2017 Hyundai Sonata Hybrid Check Engine Light Codes

The diagnostic trouble codes most commonly seen on a 2017 Hyundai Sonata Hybrid in Albuquerque include P0420 (catalyst system efficiency below threshold), P0135/P0136 (oxygen sensor heater circuit or O2 sensor issues), P0300 (random/multiple cylinder misfire), and P0440 (EVAP system leak). Ignoring a P0420 or persistent O2 sensor fault can accelerate catalyst failure — replacing a catalytic converter can exceed $1,000, while replacing a failed oxygen sensor costs substantially less when addressed early. A P0300 misfire left unresolved risks internal engine damage, lost fuel economy, and elevated emissions; timely repairs prevent higher labor and parts costs down the road. At Larry H. Miller Southwest Hyundai Albuquerque we identify the specific code, diagnose root causes with OEM-level tools, and outline price options so you see immediate savings and long-term value. Our certified technicians follow Hyundai procedures, and we stock common OEM parts to speed repairs; that means fewer return visits and lower total ownership cost. To book a visit, you can schedule service and check available service specials that further reduce out-of-pocket expense.
