Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“I was on a 4 lane highway in the passing lane traveling at 55mph when I lost my throttle response and the bike went to an idle mode. I almost was hit while coasting off of the highway. This bike also went to the idle mode after starting it one time last year and I had to restart it 3 times to get it to respond. I just thought it was a computer glitch. When this occurred at 55mph I feared for my life and took it to the dealer on june 10. There is no recall on it. My dealer does not have a replacement part (fuel induction module) nor does harley davidson mfg. …”

NHTSA complaint #10605492, filed 2014-06, 30,000 miles

“Multiple times while ridding my Flhtcu the bike goes to limp mode no throttle,at multiple speeds, with little to no warning. After tones of researching, hour of labor, and a tone of money, the issue still exist and I am at but a lose. During research I fond this issue to be a very common one with multiple hd models. Due to the poor quality of the materials, parts, and engineering designed used to cause such a extremely dangerous safety hazard, any where on the road. I am requesting hd to be held responsible and to generate a recall to fix this safety issue for their costumers. …”

NHTSA complaint #10759798, filed 2015-08, 3,700 miles

“As per service bulletin ; tt418-a ,electrical connector corrosion and fretting causing the engine to shut down due to vibration . This situation is hazardous as the bike can fail in heavy traffic and intersections . Harley davidson is aware of this situation sense 2008 . As to date there is no recall planned.”

NHTSA complaint #10584426, filed 2014-04, 23,000 miles

“Bike went into the limp-mode while riding on interstate 80 near joliet, illinois. When in the limp-mode the engine continues to run but there is no throttle response which is extremely dangerous, especially if there is no shoulder to pull off onto. This has happened at least 20 times in the past year and Harley-Davidson denies a problem exists. However, Harley-Davidson has issued two service bulletin's to their dealers (tt418 and tt418a to address this problem to no avail. I guess a few people will have to die before they have a recall to fix their faulty parts.”
