2009 KIA RONDO Unknown Or Other Problems

I am reporting premature sub frame corrosion. The corroded area would cause a safety hazard if the corroded part of the frame broke all the way off as a result of hitting a large bump or perhaps a big pothole. Fortunately i discovered the problem when I was getting the tires balanced. I will no longer drive the vehicle until it is repaired safely.

ON THREE OCCASIONS WITHIN THE PAST TWELVE MONTHS, I HAVE COMPLETELY LOST POWER STEERING WHILE DRIVING. THE WHEEL BECOMES ALMOST UNMOVABLE (I AM A STRONG, ADULT MALE). ON ONE OF THESE OCCASIONS, THE WEATHER WAS DAMP AND THE ENGINE ALSO STALLED. FORTUNATELY I WAS ABLE TO MUSCLE AND COAST THE CAR ONTO THE SHOULDER WHERE I WAS ABLE TO RESTART THE CAR AND DRIVE AWAY. ON THE REMAINING TWO OCCASIONS I WAS DRIVING AT 65 MPH ON THE INTERSTATE WHEN THE POWER STEERING CEASED TO WORK. TERRIFYING AND DEADLY. LATEST EVENT WAS MAY 9, 2018.

WHEN KEY IS REMOVED FROM THE IGNITION SWITCH, INDICATES THAT THE KEY IS STILL ON. HAVE TO RESTART AND REMOVE THE KEY TO DISABLE THEM. NAVIGATION UNIT FREEZES. HAVE TO EJECT THE CD AND CLOSE THEM TO ENABLE USE THE NAVIGATION UNIT TOOK THE VEHICLE 3 OR 4 TIMES, DEALER RESPONDING BACK THAT THEY ARE NOT ABLE TO REPLICATE THE ISSUE.
