NHTSA Complaint #11484326 — 2015 KIA OPTIMA

2015 Kia Optima Hybrid HEV system. Months after purchasing the vehicle two different lights would come on the engine. One is the HEV warning light and the other is a flashing “Turn off engine and check HEV system”. The first time it happened the vehicle turned off. It was towed to Kia, 02/2020. They change some sensor and sent me on my way. 3 weeks later the HEV warning light came on again so it was towed to Kia for the 2nd time, 03/2020. This time they said they could not recreate the issue. A month later the light came on again and again but since the light never stayed on, I kept getting told by Kia that I’d have to take it in when the light stayed on. 01/2021 the light came on again, with the flashing warning and the vehicle turned off, mid-drive. It was towed to a mechanic shop near me, where they replaced the wiring harness completely, but a month later the same light came on again. Over the course of the year, the warnings kept turning up and time and time I kept getting told they needed the light on at the dealer so they could determine with the codes, what is wrong. 07/2022, light came on as I was merging on to the freeway and the car shut off. I was able to make it turn on and make it home safe. The next day I towed it to the shop where they replaced the wiring harness and they stated they could not touch it further since the codes they got where “High voltage battery” codes and a specific tech is the only one when could work on it. I took it to Kia where it stayed 33 days. They changed a part. Two days later the HEV light came on again, so I took it back. They kept it one day, drove it 60 miles and they could not recreate the issue. I got it back on Saturday, 5 miles out the light came back again and again. I took video. Called Kia and now the car is back at the dealer while they try and figure out the issue. I’m scared for my life. The car gives no warning when it decides to shut off. Wheel locks on the times it does turn off. HEV system is no good.
