2011 Chevrolet Impala

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 TO TURN. I HAVE NEVER HAD ANY PROBLEMS WITH THIS VEHICLE BEFORE THIS ISSUE. IT TURNS OUT THAT THE "PEDALASSEMBLY" GAS PEDAL SENSOR WENT BAD, CAUSING THE 2011 IMPALA TO GO INTO "LIMP MODE" WHILE I WAS DRIVING. *TR

TL*THE CONTACT OWNS A 2011 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING APPROXIMATELY 60 MPH, THE ACCELERATOR PEDAL BECAME STUCK WHEN DEPRESSED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC, WHERE IT WAS DIAGNOSED THAT THE ACCELERATOR PEDAL NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 65,000. THE VIN WAS NOT AVAILABLE.

MY WIFE WAS DRIVING HOME FROM WORK GOING 65 DOWN A VERY BUSY HIGHWAY. ALL OF A SUDDEN THE REDUCED ENGINE POWER LIGHT, CHECK ENGINE, STABILITY CONTROL OFF, AND TRACTION CONTROL LIGHTS CAME ON. THE CAR BEGIN TO LOOSE SPEED. LUCKILY SHE WAS ABLE TO GET OVER TO THE RIGHT SHOULDER WITHOUT ANYONE HITTING HER. WHEN SHE GOT TO THE SHOULDER THE CAR WAS RUNNING REALLY ROUGH. SHE TURNED IT OFF WAITED A FEW MINUTES AND RESTARTED IT. IT THEN RAN FINE BUT THE CHECK ENGINE LIGHT REMAINED ON. SHE MADE IT HOME AND WAS SCARED TO DRIVE IT AGAIN. I TOOK IT TO WORK LAST NIGHT AND MADE IT ABOUT HALFWAY TO WORK AND IT DID THE EXACT SAME THING EXCEPT I WAS ABLE TO GET IT TO MAINTAIN 45MPH. WHEN I CAME TO A TRAFFIC LIGHT THOUGH THE ENGINE WAS RUNNING SO ROUGH THE CAR WAS VERY HARD TO STOP. I MADE IT TO WORK. WHEN I CAME OUT TO GO HOME THE FIRST STOP LIGHT I CAME TO IT STARTED ACTING UP AGAIN. FROM THE LIGHT I WAS BARELY ABLE TO GET IT TO GO 25MPH. I PULLED OVER AND SHUT THE CAR OFF WAITED A FEW MINUTES AND RESTARTED. EVERYTHING WAS FINE AGAIN. I MADE IT ABOUT 5 MILES AND ALL THE LIGHTS CAME ON AGAIN BUT I WAS ABLE TO MAINTAIN 45MPH IN THE 55MPH ZONE I WAS IN. I TOOK IT TO MY REPAIR SHOP AND THEY SAID IT NEEDS A THROTTLE BODY. THEY ALSO SAID GM HAS HAD ALLOT OF ISSUES WITH THESE. I CALLED MY GM DEALER TO SEE IF IT WOULD BE COVERED UNDER 5 YEAR 100K MILE WARRANTY AND THEY SAID THAT IT ISN'T. IF THERE HASN'T BEEN AN ACCIDENT CAUSED BY ONE OF THESE THROTTLE BODY ISSUES YET I WOULD BE SURPRISED. IT'S VERY DANGEROUS IN HEAVY TRAFFIC AND ALL OF A SUDDEN YOU CAN'T GO. *TR

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 ON VARIOUS SITES THAT I HAVE REVIEWED, LOOKS LIKE GM WOULD DO A RECALL AND INVESTIGATE THE PROBLEM BEFORE SOMEONE LOSES THEIR LIFE. *TR

DRIVING AT APPROX 35 MPH, MY CAR SHOWED SERVICE STABILITRACK / SERVICE TRACTION CONTROL / VEHICLE IN REDUCED POWER. I DID HAVE REDUCED POWER, COULD NOT GO ANY FASTER THAN 15 OR 20 MPH. I CONTINUED DOWN THE ROAD ANOTHER BLOCK AND WITHOUT WARNING, THE CAR SHUTS DOWN WHILE GOING DOWN A SLIGHT GRADE,, WHICH CAUSE STEERING TO BECOME VERY HARD TO USE ALONG WITH LITTLE TO NO BRAKING, I ENDED UP GOING THRU A STOP SIGN AT THE BOTTOM OF THE GRADE BECAUSE OF LACK OF BRAKING POWER, LUCKILY NO VEHICLES WERE COMING, I GOT THE VEHICLE STOPPED, AND LOOKED AT THE DISPLAY, IT SAID IGNITION DISABLED, SERVICE THROTTLE. BY THE VEHICLE SHUTTING DOWN THAT IS A SAFETY ISSUE, THE VEHICLE SHOULD NEVER SHUT DOWN MAKING STEERING AND BRAKING ALMOST IMPOSSIBLE, IF IT FINDS AN ISSUE WITH THE THROTTLE, IT SHOULD JUST DISABLE THE THROTTLE SO I CAN STEER AND BRAKE WITHOUT PROBLEM. AFTER ATTEMPTING TO START THE VEHICLE A FEW TIMES WITHOUT SUCCESS, THE 4TH TIME I TRIED THE VEHICLE DID START BACK UP AND WAS ABLE TO CONTINUE TO WORK, BUT WAS DID NOT SEEM TO BE RUNNING RIGHT AND CHECK ENGINE LIGHT STAYED ON. *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
