2022 Kia Seltos Power Train

I own a 2022 Kia Seltos that has experienced a persistent coolant leak. I’ve brought the vehicle in multiple times, but each time I was told the issue couldn’t be duplicated. The coolant reservoir was consistently dropping week after week. Dealership had even marked the reservoir with a line for tracking purposes. Despite keeping the vehicle for several days, the technicians were still unable to locate the source of the leak. I was then informed that any further diagnostic work would incur a service charge. When I expressed concern about this, Mark responded by saying, “The mechanics do not work for free.” Before I picked up the car, Dealership called to let me know a technician had accidentally broken a part, which they replaced. He stated the broken part was unrelated and that the original issue still had not been identified. I retrieved the vehicle and, interestingly enough, for over a year afterward, the coolant level remained stable. After this I contacted KIA corporation and I was advised they could not help in the matter and I'm have to work with the dealership. While changing the oil on [XXX]—roughly three months since I last checked the reservoir—I noticed the coolant level had dropped again, below the “low” mark. I refilled it to avoid potential damage, but it appears the original issue has returned. Ive notified the dealership on 6/19/2025 the issues has returned, I haven't heard back from as of today. The vehicle is still under it's 100K mile warranty and I need help getting KIA to honor it's warranty and not force me to pay for diagnoses. I'm being told this should fall under the lemon law and get a lawyer. I'd rather not go this route , as it's still forcing me to spend money.
