2011 Chevrolet Silverado Speed Control & Cruise Problems

I WAS MAKING A TURN WHILE PUSHING ON THE GAS PEDAL LIGHTLY, AND ALL OF SUDDEN THE GAS PEDAL WENT TO THE FLOOR WITHOUT PRESSING ON IT AND THE PEDAL GOT STUCK. THE ENGINE RACED UP TO OVER 5000 RPM AND ABOUT 60 MPH AROUND A TURN BECAUSE IT WOULD NOT SLOW DOWN. I HAD TOO KEEP TAPPING ON THE GAS PEDAL TO RELEASE IT. ALSO MY FOOT WAS ON THE BREAK.

ONE NIGHT ON THE WAY HOME FROM WORK, I WAS DRIVING 60MPH AND ALL OF THE SUDDEN MY TRUCK HYDROPLANED. I MANAGED TO GET THE TRUCK STRAIGHT AND REGAIN CONTROL OF THE VEHICLE. ABOUT A WEEK LATER, AS I'M HEADING HOME ALL OF THE SUDDEN MY ABS, BRAKE, AND TRACTION CONTROL LIGHTS ALL ILLUMINATED. THE DIC READS SERVICE STABILITRAK AND SERVICE TRACTION CONTROL, THEN IT WILL DISPLAY STABILITRAK OFF AND TRACTION CONTROL OFF. I HAD THE CODES READ AND MY TROUBLE CODE WAS P069E - FUEL PUMP CONTROL MODULE REQUESTED MIL ILLUMINATION AND U0073 - CONTROL MODULE COMMUNICATION BUS A OFF. ALL THOSE LIGHTS MENTIONED ABOVE HAVE BEEN ON FOR ABOUT A MONTH. I LOOKED UP INFORMATION ABOUT THE FPCM AND FOUND OUT ABOUT GM RECALL 14515, I ENTERED MY VIN BUT THE ONLY RECALL THAT CAME UP WAS FOR THE TAKATA AIRBAG RECALL. AS I READ THROUGH THE 14515 RECALL, I FEEL MY TRUCK IS AFFECTED BY IT BECAUSE, WHILE DRIVING THE TRUCK MY SPEEDOMETER JUMPS ALL AROUND AND IS NOT STABLE. ALSO, WHEN I TRY TO ACCELERATE, IT FEELS LIKE THE ENGINE STALLS AND THERE'S NO POWER THERE. OTHER TIMES, IT WILL DOWN SHIFT TO INCREASE RPMS, BUT THEN SOON SHIFT GEARS INTO A HIGHER GEAR THEN SHIFT BACK INTO A LOW GEAR AND REPEAT THIS UNTIL I LET OFF THE PEDAL. MY TOW HAUL MODE WILL NOT STAY ENGAGED, CRUISE CONTROL WILL NOT STAY ENGAGED, AND MOST OF THE TIME MY TRUCK WON'T EVEN START WHEN TRYING TO USE THE REMOTE START, INSTEAD LIGHTS JUST FLASH AS I'M HOLDING DOWN THE START BUTTON ON THE KEY FOB. THE TRUCK FEELS REALLY SLUGGISH ALMOST LIKE THERE'S NO POWER, IT SEEMS LIKE IT HUNTS FOR THE RIGHT GEARS WHILE DRIVING. OVERALL IT JUST FEELS UNSAFE TO DRIVE.

CONSUMER WRITES IN REGARDS TO THE VEHICLE THROTTLE POSITION SENSOR RECALL NOTICE. *SMD THE LETTER ADVISED CONSUMERS NOT TO TAKE THEIR VEHICLE TO DEALER, UNLESS THEY EXPERIENCED THE PROBLEM.

TL* THE CONTACT OWNS A 2011 CHEVROLET SILVERADO 1500. THE CONTACT STATED THAT THE VEHICLE WOULD UNEXPECTEDLY ACCELERATE WITHOUT WARNING WHETHER THE VEHICLE WAS STOPPED, IN DRIVE OR REVERSE. IN ADDITION, THE ENGINE RPMS WOULD EXHIBIT AN ABNORMAL INCREASE OF 2000 OR MORE WHEN THE FAILURE OCCURRED. ON ONE OCCASION, THE VEHICLE ABNORMALLY ACCELERATED AND THE CONTACT WAS UNABLE TO STOP THE UNINTENDED ACCELERATION. THE CONTACT CRASHED INTO A ROAD STUMP. FIVE PASSENGERS SUSTAINED MINOR INJURIES AND A POLICE REPORT WAS FILED. THE DEALER INSPECTED THE VEHICLE, BUT WAS UNABLE TO DIAGNOSE THE FAILURE. THE MANUFACTURER WAS NOT CONTACTED AND THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 14,000 AND THE CURRENT MILEAGE WAS 14,100.

SPEED CONTROL (CRUISE) DOES NOT HOLD. WHILE GOING DOWN AN INCLINE FROM THE MOUNTAINS, CRUISE CONTROL WAS SET FOR 65 MPH, AND THE VEHICLE INCREASED SPEED TO 85+ MPG BEFORE APPLYING BRAKE TO SLOW DOWN. CALLED DEALERSHIP AND TOOK VEHICLE TO BE CHECKED IN REGARDS TO THIS INCIDENT, AND THEY STATED THAT DUE TO THE DEPARTMENT OF TRANSPORTATION, NEW EMISSION STANDARDS THAT TRANSMISSION WAS MADE NOT TO HOLD SO AS NOT TO INCREASE CARBON FOOTPRINT. THIS CAUSES A VERY UNSAFE CONDITION WHEN DRIVING WHEN THE CRUISE CONTROL IS ENGAGED. *TR

MY 2011 CHEVROLET SILVERADO 1500 HAS UNWANTED ACCELERATION. ITS BEEN HAPPENING FOR APPRX A MONTH, ON AND OFF. ON TUESDAY 10/4/2011 I WAS LEAVING MY PARKING SPACE AT WORK, I HAD MY FOOT ON THE BRAKE AS I WAS TURNING OUT OF THE SPACE, THE VEHICLE JUST TOOK OFF - ACCELERATING WITHOUT TOUCHING THE GAS. I THEN HIT THE BRAKE WHICH STOPPED THE VEHICLE. I THEN GOT ON THE HIGHWAY - (I-94) TO HEAD HOME, WHILE DRIVING ON I-94 MY VEHICLE LUNGED FORWARD NEARLY STRIKING THE VEHICLE IN FRONT OF ME. I THEN BACKED OFF AND KEPT A SAFE DISTANCE IN THE EVENT THAT IT HAPPENED AGAIN, SURE ENOUGH - MY VEHICLE STARTED ACCELERATING ON ITS OWN. I REALIZED IT WAS DOING IT AND HAD ENOUGH DISTANCE BETWEEN ME AND THE OTHER VEHICLES AHEAD, SO I ALLOWED THE VEHICLE TO TAKE OFF. MY SILVERADO GOT UP TO ABOUT 1500 RPMS AT 60MPH, I CLEARLY HAD MY FOOT OFF THE BRAKE AND THE GAS, FEET FLAT ON THE FLOOR. I ALLOWED IT TO ACCELERATE ON ITS OWN FOR APPRX 1 MINUTE BUT THEN HAD TO STOP. IT IS CLEARLY DRIVING ITSELF. I DROVE THE TRUCK STRAIGHT TO THE DEALERSHIP AND LEFT IT FOR THE SHOP TO LOOK AT THE NEXT DAY. THE SERVICE DEPT COULD NOT RE-CREATE THE PROBLEM, GO FIGURE. IN THE PAST MONTH I'VE NEARLY HIT SEVERAL PARKED CARS WHEN PULLING INTO PARKING SPACES AS THE VEHICLE TAKES OFF ACCELERATING, IN THESE EVENTS I WAS ALSO ABLE TO STOP THE VEHICLE W THE BRAKE. *TR
