NHTSA Complaint #11709255 — 2017 KIA CADENZA

This vehicle was inherited to me in 2019 from my father who puchased it cash on 10/13/2017. On 4/19/2018 he brought it in for a check engine light which was related to recall sa299 (ELECTRONIC THERMOSTAT). On 7/11/2018 service was performed again. On 3/4/2022 I brought in for check engine light with same recall for ELECTRONIC THERMOSTAT. On 11/10/2025 car showed engine overheating. In fear, I immediately brought to closest mechanic stating same problem, ELECTRONIC THERMOSTAT AND RADIATOR HOSE WHICH GOES HAND IN HAND. Before work began I left voice mails and emails with the service manager of Rohrman Kia in Schaumburg, Il. No one reached out. I spoke with Jim at same location on 11/10/2025 at 4:00 pm who told me it was my responsibility because the part was no longer under warranty. I filed a complaint (24149522) with BBB. on 11/13/2025 after I had to pay my mechanic $1000 to fix problem which obviously is a defect. On 12/3/2025 I spoke with Mike from Kia who said part was no longer under warranty and will not reimburse. I asked him to prove the previous thermostat was installed correctly according to the service action sa 346 and he said they have certified techs and they do not have to prove that to me. I would like Kia to accept responsibility for this part. Also carfax does not show all times Kia replaced that thermostat.
