Frequently Asked Questions

What is the first thing to check when the check engine light comes on?

Check the gas cap for looseness or damage — a common, low-cost cause that can trigger a code.
Verify basic fluids and oil level; low oil or contamination can prompt a warning.
Look for obvious issues like a disconnected vacuum hose or a battery problem affecting sensors.

What does it mean when the check engine light comes on in a 2026 Hyundai Kona?

It signals the vehicle’s engine management system has detected a fault — from an emissions issue to a misfire or sensor failure.
Codes are stored in the vehicle computer and reveal whether the issue is minor (e.g., evaporative leak) or urgent (e.g., misfire).
Some faults affect fuel economy or emissions; others can risk catalytic converter damage if left unaddressed.
Prompt dealer diagnosis helps protect performance, lower fuel costs and avoid costly downstream repairs.
Remember: warranty-covered repairs must be performed at a certified dealership to maintain benefits and ensure long-term savings.

How long does a check engine light service take?

Basic diagnostics commonly take 30–90 minutes to read codes, test drive and inspect systems.

For warranty repairs, completing service at a certified dealership ensures proper documentation and long-term protection.

2026 Hyundai Kona Check Engine Light Flashing

A flashing check engine light usually indicates a severe misfire that can rapidly overheat and damage the catalytic converter. Continued driving in this state risks costly converter replacement and can increase emissions dramatically. If you see a flashing light, reduce speed and avoid heavy acceleration; have the vehicle towed if recommended. At Courtesy Hyundai of Tampa we treat flashing warnings as urgent. Our technicians will inspect ignition components, fuel delivery and sensors, and recommend immediate repairs to prevent secondary failures. Addressing a flashing condition promptly at a certified dealership protects warranty coverage, preserves long-term performance and often costs less than delayed repairs after more extensive damage has occurred.

2026 Hyundai Kona Check Engine Light Reset

Resetting the check engine light without diagnosing the cause can hide underlying problems and lead to bigger expenses later. Dealers can clear codes after a full diagnosis and repair, ensuring the issue is truly resolved. At Courtesy Hyundai of Tampa we use factory tools to read freeze-frame data and confirm repairs; if the fault returns we re-check at no extra charge under many service agreements. Performing repairs and resets at a certified dealership preserves warranty coverage—any warranty repairs must be done by a certified dealer—and provides long-term savings by preventing repeat failures and incorrect part replacements often seen elsewhere.

2026 Hyundai Kona Check Engine Light Codes

Common codes for this model include P0455 (evap leak), P0420 (catalyst efficiency), P0300 (random misfire), P0171 (system too lean) and P0135 (O2 sensor heater). Ignoring these can raise fuel consumption, harm emissions systems and lead to expensive catalytic converter or engine repairs. Repair costs vary: a loose gas cap or evap repair is low cost, O2 sensor replacement typically runs a few hundred dollars, while catalytic converter work can exceed a thousand. Courtesy Hyundai of Tampa provides accurate code interpretation, upfront estimates and OEM repairs that often save you money immediately and across the vehicle lifecycle.
