Check Engine Light Flashing

The sight of a flashing check engine light on a 2022 Hyundai Sonata Hybrid is an urgent signal that the engine control module is detecting a misfire or another condition that could quickly damage the catalytic converter or other drivetrain components. A flashing light usually means you should stop driving when safe and have the vehicle inspected immediately. At Herb Chambers Hyundai of Auburn in Auburn, MA, our service drive is equipped to prioritize flashing codes so you receive prompt attention. Our certified Hyundai technicians perform a targeted diagnostic, using OEM scanners and manufacturer procedures to identify misfires, ignition faults, or fuel system irregularities.

2022 Hyundai Sonata Hybrid Check Engine Light Codes

Understanding the most common check engine light codes for a 2022 Hyundai Sonata Hybrid helps owners make informed decisions and avoid cascading failures. Typical codes include P0420 (catalyst system efficiency), P0300/P0301 (random or cylinder misfire), and P0171/P0174 (fuel trim lean conditions). Left unaddressed, a P0420 can lead to reduced fuel economy and potential catalytic converter replacement — a costly component — while persistent misfires (P030x) can damage pistons or the catalytic converter. Lean conditions (P017x) often signal vacuum leaks or fuel delivery issues that affect drivability and efficiency. At Herb Chambers Hyundai of Auburn, our certified technicians diagnose these codes with OEM tools, provide clear price estimates, and explain how timely repairs reduce long-term ownership costs. We emphasize convenience — quick check-in, accurate diagnostics, and access to genuine parts — and we often offer service pricing that compares favorably to independent shops when warranty, parts quality, and long-term reliability are considered.
