“We understand the importance of protecting customer data and therefore work hard to create strong systems and processes. Additionally, these systems are regularly reviewed and updated as necessary. Once a customer has opted in to receive such updates, the repair order/invoice link will only be available on the customer’s registered page shared on mobile phone numbers. These are system-generated links without any human involvement. Hyundai assures that it will continue to work hard to safeguard the interests of its customers.”
