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
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 maintenance of the vehicle. What can I do to get some kind of assistance?
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)
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.
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.
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 few miles of driving. This is very concerning. My teenager will be driving soon and this is an unacceptable safety issue.
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.
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 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.
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.
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.
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 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.
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
the federal safety agency 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 federal safety agency 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.
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 properly. I had the fuel injectors replaced and another spark plug replaced. The car didn't even make it 24 hours before all the lights came on again. The RPMs in the car now go past "3" but will not accelerate & shift gears. The Honda Dealership has advised me that the head gasket needs replaced. My car has 74,000 miles on it. I had it inspected April 2024 with no head gasket issues & the car was at 64,000 miles approximately. So, in 8 months' time, the head gasket was blown & the car is well under 100,000 miles. I have been told that the engine my car has, 1.5L turbo with Honda has had this issue to the extreme that a class action lawsuit has been filed as Honda refuses to do any time of recall or assist with repairs. I literally had to drive with my 4 ways on to avoid being hit in an intersection due to the inability of my car to accelerate. the federal safety agency needs to investigate Honda & determine if they are defrauding consumers by refusing to issue a recall due to this common & dangerous issue. I have owned 7 hours in the 30 years I have had a driver's license & never once had a head gasket issue or any issues to this extreme. I have never replaced a head gasket in any car that I have owned.
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.
