NHTSA complaint #10886283, filed 2016-07, 24,000 miles

Electrical system: “While riding my 2008 street glide I would lose all response on the throttle, while on the interstate I had to coast to the side of the road until the throttle randomly began to respond. While on this particular trip the bike repeated this at least 10-15 times. The bike is being trailer to the dealer for review. This is definately a safety issue while riding bike on a busy interstate.”

Vehicle speed control: “While driving on a very busy highway at around 60 MPH I went to pass a car and while in the other lane passing I lost all throttle. This has happened numerous times and very dangerous. I have been riding motorcycles for 40+ years and can't even imagine what would happen to an inexperienced rider. I can not to this day get a straight answer from dealer's or mechanics. I guess this is all included in the $22,000 I dished out.very very dangerous. There are definite issues with the electronic throttle (fly by wire).”
