Filed Oct 10, 2025 · Engine · OH

The engine gasket failed, leaking coolant into Cylinder 3. This created misfires while the vehicle was driving, leading to unpredictable loss of power while driving. Eventually, the coolant purged unbeknownst to the driver and created overheating conditions while driving which could have led to complete engine failure on the road. This behavior was confirmed and reproduced by an independent shop, WenMac Repair, in Hardin County, Ohio. They replaced the spark plugs and coils, thinking the misfire was not necessarily related to the head gasket. The vehicle was then taken to Honda Development and Manufacturing of America, LLC's official repair center for Honda Associates attached to Honda's Marysville Auto Plant 10/1/25 and diagnosed by a Honda master technician. My fiance and I both directly work for Honda. It is currently having the head gasket replaced at a cost of $2,700.00 plus taxes. The vehicle is still in the shop. The failure was observed on vehicle first around 150,000 miles.
