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…

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…

Head gasket blown on engine. Burned off coolant so no leaks detected and just showed high temperature to pull over and let engine cool. Could have cause engine fire and/or disabled vehicle while on road. Very expensive fix and dealers who were contacted said theyâve had multiple vehicles repaired for same issue. Online is widely reported problem with this make and model and among the different trim types all same problems

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…

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 70â75 mph on the freeway. This caused a sudden, dangerous drop in speed, forcing me to maneuver through high-speed traffic to reach the…

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:…
