NHTSA Complaint #11607446 — 2018 HONDA GL1800

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. My assessment is as follows: This motor is mounted to the rear underside of the engine and moisture can infiltrate and cause intermittent or complete failure. Possibly from a bad gasket? I had ridden 260 miles that day in the rain while on a trip. After stopping for an hour then restarting the bike, the failure occurred. It wouldn't go into gear (it's a DCT - automatic) and the warning lamps were flashing (see attachments). I was able to eventually, after several restarts of the engine, to get the bike drivable and get to my hotel where it failed again. Fortunately, it didn't fail while in motion or under acceleration, but it can. In fact, Honda mentions that in the owner's manual, page 181.
