2018 Honda GL1800 Electrical system Problems

“The engines stops sometimes when I stop at an intersection and start to take off. Many times the transmission makes a loud clunk and the engine stops. It appears like the bike try's to engage both transmissions at the same time. Several times I could not get the bike restarted. I took it to two different Honda dealers but they cannot find the problem. I have found other 2018 Honda goldwing dct owners that have had the same thing happen to them and Honda tells all of us they never heard of this problem. …”

“I was seated on my 2018 dct goldwing, having just rolled back out of parking space in the church parking lot, (I did not use the reverse function) it was running, when I pushed d for drive it shot out forward on it's own, as if the throttle was wide open. Within 1 second or less I rear ended another 2018 goldwing about 1 car length in front of me. We both crashed. No significant bodily injury to us. But this could have caused serious injury of death to bystanders in the parking lot if we had hit them. I was not twisting the throttle, as the parking lot was crowded. …”

“I was pulling into the parking lot of a restaurant and stopped briefly to decide where to park. When lightly applying the throttle to pull into a parking space the engine revved up, the bike surged, and my wife and I crashed into a picnic area. This GL1800 DCT motorcycle has no clutch lever or foot shifter because it has a 7-speed automatic transmission. Therefore it wasn't possible to stop the rapid acceleration by pulling in a clutch lever, and activating the kill switch would have required taking my hand off the right hand grip as we ricocheted off picnic tables. …”

“The BOLT holding the Alternator/Starter or ISG unit BROKE. While this caused no injury as the Alternator stayed together, it could have caused the motorcycle to shut down while riding. The Honda Dealer replaced the Alternator under the Honda Extended Warranty. There were no symptoms, lights, or warnings.”

“31300-KVZ-632 1.00 MOTOR, RATIO CONTROL - this is the part that failed. It is not available for inspection as the dealer has replaced the failed part under warranty. The safety risk is, if it breaks under acceleration, you are stuck in that gear so merging onto an interstate you could in fact be run over. Yes, the dealer confirmed and replaced the component. Yes, there were warning lamps including the check engine light. After starting and restarting the bike several times it cleared, and I rode the bike to the hotel (approx. 10 miles) and then it failed again. …”
