NHTSA Complaint #11685705 — 2014 HONDA PILOT

My 2014 Honda Pilot has intermittent engine misfires (DTCs P0301–P0304) caused by piston ring failure. The defect leads to rough running, sudden loss of power, and unsafe driving conditions. On October 24, 2024, Crown Motors Honda in Holland, MI confirmed piston ring failure on cylinders 1–3, with oil wash and fouled spark plugs. The vehicle had to be towed when my wife was driving due to loss of power. This vehicle is driven daily by my two high-school sons, often with my youngest as a passenger. The misfire and power loss create dangerous situations when merging, accelerating, or driving in traffic. Honda has refused to perform warranty repair unless the check engine light (MIL) is currently illuminated, even though their own Technical Service Bulletin 25-060 explains that stored codes and spark plug inspection are sufficient for diagnosis. Waiting for the CEL to reappear puts my children at risk of sudden failure. The defect has been confirmed by a Honda dealer, and is consistent with known issues covered by Honda warranty extensions and the Soto v. American Honda settlement. The problem is reproducible, poses an ongoing safety hazard, and remains unresolved.
