I HAVE BEEN HAVING POWERS STEERING PROBLEMS WITH MY CAR FOR MONTHS. POWER STEERING LIGHT COMES ON, THE WHEEL JERKS MAKING IT HARD TO CONTROL SOMETIMES. AT HIGHER SPEEDS IT SEEMED TO BE WORSE, AND THE STEERING WHEEL WILL VIBRATE. I DID BRING IT TO A DEALER THAT TOLD ME THERE WAS EXTENDED WARRANTY COVERAGE ON 2005 AND 2006 G6 MODELS , BUT NOT 2007. I WOULD BE RESPONSIBLE FOR REPAIRS. YESTERDAY I WAS IN A CAR ACCIDENT AND I BELIEVE THE STEERING PROBLEM PLAYED A ROLE. THE WHEEL WAS JERKING, PRIOR TO THE ACCIDENT. WE WERE DRIVING ON AN INTERSTATE TRAVELING AT A FASTER SPEED. I DON'T KNOW HOW I ENDED UP BOUNCING OFF THE BACK TIRE OF A SEMI TRUCK IN THE LANE NEXT TO ME, BUT I WAS FIGHTING THE CAR TO GAIN CONTROL OF THE VEHICLE AGAIN. NOT ONLY WITH ALL THE "NORMAL" PHYSICAL FORCES, BUT THE CAR STILL WANTED TO GO ITS OWN WAY. OVER COMPENSATING AND FISHTAILING THE WHOLE WAY. THANKFULLY WE ARE ALL ALIVE, THE CAR PROBABLY WILL BE A COMPLETE LOSS. *TR
