On references to goodwill, personally I never expected anything. Exact words, "worth a shot". All factors listed here considered, it was imo. As for any change in diy in habits, as long as I'm able that's not happening. So even knowing what I know now about dealer goodwill in this instance, wouldn't change a thing. Had I purchased the extended warranty offered at time of purchase, there would have been a 'minimum' $100 charge. Add in warranty cost, it's still far more expensive than my outcome.
And should be considered, there's zero guarantee that even had I chosen to have all oil and filter changes at the stealer, I would have received goodwill. Not to mention, the savings I had by diy using oil and filter of my choice, knowing it's done right each and every time.
Bottom line as topic says, a failed Honda design here. Chalk it up to a life lesson.
