general problems of the 2019 Honda Accord - part 2

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.

My vehicle had been running fine up until the dash lit up, engine check turned on along with the tire pressure sensor and as of right now my car does not accelerate.

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. Safety concern: the vehicle stalled unexpectedly in traffic due to the head gasket failure, putting me and surrounding drivers at risk of a crash. 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.

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.

On may 13, 2025, I took my car to the Honda dealership, because all of the lights on the dashboard came on. I was told that the clips on my turbocharger needed to be replaced, and so Honda fixed that $120 (diagnostic fee) $209. 99 to fix the issue. I was traveling so they kept the car for a week. I received the car back, and about 2 weeks later, 06/03, the same thing occurred, I was told that the engine air filter needed to be changed, and it caused the lights to go off $32. 84. The next day 06/06, the lights went off again. I took my car back to the Honda dealership and they had the car from 06/09 - 09/04. Today they have reached out to say “it took a while to recreate the issue because they are ‘masking each other. ’ there is a leak in the head gasket, and the turbocharger is going out. ” it would be cheaper to buy a used engine and used turbocharger than to have it rebuilt. ” I have spoken with other Honda owners, who have a 2018-2022 Honda Accord, that have experience the same issue.

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.

Emission system control error please see your dealer do not accelerate at high speeds, acc control, module error, brake system failure, error, lane control, assistance, failure, numerous lights illuminate on dashboard 7 to 10 error codes all at once. Vehicle was taken to diagnosed and found turbo charger for engine acceleration was faulty, spark plugs changed, 4 coils and cam shift sensors2 total. Over $3000 later, the vehicle is still doing the same mention above, including when stopped and acceleration at slow or high speeds vehicle jerks. Only 158,000 miles on a 2019 all fluids have been serviced and changed on time with no leaks.

1. Component: the engine head gasket and the combustion system (specifically cylinder 2). Specifics: a leak-down test confirmed a failure in cylinder 2, leading to coolant intrusion. This was initially masked by a water pump code, but after the water pump was replaced and the code returned, a borescope confirmed "clean" pistons (steam-cleaned by coolant) and tap scarring. Availability: yes, the vehicle and all diagnostic records are available for inspection. 2. Emergency maneuvers: on multiple occasions, the car entered "limp mode" while driving 70–75 mph on the freeway. This caused a sudden, dangerous drop in speed, forcing me to maneuver through high-speed traffic to reach the median/suicide lane. Stranded: the vehicle overheated 5 times in one trip, leaving me vulnerable on the side of a busy freeway. 3. Yes. An independent shop confirmed the failure via a leak-down test, a borescope inspection, and physical analysis of the spark plugs. They confirmed that despite the computer throwing a water pump code, the mechanical failure is the head gasket. 4. Status: it has been inspected by an independent service center. I am now using their findings to pursue a lawsuit/claim against Honda for selling a vehicle with a pre-existing internal engine defect. 5. Timeline: symptoms began in April 2024 (two months after purchase). Initial signs: an "emission system" warning light appeared. The diagnostic code indicated a water pump failure, which was replaced in April. Recurring symptoms: in November, the car suffered multiple misfires and "limp mode. " in March, the "emission system" light and the same water pump code returned, but the shop confirmed the pump was functional and the true cause was the head gasket leak into the cylinders.

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

Was driving on freeway my car wouldn’t go faster than 45 mph. Check engine light all of a sudden came on. Cars almost hit me from behind because my car wouldn’t accelerate. Had to pull over at the exit. After pulling over and shutting down the car, I turned car back on and all warning lights came on. I was able to drive slowly to a Honda dealership which was about a mile away. Had to pay for a diagnosis and they discovered that the coolant expansion tank was completely. Bubbling emerged from radiator after doing a coolant test. Up. The head gasket is leaking and need to be replaced. Cylinder head needs resurfaced.

I was driving on the freeway and my engine lost power and all the lights on my dashboard went haywire. I tried to get off the freeway but with the loss of power made it extremely difficult and dangerous. I thought I was going to get into an accident since my car slowed down so abruptly. I had to limp my way across traffic which was very scary. The car was jerking and shaking. I finally got to the side of the freeway and the car did not want to continue so I called for a tow truck and waited on the side of a busy highway. The tow truck brought my car to the Honda dealership which diagnosed the problem immediately as a blown head gasket. They said it was a known problem and the mechanic knew what to look for. They fixed the head gasket and I have my car back. My car only has 92k miles and I don’t think the head gasket should fail this early in the vehicles life. I properly maintain my engine with routine oil changes. There is no reason the engine should break down like this. I feel that there is a defect in Honda’s head gasket.

I am writing to express my serious dissatisfaction with the engine head gasket on my 2019 Honda Accord exl. Following my Honda consultant, I have experienced a engine head gasket malfunction where it has a head gasket crack. This led to leaking into the engine piston which will cost me $5000 to repair. There was no signs and symptoms that the incident was going to happen. I would also say I am a pretty conservative driver when commuting. The ongoing engine issues could potentially lead to serious safety concerns due to overheating, possible engine damage, and safety for others on the road. This problem has not been confirmed by the dealer and on many public forums people have had similar issues with this when there car is fairly new.

While driving my 2019 Honda Accord at approximately 65 mph on the highway, the car suddenly lost power, went into limp mode, and the steering wheel locked up. I was unable to turn or control the vehicle, which resulted in another car crashing into me. I sustained injuries in the accident and required medical attention. The incident was extremely dangerous and could have been fatal. After being towed to russell & smith Honda, they confirmed a blown head gasket was the cause of the failure. This issue is already the subject of a class-action lawsuit due to known design flaws in the 1. 5t engine. Honda only offered partial assistance, leaving me responsible for thousands in repair costs. This vehicle is unsafe and needs to be investigated immediately.

1. Headgasket, fuel injectors, and fuel pump failed on this vehicle. Upon inspection gwinnett place Honda responded that this was a very common problem and that they see upwards of hundreds of cars per month equipped with the 1. 5 liter turbo charged engine. 2. This affected my safety because during the whole ordeal my car went into a “limp mode” while doing 80mph down a busy highway causing me to rapidly lose speed and most cause a major accident. Unable to get off the road way due to my car shutting off I needed to have bystanders block a lane and push the vehicle off. 3. Yes it has been reproduced by both a Honda dealership and an independent service center 4. Honda stated that they wanted to swap the motor so they could send it to the manufacturer to have it studied, however in return I would be getting a motor with 90,000 miles while having to pay $12,000. 00 out of pocket. 5. The car was showing a “christmas tree” dash with every light on ranging from check engine, power steering, abs, lane mitigation, and climate control. On early mornings the car would have a misfire on startup due to the fuel injectors and during the day it would lose coolant however not leak it out.

I feel like my car should be under recall it’s so many other who experiencing the same thing. All of my lights are on, on the dash. Check engine light down to my cruise control not working. As I drive it’s stalling and jerking. I went to the dealership to have my spark plugs and my fuel injectors replace and it started back doing the same thing. Spent thousands just to be going through the same exact thing.

Car failed to start and all warning lights on dash were present. To restart the vehicle, the battery was disconnected and reconnected. As a result, the 2019 Honda Accord was taken to the dealership for repair. Upon inspection by the dealership the fuel injectors needed to be replaced. The recall part is still unavailable.

On January 22, 2025, I was driving at highway speed and suddenly my car seemed to lag in power. It slowed from about 60mph to 40mph and pressing on the gas did not do anything. The check engine light began flashing. I felt like it would continue to slow down and it was rush hour. I managed to safely exit the freeway and parked the car. I turned it off, waited a moment, turned it back on. It seemed ok so I drove carefully using back streets to the local Honda dealership. They kept the car for 2 days and ran tests but nothing showed on their computer and they could not replicate the problem. They gave me the car back. I saw another recall today for other models of Honda that have this exact problem. My car has 41700 miles on it. The weather was cold but clear. This is the first time this has happened.
