While driving at normal road speed, my forward speed suddenly drops from 60 MPH down to 25 MPH, then 5 or 6 MPH on a highway. My right grip throttle control fails to work. The bike's etc, electronic-throttle-control, fails to communicate with my bike's computer or throttle-body. I have to limp home on the open road. This is dangerous. I've suffered 4 separate failures of my etc throttle control. Once at daytime, but 3 times at night. Someone from behind traveling at 45 or 55 or more might slam into me at night as my red taillight is on. I could easily get killed. My harley dealership knew of this failing as I called their senior tech the very first time the etc failed during rushour on a congested highway. After I got safely off the highway, the har-dav tech walked me through a computer diagnostic check. This worked for a couple of weeks, then 3 more etc fails at night on hwy 27 and county-roads and 1 city street while straight-driving. Frightening. Called triple-a & had my 2017, 5 month old bike towed backed to the har-dav shop. They report "no issues found." four throttle failures ? I don't buy their response. I told them to keep the bike & fix it. Also, asked them to call har-dav milwaukee for answers. They did not call. I had to call milwaukee & report this dangerous issue. Please help before I get killed on hwy 27, fl.
