2011 Chevrolet Impala

I OWN A 2011 CHEVY IMPALA AND FOR THE PAST COUPLE MONTHS ON 6 DIFFERENT OCCASIONS AS I AM DRIVING DOWN THE FREEWAY MY ENGINE POWER IS REDUCED AND "SERVICE STABILITRAK" LIGHT APPEARS. AS I HAVE RESEARCHED AND HAVE FOUND THAT THIS IS A COMMON AND VERY UNSAFE PROBLEM AMONG GM VEHICLES. I HAVE ALSO FOUND THAT THERE IS NO CLEAR SOLUTION TO WHY THIS IS HAPPENING WITH MANY MECHANICS STUMPED AND REPLACING PARTS IN WHICH THE PROBLEM RECURS ONLY A SHORT TIME LATER. I HAVE ALSO FOUND REPLACING WHAT THE DIAGNOSIS OF CODE P2135 SAYS THE PROBLEM STILL MAY NOT BE SOLVED. AS ONE CAN IMAGINE THAT DRIVING DOWN THE FREEWAY WITH A SEMI,HEAVY TRAFFIC,ETC. AND LOSING ENGINE POWER MAY LEAD TO SIGNIFICANT NEGATIVE RESULTS. I HAVE NOT INSTALLED ANY PARTS OTHER THAN TIRES AFTER PURCHASING OF VEHICLE. *TR

MY WIFE WAS DRIVING ON THE HIGHWAY AND OUT OF THE BLUE THE STABILITY CONTROL AND REDUCE ENGINE POWER LIGHT CAME ON THE MESSAGE DISPLAY. THERE WERE NO WEATHER CONDITIONS AT THE TIME. THIS HAS HAPPENED 6 TIMES TOTAL. ONE TIME IT HAPPENED AS SHE WAS WARMING UP THE CAR. ALL OF A SUDDEN IT STARTED SHAKING AND SHE FELT AS IF IT WAS ABOUT TO TAKE OFF INTO SPACE. SHE TURNED IT OFF THREE TIMES - EVEN TRIED TO DRIVE IT AND MOVE TO ANOTHER PARKING PLACE AND TURNED IF OFF AGAIN BEFORE IT FINALLY STOPPED SHAKING. *TR

MY 2011 IMPALA IS READING "SERVICE THROTTLE. REDUCE ENGINE POWER" AND THEN PROCEEDS TO SHUT DOWN. EVEN AFTER REPLACING ACCELERATOR PEDAL POSITION SENSOR, VEHICLE IS STILL READING SAME ERRORS. THIS IS VERY DANGEROUS BECAUSE THERE IS NO LIMITATIONS TO WHEN THE VEHICLE SHUTS OFF. AFTER EXTENSIVE RESEARCH, A LOT OF PEOPLE ARE HAVING THE EXACT SAME ISSUE AND CHEVROLET HASN'T ATTEMPTED TO DO ANYTHING ABOUT IT. PLEASE HELP! *TR

WHILE DRIVING ON CITY BELTWAY, I WAS CHANGING LANES AT 50 -55MPH WHEN MY CAR EXPERIENCE SHUDDER AND THE MESSAGES THAT CAME ON SCREEN WAS ENGINE REDUCING POWER, CHECK STABILITY CONTROL, CHECK TRACTION CONTROL LIGHTS FLASH AND WHAT APPEARED TO BE ROUGH IDLING. THE NEXT INCIDENT HAPPEN OFF AND ON FOR SEVERAL DAYS. THE LAST KNOWN WAS 1/3/2013 630AM AND 115PM I WOULD HAVE TO SSHUT DOWN AND RESTART UNTIL THE MESSAGE DISAPPEARS. THE THING THAT REALLY SHOOK ME UP WAS WHEN I WAS MERGING ONTO THE HIGHWAY IN THE MORNING AROUND 6:45AM THERE WAS A SEMI AND OTHER VEHICLES BEHIND ME SO I ATTEMPTED TO MERGE AT ABOUT 30-50 WHEN THE MESSAGES APPEARED AND THE SEMI WAS PRACTICALLY ON MY TAIL. MY HEART JUMPED OUT MY CHEST BUT I REMAINED CALMED AND LUCKILY THERE WAS A MEDIAN STRIP AHEAD. I ASK MYSELF SITUATION COULD HAVE GONE WRONG AND CAUSED A MAJOR ACCIDENT OR GOTTEN KILLED FROM BEING RAMMED FROM BEHIND ALL BECAUSE I COULD'NT ACCELERATE.I HAVE A SMALL VIDEO TO BACK THIS UP. I TOOK IT TO THE DEALER AND THEY SAID THAT THERE WAS NO RECALL NOTICE AND THAT THEY WOULD NEED TO GET THE CODE AND CHARGE ME 129.00 FOR DIAGNOSTIC. THIS IS CLEARLY A SAFETY ISSUE AND WHO KNOWS HOW MANY WAS KILLED BEHIND THIS. *TR

TL* THE CONTACT OWNS A 2011 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING 35 MPH THE VEHICLE HESITATED. THE CONTACT APPLIED MORE PRESSURE TO THE ACCELERATOR PEDAL AND THE VEHICLE STALLED. THE TRACTION STABILIZER WARNING LIGHT BEGAN TO ILLUMINATE ONE WEEK LATER. THE VEHICLE WAS TAKEN TO A DEALER FOR DIAGNOSIS AND THE CONTACT WAS INFORMED THAT THE ACCELERATOR WOULD NEED TO BE REPLACED.

THE TALL REAR SEAT HEADRESTS SEVERELY OBSCURE VISION TO THE REAR WHEN BACKING UP. THE MIDDLE REAR SEAT HEADREST IS THE WORST OFFENDER, AND COMPLETELY BLOCKS MY REAR VISION TO THE POINT WHERE I CANNOT TELL IF THERE IS A VEHICLE OR OTHER OBJECT BEHIND ME WHILE DRIVING DOWN THE ROAD OR BACKING UP. IT APPEARS THAT THE PROBLEM HAS BEEN RECOGNIZED BY GM AS I HAVE NOTICED THE 2012 IMPALA DOES NOT HAVE THIS CENTER REAR HEADREST! THIS IS AN ACCIDENT WAITING TO HAPPEN AND A RECALL NEEDS TO BE ISSUED FOR THESE OLDER MODEL IMPALAS SO THESE REAR SEAT HEADRESTS CAN BE REMOVED. I ALREADY SUBMITTED A COMPLAINT TO GM (REFERENCE #[XXX]) INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR
