Frequently Asked Questions

What is the most common reason for check engine light on a 2022 Hyundai IONIQ 5?

• Often the light signals a battery management system (BMS) or charging-system fault — issues with the traction battery, charger port, or thermal management are frequent on electric vehicles.
• Sensors and control-module errors (inverter or motor control) can also trigger the indicator and reduce vehicle performance or charging ability.
• Ignoring these warnings can lead to reduced electric range, further component damage, and much higher repair costs over time.
• Many covered repairs must be performed at a certified dealership; we regularly deliver immediate and long-term savings versus independent shops while providing factory-trained technicians.

What does it mean when the check engine light comes on in a 2022 Hyundai IONIQ 5?

• It means the vehicle’s onboard diagnostics detected a fault in systems monitored by the ECU — for an EV this often involves the propulsion system, battery, charging components, or thermal controls.
• The light can indicate anything from a minor sensor issue to a serious drivetrain or battery problem; the dash will often show an associated message.
• If the car displays performance restrictions or warnings, avoid extended driving and have the system scanned immediately by our certified team.
• Repairs covered under warranty must be done at a certified dealership to preserve coverage and ensure proper parts and procedures.

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

• Safely pull over and check the instrument cluster for specific messages or warnings before continuing to drive.
• Verify the charging cable and port connection if you were charging or just finished charging; loose contacts can trigger faults.
• Try a full vehicle restart—powering the IONIQ 5 off and on can clear transient faults, but only after a confirmed scan should codes be reset.
• Schedule a diagnostic with our service team at Schedule Service so factory-trained technicians can identify and address the root cause.

How much does a check engine light diagnostic cost for a 2022 Hyundai IONIQ 5?

• Diagnostic fees at our dealership typically fall in a competitive range; while exact costs vary, you can expect a clear, upfront estimate after an initial scan (many diagnostics begin around a modest flat fee).
• If the repair is covered under warranty, required work must be completed at a certified dealership — that coverage can reduce or eliminate out-of-pocket expense.
• We often deliver immediate and long-term savings compared with independent shops because our factory-trained technicians use OEM tools, genuine parts, and accurate diagnostics that prevent repeat failures.
• Check current offers at Service Specials or contact our service advisors for exact pricing and appointment availability.

How long does a check engine light service take?

• Basic diagnostics are commonly completed within 30–90 minutes, depending on the issue and whether the vehicle needs to be brought into the shop for a full scan.
• Simple repairs or sensor replacements may be finished the same day; complex battery, inverter, or thermal-system repairs can take longer and may require parts ordering.
• If warranty repairs are needed, we coordinate parts and service to minimize downtime while ensuring OEM procedures are followed — that protects long-term value and coverage.
• To reserve a time and reduce wait, please Schedule Service online; our advisors provide accurate time estimates after the initial scan.
