| Gas Recirculation Valve (egr Valve) problems |
For the 2nd year, my kia would not start in 32 degree weather in big bear, CA. This is an annual trip & took my kia. The lights, radio all turn on but the engine will not start. I have to wait until noon for the sun to warm up the car & then it's back to normal. I have taken the car back to the dealership & have been told they cannot find any malfunction & never heard of anyone experience what I have. There are many forums with kia owners complaining of the same, but cannot get a fix or acknowledgement that the problem exists. It's beyond frustrating when the car has less than 40k miles.
