NHTSA Complaint #11703872 — 2015 KIA OPTIMA

In September of 2025, my radio and back up camera stopped working. I contacted Hayward Kia and was informed by staff member, Eraca Craig, that my 2015 Kia Optima needed a software update that was covered by a recall. I waited several weeks for the dealership to contact me once the update was available. During the waiting period my car's battery started to drain intermittently. I had to have the battery recharged multiple times by AAA. The battery would stay charged for a few days, maybe a week, then I'd experience the same issue. AAA towed my car to Kia Hayward on October 3, 2025. They charged my battery and kept my car over night to see if the battery would stay charged, it did not. Eraca told me that the AC Delco battery I purchased on January 16, 2025 was not "compatible" with my car. She recommended a factory Kia battery which I purchased on October 7, 2025. By November 1, my Kia battery had drained. AAA recharged the battery and it held a charge until November 25, 2025. When I took my car to Kia on November 11, 2025 for the software update, I was told that the update did not apply to my malfunctioning radio and camera therefore I needed to replace the entire unit for $4,080.49. On December 6, 2025 I had a diagnosis performed on my car, it reported codes C1102, B1102, B1112, and P000. C1102 indicates an issue with the HECU. My 2015 Kia Optima has had three recalls related to the HECU (#SC284,#SC212, &#SC197). On December 8, 2025 I made a request, via e-mail, to Eraca Craig that my HECU be inspected for leaks and to have the HECU fuse replaced. I understand that these services were recorded as performed in the past, but I need them performed again because I'm not satisfied that Kia has remedied the situation. I've also filed complaints with the Kia Customer Care Center. My case numbers are #25697367 and #25723089.
