2019 Honda Accord Hybrid: check engine light

Filed Mar 6, 2026 · Driver assistance, Electrical · CA

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.

Component that failed was the head gasket. Willing to have vehicle inspected. However this incident occurred roughly 7 months ago at 125k miles. Safety was put at risk due to engine overheating which could've caused a fire. I haven't asked the dealer if they've seen it before however this issue is easy to find on forums for this vehicle. The vehicle was only inspected by the dealer who repaired it, I was told by them they had to send off some part of my engine to honda to ensure it wasn't warped before repairing. The ridiculous part was the only warning I received in my car was engine temp high if you ask me such a major failure should cause the check engine light to come one. I had no other warnings than the temp warning. My vehicle doesn't even have a Guage to display the engine temp. To ensure the listed vin shows the correct model I drive a 2019 honda accord hybrid ex with 133,500 miles.

On January 22, 2025, I was driving at highway speed and suddenly my car seemed to lag in power. It slowed from about 60mph to 40mph and pressing on the gas did not do anything. The Check Engine light began flashing. I felt like it would continue to slow down and it was rush hour. I managed to safely exit the freeway and parked the car. I turned it off, waited a moment, turned it back on. It seemed ok so I drove carefully using back streets to the local Honda dealership. They kept the car for 2 days and ran tests but nothing showed on their computer and they could not replicate the problem. They gave me the car back. I saw another recall today for other models of Honda that have this exact problem. My car has 41700 miles on it. The weather was cold but clear. This is the first time this has happened.

Mid October 2023, we driving on the freeway and the car started to slow down on its own. We could not accelerate to match the speed of cars around us or to get the speed limits in a 55 to 65 zone, making it dangerous for us and others to continue driving on the freeway at extremely slow/low speeds. We towed it the dealership, who said it was defective spark plugs. This car was only 4 years old with extremely low millage and the spark plugs should've last a lot longer. They changed the spark plugs under warranty. Late November 2024, we were getting off the freeway and the check engine light came on but there were no service codes. Everything was running normally except for the engine was making a loud noise. We parked at a shopping center and approximately 30 minutes later, restarted the car and all these messages and icons appeared for: Vehicle stability assistant system problem, Hill start assistant problem, ACC, Collision Mitigation breaking system problem, Road departure mitigation system problem, Emissions system problem, TPMS, Brake system problem, Electric power steering system problem. Towed it dealership and after an hour of diagnostics testing, they said it’s the spark plugs again! Just a little over a year and 2 out of 4 spark plugs are bad again. This is not right. We hardly drive this car and it’s only a little over a year since the spark plugs were replaced and a little over 5 years since we got the car brand new. Spark plugs are supposed to last 10 years or 100,000 miles and we’re not close to either. This time they said it's not covered under warranty and is over $800.

On 6/14/22 and 3/29/23, my 2019 Honda Accord EX Hybrid had engine misfirings which lead to total loss of power on Rt 15 in NY and CT: 6/14/22: Upon entering highway, car bucked during acceleration and lost all propulsion coasting to a stop. Check again light was on and blinking. After reseating gas cap car driven directly to dealer for diagnostic. Car computer did NOT retain any error codes even though engine light was blinking. Dealer did not do any repairs. 3/29/23: Near end of 30 minutes in stop and go traffic, car began to hesitate when inching forward. When accelerating to travel speed, car bucked during acceleration and lost all propulsion coasting to a stop. Check again light was on and blinking. After reseating gas cap car driven directly to dealer for diagnostic. Car computer did NOT retain any error codes even though engine light was blinking. Dealer did not do any repairs. If check engine light indicates get service soon and a blinking light means get it immediately, then there appears to be an issue with Honda's computer diagnostic for not retaining codes. Also the propulsion system for failing which could possibly create safety issues for drivers of this vehicle. I traded the vehicle in for safety purposes and was forced to purchase a new vehicle much earlier than expected.

Hello, I am writing to you about my 2019 Honda Accord Hybrid. This vehicle make and model had over 600,000 safety recalls for the Denso fuel pump. When I Input the vehicle on Honda for recall info, nothing shows up. I took it to a local Honda dealer but they did not check the fuel pump instead told me it was other issues. I was driving my vehicle on the freeway after my first Honda visit and my vehicle suddenly lost power and the check engine light started flashing ( I have videos of this if needed). There was a truck behind me and I almost got hit by the truck which was a significant issue to my safety. I also started to smell gas. These are all signs of a bad fuel pump. I understand that my vehicle does not pop up on the recall with the VIN number but being it the same make and model with similar symptoms, I would like to see what the federal safety agency can do to inform me of the recall as my vehicle possibly might have a bad fuel pump ( which should be covered under this recall).
