2021 Honda GL1800

I was pulling into a parking spot to turn the bike around and back into the spot. While sitting sideways in a parking spot, I increased the throttle slightly to pull forward. The throttle acted as if it was stuck and the bike lurched forward after I released the throttle. I applied the front brake but the bike continued moving forward pushing the front tire which left a skid mark on the pavement. I continued forward until the bike ran into the driver's door of a parked car. This was the second time the throttle stuck in this manner. The first time I was leaving my driveway when the bike acted in the same manner and caused me to run over some Christmas lights on the edge of my driveway. The first time I did not realize what happened therefore I did not file a complaint. I researched this on a motorcycle forum and found many instances of other GL 1800 owners experiencing the same problem.

when just starting out using foot brake and handbrake , handbrake came in towards grip real far and throttle cut out but not off for a few seconds. Then abs and traction control lights came on along with mode selector lights until bike was shut down and restarted. Upon restarting all would be ok for a few miles or even the whole day or would just do it all over again. It did this from june until now where it is presently at the honda dealer while honda tries to figure it out. So far they have not.
