I had a misfire on cylinder three. All vehicle lights came on. Vehicle had spark plugs and fuel injectors replaced. The problem persisted and the next code I received was a turbo burst under pressure code. So turbo and water pump were replaced. This made the problem worse because the new turbo made the head gasket leak. Now after paying $4000 in repairs I have to have the head gasket replaced for another $3000. This is a serious problem with these cars. Wish I never bought this piece of trash. I also replaced all break rotors pads and hoses. Terrible vehicle. Do not buy.

I own a 2018 Honda Accord equipped with the 1.5L turbocharged engine. At approximately 53,666 miles, the vehicle developed a rough idle, engine shaking during startup, intermittent check engine light, and a cylinder 1 misfire code (P0301). I took the vehicle to a Honda dealership for diagnosis. The dealership confirmed coolant intrusion into cylinder #1 after performing a cooling system pressure test and borescope inspection. The dealership determined that the engine has a failed head gasket and provided a repair estimate exceeding $6,000. The dealership advised that the vehicle should not be driven because coolant entering the cylinder can cause further engine damage, loss of power, engine stalling, overheating, or complete engine failure while driving. I believe this is a safety concern because the engine may misfire, lose power, or fail unexpectedly during vehicle operation. A major engine failure at only 53,666 miles is not consistent with normal wear and tear. I am submitting this complaint so that NHTSA can investigate potential defects involving coolant intrusion, head gasket failure, and cylinder misfires in Honda Accord vehicles equipped with the 1.5L turbocharged engine.

Blown head gasket between cylinders 2 and 3 at only 100k miles. Leaking coolant and causing overheating
Engine, Jun 10, 2026
I have been having issues with my check engine light being on for about 6 months now. Took the car to Honda to get it diagnosed and was told that I needed to get spark plugs, fuel injectors, and ignition coils. Got all of that changed and the issues still remains. Had an outside mechanic take a look and he specializes in Hondas and was told that it is the head gasket, and that would be the only way the issue will get resolved. After taking the car to Honda 2 times and paying for diagnosis with the issue still there. I was getting on the interstate and my car just started stalling, had to immediately pull over before getting hit. I was quoted $3000 to have the head gasket done. This obviously is an ongoing issue with my model Hondas, and I am already out of pocket $1000 with the issue not even being resolved.

Our mechanic, Buttons Auto in [XXX], diagnosed the loss of power, misfiring engine and anti freeze in the head cylnder # 3 with code P0304 and his conclusion was a blown head gasket. We took our car to the dealer, Mansfield Motor Group. Buttons also mentioned there was a pending class action suit against Honda for head gasket failure on our model with the1.5 liter motor. Mansfield Motor Group misdiagnosed the cars issue and charge us $2100 for the repair. A couple days after we got the car back the problems continued. We took it back to the dealer and they then diagnosed the isuue as head gasket failure. We spent another $4600 to fix the headgasket repair A total of $6100 we spent. We did file a claim with Honda, #XXX, which they denied both times. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I have owned my Honda Accord for under a year, puchased around 100k miles. My head gasket blew at 118k miles. There was no overheating of the engine or warning lights before hand, my car was idling after work and I turned it on and then I had about 5 different warning lights on. I find out that it was a cylinder 2 misfire and took it to Joyce Koons Honda for them to inform me of a head gasket failure and quoted me for around $7,000.

I am writing to formally lodge a complaint regarding a recurring issue I have experienced with the head gasket in my vehicle. I have owned several vehicles of this make and model, and I have observed a troubling pattern of blown head gaskets that has not been adequately addressed. Specifically, my current vehicle has suffered from this problem, resulting in significant inconvenience and additional repair costs. This issue appears to be prevalent across this year model as well, suggesting a potential design flaw or manufacturing defect that warrants further investigation. I respectfully someone to look into this matter to determine if a broader safety concern exists that needs to be addressed. Owners of vehicles affected by this issue may be at risk of serious engine damage and costly repairs. Thank you for your attention to this important issue. I look forward to your response.

Head gasket seal broken, leading to coolant leak into the engine causing misfire

Vehicle has only 48,037 miles. Diagnosed with bad cylinders 1 and 2 . Coolant also contaminated cylinders. I took vehicle to Autonation Honda Corpus Christi twice before the diagnosis. Vehicle was running rough. When first turn on engine especially when it is cold, there's a lot of engine shakes. Same as in when on idle. Technician said he could not duplicate problem but did not perform diagnostics. Vehicle was released. New coolant was added because Tech said it was low, brake fluids flushed, new sway bars were installed and wheel alignment performed. After a week, all engine lights came on while driving at 30 mph. Stopped the vehicle and get towed to the dealership. Diagnostics: blown head gasket, bad cylinders and needed new engine. Did a research and these were the Accord problems that were never addressed by Honda. Problems also included Turbos and Fuel injectors.

I have owned a handful of Honda's and never had an issue with them. I own a 2018 Honda Accord Sport and when driving it all the lights on the dashboard lit up. The car left like it was stalling and wouldnt go past 2nd gear. I was almost rear ended by a car and had my 2 granddaughters ages [XXX] and [XXX] in the back seat. I took it to Honda dealership and they said the turbocharger needed replacing as well as a head gasket. My sister inlaw also owns a Honda like mine but hers is a 2021 and the same issue happen to her. It seems like this is an on going problem that Honda needs to address or assist customers with purchasing. It is not safe to continue to keep these cars with these issues on the road.

I own a 2018 Honda Accord with approximately 108,000 miles. My vehicle has experienced ongoing fuel system and drivability issues connected to the fuel pump recall. It took over two years for Honda to complete the recall repair due to delays and lack of available parts. During that time, my vehicle developed additional issues including failed fuel injectors that required replacement. Even after those repairs, the vehicle continues going into limp mode, causing loss of power and creating a serious safety concern while driving. When I brought the vehicle to Honda for diagnosis, I was charged approximately $180 just to scan the vehicle and then quoted nearly $4,000 in additional repairs. In addition, my vehicle experiences what many Honda owners refer to as the “Christmas lights” issue, where multiple warning lights suddenly illuminate across the dashboard at the same time. This appears to be a widespread complaint among owners of this model and is often associated with ongoing fuel system, electrical, or sensor-related problems. Honda vehicles are marketed as reliable, yet many owners of this model have reported similar problems related to the fuel system, injectors, limp mode, and dashboard warning light failures after the recall issues. I believe the prolonged delay in addressing the recall contributed to further damage to my vehicle. Honda should take responsibility for these known issues and provide assistance to affected customers.
Engine, Fuel/propulsion system, May 27, 2026
While driving the car it went in to limp mode, restricting the ability to maintain normal driving. It did this because the head gasket needs to replaced because coolant is leaking into # 3 cylinder. My wife and others were put at risk when she had to pull over in an area that was unsafe according to a Summerville police officer who came to her aid and helped her get the car to a safe area.
Engine and engine cooling, May 26, 2026
The contact owns a 2018 Honda Accord. The contact stated that while driving the vehicle she noticed a power issue with the vehicle, thinking it had to do with the battery, the vehicle was misfiring. The vehicle was towed three times to the dealer, where it was diagnosed with a engine failure. The second tow was to a independent mechanic, and the third time the vehicle was taken to a dealer where it was diagnosed to have a engine gasket failure. The contact was informed that there was a coolant intrusion in cylinder #2. The contact was informed that the head gasket needed to be replaced. The vehicle was repaired. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 73,000.

The head gasket malfunctioned/ broke. It has been confirmed by the Honda dealer where I currently have my vehicle. There were no messages or symptoms prior to failure. My safety and others were put at risk because my vehicle began to turn off as I was driving up a hill with no warning. The vehicle began to decelerate.

Blown head gasket after multiple spark plug replacements for misfires.
Engine, May 18, 2026
I own a 2018 Honda Accord equipped with the 1.5L turbo engine. The vehicle is experiencing a head gasket failure consistent with numerous complaints reported by other Honda owners online and through NHTSA. My vehicle began showing symptoms including rough cold starts, engine misfires, loss of coolant without visible leaks, and reduced engine performance. Diagnostic testing indicated head gasket failure and coolant intrusion into the cylinders. The repair cost quoted to me is extremely expensive. This appears to be a widespread defect affecting 2018 Honda Accord 1.5T vehicles. Many owners are reporting similar failures at relatively low mileage, often involving cylinder misfires, overheating, coolant loss, and major engine damage. This issue creates a potential safety hazard because the vehicle can suddenly lose power, enter limp mode, or stall while driving. Honda should investigate this issue and provide assistance or recall coverage for affected vehicles. Consumers should not be responsible for major engine repairs caused by an apparent design or manufacturing defect. Vehicle: 2018 Honda Accord 1.5T
