2009 CHEVROLET SILVERADO 2500 Engine Problems

THE ENGINE SHUT OFF ON THE FREEWAY AT SPEED AND I LOST ALL CONTROL OF THE VEHICLES STEERING AND BRAKING. IT SAID IT WAS A CRANKSHAFT POSITION SENSOR PROBLEM. WENT TO THE DEALER AND THEY SAID IT WAS A DIRTY SENSOR. ALSO HAVE HAD AND ON GOING PROBLEM WITH LOW OIL PRESSURE 10 LB AT IDLE AND 20 LB AT SPEED.IT ALSO RUNS VERY ROUGH AT IDLE. ALSO HAVE AN ON GOING PROBLEM WITH NOISE FROM THE TRANSMISSION AND A HARD SHIFTING OR SLIPPING TRANSMISSION. IT ALSO MAKES A LOAD NOISE WHEN TURNING THE STEERING WHEEL WHEN TURNING,AND HAS GOTTEN WORSE OVER TIME.

WAS PASSING A VEHICLE AND THE THROTTLE STUCK WIDE OPEN AFTER I KICKED IT INTO PASSING GEAR, AT ABOUT 90 MPH, AFTER TRYING TO KICK THE THROTTLE OFF, PULLING ON THE FLOOR MAT TO MAKE SURE IT WASN'T THE PROBLEM, I FINALLY PUT BOTH FEET ON THE BRAKE PEDAL AND TRIED TO GET THE PICKUP SLOWED DOWN AS THE ENGINE WAS STILL PULLING HARD, FINALLY AFTER GETTING THE SPEED DOWN TO ABOUT 75-80 MPH THE THROTTLE FINALLY LET GO AND I WAS ABLE TO SLOW THE VEHICLE DOWN, TOOK IT TO THE DEALER WHERE I PURCHASED IT AND THEY COULDN'T GET IT TO DO IT AGAIN, AFTER TALKING TO THE FACTORY PEOPLE THEY DECIDED TO PUT A NEW FOOT PEDDLE ON IT BECAUSE THAT'S WHERE THE BRAINS ARE FOR THE RUN BY WIRE FOR THE ENGINE, TOOK IT HOME AND IT DID IT AGAIN TWO DAYS LATER, TOOK IT BACK...
