2006 HUMMER H2 Power Trainautomatic Transmission Problems

I PURCHASED A 2006 HUMMER H2 AT CERRITOS HUMMER. I CURRENTLY HAVE ALMOST 55,000 MILES. TODAY I WAS PARKING MY CAR AND NOTICED THE STEERING WAS EXTREMELY HARD TO TURN. ALSO THE BRAKES WERE REALLY WEAK. I USED ALL THE ENERGY I HAD TO GET INTO A GAS STATION DRIVEWAY. I DROVE ABOUT 1 BLOCK BECAUSE I NEEDED GAS WHERE I NOTICED OIL DROPPING UNDER THE CAR. I CHECKED UNDER THE HOOD AND THE OIL WAS COMING OUT NEAR THE POWER STEERING PUMP. I OPENED THE POWER STEERING RESERVOIR AND SAW THAT THERE WAS VERY LITTLE OIL BECAUSE IT HAD DROPPED UNDER MY CAR. MY STEERING IS TOO HARD TO TURN AND THE BRAKES ARE ALMOST NON EXISTENT PULLING INTO THE GAS STATION. I CALLED CERRITOS HUMMER AND TALKED TO THEIR SERVICE MANAGER AND HE SAID I WAS PAST WARRANTY. I TOLD HIM THAT THERE WAS A RECALL ON THIS...
