one or both wheels.To better understand the cause of the braking issue on the subject motorcycles, ODI requested NHTSA's Vehicle Research and Test Center (VRTC) conduct inspections and testing of affected vehicle braking systems.Through its work, VRTC determined that deposits were forming on the valves in the Hydraulic Control Unit (HCU) of the Antilock Braking System (ABS). These deposits could prevent the proper function of the HCU and render the brakes ineffective.To understand why deposits were forming in the HCU, Harley Davidson completed an analysis of the Dow 460 brake fluid used as original equipment on the subject motorcycles and determined that it had stability issues if left in the brake system for an extended period of time.Harley Davidson found that if a brake fluid flush was not conducted as outlined in the owner?s manual for the motorcycles, and was left in the system for a period of time beyond their recommendation; deposits could form in the HCU.Through further testing, Harley Davidson identified an alternate, commercially available, brake fluid that did not have the same stability issues as the original fluid and could stop the proliferation of any current brake system deposits.ODI sent Information Request (IR) letters to Harley Davidson and Dow Chemical (the supplier of the brake fluid on the subject motorcycles) to collect information about the subject bikes and the alleged defect.Harley Davidson responded in full on Sept 30, 2016 and Dow responded with a confidential submission on October 25, 2017.ODI analyzed the information contained in both IR responses and concluded that motorcycles manufactured during Model Years (MY) 2008, 2009, 2010, and 2011 were failing at a rate greater than their peers.Based on this analysis and the brake fluid study conducted by Harley Davidson, a group of motorcycles was identified that were potentially affected by the instability of the original brake fluid.2008 marked the introduction of ABS on Harley Davidson motorcycles and a change in the Dow 460 brake fluid used in the 2012 MY vehicles provided the bases for the scope of the affected population.With recall action 18V-076 taken by Harley Davidson this investigation is closed as further use of agency resources does not appear to be warranted.The ODI reports cited above can be reviewed at: https://www.nhtsa.gov/ using the complaint identification numbers attached to this resume.

ABS System failure causing brakes to fail
- NHTSA ID
- 11458977
- Incident
- Mar 17, 2022
I was riding my motorcycle with a group of bikes and had to make an emergency stop. When the brakes were applied, as directed in the owners manual, the ABS failed and caused the rear tire to lock and skid. The resulting skid caused a loss of control of the motorcycle and ultimately laying the bike down on the asphalt highway. This resulted in the rider and passenger sustaining injuries. The passenger received a Tramatic Brain Injury which a month and a half later she is still in recovery. The motorcycle has not yet been repaired or looked at by any Police or Technical personnel. There were no warnings or lights prior to the accident.

I WAS TRAVELING ABOUT 35MPH AND APPROACHING AN INTERSECTION NEAR MY HOME. I HAD TO STOP QUICKLY AS A CAR TURNED INTO MY LANE JUST A HEAD OF ME. I APPLIED THE FRONT AND REAR BRAKES OF MY MOTORCYCLE BUT THE FRONT BRAKE LEVER DID NOT MOVE AT ALL. IT WAS AS IF IT WAS FROZEN IN PLACE. I HAD NO CONTROL OF THE FRONT BRAKES. I WAS ABLE TO SLOW USING THE REAR BRAKE AND AVOIDED A COLLISION BY STEERING OUT OF THE WAY. AFTER ARRIVING HOME AND INVESTIGATING, I FOUND THE ABS MODULE HAD FAILED. I ALSO FOUND THIS IS AN ISSUE KNOWN BY HARLEY DAVIDSON OF THEIR 2008-2014 MOTORCYCLES WITH ABS. THEIR SOLUTION, IS TO BLEED THE BRAKE FLUID EVERY TWO YEARS NO MATTER WHAT. I DO THAT MYSELF EVERY TWO YEARS. THERE IS NO GUARANTEE THAT IF I REPLACE THE ABS MODULE, AT SIGNIFICANT COST, THAT A FAILURE WON'T HAPPEN AGAIN.

SERVICE BULLETIN M1650: MILWAUKEE EIGHT AND TWIN CAM CAMSHAFT DRIVE GEAR RETENTION KIT CHANGES. PURPOSE: This bulletin informs dealers that changes have been made to the Camshaft Drive Gear Retention Kit and service proceduresfor the Milwaukee-Eight and Twin Cam applications. In an effort to increase the clamp load of the camshaft drive sprocket bolted joint and prevent the drive bolt from loosening in high lift camshaft applications, the following changes have been made: a. The camshaft drive bolt final torque has been increased to 40 ft-lbs (54 N·m) for all Milwaukee-Eight and certain Twin Cams models. See Vehicles Affected. This increase in torque will make the bolt a one time use application. Never re-use a camshaft drive bolt for service after tightening to the increased specification. See service manual for updated procedure. b. A new camshaft drive gear retention kit (Part No. 91800088) has been created. This new kit is compatible with all Milwaukee-Eight and Twin Cam engines using Parts and Accessories (P&A) camshaft and Original Equipment (OE) camshaft applications. See Instruction sheet for specific fitment on Twin Cam OE camshaft applications. The new kit utilizes friction washers to prevent unwanted rotation of components in the drive sprocket bolted joint under stress. The use of liquid threadlocker on the threads of the bolt and pre-lube to the head of the bolt flange and outside of the washer help the bolt reach full stretch when tightening. NOTE: Engines produced at all Harley-Davidson Motor Company (HDMC) plants will not come with the new kits installed. They will continue to be produced with (Part No. 25566-06).
