2016 Hyundai Genesis Check Engine Light Codes

The 2016 Hyundai Genesis at Larry H. Miller Hyundai Peoria frequently reports a handful of diagnostic trouble codes: P0420 (catalyst system efficiency), P0300 (random/multiple misfires), P0171 (system too lean), P0455 (EVAP large leak), and P0135 (O2 sensor heater). In Peoria, AZ we see these codes across vehicles from routine wear to neglected maintenance. Costs from ignoring these codes escalate quickly — a P0420 left untreated can lead to a failed catalytic converter that costs thousands to replace, while persistent misfires (P0300) can damage pistons and the catalytic converter and lead to towing expenses and downtime. At Larry H. Miller Hyundai Peoria our certified technicians use OEM diagnostic tools and factory parts to identify the exact cause, preventing unnecessary part swaps and achieving durable repairs. Choosing our dealership often costs less than independent shops when you factor in fewer follow-ups, honest estimates, warranty coverage, and the long-term savings of using OEM components. To protect performance and avoid inflated future repairs, schedule service and check available service specials before you arrive.

Miller Hyundai Peoria our first priority is safety and limiting collateral damage: we’ll evaluate the vehicle immediately, prioritize necessary repairs, and communicate transparent pricing and timelines.
