2019 Honda Accord Engine Problems

On April 14th, 2026 we were driving on the road, the car overheated. We shut it off, sat for a few minutes. Started driving again and had to sit in roadwork, within 1 minute the car started to overheat again. We pulled into the gas station, checked coolant levels, all fine. We let the car sit for 20 minutes or so, we tried to turn the car on and the engine started sputtering and all dash lights came on. We got the car towed to a shop, they looked over the car and told us that coolant had leaked into the cylinders and the head gasket was blown but there was no leak in any of the coolant areas. They quoted us over $7000. So we are out of a car while it’s at the shop waiting to get fixed.

Head gasket 2 has failed on my vehicle.

head gasket failure with less than 80,000 miles.

My 17 year old drives this car and has suddenly stalled and gone into limp mode 3 separate times (twice on busy highway) with no warning or codes provided. Most recently the vehicle alerted of overheating. After a couple trips to mechanic it was determined that head gasket is going out. It seems that this is a very common problem with this vehicle and an extreme safety hazard. Especially with young drivers as it sent my daughter into panic and nearly caused accident on initial breakdown.

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 NHTSA investigate and compel Honda to issue a formal recall for all affected 2018-2022 Honda Accord 1.5L vehicles. 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, 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.

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.

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.

Was told I have a blown head gasket on cylinder 3 with 90k miles on my vehicle. No check engine light has been on.

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.

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.

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.

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.

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.

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.

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

My vehicle’s fuel delivery system failed after a recall repair. The in-tank fuel pump was replaced under recall by the dealer, even though I had no drivability complaints, no warning lights, and a full inspection that day confirmed no issues with my vehicle. Immediately after the recall pump replacement, the vehicle developed drivability problems including sputtering, hesitation, and failure to start.On one occasion, the underside of the car overheated and exhaust fumes, including carbon monoxide, entered the cabin. The interior filled with heat and fumes, I became lightheaded, dizzy, and shaky, and nearly lost consciousness while driving. My dog, who was with me, vomited and panted heavily from the exposure. I had to pull over and exit the vehicle immediately. This incident occurred only after the recall pump was replaced and points to faulty installation or malfunction of the recall component, which disrupted the fuel system and caused improper combustion and exhaust handling. On another occasion, the vehicle stalled in the middle of an intersection, leaving me at serious risk of being hit by cross traffic. The car now shows a high-pressure fuel pump fault. Although the in-tank pump and the high-pressure pump are in different locations, they are part of the same system: the in-tank pump supplies steady fuel volume and pressure directly to the high-pressure pump. If the in-tank pump is defective, mis-installed, or inconsistent, it causes the high-pressure pump to fail. This made my vehicle unsafe to operate, placing me, my passengers, and other drivers at risk. The problem has been confirmed by the dealership, which documented a high-pressure fuel pump fault, and reviewed by Honda Corporate. Components and service records are available for inspection. There were no warning lamps, messages, or drivability issues prior to the recall service, all symptoms appeared immediately afterward.
