Hello, my sportage has been in the workshop for 4 months and find no fault. Errors are engine management, all assistant distance brake assistant airbag and battery with red symbol and the app and with red exclamation mark. When error erasure it goes again 2 days then he starts from now on no more. 6x was already ADAC since 2x of it would be dragged Fzg into the workshop. Now since 14.12.23 he stands permanently at the Kia dealer.fubden no error am for 3 weeks daily with Kia Germany in contact. Car is now towed to another workshop. My nerves are at the end. Perhaps one knows the problem I take any straw. From Kia Germany comes now a specialist, but that certainly takes until the comes for 4 months we pay a leasing rate and car used 300km, tomorrow the car becomes 4 months old. Hope it can help who.
