2019 HONDA ACCORD Engine Problems

Check

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.

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

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...

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.

My vehicle started having issues with misfires approximately 2 years after I bought it in January 2020. I bought it new from the dealership in Salinas California. I took it to Morgan hill Honda for repairs. It’s had 2 misfires and I took it in for a Fuel pump recall. About 2 weeks later all my lights in my dash come on. I took it in to get looked at and they said it’s the turbo engine, $3k to fix it. I’ve had nothing but problems and it’s like a bandaid of a fix every time. The first time it happened I was merging onto highway [XXX] and it gave out and slowed down to 25MPH. I had to pull over to the shoulder almost caused an accident. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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.

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...

I am reporting a failed recall remedy. Honda was unable to provide parts for Recall 23V-858 for over a year. Operating the vehicle during this delay resulted in engine starvation, overheating, and a catastrophic cylinder head gasket failure. The dealer and manufacturer are now refusing to cover the consequential damage caused by their own delay.

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...

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...

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.

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.

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

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 !

While I was driving my car on the highway doing the speed limit of 60mph my car lost complete power and lost speed to below 20mph and would not gain speed. I pulled over on the highway turned the car off and back on. It begins driving again normal. The next morning it was mis firing so I took it in to the dealer and this is what I was told after getting a diagnostic check: FOUND CYLINDERS 1 AND 4 LEAKING COOLANT FROM THE HEAD GASKET. I RECOMMEND REPLACEMENT OF THE HEAD GASKET, FUEL INEJECTORS, AND SPARK PLUGS. HEAD MAY NEED RESURFACED. INCLUDED IS ALSO OIL CHANGE

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

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.

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

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...

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...

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...

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....

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...

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.

I bought this car used in August 2022. September 2022, I paid for diagnostics because every warning light was on. They returned the car and the warning lights were clear. They eventually reappeared. I called, complained and was told I would need to pay for another diagnostic. This has been an ongoing problem. The lights are: Collision Mitigation, braking system problem. TPMS system problem, check tire pressure. Brake System problem, brake performance may be reduced. Brake system, brake hold system problem, apply brake when stopped. Electric power steering system problem, steering assist reduced. Vehicle stability assist system problem, reduced traction and handling. Hill start assist problem, vehicle may roll upon brake release. ACC, adaptive cruise control system problem. Road departure mitigation system problem. Emission system problem, avoid heavy acceleration and high speed. When the battery is disconnected for 15 minutes, then reconnected the lights clear, only to reappear within a...

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...

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.

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...

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...

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.

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.

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...

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.

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

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

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.

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.

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.

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.

My vehicle dashboard was lit up like a Christmas tree with over $3.1K in repairs only for it to be the fuel pump!

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. 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,...

In December 2024, all of the lights on my dashboard came on & my car would not accelerate. The code indicated that it was a "Cylinder 2 Misfire." I replaced the ignition coil for cylinder 2 but my car continued to have the same issues. I had all 4 ignition coils replaced and all 4 spark plugs. In March 2025, all of the lights on the dashboard came on again with the car not accelerating properly. I had it looked at again, was told that it was a "Cylinder 2 Misfire" again but all 4 ignition coils were working properly. A spark plug was replaced at that time. Then, in May 2025, the car did the same thing with all of the lights coming and the car would not properly accelerate. The car again read that there was a misfire with "Cylinder 3" but all of the ignition coils worked...
