I WAS GOING DOWN THE HIGHWAY AT 55 MPH AND IT JUST CUTS OFF, THE ENGINE STOPS. IT HAS DOWN THIS SEVERAL TIMES ON THE HIGHWAY JUST CUTS OFF. WONT GO, AND ENGINE LIGHT COMES ON. I PULL OFF THE ROAD AND LET IT SIT FOR AWHILE AND THEN START THE CAR AND IT DOES FINE FOR AWHILE . UNTIL THE NEXT TIME IT DOES IT AGAIN, I HAVE HAD IT TO THE KIA DEALER THREE TIMES . THE FIRST TIME I HAD IT TOWED THERE, IT IS STILL UNDER WARRANTY. THEY CANT SEEM TO FIGURE IT OUT. I HAVE RECEIVED A LETTER FROM KIA TELLING ME THAT OTHER KIA OWNERS ARE HAVING THIS PROBLEM AND I SHOULD TAKE IT IN TO HAVE IT CHECKED. I HAVE DONE SO BUT STILL NOT FIXED. I GOT REAR ENDED BECAUSE THE ENGINE JUST STOPPED, THIS IS VERY DANGEROUS PROBLEM!!! *TR
