I am filing a safety complaint regarding my 2018 Honda Accord equipped with the 1.5L turbocharged engine. The vehicle has experienced repeated engine-related failures despite multiple repair attempts by an authorized Honda dealership. Problems have included dashboard warning lights, engine misfires, loss of power, fuel odor, and suspected head gasket failure. Most concerning, on September 20, 2025, while exiting a highway with my child in the vehicle, the car suddenly lost power and all dashboard warning lights illuminated simultaneously. The vehicle became inoperable in traffic and required towing. This created a serious safety hazard and could have resulted in an accident. The vehicle has been returned to the dealership multiple times for the same or related issue on the following dates: • July 8, 2025 – mileage 80,099 • July 10, 2025 – mileage 80,101 • September 20, 2025 – mileage approximately 82,000 • October 27, 2025 – mileage 84,453 • October 28, 2025 – mileage 84,473 • April 16, 2026 – mileage 93,812 Repairs have included replacement of the high-pressure fuel pump and repeated diagnostic inspections, but the issue remains unresolved. I understand many owners of Honda vehicles equipped with the 1.5L turbocharged engine have reported similar problems involving head gasket failure, coolant intrusion, misfires, overheating, fuel system issues, and sudden loss of power. I am concerned this defect presents a significant safety risk.

The car had a strong smell of fuel in cabin when starting on various occassions. The car also temporarily stalled and lost power when coming to a corner turning and also three times when coming off the freeway. The car was always warmed up and in california during the warm weather. Dealer noted fuel smell in oil and increased oil level. Had oil changed and was told a fix was coming soon. Took car in to dealer months later for a recall, a bcm recall and again I told them that the oil smelled of fuel after 500 miles since oil change. Waiting for manager to call me back with update on fix. It is a 2018 honda accord 1.5 litr turbo. 26,000 miles on motor. I bought the car from the dealer in january 2020.

Purchased in may 2019. Currently < 50,000 miles. All service performed at honda dealership. Several weeks ago began to notice gasoline smell in the cabin while driving. Didn't think much of it, though it was coming from the outside/other vehicles. Check engine light came on last week. Took the vehicle to the dealership for service, was told the fuel injector needs to be replaced, cylinder 3 issue. Last resort was to do a fuel injector cleaning service, had that done. Two days later, while driving 70 MPH on the highway, the vehicle would no longer accelerate. Immediately pulled over without incident but could have been very bad. I am not convinced the fuel pump problems that required a recall for many 2018 accords with 2.0t engines are not also impacting 1.5t engines.

Driving on a major highway, 65 MPH with cruise control on. Suddenly, warning lights came on and vehicle abruptly and quickly decelerated from 65 to 20 MPH, forcing me to pull off the highway to the side of the road. There was a strong smell of gasoline in the car. I turned the engine off. Because of the potentially dangerous situation sitting on the side of the highway, I re-started the car a few minutes later and drove to the next exit a couple miles ahead at a reduce speed. I pulled into a parking lot and called for assistance. The honda dealer in orchard park, ny ,where the car was towed, told me that the oil level was extremely high, and changed my oil to bring it to a normal oil level. The dealer further told me that the because I drive short trips and the weather has been cold that is why gasoline is going into the oil and giving me engine trouble on my new car. My honda dealer in rochester, ny confirmed the same and said to drive my car a couple of times a week for a longer period of time to help avoid this issue. My driving habits as a student living on a small campus, in a cold area, are that of a few short drives a day to classes. I use my car primarily for driving myself home and to school which is a 2 hour drive. There is no recall for my honda accord, and both honda dealerships said that there have been similar problems with the honda cr-v & civic but they have never seen any issues with a honda accord. I want to make it clear that my new 2018 honda accord with 2220 miles has the same issue, and the engine malfunction on the highway scared the hell out of me and my family and I am very grateful I did not get hurt or my car malfunctioning did not cause an accident and cause injury to other drivers.

Oil is seeping from the top of the engine on the driver's side. I do not know the name of this component. Initially and shortly after we bought the car november 2018, there was the smell of oil/gas around the exterior of the car. I do not notice it now. I check the dipstick oil level routinely and had two dealerships check the oil level; one dealership changed the oil. However, the current oil level on the dip stick indicates that it is over-full and there is a slight smell of gasoline on the dipstick. The oil seems very thin (not viscous) and runs quickly off of the dipstick.

Upon completion of the driving the car, I will put the car into the garage. After 10-20 minutes has passed, I walk out to the garage and the whole garage smells like unburnt fuel. On occasion if the time between drives is short, the entire inside of the car will also smell like fuel. I have taken the car to the dealer 4 times so far, with no luck helping. Today will be the 5th time in the first 20000 miles. I put it as last week because that is what made me send it back to dealer yet again, but this has been on going for months.

Fuel dilution in motor oil. Bought the car new, checked dipstick, oil level is up past the upper line and smells of gas. Sent a sample of motor oil for testing and came back high for fuel % in oil. This is not acceptable for a brand new car with only 1700 miles! The car is driven an average of 40 miles a day, so short trips is not a factor. Changed oil using honda filter and mobil 1 0w-20 to spec, and after 500 miles, oil level is up and smells of gas again. Attached is the used oil analysis at 1700 miles.
