The Honda Corporation failed to issue a recall for defective engine blocks in Honda Civics, thereby not having to inform the consumer of a serious issue. I recently purchased a 2008 Honda Civic LX from a private individual. Within 3 weeks after purchasing the vehicle the engine temperature began to rise beyond normal operating temperature. Added almost 3 quarts of coolant to radiator and attempted to locate source of the leak but could not locate leak while vehicle was idling in driveway for over 45 minutes. | Then i began to do some research online in an attempt to pinpoint the source of the coolant leak. During my research I came across Honda Technical Bulletin 10-048. I then took the vehicle to my local Honda Service Department and instructed the service advisor to have the service department perform a coolant pressure test to locate source of coolant leak. Honda Service Department confirmed that the source of the leak was indeed hairline cracks on the exterior of the engine block but because the vehicle’s original purchase date was 5 months past the 10 waranty extension that Honda America refused to replace their defective engine block. Very dissappointed with the response from such a highly regarded automobile manufacturer.
