2019 Honda Accord Hybrid problems

“The vehicle has a documented, severe manufacturing defect involving a cylinder head gasket leak under Honda Service Bulletin 26-006. A certified technician at Honda East Cincinnati confirmed the head gasket leak in writing on September 9, 2026. Prior to this, an independent facility pulled code P0302 (Cylinder 2 Misfire) and used a digital borescope to capture video proof of liquid coolant pooling inside Cylinder #2. Despite written documentation from both facilities confirming an active internal engine leak, American Honda Corporate and the dealership are refusing to honor the warranty extension. They are requiring me to continue driving an unstable vehicle until it actively throws a code on a proprietary dealership scanner. Forcing a consumer to drive a vehicle with a known, documented internal coolant leak risks sudden engine seizure, overheating, and catastrophic stalling on public highways, creating a severe and preventable crash hazard.”

“Vehicle was being driven on the highway when suddenly engine hesitated and started stalling. Speed was reduced from around 65MPH down to the low 40s. Cars were stacking up behind and passing, causing potential hazardous conditions. Vehicle was taken to a mechanic shop and diagnosed with misfiring, after reading OBD II with many alerts coming on. Further diagnostics revealed cylinder head gasket was leaking coolant into engine, as shown by borescope images. This is a known problem on 2018-2020 Honda Accords with both 1.5T & 2.0 engines. The multiple alert messages started to come on a few weeks ago, but the engine hesitation and stalling just started this week. At first we suspected a 12V battery issue, but testing confirmed battery was at 12.8V with no issues.”

“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…”

“The contact owns a 2019 Honda Accord. The contact stated that occasionally, while attempting to start the vehicle, the vehicle took an abnormally long time to start. The contact stated that occasionally while driving at various speeds, the vehicle experienced a light shudder before losing automotive power. There were no warning lights illuminated. The vehicle was towed to a local dealer where the vehicle was diagnosed, and the contact was informed that the fuel pump was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The approximate failure mileage was 54,000.”

“Vehicle stalled and had a power system failure requiring driver to pull off to the side of a road that blocked traffic. The acceleration/drive function no longer worked. The vehicle displayed a POWER SYSTEM PROBLEM message on the dashboard and showed "DO NOT DRIVE". Vehicle was towed to HONDA dealership and they confirmed the fuel pump needs to be replaced. The vehicle had a replacement of the fuel pump in 2022 as part of a prior recall, but the same component is responsible for this situation four years later. Dealership is quoting 1,931 for repairs and Honda America is refusing to cover repair as they claim the 2022 replacement is not related to this incident. They will not confirm whether the parts supplier in 2022 were changed to account for the expanded recall that is part of an ongoing lawsuit settled in 2026 (to be determined when finalized).”
