2015 Hyundai Sonata Hybrid Check Engine Light Reset

Resetting a check engine light on a 2015 Hyundai Sonata Hybrid may be simple or it may mask an underlying issue. Many drivers attempt a reset by disconnecting the battery or using a generic code reader, but a true resolution requires reading stored trouble codes, diagnosing root causes, and verifying repairs with Hyundai-specific tools. At Larry H. Miller Hyundai Peoria in Peoria, AZ, our technicians follow OEM procedures: we read and interpret codes, repair or replace faulty components with genuine Hyundai parts, and then verify repair with a follow-up scan. This prevents repeat light activations and unintended damage. We also document repairs to protect your warranty and resale value. Because some resets without repair can cause recurring failures or obscure hybrid-system warnings unique to the Sonata Hybrid, dealership service is the safer, more cost-effective route. We honor warranties, offer transparent estimates, and have flexible payment options including service financing.
