Your response is really appreciated.
Thanks to my extensive research and the identification of the vehicle's former owner, Kia has approved the vehicle's service history. Telling the garage workers to "shove it," he returned it to them. They agreed to take it, but he had to make a deal to purchase another vehicle from them.
However, in order for Kia to cover the costs of a new engine and inspection in the event of a manufacturing defect, the vehicle must still undergo an examination by a Kia garage, even if Kia has acknowledged the service history and said that the warranty is valid.
The oil, air filters, and vehicle were serviced three weeks prior to this. The car needed the right oil. A large amount of oil is still dispersed around my driveway! I am now in that position. The dealership isn't someone I trust to do the inspection, to be honest. Their allegiance will remain with Kia. However, I am completely stranded.
