2010 Harley-Davidson Flhtcutg

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.

One of the bolts holding the floorboard sheared off causing it to collapse. This happened when I placed my weight on the floorboard. If this had occurred when driving at speed (30 to 70 mph) I would have sustained serious injury or resulted in my death. I have researched this and discovered this is a common occurrence as noted on motorcycle forums. This raises the question how many cyclists have lost their lives or been injured when the foot support fails and results in the loss of control of the motorcycle. There was no indication the bolt was going to fail.

EXCESSIVE HEAT FROM EXHAUST SYSTEM CAUSES SEVERE BURNS TO UNDERSIDE OF RIGHT THIGH, KNEE AND CALF. PAINFUL BLISTERING OF THE SKIN IN MANY PLACES ON RIDER'S RIGHT LEG FROM HEAT, (NOT FROM CONTACT WITH HEATED OR HOT COMPONENTS) WHILE WEARING LONG JEANS OR OTHER RIDING GEAR.

THE MOTORCYCLE HAS RUN VERY HOT FROM THE DAY I BOUGHT IT 5/10/2011. EVERY TIME I HAD SERVICE, I COMPLAINED ABOUT THE HEAT FROM THE PIPES. I STOPPED AT A HD DEALER IN ALEXANDRIA, LA ON 9/17/2010, AND ASKED THEM TO CHECK THE BIKE. I WAS TOLD AT INSTALLATION THE PIPES HAD BEEN INSTALLED WITH NO REMAP OR HIGH FLOW FILTER. I WAS CHARGED $413.57 TO INSTALL THE NEEDED FILTER AND DOWNLOADED A NEW REMAP. I LEFT ABOUT 5:30 P.M. TO RETURN TO MADISON, MS. THE ONLY STOPS WERE AT GAS STATIONS TO FILL UP. THE VENTS ON THE FAIRINGS WERE WIDE OPEN. I RODE WITH MY LEGS UP FROM THE PEDALS BUT COULD FEEL MY RIGHT LEG GETTING UNCOMFORTABLY HOT. WHEN I REACHED MY DESTINATION, I PULLED UP MY PANT LEG. I SAW MY RIGHT CALF WAS BLISTERED FROM THE EXCESSIVE HEAT FROM THE PIPES. (I HAVE A PICTURE OF MY BLISTERED LEG.) I CALLED HD HEADQUARTERS AND THEY SAID I SHOULD TAKE IT TO A DEALER FOR SERVICE. THE LOCAL DEALER WAS NOT COOPERATIVE WHEN I CALLED TO TALK TO THE SERVICE DEPARTMENT. THEY SAID THE TRIKES RUN HOT . APRIL 2011, I WENT TO WILDCAT HD IN LONDON, KY BECAUSE THEY HAVE A TRIKE DYNAMOMETER. THEY TESTED THE BIKE AND IT SHOWED IT RAN A FEW DEGREES ABOVE ACCEPTABLE LIMITS. HD HEADQUARTERS REFUSED TO PAY FOR ANY MODIFICATIONS TO THE BIKE. IT COST ME $1470 TO INSTALL POWER DUAL HEADPIPES AND A SUPER TUNER AS WELL AS THE COST OF THE DIAGNOSTIC TEST ON THE DYNAMOMETER. THIS IS THE FIRST TIME SINCE I BOUGHT THE TRIKE THAT IT HAS BEEN A COMFORTABLE RIDE WITHOUT EXCESSIVE HEAT COMING FROM THE PIPES. IT IS STILL UNDER WARRANTY YET, HARLEY DAVIDSON DOESN'T CONSIDER THIS TO BE COVERED BY THE WARRANTY. I HAVE LOOKED AT THE WEB PAGES AT HDFORUMS.COM AND FOUND THIS TO BE A COMMON COMPLAINT WITH OTHER TRIKE OWNERS. THEY HAVE RECEIVED NO HELP FROM HD HEADQUARTERS. I FEEL THIS IS A SAFETY ISSUE THAT HARLEY DAVIDSON NEEDS TO ADDRESS AND FIX.

I WAS IN A ACCIDENT DO TO THE BRAKES ON MY 2010 HARLEY TRIKE NOT BEING ABLE TO STOP. ON 6-5-10 I REAR ENDED A FORD EXPLORER AT 50 MPH. AFTER LOCKING UP THE FRONT BRAKES, THE REAR BRAKES DIDN'T LOCK UP OR HELP STOP MUCH AT ALL. I COMPLAINED ABOUT THEM SQUEALING, AND THEM NOT ABLE TO STOP LIKE THEY SHOULD ,BUT I NEVER HAD TO STOP LIKE I NEEDED TO THAT DAY.. IT IS TOTALLY IMPOSSIBLE TO LOCK UP THE REAR BRAKES OR TO STOP HARD WITH THE REAR BRAKES. AFTER HAVING THE BRAKES LOOKED AT 6 TIMES AT LEAST AND TWO DEALERS DOING WHAT THEY COULD, INCLUDING REPLACING THE PADS WITH NEW STOCK PADS. STILL NOT HAPPY I HAD THEM REPLACED WITH LYNDALL BRAKES. THEY STOPPED THE SQUEALING BUT DIDN'T SEEM TO HELP WITH THE STOPPING BUT DIDN'T HURT ANYTHING EITHER. I CALLED H.D. ABOUT THIS PROBLEM BUT THEY MADE IT SEEM LIKE I WAS THE ONLY ONE WITH ANY PROBLEMS AND DIDN'T HEAR FROM THEM AFTER. MY INJURIES CONSISTED OF 4 BROKEN RIBS, TORN MENISCUS IN MY KNEE THAT NEEDS TO BE SCOPED OUT, I HAD PRIOR HIP PAIN BUT BECAUSE OF THE ACCIDENT I NEED A HIP REPLACEMENT 15-20 YEARS SOONER. FRACTURED A BONE OFF IN MY SPINE BUT THEY SAID WERE IT WAS WASN'T IN A SPOT THAT NEEDED SURGERY. ROAD RASH ON BOTH ARMS. HAD TO HAVE A TATTOO REDONE. MY BACK, LOWER BACK, HIP AND RT FOOT WAS BRUISED BADLY. THREE MONTHS OFF OF WORK, 17,000 DAMAGE TO BIKE, AND 18,000 DAMAGE TO MYSELF. I JUST GOT MY BIKE BACK 10-8-10 I KNEW AT THE TIME OF THE ACCIDENT I HAD PLENTY OF DISTANCE. I ALWAYS SAID I JUST COULDN'T STOP. IT WAS SAID THAT I MUST HAVE BEEN FOLLOWING TO CLOSE. I REMEMBERED THE FRONT BRAKE LOCKING UP AND PUSHING AS HARD AS I COULD ON THE REAR PEDAL. I KNEW FOR 3-5 SEC. I WAS GOING TO HIT THE TRUCKS BUMPER. 10-8-10 I PICKED THE BIKE UP AND ON THE WAY HOME I KNEW SOMETHING WAS WRONG WITH THE REAR BRAKES. LONG STORY SHORT ON MY WAY BACK TO THE DEALER I HAD TO STOP FAST AND ONCE AGAIN COULDN'T STOP. I KNOW FOR A FACT MY ACCIDENT WAS DUE TO THE REAR BRAKE SYSTEM NOT BEING BIG ENOUGH TO STOP THE TRIKE. *TR
