Frequently Asked Questions

What is the most common reason for check engine light on a 2026 Hyundai Palisade?

• Most frequently the light is triggered by emissions and fuel-system issues such as a loose gas cap, faulty oxygen sensor, or an EVAP leak.
• Less common but important causes include engine misfires or failing catalytic converters, which should be addressed quickly to avoid costly damage.
• Nalley Hyundai’s factory-trained technicians use OEM-grade diagnostics to pinpoint the exact cause and recommend the most cost-effective repair.
• Having repairs performed at our certified dealership protects warranty coverage and often costs less than independent shops, delivering immediate savings and long-term value.

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

• The check engine light indicates the vehicle’s onboard diagnostics detected an issue with emissions, engine performance, or drivetrain systems.
• It can range from minor (loose fuel cap) to serious (engine misfire or catalytic converter problems), so a proper scan is the only way to know.
• At Nalley Hyundai we perform full OBD-II diagnostics with factory-level tools to identify codes, recommend repairs, and estimate costs clearly.
• Warranty-covered repairs must be completed at a certified dealership to preserve benefits and often yield immediate and long-term savings compared with independent alternatives.

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

• Start with simple checks: ensure the fuel cap is tightened securely—an unchecked cap commonly triggers an emissions code.
• If the light stays on, avoid guessing: bring the Palisade to Nalley Hyundai for an accurate scan rather than performing resets at home.
• Our service team will read codes, explain the findings, and recommend repairs or maintenance, using OEM parts and factory procedures.
• Having the work done at our certified dealership preserves warranty coverage and typically results in lower total cost of ownership compared to unverified repairs.
