2019 Honda Accord Engine Problems

Vehicle caused a SEVERE drivability condition while at highway speeds by sputtering, losing power and auxiliary driver's systems becoming degraded. We were able to drive the vehicle in limp mode to a near service station. They ran diagnostics and determined that there were multiple secondary events affecting the ADAS system. They also checked the battery and determined it was marginally good. We managed to drive the vehicle in degraded mode to our home and we changed the battery the following day. Upon doing so, all affected systems became available again and the vehicle's driveability profile was restored. This behavior is incredibly unsettling and UNSAFE. A vehicle that is so sensitive to electrical fluctuations should have BETTER warning systems that would prevent, or at least advise the driver, that an unsafe condition will occur unless the battery is promptly replaced. This behavior could easily cause an accident if the driver is unprepared to react to the vehicle sudden and unpredictable shutdown of engine power and safety systems. This needs to be investigated and corrective measures need to be promptly proposed to affected vehicle.

I was driving on the highway in Michigan, the speed limit is 70 mph. All of a sudden, I noticed that my car acceleration was not working. It ended up my engine misfired and in doing so, I could not go more than 20 mph on the actual highway!!! it was absolutely terrifying, even when I put on my emergency lights, I had to find a place to safely pull aside. I still had to pull out in front of someone to try to get off the exit, so pulling out in front of someone at 20 mph on the highway was petrifying. Once, I finally was able to pull into a safe place. I immediately called my insurance company and Honda about the misfiring of my engine. My car was then towed to a Honda dealership, where technicians diagnosed a blown head gasket caused by coolant leaking into a cylinder. The only warning light was the “check engine” flashing light when I was unable to drive more than 20 mph. My vehicle went limp. The repair required replacement of the head gasket at significant personal expense About $6k +.

My car began to not turn on. Took it to the dealership, was told it was the turbocharge being loose. They saw coolant leaking. Paid for the fix. Few days later, car lost power and entered lint mode. Took it back and with simple camera work they check the gasket was leaking. Told that since the turbo before wasn’t working as intended, the gasket became thin. Repairs are above 6k, had no warning lights. Seems this is a common issue.

The first problems began in March 2026. No warning lamps turned on. My car began jabbing as I accelerated and a couple days after when I was breaking too. The first mechanic said it could be a coil but the problem didn’t stop after changing it. I then took it to Honda and they confirmed that it was a blown head gasket and that they were surprised no warning messages had appeared. I took it to Empire Automotive to get it fixed, I paid 5K to get it fixed. Three months after getting it fixed I am getting on the freeway and my car stops accelerating. The car behind me had to swerve on the side to avoid hitting me. I was able to move over to the side. Again no warning messages had shown up. I took it back to the mechanic and they confirmed the head gasket had blown out again.

I received a warning light indicating my car was reaching maximum internal temperature. I immediately shut off the car, then took it to the Honda service center the next morning. They did an inspection and determined there is a leak in my head gasket at cylinder 3. There were no warnings prior to the time of failure. I had recently had my coolant flushed as part of general maintenance and I never missed an oil change. Vehicle inspections at the Honda Service Center regularly showed no issues.

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.

Incident

Jun 19, 2026

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 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.

Incident

Apr 30, 2026

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)

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

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.
