NHTSA Complaint #11700645 — 2021 HONDA ACCORD

I am reporting a safety-related issue on my 2021 Honda Accord Hybrid involving a failure of the heating and climate control system. The vehicle is unable to produce heat or properly defrost the windshield, which significantly reduces visibility in cold weather. This directly impacts safe operation during winter conditions and should be considered a safety concern rather than a comfort issue. A Honda dealership diagnosed the problem as a heater core failure. The heater core itself is approximately $150, but the repair requires extensive disassembly and is estimated at nearly $2,000 due to labor. This type of failure should not occur on a vehicle this new. I recently purchased the car and do not believe this is normal wear or maintenance. Honda was contacted and denied goodwill assistance, stating they have no record of other complaints. I have since found similar reports from other Accord owners experiencing heating failures, particularly on hybrid models. This failure prevents windshield defogging and makes the vehicle unsafe for winter driving. I am documenting this issue with NHTSA so that the safety implications of heater failure on this model can be formally reviewed. I can provide the dealer diagnostic report, repair estimate, and Honda case number upon request.
