There are quite a few 2018 and 2019 GL1800 that have had a failing UBS bolt that breaks and locks up the engine. I believe this is the case with my motorcycle. I am a [XXX] disabled vet who was riding my motorcycle down [XXX] in NJ going 60mph when I began slowing down for the exit onto [XXX]. Just about as I got to the exit the engine all of the sudden made a noise and locked up and pulling in the clutch made no difference so it cam to an abrupt stop and I fell over. Luckily the traffic was able to negotiate past me. If I had been in the center lane I do not know what would have happened. I have not taken it to a repair shop because I believe with uncertainty what is the failure after reading all of the forums online about these transmissions locking up due to an inferior bolt which has been replaced in the newer bikes with an upgraded part. There were no warnings, symptoms or lights prior to the failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I was riding over the Commodore Barry Bridge when my transmission "locked" in 4th gear. The display showed 4 asterisks instead what driving mode the bike was in. I limped the bike to the closest dealer where it was determined that the Ratio Control Motor had malfunctioned. The motor along with the associated gaskets were replaced under the extended warranty that I purchased when the bike was new. The mechanic showed me the failed part that had burned contacts due to water intrusion into the housing.

2 INCIDENTS- MAY 26TH 2019 AND NOVEMBER 24TH 2019. AT A STOP ON A STREET - THIS MOTORCYCLE HAS THE HONDA 7 SPEED DUAL CLUTCH TRANSMISSION - TRANSMISSION IN DRIVE, THE GOLD WING TOUR DCT MOTORCYCLE ENGINE RPMS INCREASED WITHOUT OPENING THE THROTTLE CAUSING THE BIKE TO LEAP FORWARD UNEXPECTEDLY. THE FIRST OCCURRENCE IN MAY HAPPENED WHILE THE FRONT BRAKE WAS APPLIED WHICH WAS NOT SUFFICIENT AS THE ENGINE POWER OVERCAME THE BRAKES AND JUMPED FORWARD ABOUT 6 FEET - THE BIKE WAS STOPPED BY ENGAGING THE KILL SWITCH. THE SECOND TIME IN NOVEMBER MY HAND WAS NOT ON THE RIGHT HANDLE - THROTTLE - WHEN THE ENGINE SURGED UNEXPECTEDLY AND CAUSED THE BIKE TO GO FORWARD ABOUT 4 FEET BEFORE I COULD GRAB THE BRAKES AND STOP FORWARD MOTION. FORTUNATELY IN BOTH CASES THERE WAS NOT A VEHICLE IN FRONT OF ME......

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2018 Honda Gl1800a verdict →
