2011 Chevrolet Impala

VEHICLE DISPLAYS "REDUCED POWER" "SERVICE STABILITRAK SYSTEM". I REPLACED THE THROTTLE POSITION SWITCH (TPS) AND IT HAS CAME BACK AGAIN. SERVICE LIGHT IS ON AND READS P2138, TPS. ON HUNDREDS OF FORUMS PEOPLE ARE COMPLAINING OF THIS SAME PROBLEM, SHOULDN'T THIS BE RECALLED? ALSO I EVEN CLEANED THE THROTTLE MOTOR AND POSITION SENSOR UNDER THE HOOD, IT SEEMED TO HELP FOR A LITTLE WHILE. *TR

THE CHECK ENGINE LIGHT CAME ON (AND HAD GONE OUT) PREVIOUSLY. DASH SAID "SERVICE STABILITRAC, ENGINE POWER REDUCED" AND A MECHANIC SAID IT WAS A "SENSOR IN THE GAS PEDAL" AND THAT IF IT KEPT HAPPENING WE SHOULD REPLACE IT. I DIDN'T FULLY REALIZE THAT THIS MEANT THAT THE THROTTLE WOULD DISABLE ITSELF WHILE I WAS DRIVING IN MORNING RUSH HOUR TRAFFIC ON THE HIGHWAY IN THE LEFT HAND LANE GOING UP A HILL DOING 60 MPH. THERE WAS TRAFFIC BEHIND ME AND IN OTHER LANE SO I HAD TO PULL INTO THE CENTER SHOULDER OVERTOP OF 5 INCHES OF SNOW AND ICE. IT WAS A STRUGGLE NOT TO HIT THE GUARDRAIL. THERE WAS BARELY ENOUGH ROOM. I JUST MADE IT OVER THE YELLOW LINE. IT WAS 20 DEGREES AND THEN HAD TO WAIT AN HOUR FOR A TOW TRUCK. THE CAR DID START AND DRIVE AT THE GARAGE. THIS MECHANIC REPLACED THE ACCELERATION PEDAL ASSEMBLY. THE ERROR WAS CODE P2122. HE ALSO STATED THAT HE COULD SMELL BURNING WIRES. I HAD SMELLED IT BUT DIDN'T REALIZE WHAT IT WAS. *TR

THE CHECK STABILILINK / REDUCED ENGINE POWER LIGHT CAME ON AT START. AFTER SHUTTING THE VEHICLE DOWN AND RESTARTING THE LIGHT WENT OFF. I WAS TRAVELING ON THE HIGHWAY WHEN THE REDUCED ENGINE POWER LIGHT CAME ON. I PULLED OVER, RESTARTED THE CAR AND IT WAS FINE. AFTER STOPPING AND RESTARTING SEVERAL MORE TIMES, THE ENGINE LIGHT REMAINS ON AND THE CHECK. THE STABILIZING WARNING CONTINUES. THE CAR IS COMPLETELY UNRELIABLE AT THIS TIME. SINCE THIS OCCURRED OVER EASTER, THERE ARE NO MECHANICS AVAILABLE,LEAVING ME WITH NO CAR AND CANCELLED APPOINTMENTS AND LOST WAGES TO START THE WEEK. *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
