2011 Chevrolet Silverado

DRIVING ABOUT 60 MPH ABOUT 10 MILES INTO THE TRIP WHEN THE TRUCK LOST SPEED, THE ABS BRAKES DID A SLIGHT ON AND OFF PULSATING EVERY COUPLE OF SECONDS, THE ENGINE WAS RUNNING ROUGH AND GIVING IT GAS THE ENGINE REVVED UP BUT WOULDN'T GO ANYWHERE. SPEED DROPPED DOWN TO 35 OR 40 MPH AND WOULDN'T GO ANY FASTER. THE DASH INDICATOR SHOWED MESSAGES STATING STABILITRAK TRACTION CONTROL TURNED OFF AND CHECK ENGINE LIGHT IS ON. IT JOLTED REAL HARD WHEN IT SHIFTS GEARS. WHEN I MASHED THE BRAKE IT DIDN'T WANT TO COME TO A COMPLETE STOP WITHOUT PRESSING THE BRAKES TO HOLD THE TRUCK THERE. I PULLED INTO A STORE POPPED THE HOOD AND FINDING NOTHING I TURNED THE TRUCK OFF FOR A FEW SECONDS AND RESTARTED IT BUT NOTHING CHANGED AND THE ERROR MESSAGES WERE STILL BEING DISPLAYED. THE TRUCKS ENGINE WAS RUNNING ROUGH. I HEADED HOME AND IT DIDN'T HAVE ANY POWER AND JOLTED HARD AS IT SHIFTED GEARS. I COUDLN'T GO BUT 35 OR 40 MPH ON THE LEVEL GROUND. IF I WENT UP A SLIGHT HILL THE TRUCK SLOWED DOWN MORE UNTIL I GOT PAST THE HILL. I GAVE IT GAS AND THE ENGINE WOULD REV UP BUT HAD NO POWER AND WOULDN'T GO 35 OR 40 MPH. I PARKED THE TRUCK IN THE GARAGE AND IN 10 MINUTES I WENT TO START IT TO GET THE ERROR MESSAGES AND IT STARTED UP FINE AND THE ENGINE WASN'T RUNNING ROUGH. I DROVE IT 1/2 MILE DOWN THE ROAD AND BACK AND IT RAN PERFECT. I GOOGLED THE ERROR MESSAGES AND FOUND ALOT OF COMPLAINTS AND COMMENTS ABOUT THIS ISSUE ON THE CHEVROLET FORUM WEBSITE. NO RECALL INFORMATION JUST ALOT OF PEOPLE EXPERIENCING THE SAME ISSUE AND ALOT WORSE CASES THAT ALMOST CAUSED ACCIDENTS. IS THERE A RECALL ON THIS ISSUE? I READ THAT I WILL PROBABLY HAVE THE ISSUE AGAIN BECAUSE AFTER IT SITS FOR 10 MIN IT PROBABLY WON'T HAVE A PROBLEM UNTIL A FEW MINUTES OR DAYS LATER. I CAN ONLY HOPE DOESN'T CAUSE ME TO HAVE A WRECK AND KILL MYSELF OR SOMEONE ELSE. THIS IS A MAJOR ISSUE AND SHOULD BE RECALLED TO FIX THE PROBLEM. *TR

TL* THE CONTACT OWNS A 2011 CHEVROLET SILVERADO. THE CONTACT STATED THAT THE VEHICLE FAILED TO RESPOND TO ACCELERATION ATTEMPTS. AFTER CONTINUALLY DEPRESSING THE ACCELERATOR PEDAL, THE VEHICLE SUDDENLY JERKED FORWARD. ADDITIONALLY, THE CONTACT NOTICED THE VEHICLE HESITATED WHEN ACCELERATING. THE VEHICLE WAS TAKEN TO THE DEALER FOR DIAGNOSTIC TESTING. THE TECHNICIAN WAS UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 22,000.

#1. VEHICLE ACCELERATES WHEN LETTING OFF GAS, EVEN WHILE GOING UPHILL THE VEHICLE WILL ACCELERATE. YOU CAN GO UP A STEEP HILL WITHOUT TOUCHING THE GAS. BROUGHT THE VEHICLE TO THE DEALERSHIP THEY REPLACED, THE THROTTLE BODY, GAS PEDAL ASSEMBLY. THEY REINSTALLED THE ORIGINAL PARTS AND TOLD US THAT THIS WAS NORMAL. WE DROVE OTHER 2011 CHEVY SILVERADO'S WHICH DID NOT DO THE SAME THING. THE DEALERSHIP TOLD US THAT ALL THE 2011 CHEVY SILVERADO'S ACCELERATE ON THEIR OWN. #2. THERE IS A CLUNKING NOISE FROM THE REAR WHEN DRIVING OVER BUMPS. THE DEALERSHIP SAID THIS IS NORMAL BACKLASH, AND DID NOT DO ANYTHING. *KB
