NHTSA Complaint #10992887 — 2016 FIAT 500X

I WAS MAKING A SLOW TURN IN A PARKING LOT AND THE CAR TURNED ITSELF OFF WHILE DRIVING. THE RADIO REMAINED ON AND DASH LIGHTS/GEAR LIGHTS WERE ILLUMINATED BUT THE CAR WAS COMPLETELY UNRESPONSIVE OTHERWISE. I REALIZED IT HAD TURNED OFF SO I RESTARTED IT & IT CONTINUED TO DRIVE NORMALLY. ABOUT 50 MILES LATER I WAS DRIVING 35MPH AND A WARNING LIGHT CAME ON STATING "DRIVE MODE UNAVAILABLE" THEN ANOTHER SAYING "SERVICE ENGINE". I TOOK IT TO THE DEALERSHIP WHERE THEY SAID IT JUST NEEDED SOME UPDATES, GAVE IT THE UPDATES, AND SENT ME HOME. ABOUT 50 MILES LATER THE DRIVE MODE AND SERVICE ENGINE LIGHTS CAME ON AGAIN. ABOUT 50 MILES LATER THEY TURNED OFF ON THEIR OWN, AND ANOTHER 20 MILES LATER THEY CAME BACK ON AGAIN. THE CAR SEEMS TO DRIVE NORMALLY BUT THE DIFFERENT DRIVE MODES SUCH AS "TRACTION +" AREN'T ACCESSIBLE. IT'S BEEN BETWEEN 60-80 DEGREES OUTSIDE & CLEAR ON EACH OCCASION. IT HASN'T TURNED ITSELF OFF AGAIN SINCE THE FIRST TIME.
