2011 Chevrolet Impala

ON TWO DIFFERENT OCCASIONS, ONCE ABOUT A YEAR AGO AND AGAIN TODAY, MY 2011 CHEV IMPALA LTZ DISPLAYED A SERIES OF ROTATING ALERT MESSAGES -- 1. SERVICE TRACTION CONTROL 2. SERVICE STABILITRAK 3. ENGINE POWER IS REDUCED. I WAS DRIVING ABOUT 45 MILES PER HOUR ON AN OPEN ROAD WHEN ALL OF A SUDDEN THE ENGINE STARTED RUNNING VERY ROUGHLY AND SLOWED DOWN AND THE ABOVE 3 MESSAGES REPEATEDLY DISPLAYED ONE AFTER THE OTHER. ALSO 2 YELLOW LIGHTS WERE FLASHING AND THEN REMAINED ON -- THE CHECK ENGINE LIGHT AND THE TRACTION CONTROL LIGHT (I THINK). WHEN I REPORTED THIS PROBLEM TO THE CHEV DEALERSHIP A YEAR AGO, I WAS TOLD THAT BECAUSE THE WARNING LIGHTS AND MESSAGES COULD NOT BE REPRODUCED IN THE SERVICE DEPARTMENT, THERE WAS NOTHING THAT THEY COULD DO. (AND I UNDERSTAND THAT IF IT ISN'T BROKEN WHEN I TAKE IT IN, THE SERVICE DEPT WOULD MOST CHALLENGED TO FIX IT.) TODAY, WHEN THIS HAPPENED I WAS ABLE TO GET THE CAR TO A SAFE PLACE TO PARK. I TURNED OFF THE IGNITION, WAITED A MOMENT AND THEN RESTARTED THE CAR. THE SAME 3 MESSAGES WERE DISPLAYED WITH THE TWO YELLOW LIGHTS STAYING ON. WHEN I RESTARTED THE CAR 3 OR 4 HOURS LATER, ONLY THE CHECK ENGINE LIGHT IS DISPLAYED. THE 3 REFERENCED ALERTS WERE NOT DISPLAYED. I AM GETTING READY TO TAKE THE CAR TO THE DEALERSHIP AGAIN WITH THIS PROBLEM. DO YOU HAVE ANY ADVICE AS TO HOW TO PROCEED?

TL* THE CONTACT OWNS A 2011 CHEVROLET IMPALA. WHILE DRIVING 45 MPH, THE TRACTION CONTROL, SERVICE STABILITY, CHECK ENGINE, AND ENGINE POWER INDICATORS ILLUMINATED. THE VEHICLE JERKED AND THE CONTACT DECELERATED THE VEHICLE TO 10 MPH; HOWEVER, THE SPEEDOMETER INDICATED 40 MPH. THE VEHICLE WAS NOT TAKEN TO THE DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS CONTACTED, BUT THERE WAS NO ANSWER. THE APPROXIMATE FAILURE MILEAGE WAS 94,000. THE VIN WAS NOT AVAILABLE.

WHILE DRIVING ON THE EXPRESSWAY AT ABOUT 65MPH MY CAR SUDDENLY ALERTED "SERVICE STABILTRAK, SERVICE TRACTION CONTROL, ENGINE POWER REDUCED" AND I WAS NOT ABLE TO UTILIZE CRUISE CONTROL ANYMORE AND IT STARTED TO SLOW DOWN TO APPROXIMATELY 40MPH. THEN MY VEHICLE STARTED TO JERKILY MOVE & THEN IT ALERTED "STARTER DISABLED SERVICE THROTTLE" AND MY CAR SHUT DOWN (STEERING ALTERED & CAR SHUT OFF). I WAS ABLE TO MANEUVER TO THE SIDE OF THE ROAD & TRIED TO RESTART MY CAR (UNSUCCESSFULLY FOR APPROXIMATELY 10 MINUTES). DID I MENTION I HAD MY 2 CHILDREN IN THE CAR WITH ME WHEN THIS HAPPENED? THIS WAS TERRIFYING AS MY CAR JUST STOPPED-I HAD MINIMAL WARNING & WHEN TRAVELING ON THE INTERSTATE IT COULD'VE BEEN A LOT WORSE. AFTER READING HOW FREQUENTLY THIS HAPPENS, WHY HASN'T IT BEEN RECALLED?

MY SERVICE STABILITRACK, REDUCE ENGINE POWER LIGHT CAME ON WHILE I WAS EXITING THE FREEWAY. WHEN THIS HAPPENED I HAD ALMOST NO BRAKE PEDAL. I COULDN'T STOP AT THE LIGHT AT THE END OF THE EXIT, LUCKILY NO OTHER CARS WERE AROUND. IF I HAD BEEN ON A MAIN STREET AT 45MPR AND HAD TO STOP FOR A RED LIGHT I WOULD HAVE NEVER STOPPED ON TIME. I'M VERY LUCKY NO CARS WERE AT THE LIGHT WAITING OR COMING IN A DIFFERENT DIRECTION WITH THE GREEN LIGHT. I SEE THIS PROBLEM ALL OVER EDMUNDS AND ON YOU TUBE AND AS FAR AS I CAN TELL IT'S 100% CHEVROLET. HOW CAN THIS NOT BE A RECALL. THERE ARE DOZENS AND DOZENS OF THE SAME COMPLAINT ON EDMUNDS AND YOU TUBE. IT SEEMS LIKE EVERY YOU TUBE VIDEO HAS A DIFFERENT FIX FOR THE PROBLEM....FROM PULLING OUT THE FUSE TO THE STABILITRACK TO OVER A THOUSAND DOLLARS IN REPAIRS. DOES THERE HAVE TO BE A DEATH TO GET THE ATTENTION OF CHEVROLET. THE LIGHT HAD COME ON A FEW TIMES BEFORE BUT THIS WAS THE FIRST TIME IT HAPPENED WHILE I WAS DRIVING. USUALLY IT CAME ON AND I WOULD TURN THE CAR OFF FOR A FEW MINUTES AND IT WOULD BE FINE......SO HOW COULD THIS BE ANYTHING BUT A MALFUNCTION IF IT GOES OFF AND ON AT ANY WHIM. THEY MUST KNOW ABOUT THIS PROBLEM AS IT SEEMS TO BE VERY PREVALENT AND AGAIN FROM WHAT I HAVE READ IT'S ALWAYS A CHEVROLET.
