Engine And Engine Cooling Problems of Honda Accord - part 2

I own a 2019 Honda Accord equipped with the 1. 5l turbocharged engine. At approximately [142,000] miles, the vehicle began overheating and losing coolant with no visible external leaks. A Honda dealership diagnosed the vehicle with a blown head gasket caused by coolant intrusion into the engine. The repair cost quoted was several thousand dollars. Honda has denied goodwill assistance dates Dec 16, 2025 at 1:35pm, despite documented maintenance and the widespread nature of this issue in Honda 1. 5l turbo engines. This failure occurred under normal driving conditions and presents a safety concern due to sudden overheating, loss of engine power, and potential engine failure while driving. I believe this is a known design defect affecting multiple Honda vehicles, and Honda has failed to properly disclose or remedy the issue.

My fiance has a 2018 Honda Accord sport touring, this past Sunday he was giving me a ride and about 5 min of driving , after stopping for a red light , the light turned green he pushed the pedal and the car starting moving then all of a sudden warning lights were flashing , the engine light , remote not in car, oil light, air bag , low tire, etc. There was alot at the same time when the warning lights came on as he pushed the gas pedal the car stopped accelerating, and he said he had no power in the pedal ,there was heavy traffic, a car could of rear ended us but he was able to put his hazards on and coast around the corner before the car stopped. He shut the car off and back on and it drove like normal again. I was scared of course and just wanted to go home. When we got home he remembered he still had his fathers obd scanner tool so he plugged it in the car and it showed no error codes. So that was really strange. He went to the store down the street the next day, but other then that he drives his work van and I have my own car. I was reading newsbreak and seen that Honda recalled only hybrid and newer years and thought thats odd I should let someone know this happen to his 2018 Accord , because im sure it has to happen to others. We didnt take it in or call the police , but this clearly could of caused a crash had he not remained calm and put his flashers, everything happened so fast. Im sure he would let you inspect it, he works during the morning. I have no clue why it did that and neither does he. Thank you for your time.

After vehicle got serviced an open recall for fuel pump, my car has been having issues. I know is related to the head gasket/fuel injections. My car has been great, monthly maintenance service up until I got that recall fixed. I now regret it getting repaired, but I had to, to be able to receive my dmv tags. I was driving about 45 mph and vehicle stopped accelerating will not speed over 20 mph and the check engine light turned on. Just got full transmission flush and oil change and this happened. I read many article online that this happens after this recall repair to the Accord 1. 5t ex2018.

I had just left my job in albany and was headed to the latham area, while merging into traffic on I-90 west my 2020 Honda Accord ex-l started to rattle and slow down, numerous lights illuminated simultaneously on my dashboard. I immediately pulled off the north shoulder and restarted my vehicle to no avail, the dashboard lights were still lit and my vehicles speed and steering were compromised. My safety was put at risk due to the immediate issues as previously described while in heavy traffic, I could have easily been involved in an accident due this issue. The system keeler Honda advised me that had failed was allegedly the head gasket leaking coolant into the engine by means of cylinder four. I was later informed by keeler that this is a common issue with the Accord 1. 5 l turbo engines. The problem has been verified by keeler Honda. There was no prior warning light on my dash that would have indicated there was an issue with my vehicle, the lights only all appeared once the incident had occurred.

I noticed random misfires months ago. I've replace my spark plug three times in 6 months. My coils are good, etc. It started getting worse about a month ago. It goes into limp mode and suddenly slows to 20 mph. Some days it won't start. The dash lights flash and the cars computer goes crazy it won't go over 20 mph. This is a widespread issue causing ppl to spend thousands and no fix in sight. Usually it hits between 15-90k miles. Twice I was on the interstate and it just slowed to 20 mph. I have had it at the dealer twice. They are clueless and can't do much without Honda stepping up. Honda needs to address this. My car was built in 2021 and somehow missed a major recall. It's putting stress on my catalytic converter and other parts that cost thousands to fix. I'm taking it in on Monday for the third time. If they can pinpoint it this time I'm afraid it might cost me thousands. It's a Honda and it shouldn't be having issues from 15k to 90k.

The fuel system on my 2022 Honda Accord malfunctioned and caused a sudden loss of power while my teenage son was driving. On 12/03/2025 at approximately 4:50 pm, the vehicle went into reduced-power (limp) mode while traveling in heavy highway traffic on a busy highway in a metro-area of >450,000 people. There was no shoulder available in which he could navigate onto. He was unable to accelerate and had to coast approximately one mile at low speed while many, many cars were driving around him during rush hour traffic , which created a dangerous situation with vehicles traveling at normal highway speeds. A Honda dealership has previously inspected and confirmed the problem. On 07/28/2025, the service center documented lean fuel condition, misfire codes (p0301, p0304), failed fuel-rail pressure, and injector-related faults. They recommended replacement of fuel-system components. The printed report and repair estimate are available for inspection upon request. Prior to the safety incident, the vehicle intermittently displayed symptoms such as hesitation during acceleration and irregular engine operation, but no permanent warning light stayed on. The failure has progressed over time and the same loss-of-power condition can recur at any time. This poses a risk because loss of propulsion in moving traffic can lead to a collision. The component issue has been confirmed by the Honda dealer, and documentation is attached. I am filing this report because the failure creates a safety hazard, has been reproduced by a local dealership, and has not been resolved. The repair show suggested I return to Honda for repair. Furthermore, during my research of this problem, I discovered tens of thousands of complaints from others experiencing this exact issue, including new low mileage vehicles. These complaints are available on all social media platforms and search engines, with each complaint indicating problems with the fuel injectors on engines using direct fuel injection.

Car started loosing power and fouling spark plugs 2 and 3. Took it to dealer shop and head gasket was bad.

My 2018 Honda Accord touring with a 1. 5l turbocharged engine began experiencing intermittent warning lights and error messages starting around 28,000 miles. I reported these issues to a Honda dealership on some visits however in most cases, the warnings were appearing and disappearing prior to my visit. However the error continued to appeared since then. At approximately 55,000 miles, multiple warning lights and error codes reappeared consistently. I took the vehicle to a Honda dealership for diagnosis and was informed that the issue may involve internal engine damage and that a full engine teardown would be required to determine the cause, at an estimated cost of approximately $2,000, before any actual repair could be identified. Seeking a second opinion, I took the vehicle to a different service location and completed a full tune-up at 63,000 including all standard maintenance expected at that mileage. Less than one week after the tune-up, the same warning lights and error codes returned. I took my car back to the same place where I had the tune-up completed and the same error codes appeared indicating the issue was not related to routine maintenance. I began to research online some common issues with my car, I became aware of a class action lawsuit (bissell v. American Honda motor CO. , inc. ) describing a known defect in Honda 1. 5l turbocharged engines where coolant leaks internally near the cylinder head, causing engine misfires, efficiency warnings, and internal engine damage. The symptoms described in the lawsuit closely match the ongoing issues with my vehicle. The repeated warning lights and potential for engine failure raise safety concerns. The issue has been reproducible and unresolved despite inspection and maintenance.

Emissions and engine light turned on which caused enginue to lose power and stall. Took car to dealership for diagnosis, and two codes related to failed fuel injectors and failed turbocharger. Tech said it is a known failure with this vehicle model, especially with the Honda turbo engine, so much so the warranty was increased from 100,000 miles to 150,000. Unfortunately my car was 15,000 miles over warranty and will be a costly bill. Online research yielded that tech was right, it is a known failure issue with this model but I missed the warranty extension. If this is a known issue by the manufacturer, should this not he a recall issue?.

My 2018 Honda Accord had coolant leaking in cylinder 3. Which caused the head gasket to blow. My car stopped on me in the middle of the hwy. I took my car to a shop down here to get fixed he couldn’t get it to run. All dashboard lights are on.

Head gasket caused by 1/4 inch head bolts and torqued to 50 lbs multiple people have filed a class action lawsuit regarding this and it’s affecting most Hondas with a 1. 5l engine. It caused misfiring and jerking it was inspected and confirmed by Honda service center that my head gasket was blown and I had purchased the car 12k miles ago.

While driving the car at approx 45mph on a busy roadway the vehicle suddenly accelerated heavily I tried applying the breaks but the pedal did not go down and had no affect of slowing the vehicle. I was forced to swerve around several vehicles to avoid a collision then just as suddenly the car returned to normal operation. The duration on the incident was approx 5 to 10 seconds. Very dangerous and very scary.

Engine,coolant system vehicle was cutting off in the middle of driving shaking and jerking.

My car had a head gasket failure. I lost power and control of the vehicle. Mistlin Honda in modesto confirmed it was a head gasket failure. No, all warning lamps came on at the sametime.

Started the car and the system was not booting up properly. Had to restart the car a few times for the system to boot up properly. Took 3 min to start up after restarting the car. No error codes just major lag and delay. Car was updated to the most current update and no new updates were available at the moment. Bluetooth also has a hard time connecting to mobile devices. Engine makes weird sound when accelerating on the highway in eco mode. Sometimes feels like misfires when accelerating. When entering the car from outside the seat sometimes does not adjust back to the original position stays at the extended position it does when getting out of the car. Requires me to adjust my seat consistently.

The contact's girlfriend owns a 2021 Honda Accord. The contact stated that while his girlfriend was driving at an undisclosed speed, the check engine warning light and several other unknown warning lights illuminated. Additionally, the contact stated that the engine was slightly misfiring while driving. An independent mechanic replaced the spark plugs and the ignition coils at the residence; however, the failure recurred 3 weeks later. The mechanic inspected the vehicle but could not determine the cause of the failure. The vehicle was taken to the dealer, where it was diagnosed with head gasket and fuel injector failure. The contact was provided an estimate for the repair. The vehicle was not repaired due to the cost. The manufacturer was not notified of the failure. The failure mileage was approximately 74,000.

Starts vehicle at cold start and notice right away engine turbulence, engine light flashing, lost some coolant and white smoke. Scan vehicle for codes, engine misfire #2.

Within 48 hours of taking possession, the vehicle suffered a blown head gasket, a catastrophic mechanical failure that constitutes a pre-existing latent defect—a serious condition that existed prior to the sale but was not disclosed to me. This defect renders the vehicle unsafe, inoperable, and unfit for its intended use. Claims that I did not purchase the optional 2-day cooling-off period or that the vehicle is covered under a manufacturer warranty are legally irrelevant. Under California civil code §§ 1791. 1 & 1792 (implied warranty of merchantability), a dealer is obligated to sell a vehicle that: 1. Is safe and operable at the time of sale 2. Is fit for ordinary driving purposes 3. Does not contain major latent defects that make the vehicle unsafe, inoperable, or unusable immediately after purchase the presence of a pre-existing latent defect is a direct violation of these provisions. The manufacturer warranty does not excuse the sale of a vehicle with a defect that existed at the time of purchase. I am therefore demanding, without delay: 1. Immediate rescission of the sales contract by raceway Nissan 2. Full refund of all funds paid, including deposits and trade-in credits 3. Coordination with valley strong credit union to fully rewind the auto loan, including principal, interest, fees, and any other charges 4. Confirmation that I will have no financial obligations related to this purchase once the rescission is completed.

Engine knock caused by oil dilution which is known manufacturing issues with my model of car.

I had to have the injectors replaced in April 2025. In November I was told a had a busted head gasket $5800. 00 to fix. Many Honda owners have had this problem. Honda customer services refuses to help.

I have a 2018 Honda Accord sport 1. 5 the issue started after getting my fuel pump replaced as part of the recall. While driving, all of the dashboard lights came on. Warning messages kept flashing on the dash. This car was driving perfectly fine before the fuel pump was replaced. When the codes are cleared, the car drives perfectly fine. The dashboard lights will periodically turn off but ultimately come back on and as a result, the car goes into limp mode. Coils, sparkplugs, breakers have been switched out and oil levels have been checked. When the car is scanned, the codes are reading a misfire with the coils but, the coils that are allegedly misfiring were just replaced. The car jerks while attempting to accelerate, and after a few miles, it goes into limp mode. I have tried every type of repair that has been suggested to me by the mechanic but the issues persist.

Defective turbocharged engine that is prone to overheating, head gasket failure and other problems. Design defect that causes engine coolant to leak into the cylinders.

I am the original owner of a 2019 Honda Accord hybrid that I have taken to envision Honda of milpitas. I have been consistently maintaining According to Honda’s recommended service schedule. No prior issues were noted. What happened to it is beyond normal wear and tear (failed head gasket). My car only had 78,731 miles on it when incident happened. I did not have any concerns with the vehicle until 11/12/2025 while driving on freeway. On 11/12/2025, while commuting home from work in the evening on the freeway, all warning lights came on (10/10 lights, including the check engine light). The vehicle could not exceed 50 mph on freeway, and began rumbling. The vehicle had no prior issues. I exited the freeway with hazard lights activated and contacted aaa for assistance. I took my car to envision Honda of milpitas the next day (11/13/2025) was informed that the head gasket was blown off. "cylinder leak down test done and found head gasket is blown on chamber 1 causing the coolant to leak inside the combustion chamber and causes cylinder to misfire. Recommend to perform teardown and inspection, head gasket replacement and re-check. " it was dangerous as I was not able to speed more than 50 mph in the freeway while other cars were going fast. I am currently pregnant and was scared.

Car has lost power or gone into "limp mode" while driving on multiple occasions. Car was never listed under the fuel pump recall but had all associated symptoms & problems. Had to have fuel pumps replaced in December 2023 due to car not starting because of faulty fuel pumps. Car has been properly maintenced since purchased brand new in February 2018. Currently around 121,000 miles. Car overheated this past summer, coolant seems to be leaking somewhere as just filled with coolant month ago and needed to refill with about quarter to refill to correct amount. Oil also seems to be having slow leakage problem somewhere within the engine as there is excessive oil on drip pan. Had all 4 spark plugs changed in March of 2025. Car has been going into limp mode and looses power for few seconds to minutes sometimes, almost causing multiple accidents while driving on highways. Pull over to shut off and give few minutes to restart and able to resume driving no warnings before this occurs. Randomly all dashboard lights light up 2 weeks ago and put car into limp mode, was driving on highway at high rate of speed (65mph) safety was compromised several times while this occurs. Engine seems create knocking sounds to known due to oil dilution problem. Cold weather seems to affect issues to onset more often. Also been having stalled or rough start ups in colder weather or when engine is not warmed up. Researching these issues seems to be that 2018 Honda Accords had known head gasket failure. This should become a class action lawsuit and also a recall.

My Accord v6 suffered catastrophic engine failure due to a bent connecting rod/seized bearing while driving at highway speeds. This is the exact same failure described in recall 23v-751 for other Honda v6 models.

On 5/12/2025 at 104,385 miles I brought my 2019 Accord hybrid touring into the local Honda dealer for recommended services that populated in the maintenance minder. It was a larger service plugs, coolant flush, brake fluid flush. Early November of 2025 at around 115k miles I had a warning message appear that said engine temperature critical. I checked the overflow reservoir and the coolant level was in operating range. The next day I got the same message, waited for the engine to cool. I took the radiator cap off and added about 1/2 gal of Honda coolant. I proceeded to monitor coolant levels occasionally adding coolant. There were no external coolant leaks. I dropped the vehicle off at wilde Honda on 12/8/2025 and after testing the system they indicated that there were coolant leaks in 3 of the 4 cylinders due to a failed head gasket. They also said the radiator might be leaking out of the top seam but couldn’t know for sure. The immediate failure of a head gasket could allow the vehicle to stall out while driving. I had the head gasket, timing chain and radiator replaced at 117,302 miles at a cost of $4200. Head gasket failure at this mileage and this brand is unheard of except when you look at the model years with this same design. There was a class action suit on the turbo charged models but more and more consumers are noticing failures with the non turbo hybrid engine as well. Honda is stating that there is no issue with the head gasket in the hybrid models.

This has happened out of the blue and randomly more than once recently. Loss of power/no acceleration. Once it had no acceleration when taking off from a stopped position, and then again it lost acceleration while driving at a speed of around 50mph the car would no longer accelerate, had to pull off to the side of the road and turned the car off and let it sit for a few minutes and then restarted the car and it resumed to function normally. There are no codes in the system, no warning lights, this has happened 4 different times now. Honda says they cant do anything if they cant make it repeat the problem when they diagnosis it and if the system doesnt have any active codes in it.

While driving on the NJ garden state parkway on an incline, the car went into limp home mode in the middle of heavy traffic causing the speed to get dangeriousily very slow. I had to make my way across many lanes to get the edge of the road. After shutting off car I was able to restart and drive to work. My father came to my work and looked at car and added Honda antifreeze becuase it had seeped into combustion chambers then drove the our Honda dealer. Just before he got to dealer driveway the car missed and hesitated but was able to make it to dealer. Dealer determined it was the common problem with the 1. 5t engines, the head gasket failed. Check engine light never went on or any overheating (I was lucky) . While engine was apart, other work was agreed to as being cost-effective. The car prevousily had Honda car with 0 deductable until 100,000 miles. Car has always been serviced by dealer with more service than Honda requires and I have all service records from purchase to prove it. Last service before incident was 10/14/2025 . What makes this worse is that my son (2018 civic) and my brother (2020 Accord) also have Honda cars that are destined for the same failure based on what is known about the defective 1. 5t engines.

The problem I am having with my vehicle Honda Accord 2018 is with the head gasket. I was on the highway and as I was driving suddenly all the signs came on the display and gave a warning that my vehicle is overheating and it came down to 20mph while I was on the highway. This was very risky to me and the other vehicle around me.
