2011 CHEVROLET IMPALA Engine Problems

GOT A MESSAGE ON MY DASH A FEW MONTHS AGO ABOUT "SERVICE TRACTION CONTROL" WHILE DRIVING. TRACTION CONTROL LIGHT LIT UP ALSO. PARKED CAR AND TURNED CAR OFF THEN ON...MESSAGE GONE. TOOK IT INTO SERVICE...SHOWED NO ERROR CODES. TODAY (5/2/16), IT DID IT AGAIN WITH THE TRACTION CONTROL LIGHT AND THE CHECK ENGINE LIGHT SIMULTANEOUSLY LIGHTING UP. "SERVICE STABILITRAK", SERVICE TRACTION CONTROL", AND "ENGINE POWER IS RECUDED" ARE THE MESSAGES I GOT TODAY ALONG WITH THE CHECK ENGINE LIGHT AND THE TRACTION CONTROL LIGHT BEING ON. I HAD JUST GOTTEN OFF THE HIGHWAY SO I WASN'T GOING FAST WHEN THIS HAPPENED. I WAS CLOSE TO WORK SO I PARKED IT AT WORK. TURNED THE CAR OFF THEN ON AGAIN AND THE MESSAGES WERE GONE AND TRACTION CONTROL LIGHT WAS OFF BUT CHECK ENGINE LIGHT STAYED ON. TURNED CAR ON AGAIN AT LUNCH 1.5 HOURS LATER AND THE CHECK ENGINE LIGHT...

VEHICLE SLOWED ON HIGHWAY, REDUCED ENGINE POWER WARNING MESSAGE AND STABILITRAK MEASSAGE DISPLAYED ALSO ENGINE INDICATOR LIGHT IS ON.

WHILE DRIVING THE TRACTION CONTROL,STABILIZER,ENGINE POWER WARNING ALL COME ON AND THE CHECK ENGINE LIGHT COMES ON AND SOMETIMES THE ENGINE TURNS OFF. PULL OFF ROAD, WILL NOT START THEN MINUTES LATER IT STARTS. CHECK ENGINE LIGHT STAYS ON. AFTER MULTIPLE STARTS THE CHECK ENGINE LIGHT GOES OUT . I HAVE READ MULTIPLE COMPLAINTS ABOUT THIS ,YET THE NOTHING IS BEING DONE. TO REPAIR THIS PROBLEM. THE EFFECTS OF THIS IS THE SAME AS THE IGNITION TURNING OFF. PENDING ON TRAFFIC. THIS COULD BE DEADLY. THIS HAS HAPPENED ALOT.

I BEGIN NOTICING ISSUES WHEN TAKING OFF FROM A COMPLETE STOP WHERE THE VEHICLE WOULD LUNGE FORWARD LIKE IT COULDN'T SHIFT INTO FIRST GEAR. I HAD THAT CHECKED AND NOTHING SHOWED AS AN ISSUE, SO THE MECHANIC SAID IT HAD TO BE ELECTRICAL. THIS WEEKEND I AM DRIVING IT AND AFTER 25 MINUTES IN THE CAR THE CHECK ENGINE LIGHT COMES ON, AS DOES THE NOTICE THAT MY ENGINE POWER HAS BEEN REDUCED, AND TO SERVICE THE STABILITY TRACTION CONTROL SYSTEM. I WAS COMING TO A STOP LIGHT WHEN IT CAME ON AND I PULLED OFF TO TURN OFF THE CAR AND RESTART IT AS THAT WOULD WORK WHEN IT FAILED BEFORE TO RESET THE SYSTEM. IT DIDN'T RESET AND I HAD TO DRIVE IT WITH REDUCED POWER THE REST OF THE WAY TO MY DESTINATION. I HAD THIS FIXED A COUPLE YEARS AGO. I DID GET A NOTICE FROM...

SERVICE TRACTION CONTROL AND CHECK ENGINE LIGHTS CAME ON THIS MORNING. THEN A MESSAGE SAYING MY ENGINE POWER IS REDUCING. I JUST BOUGHT THIS CAR 3 WEEKS AGO. I CALLED GM CUSTOMER SERVICE AND THEY TOLD ME THERE WAS NOTHING THEY COULD DO, EVEN THOUGH THERE WAS A RECALL REGARDING THIS BECAUSE IT WAS OVER THE 120000 MILE WARRANTY (BUT I JUST BOUGHT THIS CAR 3 WEEKS AGO!!!)

STARTED SEEING ERROR MESSAGE THIS MORNING ON START UP OF THE CAR: ENGINE POWER REDUCED SERVICE TRACTION CONTROL SERVICE STABILTRAK EXPERIENCED REDUCED ENGINE POWER, TRACTION LIGHT ON, ENGINE LIGHT ON

I HAVE PROBLEM WITH THE STABILITRAK/TRACTION CONTROL ON A 2011 IMPALA WITH 120,000 MILES. I HAVE FOUND OTHER PEOPLE FROM ALL OVER THE COUNTRY WITH THE SAME PROBLEM. I HAVE TAKEN IT TO 3 DIFFERENT MECHANICS AND THEY ARE ALL UNSURE AS TO WHAT IT IS. I HAVE PUT A NEW THROTTLE BODY IN, NEW SPARK PLUGS, CHANGE MY OIL FAITHFULLY EVERY 3,000 MILES. IT CONTINUES TO FLASH THE MESSAGE TO ME, DOES NOT HAVE THE SAME ACCELERATION, IS VERY UNPREDICTABLE AS FAR AS REDUCING MY ENGINE POWER AT ANY GIVEN TIME. THIS HAPPENS WHEN I'M DRIVING DOWN THE ROAD AND EVEN WHEN I JUST START MY CAR. I HAVE TO TURN CAR OFF, LET IT SIT FOR A FEW MINUTES AND THEN IT SEEMS TO RESET BUT THE ENGINE LIGHT STAYS ON FOR A FEW DAYS. THIS NEEDS TO BE ADDRESSED WITH AS MANY COMPLAINTS I AM READING ABOUT!

TL* THE CONTACT OWNS A 2011 CHEVROLET IMPALA. WHILE DRIVING 65 MPH, THE ENGINE STALLED AND THE ENGINE STABILITY POWER REDUCTION WARNING LIGHT ILLUMINATED. THE FAILURE RECURRED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE ACCELERATOR PEDAL AND RE-LEARNED IDLE FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. ALSO, WHILE DRIVING AT VARIOUS SPEEDS, THE GEAR SHIFT BECAME INOPERABLE. THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION WAS FAILING AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURES. THE FAILURE MILEAGE WAS APPROXIMATELY 44,815. UPDATED 01/12/16*LJ *CN *TR

WHEN YOUR AT A COMPLETE STOP VEHICLE GIVES A HARD JERK LIKE SOMEONE HAS REAR ENDED YOU. ALL OF THE IMPALA'S HAVE A FAILED TRANSMISSION PRESSURE CONTROL SOLENOID WHICH CAN CAUSE ACCIDENTS WHEN IT JERKS VERY HARD CAUSING SOMEONE TO RUN INTO THE BACK OF ANOTHER VEHICLE. NO CHECK ENGINE LIGHT OR ANYTHING WILL COME ON LETTING YOU KNOW THE PROBLEM. YEARS 2000 TO 2015 ALL HAVE THE SAME PROBLEM. NEEDS TO BE RECALLED BEFORE SOMEONE SERIOUSLY GETS INJURED.

TL* THE CONTACT OWNS A 2011 CHEVROLET IMPALA. WHILE DRIVING APPROXIMATELY 60, THE VEHICLE STALLED AFTER THE STABILITRAK, TRACTION CONTROL, AND ENGINE POWER DOWN WARNING INDICATORS ILLUMINATED. THE VEHICLE RESTARTED; HOWEVER, THE FAILURE RECURRED ON ONE OTHER OCCASION WHILE DRIVING APPROXIMATELY 45 MPH. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE ENGINE WIRING HARNESS WAS FAULTY AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 34,500.

THE VEHICLE IS ALWAYS SHAKING WHEN BRAKING THE VEHICLE MAKES WEIRD SOUNDS WHEN TURNING THE VEHICLE JERKS ALL THE TIME OR SOMETHING WHEN TRYING TO STEP ON THE GAS THE VEHICLE WON'T GO

THE CONTACT STATED THAT ALL THE WARNING INDICATORS ILLUMINATED AT THE TIME OF THE FAILURE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 100,000.

THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 83,679. MA 10/8 *CN

WE OWN BOTH A 2011 AND A 2013 CHEVY IMPALA. BOTH VEHICLES GRIND AND HESITATE. THEY BOTH ACT THIS WAY WHILE TAKING OFF FROM A LIGHT, BACKING OUT OF THE DRIVEWAY AND THEN PUTTING IT IN DRIVE AND ANY OTHER TIME IT FEELS NECESSARY TO DO SO. EXCEPT WHILE BEING CHECKED BY THE MECHANIC. WE OWNED A 2007 IMPALA THAT DID THE SAME THING. OUR REMEDY, PUSH THE TRACTION CONTROL BUTTON TO THE "OFF" POSITION. STOPPED MAKING THE NOISE AND NO LONGER HESITATES AFTER PUTTING IT IN DRIVE. OF COURSE, WE HAVE TO DO THIS EACH AND EVERY TIME WE GET IN THE CAR. NO MORE BUYING CHEVY'S FOR US.

WHEN THE ACCELERATOR PEDAL IS RELEASED, THE CAR DOES NOT SLOW DOWN. DEALER SAYS CAR IS OK. THIS HAPPENS AT ANY SPEED AND MAKES IT DIFFICULT TO SLOW DOWN OR STOP. THE CAR WILL RUN ALONG AT ABOUT 20 MILES PER HOUR FROM A STOPPED POSITION WITHOUT TOUCHING ACCELERATOR. VERY DIFFICULT TO DRIVE ON ICE OR SNOW.

WHILE DRIVING ON THE HIGHWAY THE "SERVICE TRACTION CONTROL" MESSAGE COMES ON, THEN, THE MESSAGES "SERVICE STABILITY TRAK" THEN "ENGINE POWER IS REDUCED". AND THEN THE CAR SHUTS DOWN I HAD TO QUICKLY PULL OVER ON THE SIDE OF THE ROAD. AFTER A FEW MINUTES THE CAR STARTS UP AND EVERYTHING IS FINE. THIS HAPPENED TWICE SINCE THEN. EVERY COUPLE MONTHS THE SENSOR LIGHTS WOULD COME ON WITH THE ABOVE MESSAGE-WITHOUT CAR SHUTTING DOWN. THE LIGHTS COME ON A LOT MORE OFTEN NOW-ALTHOUGH THE CAR DOES NOT SHUT DOWN, IT'S THE FEAR OF THE POSSIBILITY. WHEN GOOGLING THIS PROBLEM WITH THE CAR IT SOUNDS LIKE THIS IS A COMMON PROBLEM. I'M NOT SURE WHY THERE HASN'T BEEN A RECALL. I'M BRINGING IN MY CAR TOMORROW TO GET FIXED. HOWEVER, ITS UPSETTING THAT THERE SEEMS TO BE A PROBLEM WITH THE THROTTLE POSITION SENSOR, AND THERE WAS A RECALL ON A...

I WAS DRIVING ON A HIGHWAY GOING APPROXIMATELY 55 MPH, THE ENGINE LIGHT, STABILITY CONTROL LIGHT, AND REDUCED ENGINE POWER LIGHT CAME ON AT THE SAME TIME. WITHIN TWO (2) MINUTES OF THE DASH WARNING LIGHTS COMING ON, THE CAR COMPLETELY SHUT IT SELF OFF WHILE I WAS DRIVING IN THE LEFT LANE GOING 55 MPH. I LOST STEERING, HAD NO POWER, OR BRAKING. I THREW THE CAR IN NEUTRAL, IN AN ATTEMPT TO GET IT STARTED IT WHILE I WAS IN MOTION WITH NO POWER. THE IMPALA DIDN'T EVEN TRY TO TURN OVER. THE CAR WASN'T RESPONDING BECAUSE THE POWER STEERING / BRAKING WAS NOT RESPONDING. THE IMPALA WENT INTO "LIMP MODE" WITHOUT WARNING. I LET THE CAR COST FOR A WHILE UNTIL I COULD FIND A SAFE SPOT TO APPLY THE EMERGENCY BRAKE. I REALLY HAD TO MUSCLE THE STEERING WHEEL WITH SOME SIGNIFICANT FORCE TO GET IT...

2/17/2015 WAS THE SECOND EVENT. I WAS DRIVING APPROX- 65 MPH UP A MOUNTAIN WHEN MY ELECTRONIC DISPLAY PANEL SHOWED STABILITRACK/SERVICE TRACTION CONTROL/VEHICLE IN REDUCED POWER. AS THE POWER SUDDENLY REDUCED I LOST POWER STEERING CONTROL AND BRAKE FUNCTION. SINCE I WAS TRAVELING AT A UP HILL GRADE, I WAS BARELY ABLE TO JERK THE STEERING WHEEL ENOUGH TO ROLL ACROSS THE LANE OF TRAFFIC BESIDE ME TO THE SIDE OF THE ROAD. I WASN'T ABLE TO GET OUT OF THE ROAD COMPLETELY AND WAS ALMOST HIT BY A LOGGING TRUCK. AFTER REMOVING THE KEYS FROM THE IGNITION FOR A FEW MINUTES, I RESTARTED THE CAR WITHOUT ANY HESITATION. THE ENGINE LIGHT STILL REMAINS ON AT THIS TIME. I DID CONTACT ONSTAR AND HAVE THEM RUN A DIAGNOSTIC TEST WHICH REVEALED A PROBLEM WITH SUPPOSED FUEL SYSTEM. I HAVE NOT TAKEN IT TO A DEALERSHIP YET. AFTER SO MANY COMPLAINTS...

REDUCED ENGINE SIGNAL CAME ON SHORTLY AFTER SERVICE TRACTION, BRAKES, STEERING, CAME ON THEN CAR SHUT OFF NO POWER TO ANYTHING. BRAKES, STEERING NOTHING WORKED. PUT CAR IN NEUTRAL TO TRY A RESTART NOTHING. GOT CAR TO A COMPLETE STOP TOOK THE KEY OUT. THE DASH MADE A WEIRD NOISE ALMOST LIKE SOMETHING RESET. I PUT KEYS BACK IN TURNED THE KEY CAR STARTED NO PROBLEM ONLY THING THE CHECK ENGINE LIGHT WAS ON. TOOK VEHICLE HOME WENT BACK LATER THAT NIGHT. STARTED IT UP AND CHECK ENGINE LIGHT WAS OFF. THIS HAPPENS ALMOST ONCE AWEEK. 2ND ISSUE HEATER BLOWER GOING DOWN THE ROAD JUST SHUT OFF WEATHER -2 PLUS A WIND CHILL. HAD IT SERVICED THEY REPLACED A MODULE BLOWER RAN FINE FOR 4 DAYS, WEATHER ADVISORY WINDCHILL TEMP IS -10 45 MILES AWAY FROM HOME HEATER BLOWER NOT WORKING AGAIN. *TR

I TURNED MY CAR ON TO LET IT WARM UP AFTER WORK, THEN STARTED DRIVING HOME. THEN SOME LIGHTS POPPED ON. IT SAID SERVICE STABILITITRAK. IT SAID THAT IT WAS REDUCING ENGINE POWER. SERVICE CONTROL SOON. IT WAS VERY SCARY DRIVING HOME. THE CAR WOULD TAKE OFF BY ITSELF AND IT FELT LIKE IT WAS STALLING OUT. ITS A FAIRLY NEWER CAR 2011, I SHOULDN'T BE HAVING THESE ISSUES. *TR

WHILE DRIVING ALONG A CURVY RIVER ROAD MY CHECK ENGINE LIGHT , MY TRACTION CONTROL AND THE STABILIZE LIGHT CAME OUT. THEN THE ENGINE REDUCED POWER. BARELY MADE IT HOME. WAITED FOR A FEW MINUTES RESTATED THE CAR AND IT RAN NORMAL BUT STILL FEEL THE CAR HESITATE. EVERY TIME I DRIVE IT I WORRY THAT ITS CONING TO DO IT AGAIN. I LIVE IN THE PART OF THE COUNTY THAT GETS SNOW AND AM WORRIED ITS GOING TO HAPPEN DURING A STORM, THIS NEEDS TO BE ADDRESSED. *TR

DRIVING 2011 CHEVY IMPALA IN CITY TRAFFIC. SERVICE STABILITRAK, SERVICE TRACTION CONTROL, REDUCED ENGINE POWER WARNING MESSAGES RECEIVED. THIS HAS HAPPENED SEVERAL TIMES AT INTERMITTENT INTERVALS IN THE TWO YEARS I HAVE OWNED THE VEHICLE. IN SOME INSTANCES, THE ENGINE SHUTS OFF AND ALL POWER STEERING AND POWER BRAKING IS LOST MAKING IT VERY DIFFICULT TO CONTROL THE VEHICLE. AFTER RESEARCH, THIS IS A PROBLEM THAT GM NEEDS TO ADDRESS. I HAVE FOUND THAT IF I PULL OVER WHEN THE WARNING MESSAGES DISPLAY, SHUT THE CAR OFF, WAIT APPROX 10 MIN, THE CAR WILL START AGAIN, THE MESSAGES WILL BE GONE, AND THE CAR WILL DRIVE NORMALLY.

MY FAMILY AND I WERE TRAVELING FROM NEWARK, NJ FROM THE JULY 4TH HOLIDAY BACK HOME TO RALEIGH NC ON 95 SOUTH IN VIRGINIA AND GOING AT A SPEED OF 72MPH APPROX. AND THE CAR/ENGINE JUST TURNED OFF AT THAT RATE OF SPEED WITH 2 CHILDREN IN THE BACK SEAT OF THE VEHICLE. AFTER WE SAT ON THE SIDE OF THE ROAD FOR ABOUT 45MIN THE VEHICLE PROCEEDED TO START AND WE MADE IT HOME TO NC. THE FOLLOWING BUSINESS DAY AFTER THE HOLIDAY I TOOK IT TO MY MECHANIC GIAO AUTO LOCATED ON CAPITAL BLVD IN RALEIGH NC AND HE COULD NOT DETERMINE WHY THE VEHICLE SHUT OFF THE WAY IT DID. SO I CONTINUED TO DRIVE JUST WITH PRECAUTION. I RECEIVED A LETTER ON 8/21/2014 REGARDING THE RECALL AND WAS LIVID BECAUSE THIS HAS HAPPENED TO MY FAMILY WHILE DRIVING ON THE INTERSTATE!

THERE WERE NO WET NOR ROAD HAZARD CONDITIONS THAT WOULD HAVE CAUSED THIS TO HAPPEN. FURTHERMORE, I WAS DRIVING AT 60MPH WHEN THIS OCCURRED IN MODERATE TRAFFIC AND ALMOST GOT REAR ENDED. THIS IS A VERY UNSAFE ISSUE, AND I WAS TOLD THAT THE GAS PEDAL NEEDS TO BE REPLACED. SINCE THEN MY VEHICLE HAS DONE THIS SEVERAL TIMES. THIS ISSUES NEEDS TO BE RECALLED BECAUSE A LOT OF INDIVIDUALS HAVE COMPLAINED ABOUT HAVING THE SAME ISSUES WITH THE IMPALA. WHAT IS IT GOING TO TAKE AN INJURY OR FATALITY FOR A RECALL ON THESE VEHICLES. MOREOVER, ANY VEHICLE THAT SHUTS OFF WHILE DRIVING AT ANY...

PULLED INTO 35 MILE PER HOUR TRAFFIC AND LOST ENGINE POWER. WARNING LIGHTS AND MESSAGE FOR STABILTRAC, SERVICE TRACTION CONTROL AND REDUCED ENGINE POWER CAME ON.

I WAS DRIVING DOWN I-74 OUTSIDE PEORIA IL AND THE STABILITRAC POWER REDUCED POPPED UP ON THE DASH AND 3 SECONDS LATER IT STATED THE ANTI-THEFT ENGAGED AND SHUT MY CAR OFF. I ALMOST GOT REAR ENDED BY MULTIPLE CARS ON THE INTERSTATE. I WAS IN THE LEFT LANE AND BARELY MADE IT TO THE SIDE OF THE ROAD. I EMAILED GM AND THEY HAVE NOT GOTTEN BACK TO ME YET. I EMAILED THEM THE SAME DAY IT HAPPENED. *TR

THE SERVICE STABILITRAK, TRACTION CONTROL, AND REDUCED ENGINE POWER WARNINGS CAME ON AND THE CAR STARTED TO LOSE POWER GOING AROUND A CURVE. I TEMPORARILY LOST THE ABILITY TO ACCELERATE NEARLY CAUSING ME TO GET REAR ENDED BY A VEHICLE BEHIND ME. SINCE THE INCIDENT OCCURRED THE CAR HAS BEEN VERY SLUGGISH AND UNSAFE TO OPERATE. I AM PLANNING TO GET THIS SERVICED ASAP. AFTER READING MANY FORUM POSTS ONLINE REGARDING THIS SAFETY ISSUE, I BELIEVE A RECALL SHOULD BE ISSUED. I WAS SHOCKED TO SEE HOW RAMPANT OF A PROBLEM THIS AND THAT IT IS USUALLY CAUSED BY A FAULTY THROTTLE BODY THAT ISN'T COVERED IN THE 100K MILE POWERTRAIN WARRANTY. MYSELF AND MANY OTHERS FROM WHAT I HAVE READ BELIEVE THIS TO BE A VERY DANGEROUS MALFUNCTION. IF THIS WERE TO HAPPEN AT HIGH SPEEDS ON THE HIGHWAY SOMEONE COULD VERY EASILY BE KILLED IF THEIR CAR LOSES...

I WAS DRIVING AND SUDDENLY THE CAR LURCHED AND THE CHECK ENGINE LIGHT CAME ON AS WELL AS MESSAGES THAT SAID, "REDUCED ENGINE POWER, CHECK STABILITRAK AND SERVICE TRACTION CONTROL". I MADE IT HOME AND PARKED THE CAR IN THE DRIVEWAY FOR A DAY AND A HALF AND WHEN I STARTED IT AGAIN, THE MESSAGES WERE GONE BUT THE ENGINE LIGHT WAS STILL ON. I BROUGHT IT TO MY LOCAL DEALER AND WHEN THEY CHECKED IT, IT CAME UP STORED CODE P2122- ACCELERATOR PEDAL SENSOR. I HAVE HAD THIS CAR 6 MONTHS AND IT ONLY HAS 42426 MILES ON IT AND NOW I'VE HAD TO SPEND OVER $300 ON A REPAIR. IT IS RIDICULOUS THAT THIS SENSOR FAILED ALREADY. AFTER DOING SOME RESEARCH, I FOUND THAT THIS IS A COMMON PROBLEM WITH MANY PEOPLE EXPERIENCING THE SAME THING. GM SHOULD BE FORCED TO FIX THIS ISSUE AND REIMBURSE ALL OF...

IN MAY OF 2013 I RECEIVED A MESSAGE ON MY DASH BOARD ABOUT STABILI TRACK, TRACTION CONTROL AND REDUCED ENGINE SPEED. I TOOK MY CAR TO THE CHEVY DEALER SO I COULD GET A DIAGNOSTIC, AND THEY REPLACED A SENSOR BEHIND MY PEDAL. JUST THIS WEEKEND, SUNDAY APRIL 13, 2014. THE MESSAGE DISPLAYED ACROSS THE DASHBOARD AGAIN. I'M GOING TO CALL THE CHEVY DEALER THAT FIXED IT THE FIRST TIME. THEN I'M GOING TO CALL GM. THIS IS A VERY DANGEROUS MALFUNCTION IN THESE CARS. FROM VIEWING AND READING OTHER STORIES, THIS IS SOMETHING GM SHOULD HAVE KNOWN ABOUT AND ADDRESSED. *JS

I WAS DRIVING DOWN THE HIGHWAY ON THE HOMESTRETCH OF A ROADTRIP FROM PA TO FL WHEN THE "SERVICE STABILITRAK" , FOLLOWED BY "ENGINE POWER REDUCED" MESSAGE STARTED FLASHING. THE TWO LIGHTS ON THE DASHBOARD ALSO WENT OFF. SINCE I WAS IN THE MIDDLE OF THE HIGHWAY, I WAS UNABLE TO FIND A GOOD PLACE TO ADDRESS THE ISSUE, AND I FIGURED LIKE MOST TIMES THE "CHECK ENGINE" LIGHT GOES ON, THAT IT WAS SOMETHING THAT I COULD WAIT TO DEAL WITH WHEN I GOT HOME. I CONTINUED DRIVING FOR ABOUT 15 MINUTES AND THEN THE MESSAGE CHANGED AND SAID "DISABLING THROTTLE" OR SOMETHING TO THAT EFFECT, AND I FELT THE ENGINE LOSING POWER. I WAS IN THE MIDDLE LANE, DOING AROUND 55 MILES PER HOUR WITH CARS ALL AROUND ME. I IMMEDIATELY PUT ON MY FOUR-WAY FLASHERS AND FORTUNATELY PEOPLE IN THE RIGHT LANE SLOWED DOWN AND LET ME...

JULY 2013 HAD HUB BEARINGS REPLACED IN ORDER FOR CAR TO PASS INSPECTION. ISSUE WITH "SERVICE TRACTION CONTROL" HAD NEVER OCCURRED THE PRIOR WINTERS -- CAR SLOWS DOWN, ENGINE SLOWS DOWN -- THIS JUST STARTED HAPPENING AFTER THE HUB BEARINGS WERE REPLACED. ON MARCH 23, 2014, AFTER PAYING TOLLS ON THE TURNPIKE, THE "SERVICE TRACTION CONTROL" WARNING AGAIN APPEARED (NO SNOW, NOTHING TO TRIGGER THE WARNING) AND THEN MY CAR STOPPED, NO POWER...THE STEERING LOCKED...FORTUNATELY I WAS GOING SLOW ENOUGH AND SOMEHOW MADE IT TO THE BREAKDOWN LANE. CAR HAD ABSOLUTELY NO POWER...COMPLETELY DEAD. WAITED ABOUT 1/2 HOUR AND WAS ABLE TO RESTART. CALLED GM 3/25 WHO CONTACTED THE DEALER FOR AN APPOINTMENT FOR ME. DEALER NEVER CALLED ME (NOW 4/7/14). I HAVE PLACED ANOTHER CALL TO GM. THE VEHICLE SHOULD NOT COMPLETELY SHUT DOWN. ASKED GM IF THERE WAS A RECALL AND WAS TOLD NO. I HOPE OTHERS WHO...

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
