Example complaints

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

“The throttle by wire failed while riding. I had a total loss of power and nearly caused an accident from behind. The dealer blamed corrosion on the circuit board of the induction module. Coating the connector is a temporary fix. After the 3rd failure I had it towed and had a new induction module installed. I spent $450 fixing a known problem with a wide range of the most popular hd motorcycles.”

“While riding down the I 65 south, I attempted to pass a 18 wheeler on the left. As I did I noticed the car in front swerve into my lane and I tried to throttle to get over and I lost power nearly slamming into the other car. Yesterday as I pulled out to merge onto the hiway I again lost throttle(power) and had to swearve to avoid being hit by on coming traffic.”

“While stopped at red light, as the light turned green, I proceeded to apply throttle with no response. Let out clutch and rolled no faster then 20 MPH while cars were backing up behind me. After rolling at 20 MPH for approximately hundred yards, I was able to pull over in a safe location with out being run over.”

“I was just riding down the I-405 freeway near seattle, wa at about 70 MPH in the left with no shoulder available to pull over onto. The throttle suddenly failed and I had no power. I slowed dramatically and was nearly run over by a truck. I put on my flashers and moved 3 lanes right to get to the shoulder on the right. Traffic was heavy and I was fortunate not to be hit when I had no throttle control. I called a friend and he came about an hour later and towed me home. I feel that I was lucky not to have been hurt or killed in this incident.”

NHTSA complaint #10748784, filed 2015-08, 60,128 miles

“The problem began around april of 2012. When I started the motorcycle, there was no throttle response. The motorcycle will idle at 1000 RPM but the throttle will not work when twisted to accelerate engine. It remains at idle. It has happened several times and I have to disconnect the battery in order to reset the electronic throttle. Sometimes it works, other times it does not. It also happened various times when motorcycle was in motion at speeds of 45 MPH almost causing me to get struck on highway from behind by another vehicle. …”
