Frequently Asked Questions

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

• Check for obvious issues first: ensure the charge plug is secure, the charging cable and port show no damage, and the 12V battery indicator (if present) is normal.
• Review recent events: did an abnormal charging session, low range, or unusual noise precede the light? Note these details for the technician.
• A soft reset (power cycle) can clear temporary faults, but persistent lights require diagnostics to avoid hidden damage.
• Remember: warranty-covered repairs must be performed at a certified dealership to preserve coverage and ensure proper parts and software updates.
