Frequently Asked Questions

How much does a check engine light diagnostic cost for a 2020 Hyundai Kona Electric?

• Typical diagnostic fees at certified dealerships range from about $80–$200 depending on the time required to trace high-voltage and control-system issues.
• Nalley Hyundai often costs less than independent shops while providing factory-trained technicians, OEM tools, and accurate root-cause diagnosis that prevents repeat repairs.
• Immediate savings come from accurate diagnosis; long-term savings come from avoiding unnecessary parts replacement and preserving warranty coverage.
• If a repair is covered under warranty, it must be performed at a certified dealership to maintain coverage—our team will advise you clearly before work begins.

What does it mean when the check engine light comes on in a 2020 Hyundai Kona Electric?

• The light can signal a range of issues from minor sensor faults to high-voltage system alerts related to the battery, inverter, charger or thermal management.
• On an EV like the Kona Electric, some codes indicate charger or battery temperature events rather than traditional emissions faults; trained technicians interpret these signals correctly.
• Early diagnosis reduces the chance of escalation to costly repairs—dealer diagnostics identify the true cause and recommend the correct OEM repair.
• Warranty-covered repairs must be completed at a certified dealership like Nalley Hyundai to ensure coverage and correct software calibration.

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

• Safely check charging status and 12V battery condition—many EV warnings originate from accessory power or charging faults rather than propulsion systems.
• If the light is flashing, pull over and power down; flashing often signals an urgent fault requiring immediate attention.
• Review the owner’s manual for simple prompts and then schedule a diagnostic with Nalley Hyundai to avoid misdiagnosis or cosmetic resets that mask underlying problems.
• Remember: authorized service preserves warranty eligibility and can deliver both immediate and long-term cost savings versus piecemeal repair attempts.

How long does a check engine light service take?

• Basic diagnostics are often completed within 1–2 hours; many issues can be identified same day depending on technician availability and part needs.
• Simple fixes—sensor replacement or software updates—may be same-day jobs; complex high-voltage or battery repairs can take longer to ensure safety and correct calibration.
• Nalley Hyundai prioritizes accurate repair over speed alone: factory-trained techs complete proper testing and software reprogramming so faults do not return.
• When repairs are covered by warranty, work must be done at a certified dealership; we’ll explain timing and any loaner or shuttle options up front.

What is the most common reason for check engine light on a 2020 Hyundai Kona Electric?

• Common causes include sensors (temperature or voltage), charging-system faults, 12V accessory battery issues, or software alerts from the inverter/charger.
• Because EV systems are interdependent, a simple sensor fault can trigger the check engine light while masking the larger issue—proper diagnostic tools are required.
• Nalley Hyundai’s technicians use OEM scanners to determine the exact fault, which reduces unnecessary parts replacement and lowers your total ownership cost.
• If the repair falls under warranty, certified-dealer service is required to keep coverage in force and protect long-term savings.
