My 2020 Kia Rio S caught fire spontaneously while parked and unattended for 5 hours at my work parking lot. The vehicle was turned off and had not been involved in a collision. I was notified of the fire after it had already started. The fire caused catastrophic damage to the passenger compartment and resulted in a total loss of the vehicle. Component/system suspected: The exact component that initiated the fire has not yet been determined. Based on the circumstances, I am concerned about a possible vehicle electrical or mechanical failure, but I do not want to speculate as to the cause without investigation reports. The vehicle was subsequently taken to a salvage/inspection facility. I am currently determining whether it remains available for inspection. Safety risk: The vehicle caught fire while parked without an apparent external cause. The fire became extensive enough to destroy the passenger compartment and vehicle. This created a significant fire hazard to nearby vehicles, property, and people. Had the vehicle been parked in a garage or other enclosed area, or had someone been inside or near the vehicle when the fire began, the potential consequences could have been severe. Reproduction/confirmation: The problem has not been reproduced by a Kia dealer or independent repair facility. The vehicle was destroyed by the fire and declared a total loss. Inspections: Boise Fire Department responded to the vehicle fire. Progressive Insurance subsequently inspected/handled the vehicle and classified the loss as a non-collision total burn/total loss. I have requested the complete Boise Fire Department records and additional records from Progressive concerning any investigation into the origin and cause of the fire. Kia has not yet inspected the vehicle to my knowledge. Warnings/symptoms before the fire: There were no warning lights, messages, smoke, unusual odors, electrical problems, noises or any other symptoms I was aware of. No after market electronics or anything.

I went into a rural King store to shop when I came back out my car was completely filled with smoke. I opened the front passengerdoor and the smoke hit me in the face it was so thick and green it was just it took my breath. It took me 10 minutes to locate what had happened and down on the door frame of the passenger side of the front seat where the wiring is there was a whole melted all the way through that panel and you could see the wiring was exposed so I assume that the wiring had caught on fire. I'm not sure about this it has been looked at and it is at Jeff Wilder Toyota in Clarksville Indiana. They want me to pay $1,000 deductible for this but I feel like if it was a wiring issue key is should be responsible. I am going through a flood right now in my home and now I have to deal with that and I don't think I'm even responsible for the payment I think he is at the cover it.

I came out of a store last week and there was smoke inside my car and when I opened the door there was a hole down by the door frame on the passenger side that it burned all the way through to the frame of the car and now my lights are flashing on and off and sometimes a passenger headlight works sometimes the driver had light works but it's either one or the other it's doing all kinds of crazy stuff with the lights now I'm thinking it has to be in the electrical fire because it got hot enough to melt all the way through the plastic part of the bottom of my door I do have pictures

I believe my Kia Rio S falls victim to the recall 2020 Kia Rio models have faced. Brake performance has been severely degraded on my vehicle over the past few weeks despite doing all recommended maintenance. When I first got my 2020 Kia Rio S I could brake with 5% pressure applied to the brakes, now it takes about 25-30% pressure and it seemingly is increasing every day. I have contacted the manufacturer and they advised me it would be a $2000 service charge minimum.
