So far the only problem we've had with our 2017 Niro EX (purchased in July) was a door handle breaking off, part of the door handle recall. All fixed all is good. Until this evening. I have not read about this problem anywhere as of yet. Tonight after dinner I was going to make a quick run to the store. The Niro had been running fine all day. This trip, when I get in and start the Niro, I have - - - flashing instead of the miles remaining display, the gas pump icon is lit up, and the gas gauge has NO little boxes, not even one, indicating it's EMPTY. There's also a lighted icon displaying a vehicle parked in front of a gas pump, AND the engine light is ON. This thing wants gas!! Well, I gassed up to a full tank on Saturday, 3 days ago, and only put on 25 miles, so it's NOT empty!! The engine WAS running. When it turned off and went into full electric (EV) mode, I forced the engine back on by turning the heat to HIGH, engine came right back on, sounded fine. It was about 30 degrees out. I thought perhaps it was a ill fitted gas cap, or perhaps worse yet a gas theft,,,,,,,pressed the gas door open button, got out and checked, removed the gas cap just in case and re-seated snugly, ONE click, got back in, turned the car OFF, waited a min., turned car back ON, and same problem. Obviously NO signs of forced entry into the gas door so I'm assuming I'm near FULL on gas. Hybrid battery power was good. I decided to proceed on my short trip to the store. Everything ran fine, seemed to stay in EV a bit more than usual as it was 30 degrees out and I lowered the heat to 72, defrost is on, heated seat is on, rear defrost/heated mirrors are on............everything drives normally.......... I again switch the heat to max thinking it's in EV mode a bit more than usual for a COLD start up and heat set at 72,,,,,engine comes right back on, this thing was running quite normally, smooth, no other obvious problems........ my MPG stayed about where it last was prior to this problem and shutting the car OFF earlier in the day...................after my in/out at the store I decide to top off the gas, it only got up to $2.08, so I was down less than a gallon, but my thinking here was that it might trip the gas sensor back to normal..............I had decided, and still feel, that this must be a gas sensor issue,,,,,,,,,,,, OR possibly a software issue,,,,,,,,,maybe needing a "reset"............Also I have my Niro EX set to RESET the MPG on each refill, so my topping off the gas should have reset the MPG display, it did NOT, it always has reset in the past. I do not believe it's current state is so critical that it' can't be driven short distances..............I plan to drive to work tomorrow, VERY short trip, call the dealer as soon as they open, and hopefully get an appointment for tomorrow sometime, and leave right from my office straight to the dealer (only 2 miles). I have approx. 3,400 miles on the car, purchased in July, yes, LOW use LOW mileage. I'm still a fan of this car but after reading about the severe "jerkiness" some have experienced at 6,000 miles and some had full vehicle replacements, I'm wondering what other oddities are going to pop up with this vehicle. I know it's a 1st generation, and there are bugs,,,,,,,,,,, but..............hoping for the best,,,,,,,,,,the true test is how quickly the problem is resolved. Our local dealer was GREAT about our broken door handle. It happened in early fall, heavy rain was forecast, and knowing lots of water would have gotten inside the door, our dealer took a door handle off an unsold LOT Niro, NEW, same color, and left it installed on our Niro until the recalled replacement door handles came in, can't ask for better service than that!! I will update as this progresses.
