I have a 2019 Kia Soul I bought new. I have 40,000 miles on it. This happen on a Sunday I had been out and got home and layer around 5 pm. The Kia wouldn't start. I tried several times all.the ignition would do is click click click. After several times I hooked up my battery charger. After 5 to 10 minutes I tried it again. It started right up. I unhook charger. I let it idle for 30 minutes no problems. I tool it out and came back. I turn it off. It started right back up. Several times I did it and it started every time. Today I stop at a post office no more then 10 minutes the Kia wouldn't start. Again I get click click click trying to start it. With luck a receptacle was close by I plug in my charger and hooked it up. After 5 minutes it started right up. I went and had the battery and alternator check. Both good. Guy says my alternator is charging the battery and it's fully charged. So my question what is going on withy Kia? I have and appointment with Kia garage on September 30 to bring it in . Can anybody give me any ideas? I have started it several times this evening and no problem. I was told battery and alternator is not the problem. Why does hooking my charger to battery let's me Start it in a few minutes. If battery checks good. Auto Zone check battery.
