2024 Hyundai Elantra Check Engine Light Reset

The process to reset the check engine light on a 2024 Hyundai Elantra is straightforward when handled by certified technicians at Larry H. Miller Hyundai Peoria in Peoria, AZ. While some consumers may see temporary resets from a battery disconnect or an OBD-II scanner, those quick fixes do not address underlying faults and can mask problems that later cause expensive damage. Our team performs a full code read with OEM-grade tools, identifies pending or active trouble codes, explains the root cause in plain language, and provides a written estimate before any work begins. We use Hyundai-approved parts and follow manufacturer service procedures — so resets are permanent and supported by warranty when applicable. Choosing dealership service offers transparency: clear pricing, documented repairs that maintain warranty coverage (repairs covered under warranty must be performed at a certified dealership), and the peace of mind that comes from factory-trained technicians. We also offer flexible service financing to get necessary repairs done now and pay over time. To avoid repeating visits and protect your vehicle’s longevity, schedule service with our service team, or review our current service specials for added savings.

2024 Hyundai Elantra Check Engine Light Codes

Common check engine light codes for the 2024 Hyundai Elantra that we see at Larry H. Miller Hyundai Peoria include P0420 (catalyst system efficiency), P0300 (random/multiple cylinder misfire), P0430 (catalyst system low efficiency bank 2), and P0171/P0174 (system too lean). Left unaddressed, a P0420 or P0430 can lead to failed emissions tests and more costly catalytic converter replacement; P0300 misfires can cause drivability issues and damage to ignition and catalytic components; lean codes can reduce fuel economy and accelerate engine wear. Our technicians diagnose the precise cause, present repair options, and explain both immediate and long-term costs so you can make an informed decision. Because we install OEM parts and follow Hyundai procedures, many customers experience lower total ownership costs versus repeated fixes from independent shops. We also document all work for warranty continuity — repairs covered under warranty must be performed at a certified dealership — and offer service financing to ease payment. For convenience, you can schedule service online and check current offers on our service specials. Visit Larry H. Miller Hyundai Peoria to experience rapid diagnostics, certified expertise, and customer-focused service in Peoria, AZ.
