2022 Hyundai Sonata Check Engine Light Reset
Resetting the check engine light on a 2022 Hyundai Sonata without diagnosing the underlying fault risks recurring issues and warranty complications. While some owners may clear codes with a consumer scanner, only a certified dealership can confirm emissions-related faults, verify repairs with OEM tools, and preserve warranty coverage. At Herb Chambers Hyundai of Auburn we use manufacturer-grade scanners to capture freeze-frame data, confirm repairs with post-repair scans, and document service history. We provide transparent estimates, discuss OEM versus aftermarket parts, and outline immediate and long-term savings of proper repair—often costing less overall than repeat visits to independent shops. If the issue is minor, we’ll explain repair options and costs; if it’s covered under warranty, repairs must be completed at a certified dealership to remain valid. For convenience, financing is available and you can schedule appointment online or review current service specials.
