Example complaints

Brakes: “My 2010 harley davidson street glide lost rear brakes without warning pedal became hard as if it was stuck luckily I was traveling at a low speed. It's currently at a harley dealer and they tell me it's the ABS brake module and it needs to be replaced. If that isn't enough they tell me the part is on back order which tells me this is a common issue.”

NHTSA complaint #10927111, filed 2016-11, 1 miles

Electrical system: “I was driving down the road going about 50 MPH and my throttle shut off and the engine went into limp mode (shut off one cylinder). I had to cross one lane to pull off the side of the road so I could restart my bike. Luckily there wasn't heavy traffic or it could have been really bad. I see that this is a trend in these bikes and harley needs to do something.”

NHTSA complaint #10629975, filed 2014-09, 10,550 miles

Engine: “Engine lost all power. Had to cycle the ignition 3 times to reset. Diagnosis was a bad throttle body module. Dealer said it is a known issue and is happening faster than they can get the parts in to fix. Bike currently has been at dealer for 3 weeks and parts are still on back order. Harley davidson has not listed it as a recall.”

NHTSA complaint #10606438, filed 2014-06, 40,000 miles

Vehicle speed control: “The motorcycle goes into limp home mode and throws several codes which are all related to the throttle position sensor. This has happened to me several times at various speeds, RPM's, and throttle positions. I spoke with multiple mechanics and they advised me to first clean the connector at the throttle body. Cleaning the connections worked and I was able to clear the codes. After riding about 150 miles the same issue happened again and I ended up stranded in the middle of no where. This time I could not get the codes to go away. …”
