Check Engine Light Flashing
The check engine light flashing on a 2024 Hyundai Sonata usually signals an active misfire or another critical condition that can damage the catalytic converter if continued. A flashing light means the engine control module is detecting unburned fuel entering the exhaust, which raises temperatures and risks a costly converter failure. At Herb Chambers Hyundai of Auburn we prioritize immediate assessment because addressing a flashing condition quickly prevents cascading damage and larger bills down the road. Our certified technicians have factory-level tools to capture live data, identify whether ignition coils, spark plugs, fuel injectors, or sensors are at fault, and then recommend the most cost-effective repair strategy. We use OEM parts to ensure the fix restores original performance and emissions compliance, and we explain the expected savings of prompt repair compared with deferred fixes. If financing would help, we offer service financing so you can get the repair done now and pay over time. Check our current service specials and schedule service online to get priority assistance and protect your Sonata.
2024 Hyundai Sonata Check Engine Light Reset
Resetting the check engine light on a 2024 Hyundai Sonata can be a quick step, but it is not a substitute for diagnosis. Clearing codes without fixing the underlying issue will often cause the light to return and can mask intermittent faults that harm fuel economy and long-term reliability. At Herb Chambers Hyundai of Auburn we will explain whether a reset is appropriate after a confirmed repair, and we record repairs to maintain transparency and proper warranty documentation. We insist on OEM procedures and parts so that your vehicle retains manufacturer-level performance and coverage; remember that any warranty-covered repairs must be performed at a certified dealership. Our shop offers clear, itemized estimates and the immediate advantages of factory training — which often means lower total ownership cost compared with repeated independent repairs. Take advantage of our service financing and current service specials to make the right repair now. To protect your Sonata and avoid repeat trips, schedule service with our technicians who will both diagnose and, if appropriate, reset the light properly after completing repairs.
2024 Hyundai Sonata Check Engine Light Codes
Common codes on a 2024 Hyundai Sonata include P0420 (catalytic converter efficiency), P0300 (random misfire), P0171/P0174 (system too lean), P0135 (O2 sensor heater), and P0442 (EVAP small leak). Ignoring each has a cost: a P0420 left untreated can lead to expensive catalytic converter failure, P0300 can cause drivability loss and damage to the exhaust, and lean codes like P0171 reduce fuel economy and may cause engine wear. Herb Chambers Hyundai of Auburn in Auburn, MA, diagnoses these codes with OEM scanners that read freeze-frame data and long-term trims so we can recommend targeted repairs that protect your fuel economy and vehicle life. Our certified technicians prioritize solutions that maximize immediate savings and long-term value — using genuine Hyundai parts and published procedures to avoid recurring failures. We provide transparent estimates, show you the code details, and explain the consequences of delaying repair so you can make an informed decision.
