Check Engine Light Flashing

The check engine light flashing on a 2019 Honda Accord is a warning that immediate attention is needed. A flashing MIL (malfunction indicator lamp) typically indicates a severe misfire that can allow unburned fuel into the exhaust stream, risking catalytic converter damage and higher repair costs if ignored. At Larry H. Miller Honda Boise, our factory-trained technicians prioritize safety and long-term value: we inspect ignition coils, spark plugs, fuel delivery, and sensor inputs with OEM diagnostic tools to identify the cause and prevent collateral damage. Choosing dealership service often costs less than independent shops when you factor in accurate diagnostics, correct OEM components, and warranty protection for covered repairs—meaning fewer repeat visits and lower lifetime ownership costs. We also offer service financing so you can address urgent repairs now and pay over time. Browse current service specials and schedule service online to get prioritized care and peace of mind.
