No I dont have misunderstanding of the contract. There are things which have failed that I dont know about. If they check for it they may discover itThe traction battery and many other components are covered under a Federal Emissions Warranty for up to 10 years or 150K miles. Expect the dealer to charge a diagnostic fee if you request a battery capacity reading. Not sure what they charge to check the ELM.
You initially asked about what could be fixed proactively under the Honda Care contract and I attempted to explain to you that nothing would be fixed under warranty that hasn’t failed. You have a misunderstanding of the contract.
