NHTSA Complaint #11472829 — 2008 HONDA CIVIC

While driving to work, the owner noticed a smoke coming out of the hood. The owner also noticed that engine temperature shot all the way up indicating that the engine might be overheating. Upon taking to a nearest auto shop, the owner was told that the engine block has a crack which is causing leak. Honda is aware of this issue and has provided extended warranty for 10 more years from the date of purchase. Unfortunately, the owner experienced cracked engine block issue 14 years after the date of purchase - 4 years after the extended warranty had expired. Upon calling the dealership, the owner was informed to file a claim with North America Honda. If Honda was aware of cracked engine block, why did it not replace engines in all affected models and trim levels?
