2019 Honda Accord Engine

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.

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.

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.

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 NHTSA Hotline for assistance. The failure mileage was approximately 78,000.

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.

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.

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.

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

2019 Honda Accord 1.5L turbo has confirmed cracked head gasket at 94,000 miles verified by certified mechanic. No prior warning light indicator. Car began misfiring and jerking while driving and was unable to accelerate. Took several weeks before the dash displayed any warning light indicator. After doing research, we were made aware there is a class action lawsuit against Honda Motor Company for this being a known issue in 2018-2022 Accords and it was never disclosed or addressed properly by Honda. This is a major safety concern as the car can shut off while driving, jerk, shake and lack acceleration.

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.

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.

I have been driving my car and it won’t accelerate and it’ll be in traffic and I’m afraid I’m going to get into a wreck or break down in the middle of the road. I can hear fluid releasing and when we looked into it, I was losing coolant and looks like it may have vans going into oil. I can’t afford to get this fixed. Now my husband is affected by the government shutdown and it also seems like no one will fix it. I can go to dealership but I’m paying so much every time and it’s so hard. I need this vehicle for work and I can’t drive it. There’s been a couple incidents. I can’t pin point the exact date. I take it to the shop and I’m being told it was something else. I get that fixed and I have been up to date on maintenance of the vehicle. What can I do to get some kind of assistance?

Vehicle Information: Make/Model/Year: 2019 Honda Accord VIN: [XXX] Mileage at time of issue: ~70,000 miles Engine: 1.5L Turbo (if different, update before submitting) Dealership: Capitol Honda San Jose, California Complaint Summary: Engine misfire, rough running, and head gasket failure allowing coolant into cylinders. Details of the Problem: At around 70,000 miles, my 2019 Honda Accord began running rough and misfiring. Our independent mechanic scanned the vehicle and found failure codes for cylinders 2 and 3. The spark plugs and ignition coils were replaced, but the car continued to run poorly and the misfires persisted. We then took the vehicle to Capitol Honda in San Jose, CA. The dealership performed a diagnostic inspection and a borescope test, confirming coolant intrusion in the combustion chambers. They diagnosed the vehicle with a blown head gasket, noting visible coolant in cylinders 2 and 3. This car has been carefully maintained, never overheated, and serviced on schedule. Head gasket failure at this relatively low mileage is abnormal and appears consistent with defects reported by other Honda owners involving turbocharged 1.5L engines. This condition can cause rough idling, loss of power, and potential engine stalling, creating a safety risk while driving. Repair costs are significant and may indicate a systemic defect in this engine design. Requested Action: Please investigate head gasket and coolant intrusion failures in 2018–2022 Honda Accord models, especially those with the 1.5L turbo engine, as this issue appears to be increasingly common and poses a risk of sudden engine failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, several unknown warning lights were illuminated. Additionally, the contact stated that the failure had occurred several times. The vehicle was taken to the dealer where it was diagnosed with coolant intrusion and engine failure. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The vehicle was taken to an independent mechanic for a second opinion and price comparison. The manufacturer was not made aware of the failure. The failure mileage was approximately 104,000.

At 98,000 miles, the head gasket is blown. From a safety concern, the car goes into LIMP mode while driving and had to swerve out of traffic. A Honda Certified Dealer Service center confirmed the Blown head gasket It was only inspected by Honda Mechanics. The threw a service engine soon warning lamp which disabled the engine. This happened a few times while driving before getting it diagnosed.

In May of 2025, all the lights on my dash lit up and I began getting notifications about my systems not being available. I took my car to my local Honda dealership and was told that there was an issue with the clips on my turbocharger and they would have to be replaced. I laid $309 + $120 diagnostic to have that tested and fixed. I drove the car for exact two weeks, and the same issue occurred, I returned my car to Honda and they told me my engine air filter needed to be replaced, so I paid for that. The very next day, the same thing happened. I took my car to Honda on 06/09/2025, and they had it for roughly 90 days. In September, I was told that I had a cracked head gasket and my turbocharger was bad. I was quoted $7640.35 to fix this issue. I then began to do research and noticed there was a Facebook group called 2018-2022 Honda Accord - blown head gasket, where many people were having the same issue with their car. Ultimately, it cost $7100 to get my vehicle fixed. I don’t believe it’s a coincidence that so many people, living completely different lives, are having the same issue with their 2018-2022 Honda vehicle. This needs to be investigated.

Took my accord into service due to engine light warning, vibration on start up and to get the recall fixed. Was informed that my head gasket was misfiring and needed to be replaced, and was quoted $4515.37. The vehicle had been well maintained and low mileage at 72,000. This seems to be an issue with the 1.5 Turbo from 2018 to 2022 based on the online research. I decided to trade my vehicle in for a new one, but received $3500 less on trade in due to the bad head gasket. I'm also concerned about the safety hazard this could potentially have been. My daughter has a 2020 accord.

Head gasket issues and car overheated

NHTSA Vehicle Safety Complaint Vehicle: 2019 Honda Accord 1.5T Engine: 1.5-liter Turbocharged (L15B7) Mileage at Failure: 88,000 miles Issue: Blown Head Gasket / Coolant Leak / Engine Stalling Summary of the Problem: At approximately 88,000 miles, my 2019 Honda Accord 1.5T began exhibiting signs of a coolant leak and engine performance issues. After diagnosis by a certified mechanic, it was confirmed that the head gasket had failed, causing coolant to leak into the engine. This led to overheating and a dangerous engine stall while I was in active traffic, posing a serious safety risk.

A blown head gasket can cause sudden overheating, misfires, and loss of power, all of which jeopardize the safe operation of the vehicle. This occurred without any warning lights or prior symptoms, making it even more dangerous. Repair Cost: The repair for the blown head gasket and associated engine work cost me $3,800 out of pocket, despite the vehicle being well maintained and relatively low mileage for this type of failure. Maintenance & Vehicle History: The car was serviced regularly according to Honda’s recommended schedule. There were no prior signs of overheating or misuse. The stall happened suddenly, requiring the vehicle to be pushed to safety to avoid blocking traffic. Wider Problem Indication: This issue appears to be widespread among 2019–2021 Honda Accords with the 1.5T engine. Many owners report similar head gasket failures, indicating a potential defect in the engine’s design, materials, or thermal management. Requested Action: I respectfully request that the NHTSA investigate this issue as a safety-related defect, and that Honda be required to issue a recall, extended warranty, or reimbursement program to address these premature and dangerous failures.

Head gasket blown out at 55k miles

Out of thousands of 2019 owners, my head gasket has blown. This isn’t right.

My 2019 Honda Accord with the 1.5L turbocharged engine is experiencing serious engine issues, including coolant leaking into the engine cylinder, oil contamination, engine misfiring, and overheating. This is a known issue and the subject of a federal class action lawsuit (Bissell v. Honda, Case No. 3:24-cv-02286). Honda has not issued a recall or repair program for this defect, and I am now out of warranty and facing costly repairs. This is a safety concern and I urge the NHTSA to investigate.
