sorry to hear about your problem. The good news is Honda acknowledges it- you're miles ahead of many. You are the 1st I've heard of having the problem at high speed.

All I can say to 'comfort' you is that any system, no matter how simple or complex, can have problems at any point. Unfortunately the gremlin decided to take up residence in your engine mounts (or rather, somewhere else, apparently). Complexity makes it easier to foul up, but anything can get fouled.

I hope the next-level technician can figure it out for you.
