2018 Kia Cadenza 4 DR FWD

I PURCHASED A NEW 2018 KIA CADENZA WITH 11 MILES ON IT. I HAVE HAD THE CAR LESS THAN A YEAR AND IT RANDOMLY STALLS WHILE IN DRIVE MODE IN MOTION AND SOMETIMES WHILE SITTING IDLE. IT HAS STALLED ON THE FREEWAY, NEIGHBORHOOD STREETS, DRIVE-WAY AND ON FEEDER ROADS. THE CAR HAS BEEN IN AND OUT OF THE DEALERSHIP AT LEAST 5 TIMES. KIA MOTORS CANNOT FIGURE OUT WHAT'S WRONG WITH THE VEHICLE. THEY PLACED A TRACKER IN THE VEHICLE AND DETERMINED THE CRANK SENSOR WAS MALFUNCTIONING. THEY REPLACED THE CRANK SENSOR, I PICKED THE VEHICLE UP AND LESS THAN 24 HOURS LATER THE CAR STALLED AGAIN. IT STALLED 2 ADDITIONAL TIMES BEFORE RETURNING IT TO THE SHOP AGAIN THIS PAST WEEK.

WE BECAME MORE CONCERNED AFTER SEEING A REPORT ABOUT FIRES INVOLVING KIAS THIS MORNING. OUR NEW 2018 KIA CADENZA HAD ABOUT 1,750 MILES ON THE ODOMETER ON OCTOBER 11, 2018, WHEN THE FOLLOWING OCCURRED: WE WERE ON A CITY STREET, STOPPED AT A STOP LIGHT, WHEN WE SAW SOME SMALL, LIGHT STRANDS OF SMOKE THAT SEEMED TO BE RISING JUST OUTSIDE THE RIGHT, FRONT FENDER. WE PULLED INTO A NEARBY PARKING LOT & CHECKED UNDER THE HOOD. THERE WAS A SMELL. IT SEEMED LIKE SOMETHING HOT OR SCORCHED (RUBBER OR OIL RELATED??), BUT NO SMOKE OR LEAKS WERE NOTICEABLE. IT DID SEEM LIKE THERE WERE SMALL SPOTS, SCATTERED ON THE UPPER SURFACES TO THE RIGHT OF THE ENGINE. AFTER PARKING IN OUR GARAGE AT HOME, THE SMELL BECAME VERY STRONG & REMAINED THAT WAY IN THE CLOSED GARAGE. WE DID NOT CHECK TO SEE HOW LONG THE SMELL REMAINED STRONG, BUT IT WAS STILL VERY NOTICEABLE WHEN I RETURNED 10 OR 15 MINUTES LATER. YESTERDAY, ON 10/12/18, WE BROUGHT THE VEHICLE TO THE KIA GARAGE & REPORTED THIS. THE SERVICE ADVISER LOOKED UNDERNEATH, SAID THAT SOMETHING WAS GOING ON AND SENT IT TO THE SHOP TO CHECK. AROUND 90 MINUTES LATER, HE SAID THEY FOUND WIDESPREAD SPLASHES OF OIL, BUT HAD CLEANED THE ENGINE. HE ASKED IF WE HAD DRIVEN OVER ANYTHING LIKE THAT, BUT WE HAD NOT. THEY HAD RUN THE ENGINE & TEST DRIVEN FOR AT LEAST 40 MINUTES - BUT HAD NOT BEEN ABLE TO DETECT LEAKS OR OTHER SOURCES OF THE PROBLEM. THEY ALSO NOTED THAT THE OIL LEVEL WAS STILL FULL. HE SAID TO TAKE THE CAR, DRIVE IT FOR 100 MILES, THEN BRING IT BACK FOR FURTHER TESTING. THE SMELL IN THE GARAGE WAS STILL NOTICEABLE AFTER RETURNING HOME, BUT NOT NEARLY AS STRONG AS THE PREVIOUS DAY. WE ASSUME THIS IS BECAUSE THE GARAGE HAD CLEANED THE ENGINE. WE DO PLAN TO TAKE THE CAR BACK AFTER 100 MILES, BUT WE ARE QUITE NERVOUS DRIVING IT ANYWHERE NOW.
