NHTSA Complaint #11551637 — 2007 HONDA CIVIC

Cracked engine block to the front, lower passenger sideof the engine block behind of the catalytic converter. Issue unknowingly began when commuting on the freeway until car was left parked for an hour. Coolant had puddled under the car in that time and upon inspection noted dried blue coolant sprayed all across the under side of the car originating from the cracked area indicating I was still driving when the leak started without any warnings. Given how much coolant leaked over that hour, this could cause rapid engine overheat while driving if the leak remains unknown. After some research, Honda knew about this manufacturing defect for a number of years and issued an extended warranty but those have all since expired, while engines are continuing to crack and fail.
