NHTSA Complaint #10468581 — 2006 HONDA GL1800

I WAS ACCELERATING IN THE ENTRANCE LANE ON THE INTERSTATE. AUTO AND TRUCK TRAFFIC WAS HEAVY AND AS I MERGED INTO THE TRAFFIC LANE THE MOTORCYCLE SHIFTED FROM 5TH GEAR TO FOURTH AND BACK SURPRISING ME AND CAUSING ME TO QUICKLY SLOW AND TAKE ACTION TO THE RIGHT TO AVERT BEING REAR ENDED BY A SEMI TRUCK. THE TRUCK HAD NOWHERE TO GO AS THE LANE TO HIS SIDE WAS OCCUPIED. I PROCEEDED TO GAIN SPEED AND THE MOTORCYCLE DID THE SAME SHIFTING ACTION EVERY MILE OR SO. I TOOK THE CYCLE TO THE DEALER AND WAS TOLD IT WAS NOT UNDER WARRANTY. I AM AT PRESENT HAVING THE TRANSMISSION REPAIRED AT MY COST. THERE WERE NO WARNINGS PRIOR TO THIS EPISODE. THE MECHANIC SAID THERE WERE SEVERAL FAILED COMPONENTS IN THE TRANSMISSION.
