Bought a 2021 Telluride with 22,000 miles. Last week hit 23,000 miles I dont know if it is a coincidence but last Thursday I began smelling hot coolant. It is at Kia now. They say they can smell it but can't find the source. Now I'm finding several post about the issue with even a Kia Service Advisor saying they are seeing this issue often and need help identifying it. Has anyone else had this issue?
