This time, as I was sitting in the car the seat belt light came on but I couldn't wait for the issue to resolve.

There has not been an incident yet but i don’t know who else to talk to. I am a FedEx Delivery driver and driver the largest Delivery truck made for FedEx and am fine with it ask day. However, the steering on my car is down right dangerous. My car drifts all over the road. It is ten times harder to keep my little cat on the road than my big work truck. So hard in fact that i have resorted to this. I am a good driver never even a ticket so i know how to drive. It’s not my driving please listen when i tell you something is WAY wrong with the steering or suspension or both on this vehicle. Just drive one and you will see very quickly what i am saying i promise!

Yes my son bought this car last year I have been checking since January there has still been no recalls on his particular car he was in a car accident and unfortunately him and his passengers were all killed. I have contacted an attorney who has sent an inspector they said initial look it look like something to do with a rod in the engine and it catching fire but from other things it’s possible he could’ve had other problems dealing with the brakes the emergency assistance. So they think possible electrical and what else they have not said. They are getting with Kia to get his car moved there so they can have one of their people take it apart to preserve evidence to find out which or if many of the recalls had happened to his more happened to his car

My Kia Rio 2020 had the check engine light come on today. The engine coolant temperature gauge went all the way to the Hot mark. The car is one year old and and has 60093 miles on it. The dealership Demontrond Kia refused to repair it under warranty. I called Kia corporate and was told the same thing. This is unacceptable. My expectation is that they will repair this issue for no cost. As all maintenance has been done at the dealership. I have not noticed any fluid leaks nor have I been told when at the dealership about any fluid loss.
