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 (NHTSA 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 NHTSA 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.

- Dayton, OH, USA

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 !

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

Why the 2019 Honda Accord Turbocharger Deserves a Class Action Lawsuit Many 2019 Honda Accord owners equipped with the 1.5L or 2.0L turbocharged engines have experienced serious and recurring issues with their turbochargers and related engine systems. These problems often appear prematurely and result in expensive repairs, performance loss, and potential safety risks -?" all of which suggest a manufacturing or design defect that Honda has failed to properly address. 1. Widespread Turbocharger Failures A large number of owners have reported: -??Turbocharger failure or malfunction well before 100,000 miles. -??Loss of engine power, whistling noises, or -??limp mode-?? warnings. -??Excessive oil consumption and contamination caused by turbo seal leaks. These are not isolated incidents -?" they indicate a pattern of premature component failure. 2. Manufacturer Awareness Without Proper Remedy Honda has issued technical service bulletins (TSBs) acknowledging certain turbo-related problems, but no recall or extended warranty has been offered to cover affected owners. This shows awareness of the issue but a lack of full accountability. 3. Potential Safety Risk When the turbo fails, the vehicle can suddenly lose power -?" especially dangerous during highway driving or merging. This transforms a mechanical issue into a potential safety hazard. 4. Financial Burden on Owners Turbocharger repairs can cost $2,000-?"$4,000+, often out of pocket since Honda claims these are not -??defects.-?? Many drivers are left paying for repairs on vehicles that should not experience such failures this early. 5. Possible Breach of Warranty and Consumer Protection Laws

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.
