NHTSA Complaint #11707133 — 2016 HONDA PILOT

The vehicle experienced a sudden engine malfunction while being driven at highway speeds in the carpool lane under normal conditions. The engine began knocking and misfiring, followed by a significant loss of power. There were no warning lights, oil pressure alerts, or messages prior to the failure. The loss of power and engine knocking made it difficult to safely cross multiple highway lanes from the carpool lane to reach an exit, creating a serious safety hazard in active traffic. The driver exited the freeway as soon as safely possible, parked the vehicle, turned the engine off, and had it towed to prevent further damage or risk. The vehicle was towed home and then towed the following day to an authorized Honda dealership for inspection. The dealership confirmed the failure was caused by internal engine damage due to a connecting rod bearing failure, resulting in a misfire on cylinder 4. This diagnosis was confirmed by the dealership, and the vehicle remains available for inspection. The vehicle has been regularly maintained, including routine oil and filter changes. There was no indication of oil starvation, overheating, or neglect prior to the failure. The engine failure occurred suddenly and without warning. There is an existing recall and an active federal investigation related to connecting rod bearing failures in certain 2016 Honda Pilot vehicles. While this vehicle’s VIN has not been officially included, the failure mode, symptoms, and dealer-confirmed diagnosis in this incident appear consistent with the issues described in those actions. Sudden internal engine failure at highway speeds presents a serious safety risk due to unexpected loss of power in traffic. This complaint is submitted to document a similar internal engine failure with no warning and its associated safety implications.
