In 2018 Honda Accord with the 1.5-liter, four-cylinder turbo engine that had a head gasket fail at 110k miles which has been diagnosed and confirmed by local Honda dealer with misfire codes/counts on cylinder 1 due to coolant leaking inside cylinder 1 and 2 due to this bad head gasket. Due to the bad head gasket and coolant leaking into cylinders, this caused the fuel injectors to clog and fail. Creating rough idling and poor engine performance, which could cause car to stall at any point, creating a safety concern for those in the car if stalled/stuck on public roads. Additional discovery information found here of Honda America acknowledging the defect and encouraging dealerships to report this issue with incentives.

The car misfires very badly. I have changed the fuel injectors, fuel pump, spark plugs and the ignition coils to no avail. Also, car randomly showed to be overheating one day, got home and checked and my coolant level had dropped dramatically very quickly. The car has since been diagnosed with a bad head gasket.

All alarms are on. Breaks adaptive cruise control hill assist and all other alarms. Taken in to 2 Honda deals and serval mechanics they cannot figure out what’s wrong with it. About once a month all the alarms will clear while driving and the car sensors will start making the car drive odd. Have to fight the steering wheel to keep it straight and wheels will independently break, thinking it’s sliding but it’s not. Extremely dangerous on snowy road or wet roads.

I was driving and the engine light started flashing, the car started to hesitate and would not go over 20 mph. I took it to the Honda dealership in Frisco, TX and they diagnosed the issue using Boroscope and recommended Head Gasket replacement with spark plugs due to plugs being fouled from coolant leaking into combustion chamber.

On June 13, 2025, the fuel pump was replaced due to a recall. After the fuel pump was replaced and, in particular, after reading the Honda forums for this car, all the warning lights in the instrument cluster came on. After my mechanic checked my car and, with his knowledge of this type of vehicle, he recommended replacing the fuel injectors at 86,000 miles. Honda recommends replacing the fuel injectors at 1000 k. In the forums, this is what owners of the 2018 Honda Accord are doing.

This car has a faulty motor that Honda is well aware of. The head gaskets crack, and the antifreeze leaks into the cylinder. Specifically, Cylinder 3. My car is at the dealership, and the repairs are 6500. They refuse to acknowledge this problem and currently have a class action lawsuit because of this very issue. I need a car because I am a full-time student.

A supplemental restraint warning came on dashboard, I noticed other accord owners are experiencing the same this light has to do with possibly airbags or seatbelts making it possibly unsafe to drive.
