NHTSA Complaint #11446774 — 2007 HONDA CIVIC

My Civic was diagnosed with a cracked engine block, an issue known by Honda to be problematic, as they issued an extended warranty on the engines that ended in 2018. However, the extension has expired despite the fact that many Honda owners continue to experience this problem (see https://www.8thcivic.com/threads/documenting-cracked-engine-block-for-those-out-of-the-warranty-coverage.609546/page-7). This issue should be considered more serious than just an extended warranty, as an engine leaking coolant could easily overheat and cause serious problems on a road trip, especially in the part of the country I live in (Montana), where summers are hot and dry and wildfires are easily ignited. The Carfax report for the vehicle I own--which I purchased used in September 2021--suggested that this would be the perfect vehicle to buy, with a regular maintenance history and lower-than-usual mileage. No indication at all of an extended warranty or potential issues that I should be aware of. Fortunately a friend discovered the issue when he noticed coolant leaking when he changed a tire for me rather than me discovering it while driving to Colorado or Michigan to visit family, when the engine may have indeed leaked enough coolant without me noticing to cause serious problems. I am attaching the report from the mechanic who diagnosed the issue, which I sent to Honda to open a case for assistance with a repair (which they declined, citing the expiration of the extended warranty).
