What 653 owners told NHTSA about the 2019 Honda Accord Fhev

My car was stalling on the highway not going over 40, a perfectly maintained 88k mile car that is stock and only used for work and light leisure. The weak engine head gasket is to blame for coolant seeping into cyclinder 3. A very known defect with the 1.5 turbocharged engines recently. The safety of me and passengers was at risk because that’s a 50mph+ highway and my car didn’t go to 50. Yes the problem was confirmed by dealership / manufacturer. Zero warning lights to this day.

I can’t drive the car normal have to drive 60mph or under the radio went out and Honda can’t seem to figure out why so I can’t connect CarPlay. Myself and my kids are at risk due to the car randomly cutting off at any given time. I took it to Honda twice and my car has not been checked they constantly say they’re backed up but don’t have any rentals in stock. Can’t get the car inspection done because the lights are on. No they’re were none the light randomly popped up and said it was a camshaft sensor piece I got that change and the lights are still on. Took it to a mechanic to have it diagnosed and they’re stating it’s the turbo. Which is pretty annoying the car maintenance is don’t regularly and I’ve only had it for a year and a half.

I am reporting a premature and dangerous failure of the engine head gasket on my 2019 Honda Accord Sport (1.5L Turbo engine, 68,220 miles). While driving, the vehicle suddenly lost power due to severe engine misfires. Simultaneously, the dashboard experienced a total cascade of safety system failures, illuminating warning lights for the Check Engine Light, Electric Parking Brake, Traction Control (VSA), Road Departure Mitigation, and Adaptive Cruise Control. The vehicle currently in the authorized honda dealer where technicians officially diagnosed a blown head gasket leaking coolant into Cylinder 3. This is a widespread, well-documented manufacturing defect with Honda's 1.5L Turbo engines. I request that the NHTSA launch a formal safety investigation into American Honda for these premature head gasket failures to force a mandatory safety recall.

The contact owns a 2019 Honda Accord. The contact stated that on several occasions while driving at undisclosed speeds, the vehicle started shaking abnormally. Occasionally, while depressing the accelerator pedal, the vehicle jerked hard. Additionally, the contact stated that the message "Emissions System Failure," "Engine Overheating - Turn off Immediately," and other unknown messages were displayed, with several unknown warning lights illuminated. The vehicle was taken to an affiliate dealer where it was diagnosed and determined that the head gasket needed to be replaced, and the engine needed to be disassembled to determine the cause of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 120,000.

The head gasket has failed and Honda knows this is an issue. There is a lawsuit in California about the head gasket failing. With it failing the whole engine is at risk for being ruined. This is going to cost $4000-$10,000 for people to fix depending on the damage it causes the engine. I personally lost acceleration on the freeway while going up a hill and everyone around me going 65-80 mph. I have 11 warning lights on my car right now and it started overheating today with a warning stating that the engine was hot and to stop driving immediately. We had to get towed to the mechanic for the 2nd time this week. When searching online I realized this was a known issue and about the class action lawsuit.

I have a 2019 Honda Accord Sport 1.5. I was driving on the freeway last week and my car did not allow me to accelerate anymore. Car went to an unsafe highway speed and it was hard to get to a shoulder where can safely stop. I felt my safety was compromised by this issue. All the warnings appeared on my dash and all the lights went on. No warnings prior to this problem. I am needing a new head gasket and repairs are estimated over 5K. I know there is a class action lawsuit against Honda because this issue is extremely common. I need help. I can’t afford these repairs and I depend on my car for transportation to work and child care daily. Please hole Honda accountable for this is very dangerous and very common.

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

Vehicle: 2019 Honda Accord Sport 1.5L VIN: [XXX] Mileage: Approximately 122,497 My vehicle experienced a cylinder head gasket failure accompanied by coolant intrusion into the engine cylinders, injector-related issues, fuel trim failures, and cylinder misfires as diagnosed by an authorized Honda dealership. Prior to diagnosis, the vehicle experienced engine performance concerns associated with the misfire condition. The dealership documented historical misfire events and coolant intrusion into the combustion chambers. I am submitting this complaint because I am concerned that injector-related issues, engine misfires, coolant intrusion, and cylinder head gasket failures may represent a recurring condition affecting similarly equipped vehicles. Engine misfires and coolant intrusion can potentially result in reduced engine performance, loss of power, unexpected vehicle behavior, or engine failure while the vehicle is being operated. I request that NHTSA review this issue and determine whether a broader investigation is warranted. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

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

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

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

VEHICLE: 2019 Honda Accord LX SUMMARY OF SAFETY DEFECTS & FAILURE: My vehicle is experiencing severe, dangerous mechanical and electrical failures identical to existing national safety recalls, yet my specific VIN is being excluded by the manufacturer. 1. FUEL SYSTEM FAILURE & ENGINE STALLING: The vehicle is experiencing sudden engine stalling and failure to start due to a defective low-pressure fuel pump. This matches the exact failure profile of NHTSA Recall Numbers 23V-858, 21V-215, and 20V-314 (Honda Campaigns KGC/KGD). This defect causes the vehicle to lose power unexpectedly, creating an immediate crash hazard on active roadways. 2. BODY CONTROL MODULE (BCM) DEFECT: The vehicle is suffering from critical electrical disruptions, resulting in erratic component failures including [mention any specific symptoms you have, e.g., malfunctioning windshield wipers, defrosoter failure, rear-view camera blacking out, or power window errors]. This perfectly mirrors the systemic programming defect outlined in NHTSA Recall Number 20V-771 (Honda Campaign X95). DEALER DIAGNOSIS & MANUFACTURER DENIAL: I have taken the vehicle to an authorized Honda dealership multiple times. - In June 2025, the BCM software issues were initially dismissed by the dealer as a general electrical problem. - A subsequent comprehensive diagnostic confirmed the fuel pump and BCM failure, resulting in a repair estimate of $4,688. The dealership refused to cover the repairs under the safety recalls, citing that my VIN is not currently flagging "open recalls" in their corporate database. When referred to American Honda Motor Co. Corporate Customer Support, corporate summarily dismissed my complaint and refused any cost assistance or repair remedy, despite their clear knowledge that these exact defects plague the 2019 Accord LX model year. Because the manufacturer is utilizing restrictive VIN range loopholes to evade financial accountability for known safety hazards, I am filing this complaint

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

Upon recent repairs completed by an Official Honda licensed dealership for the fuel pump due to the related issue of stalling, misfiring, insufficient fuel economy and safety concern. My vehicle has continued to stall, misfire or idle extremely rough. Upon local investigation the error code P0203 and P0303 have populated as the most recent issue. No longer allowing me to drive the vehicle as it remains in limp mode. Previously error codes such as P0304 and P0302 as well as the associated error codes for the Injector Circuits indicating “open” have previously been detected intermittently and now permanently. In previous events within the last 3 months I have been stranded on highways due to the same stalling, misfiring and limp mode issue after I have previously been inspected by a Honda dealership and promised the issues would resolve. Unfortunately driving at respectable highway speeds and even local city limits my safety as well as my child and spouse’ safety have been put at risk due to the sudden deceleration caused by consistent misfires or limp mode effect which can cause me to have a collision with no warning. I have nearly been in 3 accidents due to this persistent issue.
