Electrical system
2020 Kia Niro was driving fine until one day while driving down the highway at highway speeds (65-70 mph), the car began to lose power and as we switched lanes to get to the side of the highway, the car began to smoke and caught on fire. Our safety was at risk due to the car catching on fire. The problem is unable to be reproduced as the car is a total loss. Vehicle was inspected by police at the scene. There were no warning lights, and the vehicle had been in working condition prior to the incident. The vehicle had a recall that was fixed at our local Kia dealership as soon as a solution was indicated, and the part was located.
One night the tailgate latch began clicking, locking and unlocking itself and then not latching closed, causing the inside light to remain on and the tailgate open indicator to display on the display panel. Then it just went dead and would not open at all, even if using the specific tailgate open key on the key fob. Then a few weeks later while driving on an empty street very slowly as I was turning a corner, with no warning the back windshield suddenly made a loud noise and then spontaneously shattered. I got out and looked around and there was no one else around or any other cars driving by. I did not hear any impact and also had my driver window down and did not hear any shots, and was not able to recover anything from the inside the back of the vehicle or on the ground that could have hit it. …
