Aug 18, 2024Engine1 injury

The UBS bolt broke off ( according to honda mechanics who worked on the bike) causing the motorcycle to lose all power instantly. The engine basically fell apart. I was traveling 55 miles an hour on a two lane curvy mountain road with virtually no shoulder and traffic in both directions. With no power I tried to pull off the road But could not as my first reaction was to grab the brakes, causing traffic to come dangerously close behind me. with on coming traffic I had no choice but to try and get off the road. There was a 6 to 8 inch drop off onto the grass (no shoulder) at this point I lost control of the motorcycle and struggled to keep from falling over- injuring my left leg, right arm, and left neck. Honda dealers and Honda have told me this is a problem they are aware of and have had several other cases of failure in the same way. The vehicle has been with the Honda dealership since April 29, 2024 This is a very serious and life threatening problem of which Honda is aware. My injuries are still on going.

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 Gl1800 verdict →
