NHTSA Complaint #11685056 — 2019 HONDA ACCORD

While driving my 2019 Honda Accord, the engine began misfiring and losing power. A diagnostic scan showed misfire codes (P0300–P030X). The issue was traced to coolant leaking into the combustion cylinder due to a head gasket defect. This caused engine hesitation, reduced acceleration, and risk of stalling while in traffic. I have learned that Honda has issued a Technical Service Bulletin (TSB) for this issue, but no recall. This is a serious safety concern because loss of power or stalling could cause an accident, especially at highway speeds or during turns/intersections. The repair is extremely costly for owners, and the defect appears to be widespread in 2018–2019 Accord models with the 1.5L turbo engine. This should be investigated and addressed as a recall to protect drivers.
