2019 Honda Accord

On April 14th, 2026 we were driving on the road, the car overheated. We shut it off, sat for a few minutes. Started driving again and had to sit in roadwork, within 1 minute the car started to overheat again. We pulled into the gas station, checked coolant levels, all fine. We let the car sit for 20 minutes or so, we tried to turn the car on and the engine started sputtering and all dash lights came on. We got the car towed to a shop, they looked over the car and told us that coolant had leaked into the cylinders and the head gasket was blown but there was no leak in any of the coolant areas. They quoted us over $7000. So we are out of a car while it’s at the shop waiting to get fixed.

The contact owns a 2019 Honda Accord. The contact stated that while at the stop sign to access the feeder road, while accelerating, the lights started flashing on the instrument cluster. The vehicle failed to accelerate above 5 MPH. The driver turned on the hazard lights, made a U-turn, and pulled over a block away at a stadium. The vehicle was turned off. The contact retrieved DTC: P0301, P0302, P0304, and P0300. A code reader was used to erase the codes. The vehicle was restarted and driven as designed. While the contact’s wife was driving, the vehicle failed to exceed 5 MPH. The vehicle was taken to the dealer for a routine recall repair on the fuel pump and software. The dealer informed the contact that the failure was not related to a recall. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 85,000.

Subject: Vehicle Safety Defect Report – Brake Failure and Collision Mitigation System Malfunction To the National Highway Traffic Safety Administration, I am filing a safety defect complaint regarding a Honda vehicle that experienced sudden brake failure and a suspected Collision Mitigation Braking System (CMBS) malfunction, resulting in a crash on [date]. Incident Summary: • Brakes suddenly stopped responding • CMBS appeared to activate or interfere with braking • No obstacles or hazards present • Loss of control and collision • Vehicle purchased from Karplus Warehouse (salvage title) • Dealer did not disclose braking or safety system issues This malfunction created a dangerous safety hazard. I request that NHTSA document this incident and evaluate whether similar complaints ---

Head gasket failure was diagnosed by a certified dealer. The only symptom leading up to the failure was slight hesitation when starting the vehicle. Safety issues include sudden engine power loss, engine fire, overheating, and reduced visibility from thick white smoke, and the potential loss of steering or braking power.

Head gasket 2 has failed on my vehicle.

My car started getting hot, began to overheat. I was on my way home on freeway. Second lane from slow lane. My car began to loose power, I could no longer excelerate. There was a big rig coming up behind me he was not slowing down as he got closer began honking I was trying to flag him that I could not move, as I was trying it started to go like 5 miles per hour where i began slowly to get over, cars in the other lane slowed down. Big rig went around me and avoided any collision. Thank God. I slowly made my way home on the streets with heater blasting. I towed my car to the dealer. I was told, my head gasket needed to be replaced, more than likely I would need a knew engine. Dealership said it was because when taken my car in for service I did not bring to the dealership. Cashier told me that there have been several incidents as mine.To my surprise I googled 2019 Honda Accord engine, and there were many with the same issue same car same year. Yet no recalls! I was lucky not to have been killed or have caused a multiple car collision. Are we waiting for someone to be killed to recall these engines. I missed several days of work, borrowed cars and rented a car to get back and forth to work not to mention the tramatic experience of a big rig coming at you honking on a FREEWAY. A week prior to this incident, my lights on the dashboard came on. I did call the dealership to set up an appointment. At that point they were no signs of overheating. I have taken my care in faithfully for oil changes where all fluids are checked, i was not told not once that any fluids were ever low, last visit was approx 5 months ago. I have called to have them send me all receipts. However in hindsight I do not need theses records as it has been proven by other people they have had the same experience. We are not talking about a faulty air conditioner we are speaking of an engine, in my case power failure. In the even records of oil changes and dealership diagnosis is required. I can email.

The contact owns a 2019 Honda Accord. The contact stated that while operating the vehicle, several unknown warning lights illuminated. Additionally, the tire pressure monitoring system, Emissions system, ABS, and electric power steering warning lights were illuminated. Additionally, there were alerts for the adaptive cruise control, collision mitigation, and road departure systems displayed. The vehicle was taken to a mechanic, where it was diagnosed with fuel injection failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 137,708.

The vehicle suddenly braked on its own without any obstruction, causing a violent stop and injury. I took it to the nearest dealership to check for a recall. They said there wasn't a recall for this VIN, although online searches show this as a known defect for 2018-2020 Honda Accord Collision Mitigation System.

head gasket failure with less than 80,000 miles.

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle stalled. The check engine warning light was intermittently illuminated. The contact restarted the vehicle to correct the failure. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The contact related the failure to NHTSA Campaign Number: 23V858000 (Fuel System, Gasoline); however, the VIN was not included in the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 94,000.

I was told the best thing to do was report it here. Our son was driving his 2019 Honda Accord and suddenly everything on his dashboard lit up. Was told it is a blown head gasket. We were also told that the shop has had over 81 Accords in with the same issue. They said Honda is trying to sweep it under the rug rather making a recall. We were told this is what they see: The head gasket material between cylinders is very tiny, any minor disturbance will cause coolant to leak into the cylinder. Usually failures are happening between cylinders 2&3 where the material is the thinnest. 2) Honda is really trying to get a lot of power out of this small engine with the inclusion of the turbocharger. Higher octane fuels are needed to prevent premature detonation / knock, especially with forced induction (turbo charger). You can still run the car using 87 octane, but the chances of problems like a blown head gasket happening increase. 3) The head bolts that keep the engine head to the engine block are not strong enough. These bolts are torque to yield at around 50 ft lbs (if that). There have been instances where these bolts don't have enough clamping force to withstand the pre-detonation. This force causes the head to jump and the bolts to stretch. The heat from the combustion in the cylinder is no longer contained, which warps and damages the head gasket over time, leading to its failure. It was suggested to use ARP studs which we were told are a higher quality than the OEM Honda head bolts and have a stronger clamping force. Our son ended up stranded 3 states away with this issue that we then learn is VERY common yet there are no recalls.

Car lost power on freeway, had the car towed to local Honda. After several hours of sitting at dealership and talking to several different employees. One employee comes back to tell me the head gasket was blown and needed repaired. And that this is a common issue he has been seeing in this make/model of car.

The contact owns a 2019 Honda Accord. The contact stated that while driving at an undisclosed speed, the vehicle unexpectedly went into LIMP Mode, with several unknown warning lights illuminated. The vehicle was taken to an independent mechanic, where it was diagnosed with fuel pump failure. The contact was informed that the fuel pump needed to be replaced. The vehicle was not repaired. The vehicle was then taken to the dealer but was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 130,000.

My 17 year old drives this car and has suddenly stalled and gone into limp mode 3 separate times (twice on busy highway) with no warning or codes provided. Most recently the vehicle alerted of overheating. After a couple trips to mechanic it was determined that head gasket is going out. It seems that this is a very common problem with this vehicle and an extreme safety hazard. Especially with young drivers as it sent my daughter into panic and nearly caused accident on initial breakdown.

Multiple warning lights on dashboard. Vehicle runs perfectly fine with brand new battery and spark plugs but still has 9 random warning lights coming on.

The turbo! Code P0299! Hundreds of thousands of Americans going through the same issue all their lights are flashing on their dashboard with these 1.5 T engines

I own a 2019 Honda Accord 1.5L with 112,985 miles. The vehicle developed a blown head gasket with coolant leaking into Cylinder 3. The failure was first confirmed via a combustion leak (CTR) test performed by an independent Honda specialist (Hond-Auto Specialist) on March 2, 2026, and later confirmed by an authorized Honda dealership (Vandergriff Honda, [XXX] ) via borescope inspection on March 23, 2026. Repair estimate is $4,799.81. This is a known defect. American Honda Motor Co. issued two internal Priority/Action Required memos to all Honda Service Managers and Advisors — April 2023 and August 2024 — confirming they were actively investigating this identical head gasket failure on 2018-2022 Honda Accords equipped with the 1.5L engine. Despite this internal investigation spanning multiple years, Honda has not issued a recall. A federal class action lawsuit [XXX] v. American Honda Motor Co., Inc.) has been filed alleging Honda knew of this defect before these vehicles were sold. I am requesting NHTSA investigate and compel Honda to issue a formal recall for all affected 2018-2022 Honda Accord 1.5L vehicles. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Description of Incident: 1. Component/System Failure: The engine cooling system and head gasket failed. A certified shop has confirmed coolant intrusion and a failed leak-down test on Cylinder 2. The vehicle is available for inspection upon request. 2. Safety Risk: My safety and the safety of my family and other drivers were put at extreme risk. On March 1, 2026, the vehicle suffered a sudden loss of motive power while traveling at 70 MPH on the freeway. The car dropped to 15 MPH instantly, forcing me to maneuver across active lanes to a narrow shoulder with almost no space. I was nearly hit by high-speed traffic. This has occurred over 8 times since 2023. 3. Confirmation by Service Center: The problem has been reproduced and confirmed by an independent service center On Site Lube Auto & Tire. They utilized a borescope and leak-down test to verify the internal engine failure. 4. Inspections: The vehicle has been inspected by a certified independent technician. I am in the process of notifying the manufacturer (Honda) of these findings for their inspection and accountability. 5. Warning Lamps & Symptoms: Prior to the total power loss, the vehicle displayed engine temperature warnings and "check engine" lights. These symptoms first appeared approximately 8 months after purchase in 2023 and have progressively worsened, leading to the current engine failure. 6. Additional Notes: This failure is identical to issues cited in active class-action lawsuits regarding Honda's engine defects, affecting both standard and Hybrid models. I am communicating via written report/email for documentation and accessibility purposes.

The contact owns a 2019 Honda Accord. The contact stated that while starting the vehicle, there was a choking sound coming from the vehicle, and brake pedal went to the floorboard. The vehicle was turned off and while restarting the vehicle, the Lane Departure, TPMS, Brake System, Brake Hose, Brake Performance Reduced, and other warning lights were illuminated. The contact was able to drive the vehicle. The vehicle was not taken to a dealer or independent mechanic to be diagnosed or repaired. The manufacturer was not informed of the failure. The failure mileage was unavailable.

City street driving speed < 35-40 mph, engine began rough idling at stop light after traveling just 1/8 mile. After driving less than 1 mile on level ground, engine slowed and would not accelerate above 20 mph. After another mile or so, increasing uphill grade caused speed to slow to 12-14 mph. Stepping on gas caused car to slow down even more, with shaking and jerky stop-start of vehicle. Maintaining 10-12 mph permitted vehicle to continue uphill climb for a few more miles so I could reach home. Downhill coasting was smooth with no gas pedal acceleration. Overnight parked in garage, and no problems driving vehicle to local independent auto mechanic. They were able to duplicate problem after 2 days and multiple test drives. Diagnosed permanent and temporary engine codes: misfires of cylinders 1 and 4 with ignition coil malfunction, misfires of cylinders 1, 2, 4, and random misfires. Also permanent codes: antilock brake ECM Failure, electric power steering vehicle stability assist System Malfunction, electric servo brake electric power train System Malfunction. Mechanic removed coils and spark plugs, found cylinder 4 has moisture. Coils, plugs cleaned and re-installed. Honda Dealer unable to duplicate problem after 3 days.
