“I have a ‘21 Sorento hybrid. The refill inverter coolant warning light keeps coming on. The first time it happened was on a road trip. A local dealer told me to check coolant levels and when it was full, told me it was safe to drive. I had it looked at as soon as I got home. By that time, the light had gone off. They flushed and refill the coolant. It happened again within 3 weeks. I took it in again. The dealer inspected said nothing was wrong with vehicle. Safe to drive. Also said I was the second one of these they’d seen. They were told corporate is working on a fix. …”
NHTSA complaint #11462799, filed 2022-04“We had just received our Sorento back from being in the shop for 4 months due to being in an accident. Part of the repair work was to have the software updated and reprogrammed at a Kia dealership, which was completed. We picked up the car on Tuesday, Feb 15, 2022, and on Wednesday, Feb. 16, as we were traveling down hwy 27 in Lake Wales, FL, the alert began to ding and the hybrid warning came on, as well as other lights (I can't remember which ones). The car lost acceleration capability, but as we slowed and turned down another road, the car began to slightly accelerate very slowly. …”
