2011 Chevrolet Silverado 1500 acceleration problems

VEHICLE SPEED CONTROL

**randomly at any given speed ** First the radio system will randomly turn off then moments later… stabiliTrak off flashes followed by abs and traction control lights on dash then suddenly my Chevrolet Silverado has a mind of its own ! The door locks will flicker uncontrollably , and the vehicle just suddenly has a loss of power while rpms and gauges are continuously moving while you are unable to even move the vehicle .. this is a ongoing problem since 2019 , that no one seems to have an answer too .. I’ve taken it to 3 different mechanics and still no answers … when it first started happening it was super random and would happen a few times a day but then not happen for months on end then all of the sudden now it is happening several days a week .. I’m currently scared to even drive it which is horrible considering the amount of money I’ve put into this truck .. it has only 100k miles but somehow I am stuck using my dads old truck with 330k miles on it which seems to be more reliable and is 12 years older … sucks to pay over 500$ a month for “ your dream vehicle “ that you can’t even drive or get any real answers to what or where the problem is coming from … seems that thousands of people online have the same problem but yet no one has any solution .. Now that I’ve almost been in 3 serious accidents I decided I have to say something, 2 of these times were over 70 mph on a California freeway !!! Something must be done !

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.

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.

THIS IS A DEALER DEMO VEHICLE, FIRST 2235 MILES WERE DEMO. DURING MY FIRST MORNING (12HOURS AFTER PICKING UP AT DEALER) OF OWNERSHIP I WAS DESCENDING DOWN A HILL WITH THE CRUISE ON, AND THE VEHICLE PROCEEDED TO OVER SPEED APPROXIMATELY 5-7MPH. I TRAVEL THIS HILL BOTH WAYS TO/FROM WORK DAILY AND THIS HAPPENS EVERYTIME. I THOUGH THIS MIGHT BE AN ABNORMAL ADJUSTMENT WITHIN THE COMPUTER/ETC SO WHILE TAKING IN TO THE DEALER FOR A TPMS (TIRE PRESSURE MONITOR SYSTEM) ISSUE I MENTIONED THE OVERSPEED ISSUE TO THE SERVICE WRITE UP AND THEY SAID THAT IT WAS NORMAL. I DON'T AGREE, BUT MAYBE IT IS. IT DOES ADJUST BACK TO NORMAL CRUISE SET SPEED BUT IS UNIQUE. I HAD A 2002 DODGE RAM 1500 PREVIOUSLY AND IT DID NOT DO THIS, AND I HAVE DROVE OTR (OVER THE ROAD) SEMI-TRUCKS AND KNOW THE DIFFERENCE WITH OVERSPEED BEING NORMAL AND ABNORMAL. I WOULD LIKE THIS TO BE LOOKED INTO, AS IT COULD BE A HAZARD THAT COULD LEAD TO UNSAFE SITUATION.

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.
