NHTSA Complaint #11624265 — 2019 HONDA PILOT

Problem: Emissions System Problem I am reaching out to request an expansion of the coverage provided by Service Bulletin 21-010 to include vehicles of the same model year, trim level, and similar specifications—even if they fall outside the currently specified VIN range. I believe this case is reason for Honda to consider expanding the coverage due to the potential for this issue to affect additional vehicles beyond the initially designated VINs. 1. Defects Are Not Always VIN-Specific Manufacturing flaws can affect an entire batch of production, not just a specific VIN range. Issues related to parts, assembly processes, or design flaws found within the currently affected VIN range could very well extend to vehicles produced around the same time, even if they lie outside the VIN specifications. By limiting coverage strictly to the designated VIN range, Honda may inadvertently overlook other vehicles that share the same defect. 2. Shared Components and Engineering Design While variations in parts and tolerances are expected, vehicles with the same model year and trim level often share critical components and similar engineering specifications. This makes it likely that other vehicles outside the specified VIN range could also be affected by the same defect. Given that design, assembly processes, and parts are often consistent across a model year, expanding the coverage could better account for possible common manufacturing issues. 11-9-24 - Honda ran their analysis determined the following issue: P0430 (FRONT BANK CATALYST SYSTEM EFFICIENCY BELOW THRESHOLD [BANK 2]) BULLETIN OUT FOR FUEL INJECTORS REPLACEMENT FIRST. PERFORMED CYLINDER AF TEST AND FAILDER NUMBER 1 AND 6. REPLACE FUEL INJECTORS AND PERFORM AF TEST AGAIN. MAY NEED CAT. CONVERTER FRONT. On 11-8-24 Honda Customer Support refused to include this car in the recall. Vehicles with the same year, model, and trim level should be included in the service bulletin, based on the systemic nature of the defect.
