Check Engine Light Flashing

A flashing check engine light on a 2012 Hyundai Santa Fe usually signals a severe misfire or condition that can damage the catalytic converter if driven. This is an urgent situation: stop driving if you notice serious vibration, loss of power, or a pronounced smell of fuel. At Herb Chambers Hyundai of Auburn in Auburn, MA, our technicians prioritize safety—conducting immediate diagnostics to locate misfires, ignition faults, or fuel delivery problems. We check battery and charging condition as part of the inspection because weak batteries or poor charging can exacerbate symptoms or trigger codes. Our dealership maintains genuine Hyundai parts in inventory and offers transparent pricing, warranty coverage where applicable, and service financing to help you act immediately without financial stress.

We also run a thorough emissions and catalytic converter assessment, since unresolved misfires can lead to significantly higher repair costs. Choosing Herb Chambers Hyundai of Auburn ensures certified Hyundai technicians perform the repair with OEM parts and proper calibration, preserving reliability and resale value.

2012 Hyundai Santa Fe Check Engine Light Codes

Common codes for the 2012 Hyundai Santa Fe include P0420 (catalyst efficiency), P0300 (random/multiple misfires), P0171/P0174 (fuel trim—lean), and P0135 (oxygen sensor heater). Left unchecked, each can escalate costs: a P0420 ignored may lead to catalytic converter replacement (thousands of dollars), while untreated misfires (P0300) can ruin the converter and stress the engine, producing progressive damage and fuel waste. Lean fuel trim codes can indicate vacuum leaks or fuel delivery issues, reducing fuel economy and accelerating wear. Herb Chambers Hyundai of Auburn provides complete code interpretation, part-fit verification, and repair plans that highlight immediate savings and long-term ownership value. We replace parts only when necessary and provide written estimates showing how prompt dealer service avoids compounding expenses and downtime.
