2021 Kia Stinger Electrical System Problems

After failed first fix at 300 miles, wife was driving an ran out of gas on highway around 800 miles on O/D. Told this time the entire instrument/gauge cluster is bad. Dangerous situation to run out of fuel on a highway. Kia roadside assistance driver would not come and get her as she was on an Express Lane. Had to fill up car with fuel myself (after scrambling down highway embankment) while standing in traffic lane (fuel fill cap is on driver's side).

BRAND NEW CAR, JUST OVER 300 MILES ON THE ODOMETER. SUDDENLY LOST POWER WHILE DRIVING ON A BUSY MAIN ROAD IN FAIRFAX, VA. WAS ALMOST REAR ENDED (INCHES TO SPARE) AND STRANDED ON THE ROAD. CAR WOULD NOT RESTART. A POLICE OFFICER RESCUED ME AND PUSHED ME TO SAFETY ON A NEARBY RESIDENTIAL SIDE STREET TO AWAIT A TOW TRUCK. TURNS OUT THERE WAS A DEFECT IN THE WIRING FROM THE FUEL SENDING UNIT AND THE FUEL GAUGE WAS REPORTING JUST UNDER HALF A TANK DESPITE BEING EMPTY. THE VEHICLE WAS SO NEW THAT I HAD NOT FILLED IT UP SINCE TAKING DELIVERY. GIVEN THIS WAS A BRAND NEW CAR, SPORADIC DRIVING DUE TO THE PANDEMIC, SHARING THE CAR WITH MY WIFE AND THE FACT THIS CAR IS MUCH LESS FUEL EFFICIENT THAN MY PREVIOUS CAR, I DID NOT REALIZE THE GAUGE WAS STUCK AND WAS NOT AS SUSPICIOUS ABOUT IT AS I WOULD PERHAPS HAVE BEEN IN ANOTHER CAR. MOMENTS EARLIER, I HAD BEEN ON A BUSY HIGHWAY WITH NO SHOULDER DUE TO CONSTRUCTION. IF I HAD RUN OUT OF GAS THEN, IT COULD HAVE BEEN A VERY DANGEROUS SITUATION. UNEXPECTEDLY LOSING ALL POWER AND NOT KNOWING THE FUEL LEVEL IN THE VEHICLE COULD LEAD TO A VERY DANGEROUS SITUATION. I WAS FORTUNATE THAT I DIDN'T GET REAR ENDED, AND THAT THERE WAS A POLICE OFFICER NEARBY WHO CAME ACROSS ME AND HELPED.
