Failure Date: 10/20/2025

This is very serious while driving on the highway vehicle warning for engine temperature right after check engine came on. I almos crashed becuase the engine temperature close to limit asked to reduce the acceleration but how can I slow down in 2 lines fast highway on very dark night. This very, very unsafely and Honda should take this seriously if they claim safety is priority.

7 Engine And Engine Cooling problem of the 2021 Honda Accord

Failure Date: 10/17/2025

I hereby state that my 2021 Honda Accord has experienced major mechanical failures involving the transmission and head gasket. The vehicle began exhibiting mechanical issues including rough shifting, loss of power, and engine overheating. Upon inspection by a qualified automotive technician, it was determined that both the transmission and head gasket have failed prematurely. These failures have rendered the vehicle unsafe and inoperable, resulting in significant repair costs, loss of use, and financial hardship. The nature and timing of these failures suggest a possible manufacturing or design defect. This statement is submitted in support of a formal claim and potential legal action against the responsible parties for the defective condition of the vehicle.

8 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 10/13/2025

I have changed turbo, coil packs, fuel injectors, spark plugs, battery, fuel pump and my vehicle still give misfire in cylinder 3. Honda knows it’s a turbo and head gasket issue and will not do a recall on this for the vehicles. Horrible company. Will never buy another Honda.

9 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 10/11/2025

Head gasket for the second time.

10 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 10/10/2025

Head gasket problem. Coolant leaking into cylinder #2, head gasket needs replacing. The car is currently at a Honda dealership & they inspected/ confirmed that this was the issue. They expressed this was a common issue with this car. The first signs of issues happened while driving uphill on the freeway, the car started to “jump” when trying to accelerate. A couple of minutes later, the car would not accelerate while driving & the check engine light turned on. The second time, this happened much quicker. In a span of a couple of seconds, the car “jumped” while driving on the freeway again, and slowed down and would not accelerate, but various lights on the dash turned on this time. This is obviously very dangerous as a car suddenly decelerating while driving can cause the driver and others on the road to crash. There were no warning lights on prior to the first incident.

11 Engine And Engine Cooling problem of the 2020 Honda Accord

Failure Date: 10/04/2025

Was driving on the freeway approximately 70 mph on Saturday October 4th, when car goes into limp mode and throws a engine light on, leaving me stranded on the freeway. Another occurrence one week later on Saturday October 11th when car went into limp mode again driving around 35 mph in the city. Both cases I turned the car off and on and returned back to normal, come to find out with the dealer it is a blown head gasket and their is coolant leaking into cylinder 3. A blown headgasket!!!!! everyone is having these problems.

12 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 10/03/2025

While driving, my 2018 Honda Accord suddenly lost power and went into limp mode with no prior overheating or warning signs. The acceleration dropped instantly, and the vehicle nearly caused an accident as it seized up in traffic. Diagnostic scan showed a p0303 cylinder 3 misfire, which is consistent with head gasket failure. The issue has been widely reported among other Honda Accord owners with the same engine, and it appears to be a recurring defect. This failure is dangerous because the car can lose power abruptly at highway speeds or during normal driving, putting drivers and passengers at risk of collisions. The vehicle was properly maintained and had no prior indication of internal damage or overheating. The head gasket failure is sudden and mechanical, not caused by user neglect. It needs to be investigated as a manufacturer defect before it leads to serious accidents or injuries.

15 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 10/01/2025

Driving on highway, check engine light went on and car lost all power would not go over 5 mph scared for my life as I was almost hit by other vehicles traveling at hi rates of speed . I managed to get the car to the shoulder. I turned the car off and restarted, and the car went back to operating normal. Car was checked by a friend who is a mechanic, and he told me there were codes for misfires after checking all the issues that could cause that type of problem he informed me that a pressure test on the coolant system revealed a blown head gasket which allowed coolant to leak in the cylinders causing miss fires due to the anti freeze extinguishing the spark of the spark plugs. I researched this matter and it's see to be a very common problem with many Hondas with the 1. 5 engine.

16 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 10/01/2025

100k miles on our Honda when there showed misfire in cylinder 3 kept coming up. Changed the coils and spark plugs. The car lost power on the freeway almost resulting in a collision. Had the car towed to Honda dealership where they quoted us 4800$ for a head gasket. Honda knows what they’ve done. I will never in my life buy another Honda.

19 Engine And Engine Cooling problem of the 2019 Honda Accord

Failure Date: 09/25/2025

In the past 2 months my car starting having rough idle issues. As recommended by the dealership, I replaced the head gasket as they said it was leaking coolant into the cylinder causing the rough idle. Almost immediately after paying for this, the dashboard lit up like a christmas tree with multiple warnings and the car went into limp mode, lost acceleration and would have been extremely dangerous had we been on the interstate or multi lane road. Took it back to the dealership, ran another diagnostic and determined the fuel injectors needed to be replaced. These repairs cost over $5,000. Recalls have already been put in place for models around this one and Honda should acknowledge these problems as it is wide spread.

20 Engine And Engine Cooling problem of the 2019 Honda Accord

Failure Date: 09/22/2025

My vehicle’s fuel delivery system failed after a recall repair. The in-tank fuel pump was replaced under recall by the dealer, even though I had no drivability complaints, no warning lights, and a full inspection that day confirmed no issues with my vehicle. Immediately after the recall pump replacement, the vehicle developed drivability problems including sputtering, hesitation, and failure to start. On one occasion, the underside of the car overheated and exhaust fumes, including carbon monoxide, entered the cabin. The interior filled with heat and fumes, I became lightheaded, dizzy, and shaky, and nearly lost consciousness while driving. My dog, who was with me, vomited and panted heavily from the exposure. I had to pull over and exit the vehicle immediately. This incident occurred only after the recall pump was replaced and points to faulty installation or malfunction of the recall component, which disrupted the fuel system and caused improper combustion and exhaust handling. On another occasion, the vehicle stalled in the middle of an intersection, leaving me at serious risk of being hit by cross traffic. The car now shows a high-pressure fuel pump fault. Although the in-tank pump and the high-pressure pump are in different locations, they are part of the same system: the in-tank pump supplies steady fuel volume and pressure directly to the high-pressure pump. If the in-tank pump is defective, mis-installed, or inconsistent, it causes the high-pressure pump to fail. This made my vehicle unsafe to operate, placing me, my passengers, and other drivers at risk. The problem has been confirmed by the dealership, which documented a high-pressure fuel pump fault, and reviewed by Honda corporate. Components and service records are available for inspection. There were no warning lamps, messages, or drivability issues prior to the recall service, all symptoms appeared immediately afterward.

21 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 09/20/2025

My 2018 Honda Accord at only 63,000 started to lose power and all the emergency lights went on. Diagnosed as a misfire and now requires a new head gasket. This was told to me by the dealer to be a well known problem with the 1. 5 t 2018 Honda Accord.

22 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 09/19/2025

I lost power to the vehicle in the middle of the road as I was accelerating uphill approaching a stop light getting ready to get on the on ramp to the highway. All the dashboard lights came on and the check engine light was flashing. I had to let my car idle it's way to the side of the road. I took my car to a Honda dealership. Diagnosis showed cylinder 3 misfire, coolant leaking into cylinder 3 indicating a blown head gasket. A couple of weeks before the loss of power to the vehicle, my car was sputtering and jerking when accelerating. It would get really bad when accelerating uphill.

23 Engine And Engine Cooling problem of the 2019 Honda Accord

Failure Date: 09/19/2025

I have taken my car to the Honda dealership on multiple occasions because my car has stopped accelerating while driving on the interstate. The car will flash the check engine light and completely stop accelerating while driving. I was first told it was the fuel pump that was recalled and waiting over a year on the recalled part and multiple times breaking down while driving they finally replaced the part. After the dealership replaced fuel pump I continued to have problems unfortunately happening more often and worse than before replacing the fuel pump. I was then told my car was misfiring and needing a tune up which would involve replacing all four coil packs and spark plugs. I replaced all of these recommended parts with no resolution to my problem. I have since be told by the dealership my car needs all four fuel injectors replaced after running the diagnostic tests. After doing research it seems to be a common problem with this make and model car. I can’t believe with as many cars with this same issue and the safety issues with completely stalling in the middle of traffic there are no recalls on these cars.

28 Engine And Engine Cooling problem of the 2024 Honda Accord

Failure Date: 09/17/2025

Wiring harness failed randomly at 42,000 with no damage to the harness, engine, or vehicle itself. Without the wiring harness the engine does not run properly and shakes violently, causing the car to lose power. This happened with no prior warnings, problems, or damage. Additionally the steering rack seems “loose” and changes direction quite quickly when hitting a pothole or uneven roads even at lower speeds. I have to make sure I constantly have a firm grip on the wheel so no sudden unexpected direction changes occur due to imperfections in the road.

29 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 09/15/2025

Engine head gasket failed allowing a coolant leakage, which damaged spark plugs and fuel injectors. There is video evidence of this failure provided by the dealership service center. Link to video: [xxx] this occurred at approximately 70k mileage, which is far earlier than a failure like this would be reasonably foreseeable. I see many, many, others online who have had the same failure on my model of car at similar (early) mileages of 70k-90k. My car lost power on the highway, leading to a dangerous driving condition for myself an others. There was no obvious warnings that this would occur. After pulling over and turning off then turning on the car again, the car was intermittently drivable, with clear engine trouble. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

32 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 09/13/2025

This car is known for its faulty engine. The head gasket tends to blow as early as 40k miles, plenty of people have had this problem and yet there is no recall for the engine or a fix. I was driving on the highway and I was speeding up to merge into traffic and my check engine light started to flash and my car went into limp mode on the highway luckily there wasn't a lot of traffic and I got the chance to pull over and restart my car. I looked online and plenty of people were experiencing this same problem they all had the same answer as well, a blown head gasket. I'm just wondering if someone has to pass away before this gets fixed.

33 Engine And Engine Cooling problem of the 2019 Honda Accord

Failure Date: 09/13/2025

My head gasket blew in my car while driving on a highway, causing the car to jerk and completely die on me and it was unable to be restarted. My cylinder walls are scored and my head is completely ruined. It was a safety risk due to me being in the middle of the highway and having no control of the car as it died. It is also the second time the head gasket has blown since having the vehicle less than 3 years.

34 Engine And Engine Cooling problem of the 2025 Honda Accord

Failure Date: 09/13/2025

Vehicle makes rattling noises while accelerating similar to a diesel engine also rough transitions between ev mode and gas mode also when you press the charge button the engine makes a very noticeable jerk once it’s on ,Honda does not want to fix my issue and says everything is normal and cannot replicate the issue!! there is clearly something wrong I suspect fuel injector issues as others reported but dealer does not want to take accountability.

35 Engine And Engine Cooling problem of the 2018 Honda Accord

Failure Date: 09/12/2025

My 2018 Honda Accord ex is currently having fuel injector problems at 41,000 miles. Honda is trying to tell me that fuel injectors do not get affected by the recalled fuel pump. This is very silly because the fuel pump and fuel injectors work together. They want $1,800 to replace the fuel injectors at Honda. I already completed the recall on the fuel pump, and afterward, they told me my injector was running too rich and needed to be replaced for $1800. There are so many Honda 1. 5ts experiencing these same issues, and Honda does not want to do anything about it. I am currently taking my car to a local shop to get the fuel injectors replaced for $1,327. I believe I should be reimbursed since the fuel pump is what caused my fuel injectors to fail. Honda is trying to tell me that two fuel components of a car don’t correlate with each other? this isn’t fair, and I need to be reimbursed.
