Bought my new Niro last week. Now have 210 miles on odometer. This evening, I was driving home from a church three miles away when the dash lights went dim. Car kept running so I didn't stop. Soon the lights faded out completely and the headlights went off. Fortunately, it was just at dusk so I could see and be seen. I turned off the headlights and, as I came down a hill nearly a quarter of a mile long, the lights on the dash became brighter. I could see the lights that indicate charge in the battery were showing almost a half charge. When I ran out of down grade, the dash lights again dimmed to nothing. First thing in the morning I'll call the dealer. I'm hoping he won't say drive it in as the nearest dealer is at least 25 miles away and I wonder if I'll get there. I'm not going to tinker but I'm wondering if any of you experts have thoughts about what is going on here?
