2010 KIA BORREGO Electrical System Problems

OUR 2009 KIA BORREGO HAS HAD SEVERAL ISSUES. WORST ARE 1) WE PUT VEHICLE IN REVERSE AND BACKED OUT OF GARAGE, WENT TO PUT IN DRIVE AND STARTED DOWN DRIVEWAY. WE FORGOT SOMETHING SO STOPPED AND BACKED UP, UPON PUTTING BACK TO DRIVE WE GOT LOCKED IN NEUTRAL. WE COULD NOT GET CAR INTO REVERSE OR PARK. WE PUSHED THE ENGINE OFF BUTTON WHICH SHUT CAR OFF, BUT STILL WERE STUCK IN NEUTRAL. CAR WOULD NOT START BACK UP. WE HAD TO PRESS BRAKE HARD AND GOT CAR STARTED THEN IT WAS OK. 2) THEN A FEW DAYS LATER THE ENGINE LIGHT CAME ON. THE CAR WAS GOING TO BE DRIVEN TO ANOTHER CITY FOR WORK SO WE TOOK BY KIA. THEY SAID WE COULD DRIVE IT, BUT IT COULD STALL OUT WHILE DRIVING. AT ANY SPEED! WE LEFT AT KIA FOR SERVICE. UNDER WARRANTY, SO NOT EXACTLY WHAT CAUSED...
