Nice to hear a positive report.
May not be your issue, but a coolant leak, that cannot be found, possibly a small crack in block, that will worsen over time. Good you have your issue documented!
I purchased a new Honda car for wife, some years ago. About a year later, got a warranty bulletin, about coolant loss (no sign of leak), and design flaw, could cause block to crack, cause of coolant loss. They extended the warranty 10 additional years, to cover this issue (replace block), if it happened.
She didn't like the car, wanted SUV (grocery getter), so I sold car, with only 15K miles, to a relative for cheap, bought a new Ford Escape for her. The Honda owners happy, wife happy, all is good, for now!
