NHTSA Complaint #11706860 — 2018 HONDA ACCORD

The head gasket of my 2018 Honda Accord, 1.5L turbo engine blew, allowing coolant to leak and pool into cylinder 3 of the engine. The engine was inspected by a Honda dealership and confirmed the defect/failure. I don’t have the failed gasket, but do have images of the coolant running into the cylinder from the inspection. My family’s safety was put at risk as due to this failure the engine misfired and would no longer accelerate on two different instances. Once in a local 55 mph road where the car would get above 30 mph. The second was when my wife was driving in a 70 mph turnpike when the misfire happened. There were no warning lamps or indicators of the failure. The symptoms were duffle, which included worsening engine performance, gas mileage, rough idling, and jerking while driving due to poor combustion in the bad cylinder. They first appeared around 87,000 - 88,000 miles (within this last year - 2025).
