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.

I brought my 2019 Honda Accord to dealer for safety recall for something with the fuel system. Since then, I've been having car problems with acceleration, car jerking, and numerous dash lights coming on along with the check engine light. Had a few incidents where my vehicle was not functioning properly and would break down. Had my vehicle towed once since getting my vehicle back from dealer due to recall. Please advise and please help.

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.

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.

1. Component: The engine head gasket and the combustion system (specifically Cylinder 2). Specifics: A leak-down test confirmed a failure in Cylinder 2, leading to coolant intrusion. This was initially masked by a water pump code, but after the water pump was replaced and the code returned, a borescope confirmed "clean" pistons (steam-cleaned by coolant) and tap scarring. Availability: Yes, the vehicle and all diagnostic records are available for inspection. 2. Emergency Maneuvers: On multiple occasions, the car entered "Limp Mode" while driving 70-?"75 mph on the freeway. This caused a sudden, dangerous drop in speed, forcing me to maneuver through high-speed traffic to reach the median/suicide lane. Stranded: The vehicle overheated 5 times in one trip, leaving me vulnerable on the side of a busy freeway. 3. Yes. An independent shop confirmed the failure via a leak-down test, a borescope inspection, and physical analysis of the spark plugs. They confirmed that despite the computer throwing a water pump code, the mechanical failure is the head gasket. 4.Status: It has been inspected by an independent service center. I am now using their findings to pursue a lawsuit/claim against Honda for selling a vehicle with a pre-existing internal engine defect. 5. Timeline: Symptoms began in April 2024 (two months after purchase). Initial Signs: An "Emission System" warning light appeared. The diagnostic code indicated a water pump failure, which was replaced in April. Recurring Symptoms: In November, the car suffered multiple misfires and "Limp Mode." In March, the "Emission System" light and the same water pump code returned, but the shop confirmed the pump was functional and the true cause was the head gasket leak into the cylinders.

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.

Approximate date (around January 2026), location (e.g., Newburgh, NY area), and circumstances (e.g., during normal driving). No crash/injury mentioned in my case, but note if it stranded I, required towing, or felt unsafe (e.g., potential for sudden power loss). While driving, all dashboard warning lights came on suddenly. The vehicle experienced rough running/misfires. Dealer diagnosed low coolant, pressure tested the system, and confirmed coolant intrusion into cylinders 2 and 3 due to head gasket failure. This required full head gasket replacement (parts/labor ~$4,567 total before any goodwill). No external leaks noted initially. Concerned this could cause engine stall/overheat while driving, posing a safety risk.-?? Dashboard lights, possible misfire codes (if any DTCs like P0302/P0303 were pulled), low coolant without visible leaks. dealer diagnosis (Morehead Honda? from Eric Koller), repair done/recommended, cost, and that American Honda provided 35% goodwill (shows it-??s out-of-warranty but recognized issue) Only 91000 miles on the vehicle.

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.

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.

- Madison, TN, USA

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 recurring and known issue with this vehicle.
