general problems of the 2019 Honda Accord - part 1

I have a 2019 Honda Accord sport 1. 5. I was driving on the freeway last week and my car did not allow me to accelerate anymore. Car went to an unsafe highway speed and it was hard to get to a shoulder where can safely stop. I felt my safety was compromised by this issue. All the warnings appeared on my dash and all the lights went on. No warnings prior to this problem. I am needing a new head gasket and repairs are estimated over 5k. I know there is a class action lawsuit against Honda because this issue is extremely common. I need help. I can’t afford these repairs and I depend on my car for transportation to work and child care daily. Please hole Honda accountable for this is very dangerous and very common.

My Honda Accord keeps trying to turn off in the middle of the fwy and I know it’s due to the fuel pump, I have a misfire and all the warning lights came on. This is due to Honda having the fuel pump recalled that has damaged all the fuel injectors. It took them almost a year to get the recall parts and now myself and a ton of others are now having to pay for these fuel injectors to have a car that doesn't stall and die on the road. Honda should have taken care of this knowing it damaged the fuel injectors. Also issue with air bad supplemental issues.

While driving my 2019 Honda Accord hybrid at highway speed, the engine suddenly suffered catastrophic failure. The engine block ruptured, leaving a large visible hole with internal engine components exposed. Oil was expelled into the engine bay and ignited/burned briefly. This occurred without prior warning at highway speed and created a sudden loss-of-propulsion hazard. The vehicle has approximately 48,500 miles and has had regular on-time maintenance via Honda dealership. No warnings or other symptoms were active prior to engine rupture event. Fire dept & nys police arrived on scene prior to being towed. The vehicle is currently preserved at sussex Honda dealer for inspection and awaiting diagnosis.

Blown head gasket. Engine lost power and forced me to pull over. The problem is well documented with this generation of Honda 1. 5t engines, Honda dealership confirmed problem and second opinion from independent shop also confirmed, citing they had another Honda with the same 1. 5t engine with the same blown head gasket issue. No clear warnings prior to event, all the dashboard lights flashed on when car lost power.

While driving, my check engine light cam on suddenly, along with my entire dashboard lighting up with all kinds of warning lights. At that moment, the engine ran very rough while attempting to push the accelerator pedal to maneuver out of traffic, feeling like there was no power. With that, I also noticed the temperature gauge start to increase towards the hot limit, though there was no venting of steam from the radiator. I stopped my car on the side, turned the car off, and waited u til it cooled down before attempting to start it again. When restart after a period of time, I noticed what smelled like coolant coming from the exhaust. I have not been able to bring the vehicle to a mechanic to diagnose the issue just yet.

My car has under 100k miles and has regularly been serviced throughout its life. The head gasket failed due a known design flaw.

10th gen Honda Accord has a major engine design flaw allowing coolant to pass through the gasket mixing with fuel in the cylinders causing premature head gasket repair which also puts the injectors under immense stress due to high compression. While driving my 2019 Honda Accord to the dealership for inspection. All the lights started flashing on the dash. Highlighting - critical failure detected please stop driving when safe. After a few mins the car’s infotainment system shut off no electrical activity and the car shut off mid drive. Luckily, it was in the morning and not during peak traffic congestion. Had I been going on the expressway I could’ve harmed myself, or someone else. This is highly unacceptable that a car with only 96k miles has a serious engine issue like this. I have maintained the oil changes at the required intervals, changed the fuel pump under recall, tires, brakes etc. After towing to the dealership. Diagnostics were performed and it was confirmed that the coolant was empty and radiator low. Which then prompted the dealer to perform a borescope test for the cylinders and it was found that cylinder 3 had a misfire and was leaking coolant into the cylinders causing premature wear on the gasket as well. The car is out of warranty and the service advisor said to me that they had another Honda just like mine with the same issue. This isn’t an isolated incident and many owners with the 10th gens have the same exact issue nationwide and Honda turns a blind eye and expects us to pay over 6,000 for the repair it’s a total scam! they are making money hand over fist without any recall and just scamming their customers. This is truly unacceptable and should be investigated immediately and Honda reprimanded!.

Blown head gasket, white smoke from the exhaust. Loss of power. All warning lights on the dash started blinking. Dealer gave estimate of $6500.

On 5-11-26, I was driving and the vehicle just stopped in the middle of the roadway. I couldn’t go in drive or reverse, just sitting with engine running. No warning lights, no noise, or anything that would let me know there was a problem. Cars was coming up behind me and in front. I called a towi truck, and a police officer. The officer pushed me off the road way, and the car was towed.

Vehicle: 2019 Honda Accord sport 1. 5l VIN: [xxx] mileage: approximately 122,497 my vehicle experienced a cylinder head gasket failure accompanied by coolant intrusion into the engine cylinders, injector-related issues, fuel trim failures, and cylinder misfires as diagnosed by an authorized Honda dealership. Prior to diagnosis, the vehicle experienced engine performance concerns associated with the misfire condition. The dealership documented historical misfire events and coolant intrusion into the combustion chambers. I am submitting this complaint because I am concerned that injector-related issues, engine misfires, coolant intrusion, and cylinder head gasket failures may represent a recurring condition affecting similarly equipped vehicles. Engine misfires and coolant intrusion can potentially result in reduced engine performance, loss of power, unexpected vehicle behavior, or engine failure while the vehicle is being operated. I request that NHTSA review this issue and determine whether a broader investigation is warranted. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Vehicle was being driven on the highway when suddenly engine hesitated and started stalling. Speed was reduced from around 65mph down to the low 40s. Cars were stacking up behind and passing, causing potential hazardous conditions. Vehicle was taken to a mechanic shop and diagnosed with misfiring, after reading obd ii with many alerts coming on. Further diagnostics revealed cylinder head gasket was leaking coolant into engine, as shown by borescope images. This is a known problem on 2018-2020 Honda Accords with both 1. 5t & 2. 0 engines. The multiple alert messages started to come on a few weeks ago, but the engine hesitation and stalling just started this week. At first we suspected a 12v battery issue, but testing confirmed battery was at 12. 8v with no issues.

Upon recent repairs completed by an official Honda licensed dealership for the fuel pump due to the related issue of stalling, misfiring, insufficient fuel economy and safety concern. My vehicle has continued to stall, misfire or idle extremely rough. Upon local investigation the error code p0203 and p0303 have populated as the most recent issue. No longer allowing me to drive the vehicle as it remains in limp mode. Previously error codes such as p0304 and p0302 as well as the associated error codes for the injector circuits indicating “open” have previously been detected intermittently and now permanently. In previous events within the last 3 months I have been stranded on highways due to the same stalling, misfiring and limp mode issue after I have previously been inspected by a Honda dealership and promised the issues would resolve. Unfortunately driving at respectable highway speeds and even local city limits my safety as well as my child and spouse’ safety have been put at risk due to the sudden deceleration caused by consistent misfires or limp mode effect which can cause me to have a collision with no warning. I have nearly been in 3 accidents due to this persistent issue.

The car is consuming coolant but not leakage anywhere and has misfires at start, it has a blown head gasket.

The contact owns a 2019 Honda Accord. The contact stated that while driving 80 mph, the vehicle unexpectedly lost motive power and stalled with several unknown warning lights illuminated. Additionally, the check engine warning light was illuminated. The vehicle was able to restart; however, there was a cranking sound coming from the vehicle. The contact stated that the failure had reoccurred several times while driving. A mobile mechanic inspected the vehicle and cleared the warning lights. The mobile mechanic retrieved dtc: p0078 (fuel rail pressure failure). The vehicle was not repaired. The vehicle was later taken to the dealer, but it was not diagnosed or repaired. The contact was informed that the failure could not be duplicated and that no fault codes were found. The manufacturer was made aware of the failure. The approximate failure mileage was 97,000.

The vehicle began experiencing engine performance problems including rough idling, vibration at startup, and a check engine light. Diagnostic testing indicated a misfire condition. Further inspection suggested coolant intrusion into the engine, consistent head gasket failure. The issue appears to involve the engine cooling and combustion sealing system (head gasket), which is a critical internal engine component. When the problem occurs, the engine runs poorly and may lose power, increasing the risk of stalling or failure while driving, which could create a safety risk in traffic. The problem was confirmed through diagnostic testing at a service center. Compression testing and engine diagnostics were performed, and results pointed toward internal engine issues. No repair has yet resolved the underlying problem. Warning indicators included the check engine light, engine vibration, and rough running conditions, which appeared prior to diagnosis. The issue has been observed consistently since symptoms first began and has not been fully resolved.

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.

I have a misfire and all the warning lights came on. This is due to Honda having the fuel pump recalled that has damaged all the fuel injectors. It took them almost a year to get the recall parts and now myself and a ton of others are now having to pay for these fuel injectors to have a car that doesn't stall and die on the road. Honda should have taken care of this knowing it damaged the fuel injectors.

The contact owns a 2019 Honda Accord. The contact stated that while driving at varous speeds the vehicle the had experience acceleration hesitation and the check engine light had illuminated. Later, while driving the engine went into limp mode and over the vehicle speed did not accelerate above 15 mph. The vehicle was later towed to the local dealer who diagnosed that the fuel injectors were faulty and needed to be replaced. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline. The contact was informed that the VIN was not included in the NHTSA campaign number: ( ). The contact indicated that the vehicle had experienced that same failure listed in the recall. The failure mileage was 135,019.

The contact owns a 2019 Honda Accord. The contact stated that while at the stop sign to access the feeder road, while accelerating, the lights started flashing on the instrument cluster. The vehicle failed to accelerate above 5 mph. The driver turned on the hazard lights, made a u-turn, and pulled over a block away at a stadium. The vehicle was turned off. The contact retrieved dtc: p0301, p0302, p0304, and p0300. A code reader was used to erase the codes. The vehicle was restarted and driven as designed. While the contact’s wife was driving, the vehicle failed to exceed 5 mph. The vehicle was taken to the dealer for a routine recall repair on the fuel pump and software. The dealer informed the contact that the failure was not related to a recall. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA hotline. The failure mileage was approximately 85,000.

Head gasket failure was diagnosed by a certified dealer. The only symptom leading up to the failure was slight hesitation when starting the vehicle. Safety issues include sudden engine power loss, engine fire, overheating, and reduced visibility from thick white smoke, and the potential loss of steering or braking power.

Head gasket 2 has failed on my vehicle.

My car started getting hot, began to overheat. I was on my way home on freeway. Second lane from slow lane. My car began to loose power, I could no longer excelerate. There was a big rig coming up behind me he was not slowing down as he got closer began honking I was trying to flag him that I could not move, as I was trying it started to go like 5 miles per hour where I began slowly to get over, cars in the other lane slowed down. Big rig went around me and avoided any collision. Thank god. I slowly made my way home on the streets with heater blasting. I towed my car to the dealer. I was told, my head gasket needed to be replaced, more than likely I would need a knew engine. Dealership said it was because when taken my car in for service I did not bring to the dealership. Cashier told me that there have been several incidents as mine. To my surprise I googled 2019 Honda Accord engine, and there were many with the same issue same car same year. Yet no recalls! I was lucky not to have been killed or have caused a multiple car collision. Are we waiting for someone to be killed to recall these engines. I missed several days of work, borrowed cars and rented a car to get back and forth to work not to mention the tramatic experience of a big rig coming at you honking on a freeway. A week prior to this incident, my lights on the dashboard came on. I did call the dealership to set up an appointment. At that point they were no signs of overheating. I have taken my care in faithfully for oil changes where all fluids are checked, I was not told not once that any fluids were ever low, last visit was approx 5 months ago. I have called to have them send me all receipts. However in hindsight I do not need theses records as it has been proven by other people they have had the same experience. We are not talking about a faulty air conditioner we are speaking of an engine, in my case power failure. In the even records of oil changes and dealership diagnosis is required. I can email.

The contact owns a 2019 Honda Accord. The contact stated that while operating the vehicle, several unknown warning lights illuminated. Additionally, the tire pressure monitoring system, emissions system, abs, and electric power steering warning lights were illuminated. Additionally, there were alerts for the adaptive cruise control, collision mitigation, and road departure systems displayed. The vehicle was taken to a mechanic, where it was diagnosed with fuel injection failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 137,708.

The contact owns a 2019 Honda Accord. The contact stated that while driving at various speeds, the vehicle would independently activate into limp mode. The check engine warning light illuminated. The vehicle was taken to a local dealer, where it was diagnosed with a turbo, head gasket, and fuel injector failure. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 112,000.

Head gasket failure with less than 80,000 miles.

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 NHTSA 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 vehicle's head gasket failed prematurely, resulting in coolant intrusion into the engine cylinders and combustion chamber. This caused the engine to unexpectedly overheat while driving at highway speeds, creating a severe safety hazard and loss of acceleration in active traffic. Additionally, it had a very rough idle when starting.

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.

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.

When driving home one night the dash board in the car all of a sudden hade a lot of warning lights come on. I brought it to my mechanic to have a look at it and he suggested to change the spark plugs and the coils which was done and he cleared the codes. About two days later I went to go to work and once again all the warning lights on the the dash board come on and it wouldn't drive over 5 mph. The mechanic went deeper into the problem he said it was cylinder # 3 that had a misfire and the fuel injectors needed to be changed which was done($1,000 later). A week went buy no lights on the dash came on but it has a rough start and when you get to about 40 mph the car starts to hastate to move. This time I brought it rick case Honda to have it looked at and they are telling me it is now the head gasket on cylinder # 3 has a hair line crack and needs to be changed ($7,400) to remove and replace the head gasket. This happened over multiple weeks between bowering cars waiting for parts. Now I have find a way to pay a $7,400 bill.

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.

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).

Description of incident: 1. Component/system failure: the engine cooling system and head gasket failed. A certified shop has confirmed coolant intrusion and a failed leak-down test on cylinder 2. The vehicle is available for inspection upon request. 2. Safety risk: my safety and the safety of my family and other drivers were put at extreme risk. On March 1, 2026, the vehicle suffered a sudden loss of motive power while traveling at 70 mph on the freeway. The car dropped to 15 mph instantly, forcing me to maneuver across active lanes to a narrow shoulder with almost no space. I was nearly hit by high-speed traffic. This has occurred over 8 times since 2023. 3. Confirmation by service center: the problem has been reproduced and confirmed by an independent service center on site lube auto & tire. They utilized a borescope and leak-down test to verify the internal engine failure. 4. Inspections: the vehicle has been inspected by a certified independent technician. I am in the process of notifying the manufacturer (Honda) of these findings for their inspection and accountability. 5. Warning lamps & symptoms: prior to the total power loss, the vehicle displayed engine temperature warnings and "check engine" lights. These symptoms first appeared approximately 8 months after purchase in 2023 and have progressively worsened, leading to the current engine failure. 6. Additional notes: this failure is identical to issues cited in active class-action lawsuits regarding Honda's engine defects, affecting both standard and hybrid models. I am communicating via written report/email for documentation and accessibility purposes.

City street driving speed < 35-40 mph, engine began rough idling at stop light after traveling just 1/8 mile. After driving less than 1 mile on level ground, engine slowed and would not accelerate above 20 mph. After another mile or so, increasing uphill grade caused speed to slow to 12-14 mph. Stepping on gas caused car to slow down even more, with shaking and jerky stop-start of vehicle. Maintaining 10-12 mph permitted vehicle to continue uphill climb for a few more miles so I could reach home. Downhill coasting was smooth with no gas pedal acceleration. Overnight parked in garage, and no problems driving vehicle to local independent auto mechanic. They were able to duplicate problem after 2 days and multiple test drives. Diagnosed permanent and temporary engine codes: misfires of cylinders 1 and 4 with ignition coil malfunction, misfires of cylinders 1, 2, 4, and random misfires. Also permanent codes: antilock brake ecm failure, electric power steering vehicle stability assist system malfunction, electric servo brake electric power train system malfunction. Mechanic removed coils and spark plugs, found cylinder 4 has moisture. Coils, plugs cleaned and re-installed. Honda dealer unable to duplicate problem after 3 days.

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.
