Engine And Engine Cooling Problems of Honda Accord - part 2

My Honda Accord keeps trying to turn off in the middle of the fwy and I know it’s due to the fuel pump, I have a misfire and all the warning lights came on. This is due to Honda having the fuel pump recalled that has damaged all the fuel injectors. It took them almost a year to get the recall parts and now myself and a ton of others are now having to pay for these fuel injectors to have a car that doesn't stall and die on the road. Honda should have taken care of this knowing it damaged the fuel injectors. Also issue with air bad supplemental issues.

2018 Honda Accord ex-l with the 2. 0l turbocharged engine. At approximately 113,000 miles the head gasket failed, allowing engine coolant to leak into cylinders 2 and 3. Symptoms included repeated cold-start engine misfires (diagnostic codes p0302, p0303, p0300), illuminated check-engine light, intermittent loss of power / limp mode, and gradual loss of coolant with no visible external leak. The failure was confirmed by an independent mechanic as a blown head gasket between cylinders 2 and 3. This matches a widely reported design defect in Honda's 1. 5l and 2. 0l turbocharged engines (2016–2022 Accord, civic, cr-v, Acura rdx/tlx) that is the subject of federal class-action litigation. The sudden power loss this defect can cause while driving presents a safety risk. Repair cost approximately $6,000, paid out of pocket, with no recall in effect. Requesting NHTSA investigate a potential design defect and recall.

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.

The first problems began in March 2026. No warning lamps turned on. My car began jabbing as I accelerated and a couple days after when I was breaking too. The first mechanic said it could be a coil but the problem didn’t stop after changing it. I then took it to Honda and they confirmed that it was a blown head gasket and that they were surprised no warning messages had appeared. I took it to empire automotive to get it fixed, I paid 5k to get it fixed. Three months after getting it fixed I am getting on the freeway and my car stops accelerating. The car behind me had to swerve on the side to avoid hitting me. I was able to move over to the side. Again no warning messages had shown up. I took it back to the mechanic and they confirmed the head gasket had blown out again.

Honda Accord 1. 5l engine had a blown head gasket at 94,000 miles. Local mechanic has advised that this engine has been an issue with blowing head gaskets early. Took it to dealership and they confirmed head gasket leaking. Was driving on highway and car went into limp mode and all the dash lights came on and car lost acceleration.

My vehicle started stalling and shaking right before all of the warning lights on my dashboard came on and the safety features stopped working (brake assist, brake hold etc). After checking, the spark plugs were all burnt out so I changed it along with the coil pack and this remedied the issue temporarily until it happened again a few weeks later. This time, I was on the highway going at around 55mph when the car suddenly started stalling and the speed dropped to 10mph. Luckily, I was in the right lane and had no cars behind me because it would've caused an accident. I pulled over to the side of the highway, shut the car off for 15 minutes and then took the nearest exit with my hazard lights on, going at around 10 mph. I took my car to the dealership and they stated that I need a new head gasket which will cost me from $5,000 to $9,000. After doing research, there are hundreds of other Honda's which are experiencing this same issue. Currently, the condition is worsening as the car is shaking abruptly and I am not able to drive over 30mph. I also experienced a burning smell.

Coolant leaks into engine components, causing overheating, loss of power, and contamination of engine oil. Head gasket failed.

There were no warning lamps or messages prior to the failure. My family was out of town, when the fire occurred. However, the neighbors were home and their home also sustained some damage. My home was a total loss. On June 16, 2026 I received a call while out of town that my home was on fire and it was a total loss. Statements from the neighbors and fire marshal were that the garage was on fire and then spread to the rest of the home. The only thing in the garage that could have started the fire was my hybrid vehicle.

The car suddenly started to miss fire and lose power. This puts the driver and others in dangerous situations. If it happens when pulling out into traffic and the car misfired it could cause a serious crash. Honda service diagnosed that a blown head gasket causes coolant to leak into the cylinders, leading to engine misfires and a sudden loss of motive power at highway speeds. This issue is well documented on 2016 to 2022 Honda Accords. There are many documented cases of this exact premature failure. Honda is aware of this issue and has awarded some owners goodwill repair when outside of warranty. There is currently ongoing litigation because of the 10s of thousands of head gasket failures. My car has 75k miles and went out of warranty at 60k miles. My goodwill request was denied by local regional Honda rep but I elevated the request to corporate Honda and currently waiting on their response.

Known issue by Honda; 2018 Honda Accord sport, 1. 5l 6s manual transmission. Head gasket is blown, alongside failed fuel injectors for the 1. 5l motor. Vehicle has been misfiring. Not accelerating properly which is causing the vehicle to suddenly slow down in traffic, promting potential vause for accidents. Almost was involved in 2 accidents due to the sudden and complete loss of power at a decent rate of speed. Cel came on twice, which then disappeared and the vehicle acted "normal" until acceleration. Took vehicle to a Honda dealer and was told it was the "spark plugs and the coil packs", even after explaining to them that there was engine oil on the piston heads, and low coolant. Left the dealer upset that they barely did any diagnostic work, and took it to an independant shop that actually completed a proper diagnostic performance, and confirmed the head gasket is leaking coolant, and the fuel injectors are failing. Known common issue that Honda is failing to recognize.

While driving the vehicle stops accelerating, it seems to have lost power and will not accelerate. It gives an error that says "check charge system" the vehicle has stopped accelerating while driving, most recently on the freeway while driving the car would not accelerate and I had to navigate to the side of the road while the car lost speed, causing hazardous conditions for myself, my children that were in the vehicle, and others around me. The car has been towed multiple times because of the same issue. I have attempted to have this vehicle repaired numerous times, at this point the mechanic has said that it is an issue with the vehicle itself and has suggested to contact Honda directly. The vehicle has only been worked on by independent mechanics. The lights on the dash blink while it occurs but there doesn't seem to be any forewarning that the issue will occur. It happens at random, no specific rate of speed. The issues started happening about a year ago, I have replaced the battery multiple times and have paid for other repairs but have not resolved the issue.

The contact owns a 2018 Honda Accord. The contact stated that the vehicle was taken to the dealer for an oil change; however, after leaving the dealer, the vehicle stalled while driving 25 mph. The contact returned to the dealer and notified the dealer of the issue. The contact was informed that the vehicle had experienced head gasket failure and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure, and the contact was referred to the NHTSA hotline for additional assistance. The failure mileage was 99,000.

I received a warning light indicating my car was reaching maximum internal temperature. I immediately shut off the car, then took it to the Honda service center the next morning. They did an inspection and determined there is a leak in my head gasket at cylinder 3. There were no warnings prior to the time of failure. I had recently had my coolant flushed as part of general maintenance and I never missed an oil change. Vehicle inspections at the Honda service center regularly showed no issues.

I am writing to file a complaint regarding a serious issue with my Honda vehicle involving the turbocharger system. The turbocharger appears to be failing, causing a significant reduction in vehicle speed and performance while driving. During operation, the vehicle suddenly loses power and acceleration, making it difficult and potentially unsafe to maintain normal traffic speeds. At the same time, multiple warning lights illuminate on the dashboard, indicating possible engine and system malfunctions. This issue creates a serious safety concern for both myself and other drivers, as the vehicle may unexpectedly slow down while traveling on highways or busy roadways. The condition has negatively impacted the reliability and dependability of my vehicle. I am requesting that Honda investigate this matter promptly and provide assistance in diagnosing and correcting the issue. If this problem is related to a known defect, recall, service bulletin, or warranty extension, I would appreciate being informed immediately.

I own a 208 Honda Accord sport 1. 5l turbo that I purchased new. At approximately 69,000 miles, the vehicle experienced a cylinder head gasket failure, allowing coolant to enter the engine. The vehicle was diagnosed by Honda dealership, which recommended replacing the cylinder head gasket, cylinder head bolts and spark plug at an estimated cost $6,500. Prior to this failure, the vehicle began overheating and warning indicators appeared. The failure resulted in the vehicle becoming unsafe to operate because continued driving could have caused severe engine damage or an unexpected loss of power. The vehicle has been maintained throughout my ownership and I have retained maintenance records. I was also informed by Honda dealership that they have seen multiple 2018 Honda Accords 1. 5l turbo vehicles come in with the same head gasket issue. Based in my experience, I believe this may represent a recurring defect affecting this model.

Multiple misfires, dealer says blown head gasket after replacing coil and spark plugs. Quoted 6,500. Car still runs is not running hot no exhaust smoking. Told this is common issue after fuel pump was on recall and replaced. After fuel pump replaced car smelled of gas for 3 weeks.

Dashboard displayed multiple messages and icons/warnings. Steering wheel locked, acceleration was low, barely any power to drive. Engine running rough condition. Obd2 scanner p0302 and p0303 detected. Engine misfire. Honda dealership diagnosis car. Main concerns include a head gasket blown or crack. Coolant leaking into cylinder 2 and 3. Tie rod cracked. Pressure test low. The vehicle has no prior history of cylinder head removal or head gasket replacement. Vehicle has been properly maintained through consistent oil changes.

The contact owns a 2024 Honda Accord. The contact stated that while driving 50 mph, the instrument cluster lights illuminated. The message “emissions system power reduced – see dealer” was displayed. An unknown transmission message was displayed. The engine was not working properly. The message "pull over and turn off vehicle" was displayed. The contact pulled over for 10 minutes, restarted the vehicle, and continued to drive to the residence. The local dealer was contacted, and a service appointment was scheduled. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 75,000.

While driving my 2019 Honda Accord hybrid at highway speed, the engine suddenly suffered catastrophic failure. The engine block ruptured, leaving a large visible hole with internal engine components exposed. Oil was expelled into the engine bay and ignited/burned briefly. This occurred without prior warning at highway speed and created a sudden loss-of-propulsion hazard. The vehicle has approximately 48,500 miles and has had regular on-time maintenance via Honda dealership. No warnings or other symptoms were active prior to engine rupture event. Fire dept & nys police arrived on scene prior to being towed. The vehicle is currently preserved at sussex Honda dealer for inspection and awaiting diagnosis.

Blown head gasket. Engine lost power and forced me to pull over. The problem is well documented with this generation of Honda 1. 5t engines, Honda dealership confirmed problem and second opinion from independent shop also confirmed, citing they had another Honda with the same 1. 5t engine with the same blown head gasket issue. No clear warnings prior to event, all the dashboard lights flashed on when car lost power.

While driving, my vehicle experienced a sudden engine malfunction consistent with a failed head gasket. The engine began misfiring, shaking, and losing power, and the check engine light began flashing. The vehicle became unsafe to operate. The failed component is the engine head gasket, and the vehicle is available for inspection upon request. The sudden loss of engine performance created a serious safety concern. I was driving on a public roadway when the engine began misfiring and losing power, making it difficult to safely maintain speed and operate the vehicle. A sudden loss of power while driving increases the risk of being rear-ended or becoming involved in a collision, particularly in traffic, while merging, or at highway speeds. The vehicle was inspected and diagnosed by an authorized Honda dealership, which confirmed the head gasket failure. I also spoke with independent mechanics who were immediately familiar with this type of failure on Honda's 1. 5l turbocharged engines. Although Honda diagnosed the problem, my request for goodwill assistance was denied because the vehicle was outside the warranty period. The vehicle has been inspected by Honda and is available for further inspection if requested. It has not been inspected by law enforcement or my insurance company because no accident occurred. As the condition progressed, the engine developed a rough idle and intermittent misfires. Eventually, the check engine light began flashing, and the engine began shaking and losing power while I was driving. These warning signs escalated into a condition that I believe presented a significant safety risk. I am submitting this complaint because an engine that suddenly loses power while being driven poses a serious safety hazard to both the driver and others on the road. I respectfully request that the NHTSA investigate whether this represents a recurring safety-related issue affecting Honda vehicles equipped with the 1. 5l turbocharged engine.

2018 - 2022 models of the Honda Accord sport are known to have a issue with the head gasket overheating and cracking causing cylinder miss fires and engine issue. Honda has refused to acknowledge the issue as a recall and my car recently suffered the same issue.

The engine failed catastrophically. White smoke out of the exhaust at 145,000 miles. Dealer checked out the car and they initially though it was a head gasket failure. After taking the engine head off, it turns out it was a 'structural defect' (verbatim words from the mechanic), which was a divot in the engine block. The head gasket was in great shape. Therefore, I needed a 'new' used engine (at $9k) instead of a head gasket replacement (at $4k). A search on the internet shows that forums (driveaccord. Net, facebook groups) shows that many Honda Accord owners have similar head gasket failures. I contacted Honda USA and they said there's no recall so I won't get reimbursed.

Blown head gasket between cylinders 2 and 3 at only 100k miles. Leaking coolant and causing overheating.

While driving, my check engine light cam on suddenly, along with my entire dashboard lighting up with all kinds of warning lights. At that moment, the engine ran very rough while attempting to push the accelerator pedal to maneuver out of traffic, feeling like there was no power. With that, I also noticed the temperature gauge start to increase towards the hot limit, though there was no venting of steam from the radiator. I stopped my car on the side, turned the car off, and waited u til it cooled down before attempting to start it again. When restart after a period of time, I noticed what smelled like coolant coming from the exhaust. I have not been able to bring the vehicle to a mechanic to diagnose the issue just yet.

I turned my car on and about 10 warning lights came on the car- drove it straight to the dealer where they told me the head gasket was leaking into cylinder 3 gave me an estimate of over 5k. Every mechanic I have called has told me how unusual it is for a car not very old and not over heating to have a blown gasket head. I was looking online and have seen how common the blown gasket head was on Honda Accord models 1. 5 from 2018-2022. There is nothing in the car no over heating no damage though could have cause it to leak unless it wasn’t properly installed which seeing how common it is might be the case. And how unusual it is According to many mechanics. The car has 115000 miles but has never had an issue and I wasn’t driving or anything when the warning lights came on.

My engine is overheating, cannot drive the car at all. There is coolant loss and leaking into the cylinder. It is rough running and misfires: no matter when I start the Honda whether a fold start or not it is chunky and wants to give out. There is loss of power which makes my car feel sluggish and is very dangerous as I’m driving myself, children and family on the freeways of st. Louis. I have never had any other issue and maintained the maintenance on the car. Honda dealership wants 6k to start fixing it. Could be more after they get into it.

I am filing a complaint regarding the premature head gasket failure on my 2021 Honda Accord, which failed on may 28, 2026, with only 89,000 miles on the vehicle. A head gasket is a critical engine component that should last well beyond 89,000 miles under normal driving conditions and proper maintenance. I purchased this vehicle because of Honda's reputation for reliability and longevity, and I am extremely disappointed to experience such a major engine failure at this mileage. After researching the issue, I found numerous reports from other Honda Accord owners experiencing similar head gasket failures, particularly in newer models equipped with the 1. 5l turbocharged engine. Many owners report engine misfires, coolant loss, overheating, and costly repairs at relatively low mileage. This suggests there may be a broader issue affecting these vehicles rather than normal wear and tear. My vehicle has been properly maintained, and I did not expect to face a repair of this magnitude before reaching 100,000 miles. The cost of replacing a failed head gasket is substantial and places an unfair financial burden on owners who reasonably expect Honda vehicles to provide dependable service. I respectfully request that Honda review this matter, investigate the growing number of similar complaints, and provide assistance with repair costs. I believe Honda should stand behind its products and support customers who experience premature component failures. Thank you for your attention to this complaint. I look forward to a prompt response and a fair resolution.

Engine began running rough and warning lights came on the dash indicating multiple issues and the engine light. Brought it to Honda and the tech diagnosed a head gasket failure. Honda recommended a head gasket repair. Car only has 137,000 miles on it.

A loss of power while driving on the freeway created a dangerous situation and nearly caused an accident. The issue was diagnosed by the Honda dealer as a misfire of the 3rd cylinder due to a head gasket failure and a fuel injector issue. No other symptoms were detected as this appeared suddenly at the worst possible time.

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.

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.

While driving on the highway at approximately 65 mph with my child in the vehicle during rush-hour on may 21, 2026, my 2018 Honda Accord hybrid touring (105,746 miles) suddenly dropped speed, and began backfiring and stopped responding to the gas pedal. The check engine light flashed and the vehicle ran rough. I activated emergency flashers and drove slowly to the shoulder. Sunnyvale Honda (sunnyvale, CA) diagnosed coolant intrusion into one of the cylinders and head gasket failure. The vehicle had never overheated and showed no prior warning signs. All maintenance was performed at Honda dealerships per the maintenance minder schedule. The dealership performed a head gasket repair costing $7,500+ out of pocket. On the first highway drive after pickup, again with my children in the vehicle, the identical failure occurred: backfiring, complete loss of throttle response, vehicle unable to exceed 48 mph with the accelerator fully depressed. The repair did not resolve the defect. The vehicle is currently back at the dealership for further investigation. This failure created an immediate safety hazard on both occasions: sudden loss of speed on highway with no warning. Honda customer service denied goodwill assistance. I am aware of numerous similar complaints involving coolant leak and head gasket failure on 2018-2022 Accord including complaints documenting the same failure on the Accord hybrid 2. 0l engine. Nhtsa should investigate this as a potential safety-related defect affecting multiple Honda engine variants.

While driving my vehicle suddenly would not accelerate above 20 mph and warning lights all over the dash lit up (check engine, abs brake system, adaptive cruise control, vehicle stability, power steering, hill assist, and brake hold). I took it for a diagnostic, it gave a code for cylinder 3 misfire. I got a tune up the next day along with a fuel system cleaning just to be safe. After about 35 miles of driving I had the same issue 2 days after the tune up, this time no warning lights. I took it back to the shop and this time the spark plug in cylinder 4 was bad. I believe I am at the beginning of what many others have complained about with these same symptoms. This problem makes operation of my vehicle unsafe and uncertain, at any time this issue can kick in and now you are limping along at 20 mph while cars zoom all around you. While trying to get the vehicle to the shop I created traffic buildups and was almost hit multiple times due to the vehicles diminished acceleration.

While on the highway, going approximately 60-65mph, lights on my dashboard suddenly lit up and turned right back off as my car began to decelerate on its own. After I was able to get my car off to the side of the highway, I had to have it towed home as it was inoperable. I had it towed to my preferred auto shop and they discovered the engine had failed at only 84,000 miles. The total cost was approximately $8,600. After a bit of research, it seems this is a known issue for this engine model from Honda and nothing has come of it so far.
