Driving down the interstate at 70mph and the vehicle suddenly began to brake and the forward collision warning light illuminated along with the check engine light. The car stopped on the interstate and this happened at 1:15 am and it was in a rural area and it was pitch black outside. Luckily no one plowed into the back of the car. Was able to restart the car and was barely able to get it to the side of the road before it shut down again. 6 miles to the nearest exit attempted to get the car off the highway. After several attempts and turning off every electric accessory and sensor was able to get the car to the exit. KIA toed the car to the nearest dealership the next day. They discovered that the wiring harness was chewed up in several places and caused numerous shorts circuits and malfunction codes. I own several vehicles that are parked in the same area and this is the only one that has chewed up the wiring. My daughter and 2 of the grandchildren were in the car when this happened and they could have been killed if someone had plowed into the back of them at 70+ mph. This is a 2020 Kia Sedona and I'm being told that this is not covered under warranty. There is something wrong here seeing how this only happened to this car and not my other cars nor my boat. The car is in the shop and will not be ready for a week or two and this happened more than 350 miles from my house. I have lost the use of this car and Kia refused a rental because they said it was not a warranty issue. I know Kia is having this same issue with many of their vehicles. Does it take people to die for this to be addressed? I hope not. My family could have easily been killed because of this. Luck is probably the only thing that prevented a tragedy here. The car has not been repaired yet so I don't have any documents to upload yet.
