general problems of the 2019 Honda Accord - part 2

It’s started at 80,000 miles when my check engine light came on and it give a code p0302 so I change the spark plugs but when I replace it with the new one the code came but the code came off and after a few days later it came back on and it throw the same code. I believe that my head gasket is not good.

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.

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 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.

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.

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.

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 !.

In the past 2 months my car starting having rough idle issues. As recommended by the dealership, I replaced the head gasket as they said it was leaking coolant into the cylinder causing the rough idle. Almost immediately after paying for this, the dashboard lit up like a christmas tree with multiple warnings and the car went into limp mode, lost acceleration and would have been extremely dangerous had we been on the interstate or multi lane road. Took it back to the dealership, ran another diagnostic and determined the fuel injectors needed to be replaced. These repairs cost over $5,000. Recalls have already been put in place for models around this one and Honda should acknowledge these problems as it is wide spread.

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.

I have taken my car to the Honda dealership on multiple occasions because my car has stopped accelerating while driving on the interstate. The car will flash the check engine light and completely stop accelerating while driving. I was first told it was the fuel pump that was recalled and waiting over a year on the recalled part and multiple times breaking down while driving they finally replaced the part. After the dealership replaced fuel pump I continued to have problems unfortunately happening more often and worse than before replacing the fuel pump. I was then told my car was misfiring and needing a tune up which would involve replacing all four coil packs and spark plugs. I replaced all of these recommended parts with no resolution to my problem. I have since be told by the dealership my car needs all four fuel injectors replaced after running the diagnostic tests. After doing research it seems to be a common problem with this make and model car. I can’t believe with as many cars with this same issue and the safety issues with completely stalling in the middle of traffic there are no recalls on these cars.

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.

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.

While driving my 2019 Honda Accord, the engine began misfiring and losing power. A diagnostic scan showed misfire codes (p0300–p030x). The issue was traced to coolant leaking into the combustion cylinder due to a head gasket defect. This caused engine hesitation, reduced acceleration, and risk of stalling while in traffic. I have learned that Honda has issued a technical service bulletin (TSB) for this issue, but no recall. This is a serious safety concern because loss of power or stalling could cause an accident, especially at highway speeds or during turns/intersections. The repair is extremely costly for owners, and the defect appears to be widespread in 2018–2019 Accord models with the 1. 5l turbo engine. This should be investigated and addressed as a recall to protect drivers.

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).

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.

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.

While driving ~40 mph call all of a sudden lost power in middle of busy street, was not able to steer or drive (pedals weren't working to provide power). I pulled off to side and saw check engine light blinking and warning message pop up about brake system not working. I turned the car off then turned it back on and worked normally and was able to drive home.

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?.

All types of lights popped up such as emissions system problem tire pressure monitoring brake system problem vehicle stability electric power hill start acc collision mitigation road departure mitigation.

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.

My car has been sending several warnings including: brake system: electric parking brake system problem, brake system problem, brake hold system problem, adaptive cruise control system problem, collision mitigation braking system problem, road departure mitigation system problem, supplemental restraint system problem, and power steering reduction problem. My car is not even 100,000 miles yet. I have had all maintenance done on time and recently had brakes replaced. I have changed my battery and tires twice within the 6 years of owning the car. It seems this is a regular complaint for such low mileage. I was a Toyota person but switched to Honda for their safety performance, and now I am regretting that. I read that this is the turbo needing to be changed. This part should be recalled if it is failing soon. A person who just bought a car should not be paying $4500 in repairs already. I had the fuel pump recall replacement done, and had the brakes done. I am changing the spark plugs and ignition coils next week. Honda needs to do something about this and I am looking to join in the class action suit against them, if they do not correct the issue.

Component or system failed: the head gasket appears to have failed, leading to coolant leaking into cylinder 4. This has been confirmed by two separate service centers. The vehicle is currently available for inspection if needed. Safety risk: the failure caused engine misfires and dashboard warning lights to activate while driving, which could have led to a sudden loss of power or control. I had to pull over and restart the vehicle to regain drivability, which put my safety and that of others at risk. Reproduced or confirmed by a dealer or service center: yes. The issue was first diagnosed by Honda of sumner, who initially suspected a compression issue. Their master mechanic later confirmed it was likely a head gasket failure. A second opinion from greg’s japanese auto confirmed the diagnosis and provided photos showing coolant in the cylinder. Inspected by manufacturer or others: yes. The vehicle was inspected by Honda of sumner and greg’s japanese auto. No inspection has been done by police or insurance representatives. Warning lamps or symptoms before failure: yes. After a recent service (which included an ac repair, fuel pump recall, and oil change), I experienced two misfires in cylinder 4 within 24 hours. All dashboard warning lights came on during one of the incidents. These symptoms began four days after the service. Additional context: I was quoted $8,100 for the head gasket repair by Honda. I believe this issue could have been detected earlier during the diagnostic service. I’ve since learned of a class action lawsuit involving this exact issue in my vehicle’s generation, which makes me concerned this is a known defect.

The vehicle displayed engine warning message “emission system problem” at 70,000 miles and this appears to be present in many vehicles of this edition.

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.

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.

Lights go crazy in dashboard apparently due to constan cylinder misfires, spark plugs changed, same issue, fuel injectors and coils changed, same happened keep it getting fix and the problem persist, making the car dangerous to drive, since it loses power since the car it’s not able to respond and work as it should be having engine, steering and brake issues, problem has been confirmed by dealer. It hasn’t been inspected by manufacturer. The lost of power and acceleration it’s probably one of the symptoms before all the light go on again. It’s been several times that this happens and I know for a fact that many people are experiencing this issues due to turbo or head gasket failure. Might get that inspected soon.

It appears the head gasket failed due to an anomaly on the engine block between cylinders. We were driving down the road when the engine lost power and went into limp mode ( dealer term). The problem of the head gasket was confirmed by the dealer, but the anomaly on the short block has not been explained. The engine block was inspected by the service tech, service manager and a rep from Honda. No explanation given. No warning lights came on until immediately after the engine lost power. The engine block is available for inspection at the dealership.

My family's 2019 Honda Accord with ~80k miles suddenly had all the warnings lights flashing on the dashboard in early July 2025. The initial diagnostic reader showed a cylinder 3 misfire. After replacing spark plugs, the warning lights returned after one week; at that time, the ignition coil was replaced but the warning lights returned again after one week of driving. The Honda dealership performed further diagnostics and tests, ultimately reporting that the engine needed fuel injectors replaced and a head gasket. It is important to mention that when we initially called the dealership's service department to make an appointment, the service representative that answered the phone immediately recognized this issue, saying that it is a well known issue with Accord 1. 5 turbo engines. Honda corporate has stated that the car is outside of the manufacturer's warranty and that there is no recall. Note that there are class action lawsuits in the us on this matter, as well as lots of online traffic of car owners experiencing this issue with the Honda 1. 5t engine. It appears that there is a serious design flaw in the engine.

My vehicle dashboard was lit up like a christmas tree with over $3. 1k in repairs only for it to be the fuel pump!.

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.

Car randomly started misfiring took car to Honda was told the vehicle was low on coolant and needed the head gasket replaced.

Head gasket issues and car overheated.

Blown head gasket on 1. 5t engine. It is a common issue that so many owners of this engine have experienced. It was a safety risk because it happened going at 70mph on the highway, the head gasket blew and it limited the power of the engine. Suddenly, acceleration was no longer possible and the vehicle began limping. I had to drive for several miles at a speed of 35mph (the fastest my car could go no matter how much gas you give it) on the shoulder of the road to take the nearest exit and be somewhere safe. The problem has been confirmed by a certified Honda dealership. It the vehicle has been inspected by the Honda dealership. Symptoms that I have not confirmed to be related to the issue are missing coolant without any leaks. I had to refill the coolant without any visible leaks and there were not any leaks found by independent service center.
