For the second time in the past month the car would not start. Appears to be due to a dead battery however the dealership has been unable to locate a problem. Looking online and it appears to be a issue that Kia is aware of but not owning up to.

I’m not really sure what the problem was. I feel like the car may have lost power and I lost function of the car / brakes. I’m assuming it’s either an engine or electrical.

My 2021 Kia Seltos shut off while I was driving it. This happened once in July 2021, I was at a stop sign and I attributed it to not driving it in a while and the extreme summer heat. But on January 31st, I had turned my car on, I let it “warm up” and then I started to drive.

Two issues with my vehicle: 1. When driving and stopped at a red light, the stop/start technology will engage, turning off my engine. Upon the light turning green again, my foot comes off the brake to hit the acceleration but the entire dashboard/electrical system restarts like the car has just been turned on.

The entire electrical system (display, gauges, exterior lights, etc.) resets while driving. This may be a one off or may happen several times in a few minutes. The engine never stops running, which is good as this happened in the interstate.
