2012 HYUNDAI VELOSTER Fuelpropulsion System Problems

After an update for a recall for brake issues, the dealership updated the knock sensor update without my consent. After the knock sensor software was installed, my 2012 Hyundai veloster will not operate without going into protection mode. Hyundai states that they can not reverse the software update to make my vehicle operable again. This has already come up as a safety concern as my wife was on the interstate when the vehicle shut down in 70+ mph traffic.

MY CAR IS HAVING ISSUES DESCRIBING WHAT IS HAPPENING IN THE RECALL, THE ENGINE IS LOUDER THAN WHEN I GO OUT IT SOUNDS LIKE YOU'RE KNOCKING NOISE AND I JUST GOT IT IN SEPTEMBER. I NEED TO SPEAK WITH SOMEBODY ABOUT THIS SINCE IT'S NOT LISTED ON THE RECALL

THE FUMES WERE OVERWHELMING, CLOSE TO HOME SO DROVE IT HOME WITH ALL WINDOWS OPEN TO VENT THE SMELL. CALLED ROADSIDE ASSISTANCE AND HAD VEHICLE TOWED TO DEALERSHIP FOR REPAIRS. PICKED UP VEHICLE NEXT DAY AND THE DEALER DID NOTHING, SAID THIS WAS NORMAL, AND TO RUN THE RE-CIRCULATE AS TOLD BEFORE. SPOKE WITH SERVICE MANAGER AT HENDERSON HYUNDAI WHO GAVE ME A TWO PAGE DOCUMENT THAT STATED " SEVERAL FACTORS MUST BE PRESENT AT THE SAME TIME IN ORDER FOR THIS TO OCCUR. SOME EXAMPLES OF THESE CONDITIONS ARE, HIGH AMBIENT TEMPERATURE (100F +), HIGH ALTITUDE, POOR FUEL QUALITY, LOW FUEL LEVEL IN THE GAS TANK, EXTENDED IDLING, SLOW TRAFFIC OR...
