A computer network outage that began last Saturday affected the services of Kia and Hyundai Motor America. The issue affected dealers’ ability to order vehicles, parts and had knocked offline an app used to start and warm-up vehicles. The automaker said that there was no evidence of them being a victim of ransomware and it was mere online speculation. Hyundai insisted that only a limited system were affected but neither of them provided an explanation for what caused them.
