I own a 2019 Honda Accord 1.5L with 112,985 miles. The vehicle developed a blown head gasket with coolant leaking into Cylinder 3. The failure was first confirmed via a combustion leak (CTR) test performed by an independent Honda specialist (Hond-Auto Specialist) on March 2, 2026, and later confirmed by an authorized Honda dealership (Vandergriff Honda, [XXX] ) via borescope inspection on March 23, 2026. Repair estimate is $4,799.81. This is a known defect. American Honda Motor Co. issued two internal Priority/Action Required memos to all Honda Service Managers and Advisors — April 2023 and August 2024 — confirming they were actively investigating this identical head gasket failure on 2018-2022 Honda Accords equipped with the 1.5L engine. Despite this internal investigation spanning multiple years, Honda has not issued a recall. A federal class action lawsuit [XXX] v. American Honda Motor Co., Inc.) has been filed alleging Honda knew of this defect before these vehicles were sold. I am requesting the federal safety agency investigate and compel Honda to issue a formal recall for all affected 2018-2022 Honda Accord 1.5L vehicles.

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The check engine warning light was intermittently illuminated. The contact restarted the vehicle to correct the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to the federal safety agency Campaign Number: 23V858000 (Fuel System, Gasoline); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 94,000.
The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, the messages "Engine Temperature Too Hot - Do Not Drive - Allow Engine to Cool" and "Engine Temperature Near Limit - Avoid Heavy Acceleration and High Speeds" were displayed. The contact pulled over and had the vehicle towed to the dealer, who determined that there was no coolant leak but that the head gasket was blown and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 146,000.
Car lost power on freeway, had the car towed to local Honda. After several hours of sitting at dealership and talking to several different employees. One employee comes back to tell me the head gasket was blown and needed repaired. And that this is a common issue he has been seeing in this make/model of car.
The turbo! Code P0299! Hundreds of thousands of Americans going through the same issue all their lights are flashing on their dashboard with these 1.5 T engines
Approximate date (around January 2026), location (e.g., Newburgh, NY area), and circumstances (e.g., during normal driving). No crash/injury mentioned in my case, but note if it stranded I, required towing, or felt unsafe (e.g., potential for sudden power loss). While driving, all dashboard warning lights came on suddenly. The vehicle experienced rough running/misfires. Dealer diagnosed low coolant, pressure tested the system, and confirmed coolant intrusion into cylinders 2 and 3 due to head gasket failure. This required full head gasket replacement (parts/labor ~$4,567 total before any goodwill). No external leaks noted initially. Concerned this could cause engine stall/overheat while driving, posing a safety risk.” Dashboard lights, possible misfire codes (if any DTCs like P0302/P0303 were pulled), low coolant without visible leaks. dealer diagnosis (Morehead Honda? from Eric Koller), repair done/recommended, cost, and that American Honda provided 35% goodwill (shows it’s out-of-warranty but recognized issue) Only 91000 miles on the vehicle.
Check
The contact owns a 2019 Honda Accord. The contact stated that while driving approximately 35 MPH, there was an alert that the engine was overheating displayed on the instrument cluster. The message to pull over and allow the engine to cool off was displayed. The vehicle was taken to a local dealer, who diagnosed the vehicle and determined that the head gasket had failed and needed to be replaced. The vehicle was repaired. The contact researched online and became aware that the head gasket failure was a known failure. The contact informed the manufacturer of the failure and was referred to the federal safety agency Hotline for assistance. The failure mileage was approximately 78,000.
The vehicle would overheat and lose power. At first, the dealer stated that they could not find the issue, which continued. I was not able to drive the vehicle, and I am a first responder, which caused issues getting to my job. Finally, one of the dealers advised that the head gasket had to be replaced. The dealer insisted that the head gasket was not covered under warranty despite my keeping the vehicle regularly serviced.
Was told I have a blown head gasket on cylinder 3 with 90k miles on my vehicle. No check engine light has been on.
I was taking my wife’s 2019 Honda Accord into a dealership for a factory recall with a fuel pump issue. After I dropped it off, I got a phone call, letting me know that they had some bad news and that the cars third cylinder had failed due to a blown head gasket and coolant leaking into the cylinder. There has never been a check, engine, light or code or sign of any kind of issue with this vehicle up to this point I have it regularly serviced at Honda dealerships after doing some research. This seems to be a recurring issue with people in this make and model of Honda Accord with the 1.5 T engine. I would like to have someone contact me regarding the expense related to this repair as I believe it should not be on the owner to cover such cost when it is a recurring and known issue with this vehicle.
Head gasket failure was noted and happened at about 95000 miles. Crack in a cylinder lead to leaking of coolant and caused misfires and check engine. Was let know that if ignored engine could “expire” at a random time if not dealt with asap could have lead to a crash, injury, or harm others or property. Has the problem been reproduced or confirmed by a dealer or independent service center? The problem was confirmed by dealer and partially before dealer by independent mechanic. Vehicle was inspected by dealer and trusted independent mechanic. Zero warning about failure up until failure. Vehicle entered safety crawl mode when engaged in any throttle with resistance up hill or on flat over 20 mph. First appeared just shy of 95000 miles. A known issue in many many of this specific make and model of car with varying years.
My vehicle started having issues with misfires approximately 2 years after I bought it in January 2020. I bought it new from the dealership in Salinas California. I took it to Morgan hill Honda for repairs. It’s had 2 misfires and I took it in for a Fuel pump recall. About 2 weeks later all my lights in my dash come on. I took it in to get looked at and they said it’s the turbo engine, $3k to fix it. I’ve had nothing but problems and it’s like a bandaid of a fix every time. The first time it happened I was merging onto highway [XXX] and it gave out and slowed down to 25MPH. I had to pull over to the shoulder almost caused an accident.

Engine began to have an odd stutter and trouble accelerating which was initially believed to be spark plugs after a full tune up did not fix the issue took to my local mechanic. Diagnosed the issue as bad fuel injectors likely due to the fuel pump recall. Code popped up as cylinder misfire initially which didn't make much sense considering a full tune up was completed less than a month prior. After further diagnosis issue was found to be a blown head gasket causing several thousand dollars in repair due to having to completely disassemble and reassemble the engine.
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.
I am reporting a failed recall remedy. Honda was unable to provide parts for Recall 23V‑858 for over a year. Operating the vehicle during this delay resulted in engine starvation, overheating, and a catastrophic cylinder head gasket failure. The dealer and manufacturer are now refusing to cover the consequential damage caused by their own delay.
Car started loosing power and fouling spark plugs 2 and 3. Took it to dealer shop and head gasket was bad.
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.
The vehicle, a 2019 Honda Accord, experienced a catastrophic engine failure (blown head gasket) and entered "Limp Mode" after being operated for approximately 18 months with an unaddressed, high-priority federal safety recall (the federal safety agency 23V‑858). The vehicle currently displays DTCs P0100, P0113, and P023D, which indicate severe air/fuel metering and boost pressure correlation failures. Primary Cause: Consequential Thermal Stress The primary cause is likely thermal degradation of the head gasket resulting from a prolonged "lean-burn" condition. Recall Defect: The recalled fuel pump impeller is known to deform, restricting fuel flow. Lean Condition: A restricted fuel supply causes the engine to run "lean" (too much air, not enough fuel). Lean combustion is significantly hotter than normal combustion. Heat Accumulation: Over 1.5 years of operation with this restricted flow, the engine experienced repeated, excessive thermal cycles that compromised the structural integrity of the head gasket. Limp Mode Trigger: The stored codes (P0100/P0113) show the ECU was struggling to compensate for the erratic fuel/air environment created by the failing pump. Secondary Assessment (The Dealer's Claim): The Service Advisor (Paul) has alleged that aftermarket components and a missing turbo gasket caused the failure. Assessment: While aftermarket parts increase scrutiny, a missing external turbo gasket typically causes an exhaust leak or loss of boost, not an internal head gasket failure. Contradiction: The dealer must provide empirical proof that these parts caused the failure, whereas the federal safety agency recall is a pre-documented, manufacturer-admitted defect known to cause the exact stalling and "limp mode" symptoms the vehicle is currently exhibiting. Conclusion: The most probable cause is manufacturer negligence. By failing to provide a remedy part for 18 months, the manufacturer forced the vehicle to operate under a documented defect that creates the exact high-heat conditions required to cau
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.
Defective fuel pump from fuel pump recall LED to faulty fuel pump injectors, which LED to all warning lights to come on at the same time. Honda is refusing to take responsibility of faulty parts that put the consumer at unnecessary risk of injury.
Blown head gasket, car never overheated. Suddenly lost power in highway and car died. Dealership is stating blown head gasket. Seems to be a common issue.
After the vehicle misfiring , kept changing spark plugs and coil , as well the vehicle shutting over while driving on the highway , having to get it towed and then finally able to get to dealership , Honda said the head gasket failed , so after the head gasket replacement and getting it fixed for $5K, it started to make a noise rattling , took it back to dealership and they said it was the Turbo when I took it back to dealership , they said it was failing , it was not making a noise until after head gasket replacement . The dealer said the turbo messing up wasnt from head gasket replacement , but I’m very aware it’s possible and there was absolutely no noise before replacement of head gasket !
Th head gasket failed in 2019 Honda Accord , it kept misfiring , causing vehicle to not run and shut down . After the dealership fixed the head gasket , it had now caused the turbo to mess up which the dealership said wasn’t covered . It was taken to Honda dealership
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 I was driving my car on the highway doing the speed limit of 60mph my car lost complete power and lost speed to below 20mph and would not gain speed. I pulled over on the highway turned the car off and back on. It begins driving again normal. The next morning it was mis firing so I took it in to the dealer and this is what I was told after getting a diagnostic check: FOUND CYLINDERS 1 AND 4 LEAKING COOLANT FROM THE HEAD GASKET. I RECOMMEND REPLACEMENT OF THE HEAD GASKET, FUEL INEJECTORS, AND SPARK PLUGS. HEAD MAY NEED RESURFACED. INCLUDED IS ALSO OIL CHANGE
While driving my 2019 Honda Accord, after about five minutes on the road, multiple warning lights suddenly appeared on the dashboard. The emission system, brake system, power steering, TPMS, ACC, hill start assist, collision mitigation, and vehicle stability assist warnings all came on at the same time. The alerts caused concern for safety, as several major systems such as steering assist, braking, and driver-assist features appeared to malfunction simultaneously. The issue seems related to an electrical or charging system failure (such as the alternator or battery), since all of these systems rely on stable voltage to operate correctly. The incident occurred without warning and could have resulted in loss of steering assist or engine power while driving
I bought this car and after only owning it for eight months, as I was driving down the freeway, every light on my dashboard lit up, and my car slowed down. I was able to pull to the side of the road, but I could no longer drive my car home and I was commuting. Since the first incident, I have repaired my car having the coil repaired spark plugs, and regular maintenance in the last eight months that I have owned the car and now my turbo charger needs to be replaced. I took it into two different mechanic shops. My car is only at 130K miles this should not be causing an issue with a Honda now I cannot find anyone to repair it without costing me $2000 plus.
I have a 2019 Honda Accord sport 1.5T that has a blown head gasket. I took it to the dealer and opened a case with Honda through their good will program, but was recently denied because they claim there was no manufacturer defect after the dealership inspected it. There seems to be a lot of people that are having the same issues with this engine, and there are a couple lawsuits against Honda regarding it. The car was inspected at a Honda dealership and they diagnosed it as a blown head gasket and quoted the repair of $5200. A case was opened with Honda corporate through their Goodwill program, but was recently denied as not a fault of the manufacturer. The car overheated on 10/10/25 while driving, potentially leading to engine damage
