Kia Troubleshooting Questions? Ask a Mechanic
Hello and welcome! My name is ***** ***** I can assist you with your question. You have a bad connection at or after the battery. Check for voltage on the fuses under the hood when this condition occurs. All fuses should have battery voltage. It might be a bad fuse block or connection at the fuse block as well.
The bad connection will surface once you put a load on the electrical components like when trying to start the engine. Make sense?
