2011 Buick Regal Speed Control & Cruise Problems

MIL Lamp is illuminated and cannot be turned off or reset. The code displayed on the scanner is for P2138 "Throttle/Pedal Position Sensor/Switch D/E Voltage Correlation." There is also a "Reduced Engine Power" message on the dashboard. Available for inspection upon request. My safety was put at risk before the vehicle was serviced because the car shut down in the middle of the street with cars behind me. I called a certified mechanic to successfully service the vehicle and he cleared the code. My safety was put at risk again after the car was serviced because the code came back on as I was driving on the highway. Car lost power and speed and as I tried to get the car pulled over with emergency lights on, I was almost hit from behind by 2 other drivers. Problem can be reproduced within 10 minutes. Per the mechanic's request, I am taking my car to a Buick Century GMC dealership on 7/16 @ 12 PM to be serviced. Warning symptoms before code came on happened especially during times of rainfall. Car hesitated to pick up speed. Overconsumption of gas resulting in decreased mileage.

ENGINES STARTED TO PUTTER. THEN ENGINE POWER REDUCED CAME ON. CAR DIED THEN THE SERVICE STABILITRAK CAME ON

THE CAR STALLS WHEN SHIFTING GEARS. AT FIRST, IT WAS ONLY WHEN I WAS STOPPED THEN BEGAN TO DRIVE AND THE CAR WAS SHIFTING INTO FIRST GEAR. HOWEVER, IT RECENTLY GOT WORSE. I WAS RECENTLY ON THE FREEWAY AND WHEN I REACHED 60 MPH, IT STALLED, BEGAN TO SHAKE, AND DECREASE IN SPEED. IT WOULDN'T LET ME ACCELERATE. ONCE I GOT OFF THE FREEWAY AND REACHED UNDER 10 MPH, IT BEGAN TO WORK AGAIN BUT STILL STALLED EVERY TIME IT SHIFTED GEARS. I'VE TAKEN IT TO THE DEALER AND THEY SAY THEY CAN'T FIND ANYTHING WRONG WITH IT.

TL* THE CONTACT OWNS A 2011 BUICK REGAL. THE CONTACT STATED THAT WHILE DRIVING 3 MPH IN A PARKING LOT, THE VEHICLE BEGAN TO ACCELERATE INDEPENDENTLY. THE VEHICLE WAS FINALLY BROUGHT TO A STOP. THE CONTACT STATED THAT A RED WARNING LIGHT WAS BLINKING ON THE SHIFTER PRIOR TO THE FAILURE. THE MANUFACTURER WAS NOTIFIED AND INSTRUCTED THE CONTACT TO TAKE THE VEHICLE TO A DEALER. THE DEALER REPROGRAMMED THE VEHICLE BUT AFTER THE REPAIR, THE FAILURE RECURRED ALONG WITH THE TRUNK OF THE VEHICLE OPENING INDEPENDENTLY. THE MANUFACTURER WAS NOTIFIED AND ADVISED THAT THEY WOULD GET BACK WITH HER AT A LATER DATE. THE VEHICLE HAD NOT BEEN REPAIRED. THE FAILURE AND CURRENT MILEAGE WAS 7,000.

TL* THE CONTACT OWNS A 2011 BUICK REGAL. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 5 MPH THE CONTACT TURNED INTO A PARKING SPACE WHEN THE VEHICLE SUDDENLY ACCELERATED INDEPENDENTLY AND CRASHED INTO THE WALL OF A BUILDING. THE CONTACT WAS ABLE TO DRIVE THE VEHICLE FROM THE SCENE. THE VEHICLE WAS TAKEN TO AN AUTO SHOP FOR REPAIR TO THE UNDER CARRIAGE DAMAGE CAUSED BY THE CRASH. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 7,350.

TL* THE CONTACT OWNS A 2011 BUICK REGAL. THE CONTACT WAS DRIVING LESS THAN 5 MPH IN A PARKING LOT WHEN THE VEHICLE INCREASED ACCELERATION AND CRASHED INTO ANOTHER VEHICLE. A POLICE REPORT WAS NOT FILED OF THE INCIDENT AND THERE WERE NO PERSONAL INJURIES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC FOR REPAIR. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 15,307.

PURCHASED CAR IN SUMMER OF 2011. DURING THE FIRST COLD WEATHER CAR WOULD GIVE A WARNING TO SERVICE STABILITI TRAC AND THAT THE ENGINE POWER HAD BEEN REDUCED. I DECIDED TO PULL OVER AND RESTART THE VEHICLE AND IT WOULD RESET THE COMPUTER AND THE WARNING LIGHTS WOULD TURN OFF. I TOOK THIS TO THE DEALER AND THEY COULD NOT REPLICATE THE ISSUE. I STARTED TO LET THE CAR WARM UP IN THE WINTER AND THIS SEEMED TO HELP UNTIL RECENTLY. WITHIN THE LAST FEW WEEKS I HAVE BEEN HAVING SIMILAR PROBLEMS EVEN AFTER LETTING THE CAR WARM UP. THE CAR WILL AUTOMATICALLY REDUCE ENGINE POWER EVEN WHILE ON THE HIGHWAY MAKING IT DIFFICULT TO GET OUT OF THE WAY OF TRAFFIC. AFTER THESE INCIDENTS THE CHECK ENGINE LIGHT WILL COME ON BUT WILL GO OFF AFTER TURNING THE CAR OFF AND RESTARTING. I HAVE CONTACTED ONSTAR AND THEY TELL ME THE SAME THING THAT THE WARNING LIGHTS DO. I HAVE ALSO HAD ISSUES WITH THE CAR TRYING TO ACCELERATE ON ITS OWN WHILE AT A STOPLIGHT. AFTER GOING TO THE DEALER AND HAVING THEM NOT ABLE TO DIAGNOSE THE PROBLEM OR TRY TO REPAIR IT AND NOT FIX THE ISSUES, I FEEL AT A LOSS OF WHAT TO DO AT THIS POINT. I DO NOT HAVE THE TIME OR MONEY TO KEEP GOING TO THE DEALER ONLY TO LEAVE WITH THE SAME PROBLEMS. I WOULD THINK THAT THE MANUFACTURER WOULD BE MORE INCLINED TO FIX THESE ISSUE BEFORE PEOPLE ARE INJURED OR ANY FATALITIES OCCUR DUE TO THEIR NEGLIGENCE. I FEEL THAT AFTER READING ABOUT OTHER PEOPLE'S SIMILAR ISSUES THAT THIS IS SOMETHING THAT SHOULD CALL FOR A RECALL. *TR
