Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Kia EV3?

• Common causes include battery-management or high-voltage system alerts, inverter or traction motor sensors, coolant/thermal-management faults, and software or sensor communication errors.
• Because EV systems are high-voltage and software-driven, many apparent "engine" faults stem from electrical or control modules rather than fuel or exhaust components.
• Ignoring these warnings can reduce range, accelerate component wear, and increase repair costs over time.
• Nalley Kia often costs less than independent shops while delivering factory-trained technicians, genuine parts and warranty compliance that protect long-term value.

What does it mean when the check engine light comes on in a 2026 Kia EV3?

• It indicates the vehicle has detected a fault in the powertrain, battery management, charging system, thermal controls, or related sensors and control modules.
• Some alerts are minor software or sensor issues; others signal degraded performance or potential damage to high-voltage components.
• Our diagnostic tools identify the exact fault code so a targeted repair plan can be recommended quickly.
• Warranty-covered repairs must be performed at a certified dealership like Nalley Kia to preserve coverage and realize immediate and long-term savings.

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

• Confirm the vehicle’s charging status and any on-screen alerts; check the charging cable and connector for damage or poor contact.
• Look at the instrument cluster or infotainment messages for guidance—many EVs provide detailed fault notifications.
• Avoid DIY work on high-voltage components; instead contact Nalley Kia so factory-trained technicians can assess the issue safely.
• Bringing the vehicle to our service department quickly can prevent escalation, reduce repair cost, and protect warranty coverage.

How long does a check engine light service take?

• Diagnostics typically take 30–90 minutes depending on the fault and whether the issue requires road testing or system logs.
• Simple sensor resets or software updates can be completed same-day; complex high-voltage repairs or parts orders may take longer.
• Nalley Kia provides clear time estimates up front so you see immediate and long-term savings by avoiding incomplete fixes or repeated independent visits.
• If a warranty repair is needed, certified-dealership handling ensures proper repair procedures and faster resolution under warranty terms.
