2018 HONDA ACCORD Complaints

The head gasket failed on my 2018 Honda Accord 2.0T at 81,000 miles due to weak factory head bolts stretching under turbo boost, causing cooling system over-pressurization and risk of engine stalling/overheating

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.

1) The cylinder head gasket was “blown” and leaking coolant into cylinder 2. 2) As I was merging into traffic, my vehicle suddenly lost power and entered limp mode and the check engine light began flashing. 3) Yes, serviced at the dealer and confirmed 4) Inspected by dealer 5) No

My car is having issues with the head gasket. My car check engine lights came on like a lit Christmas tree with many warnings (Emission System, Brake System, Departure, Uphill and many other more). I took my car into Capital Honda for a diagnostic on 5/4/26 and they informed that it was the head gasket that needs to be replaced. They are charging me $6000 to repair and do not have the funds to fix. Also I contacted Honda Corporate since I read on google that I may qualify for the goodwill program and they said I didn’t qualify since I did not purchase warranty on the vehicle when I got it. I also do see that there is a lawsuit in place for this. I’ve kept up with my car maintenance and never had an issue till now. The car is running rough and it’s shaking a lot. It’s also loosing coolant from the reservoir.

The engine stalled on the freeway. Has been having rough idles on cold start. Water gurgling/sloshing sounds coming from behind the dash on cold start. White, sweet smelling smoke periodically comes from the exhaust. Followed up with spark plug replacements. The vehicle still has all previous issues. Upon further inspection coolant reservoir is empty indicated a leak. No leaking fluid has been found. Suggests internal leaking. Issue is likely failing head gasket issue. Bissel v. American Honda Co. has been suing over this issue. The head gasket is allowing coolant into the cylinders mixing with fuel causing misfires and stalling the engine. Extremely dangerous. Likely to cause accidents.

While driving at highway speeds, the vehicle experienced a sudden jerking and a catastrophic loss of motive power (Limp Mode). Simultaneously, multiple safety systems failed, including the Collision Mitigation Braking System (CMBS), Adaptive Cruise Control, and Road Departure Mitigation. The vehicle became a road hazard in active traffic. A certified Honda dealership technician inspected the vehicle and confirmed a premature head gasket failure with coolant intrusion into cylinders 2 and 3. The engine is non-drivable and the vehicle is at 84,000 miles. Despite the documented nature of this design defect and its current litigation, American Honda Motor Co. has denied any assistance. The vehicle also has an open safety recall (24-009) for a fuel pump failure which presents identical safety symptoms.

I have a 2018 Honda Accord 1.5 sport and it had a premature head gasket failure at 78,880 miles. This is a well known issue with this engine. When I took the car in for repairs at Nalley Honda in Jonesboro Georgia the head mechanic at the location said these engines were not built right and he has seen an extreme amount of premature failures on this type of engine. He had been with Honda for 25 years and said he expected a recall on this and to keep my receipt on the repair. Hondas are usually known to be great cars and that has been my experience in the past, but this specific model does not pass expected reliability standards for a car! A $6K head gasket repair at 78K miles is not reasonable. I see that there is a class action lawsuit on this car for this same head gasket issue which shows that this is not a one off issue. Please issue a recall for this car and protect all the people who are on the hook for this ridiculously expensive repair at no fault of their own.

I have a Honda Accord Sport 2018 Engine 1.5L Turbo(1.5T) Mileage- 97,776 I am reporting a suspected premature head gasket failure which is affecting my vehicle and my mechanic told me this has been going on for a while now with the Accords around my year model. On cold starts, the engine shakes and idles roughly for about 10-20sec. There has been some jerking during acceleration and prior stalling incidents. I have also experienced a blinking check engine light which indicates an active misfire condition. The vehicle has been maintained regularly and have proof upon request. The anti-Freeze is leaking inside the cylinder 2 and 3 which is causing the misfires. The check engine light which is blinking is causing safety concern due to potential power loss and the risk of stalling while driving. This issue appears to be widespread among vehicles equipped with the 1.5T but also around the years of my vehicle. Honda dealership brought it to my attention during the last recall, and my personal mechanic (independent service) diagnosed my car and mention the same thing. I believe this is a manufacturing or design defect and request that NHTSA investigate this issue for potential recall or required manufacturer remedy

All lights on head dash are on , all components are not working properly or effected because of this. (Engine light brake light abs light tire light traction control light , sensors out all) while driving vechile reduces power does not operate randomly , have to pull over shut the car off and turn it back on. Has high vibrations lot of shaking, stauling. I have had it looked at with multiple shops and dealer . Everybody is playing a guessing game and can not pin point what exactly it is . Was told it was spark plugs and coils, alternator , fuel injectors. ALL have been repaired, and still have all lights on dash and still facing every problem listed after repairs. Been inspected by manufacturer. Say not been resolved was told if it wasn’t what was already fixed they don’t know and that this is very common right now . It first APRIL 2026 (3) times. May 2 times 2026

Car is constantly misfiring! I got my fuel injectors, plugs, coils all changed. Honda is now saying head gasket! Why isn’t this being recalled! I am seeing multiple people with the same head gasket issue.
