2006 PONTIAC G6 BASE 4 CYL HAD STIFF STEERING AND EVENTUALLY LOCKED UP WHILE TURNING GOING 35MPH. HAD TO PULL OVER. RADIO COMPUTER INFORMED ME THAT THE POWER STEREING HAD FAILED. TOOK TO DEALERSHIP WHERE THEY REPLACED THE STEERING MOTOR. 3 MONTHS LATER, THE SAME PROBLEM ONLY WORSE. STEERING COMPLETELY LOCKED UP WHILE GOING 60MPH ON THE HIGHWAY. HIT A MEDIAN, NEARLY CAUSED A PILE UP ON I-69, HAD TO HAVE THE VEHICLE TOWED WHERE THEY WERE UNABLE TO DETERMINE THE CAUSE. *TR
