2009 Chevrolet Impala

DRIVING ON INTERSTATE VEHICLE SUDDENLY LOST ALL POWER AND WOULD NOT ACCELERATE & QUICKLY DECELERATED WITH ANY PRIOR WARNING. 18 WHEELER ALMOST REAR ENDED ME. INSTRUMENT PANEL DISPLAYED, ENGINE POWER REDUCED,SERVICE TRACTION CONTROL, SERVICE STABILITRAK, AND CHECK ENGINE LIGHT. FINALLY EXITED INTERSTATE SAFELY AND SHUT DOWN ENGINE THINKING IT WAS GOING TO BLOW UP AND AFTER 2-3 TRIES TO RESTART MESSAGES DISAPPEARED AND VEHICLE SEEMED TO BE OK. TOOK VEHICLE TO MECHANIC & FOUND CODES EVIDENCING THE LOSS OF COMMUNICATION BETWEEN THE TAC AND OR THE APP UNITS CAUSING VEHICLE TO GO INTO LIMP MODE BUT COULD NOT GET THE CONDITION TO REOCCUR. MECHANIC HAD TO REMOVE CODES TO PERMIT TO DUPLICATE PROBLEM, COULD NOT DUPLICATE AND TOLD ME TO WAIT UNTIL RECURRED. WHILE LOOKING FOR REPAIR SHOP WAS SCARED IT WOULD HAPPEN AGAIN RECEIVED LETTER FROM GM STATING IF THE ABOVE CONDITION HAD OCCURRED THEY WOULD FIX. CALLED GM DEALER MENTIONED LETTER THEY REFUSED TO REPAIR UNLESS THE MESSAGES WERE PRESENT ON PANEL, REFUSED TO LOOK AT THE VEHICLE. CALLED GM CUSTOMER SERVICE REFERENCING LETTER, EXPLAINED GM DEALER REFUSED TO REPAIR. WAS TOLD BY ANGELA ISSUE WAS SAFETY RELATED PROBLEM BUT GM WOULD NOT ADMIT TO SAFETY ISSUE. GM AGREED TO PAY FOR ONE HOUR OF DIAGNOSTIC TIME TO DETERMINE IF VEHICLE QUALIFIED FOR REPAIR, DEALER WAS UNABLE TO DUPLICATE PROBLEM, REFUSED TO REPAIR. CALLED GM AND WAS TOLD NO REPAIR WOULD BE MADE EVEN THOUGH THE PROBLEM HAD OCCURRED AS STATED IN THE LETTER AND TO WAIT UNTIL SITUATION OCCURRED AGAIN THEN NOT TO START ENGINE AND TOW TO GM DEALER. WAS TOLD GM WOULD NOT PAY FOR TOW OR INCONVENIENCE AND IF THEY COULD SEE CODES THEY MIGHT REPAIR PROBLEM. THIS IS DEFINITELY A SAFETY ISSUE SINCE WHEN THIS OCCURS THE VEHICLE LOSES ALL POWER AND BASICALLY SHUTS DOWN AND WILL NOT ACCELERATE BEYOND 5 MPH IF AT ALL.

I BOUGHT THIS CAR USED IN 2012. THIS CAR HAD PERIODIC ELECTRICAL ISSUES AND A CO2 SENSOR FAILURE, BUT THERE WERE NO ISSUES COMPARABLE TO A TOTAL TRANSMISSION FAILURE. EARLIER IN THE WINTER OF 2015, I NOTICED THAT THE TRANSMISSION WOULD NOT SHIFT UP INTO FOURTH GEAR ON THE FREEWAY UNTIL AFTER TEN MINUTES OF DRIVING. ONE DAY IN ANN ARBOR, MI, I WAS ACCELERATING OUT OF A TURN WHEN THE RPM METER STARTED REVVING TO 6,000 AND THE ENGINE LOST POWER. AFTER RESTARTING THE IMPALA, THE CAR WENT A FEW HUNDRED FEET TO RED LIGHT AND DIED AT THE INTERSECTION. I EVENTUALLY WAS ABLE TO DROP THIS VEHICLE OFF AT AN AUTOMOTIVE REPAIR SHOP FOLLOWING A LONG TRIP FULL OF TRANSMISSION FAILURES AND START-UPS. THE MECHANIC LATER STATED THAT THE TRANSMISSION WOULD NEED TO BE REBUILT. THE REPAIR COST WAS OVER $1,600 AND THE TRANSMISSION STILL POSSESSES THE SAME PROBLEMS THAT EXISTED PRIOR TO THIS EVENT.

WHILE DRIVING ONTO A HIGHWAY WHEN I REACH 56 MILES PER HOUR MY VEHICLE LOST POWER AND SLOW DOWN THE BRAKES LOCKED AND THE ELECTRICAL SYSTEM WENT HAYWIRE. THE LOCKS STARTED LOCKING AND UNLOCKING WHILE THE VEHICLE WAS IN MOTION. THE LIGHTS STARTED FLICKERING ON AND OFF AND THE CAR STARTED SHAKING RAPIDLY AND THE BRAKES LOCKED UP. ONCE I STARTED THE VEHICLE BACK UP AND THE IGNITION SWITCH SEEMED TO BE STUCK AND THE AIR BAG LIGHT DISPLAYED ON THE DASHBOARD. WHEN I TURN OFF THE VEHICLE AND TRY TO REMOVE THE KEY THE KEY WILL NOT COME OUT SO I HAVE TO PUT IT INTO NEUTRAL AND BACK INTO PARK A FEW TIMES BEFORE IT WILL RELEASE THE KEY. SINCE THIS HAS OCCURRED I HEAR A KNOCKING SOUND IN MY GLOVE BOX WHEN THE DOOR IS OPEN AND CLOSED AND SOMETIME HOURS AFTER ILL HEAR THE NOISE AND THE ELECTRIC WILL FLICKER. *TR

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE AT A COMPLETE STOP, THE TRANSMISSION WOULD GO INTO A HARD TRANSITION OF GEARS VERY SLOWLY BEFORE SHIFTING INTO A NORMAL GEAR. THE VEHICLE WAS TAKEN TO A DEALER. THE TECHNICIAN WAS NOT ABLE TO DUPLICATE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 85,000.

I HAVE BEEN HAVING THE SERVICE ENGINE LIGHT COME INTERMITTENTLY ALONG WITH THE SERVICE TRACTION CONTROL LIGHT. I HAVE HAD A TECHNICIAN LOOK AT THIS FOR ME AND ADVISED THAT THE THROTTLE CONTROL SENSOR (ACCELERATOR PEDAL) IS GOING IN AND OUT. THE ACCELERATOR PEDAL IS CONNECTED TO A SENSOR THAT DRIVES THE THROTTLE ON THE ENGINE. WHEN THIS HAPPENS INTERMITTENTLY THE VEHICLE LOOSES ENGINE POWER AND TRACTION CONTROL. *TR

DRIVING TO WORK AND THE SERVICE TRACTION CONTROL LIGHT WENT ON THEN ENGINE POWER REDUCED AND THROTTLE ERROR AND THE CAR WOULD NOT ACCELERATE AND POWERED DOWN. I WAS AT RED LIGHT SO I TURNED THE CAR OFF AND TURNED IT BACK ON THE CAR WOULD NOT ACCELERATE SO I TURNED IT OFF AGAIN AND WAITING PUT MY FLASHERS ON, WAITED A FEW MORE MINUTES AND THE CAR FINALLY STARTED TO MOVE. I TOOK TO THE DEALERSHIP BECAUSE IT'S A POWERTRAIN ISSUE AND I HAVE 100K POWERTRAIN WARRANTY AND THE DEALERSHIP SAID IT'S NOT POWERTRAIN AND WANTED $778 TO REPAIR, I CALLED CHEVY AFTER SEEING THE FORUMS ONLY THIS IS A KNOWN ISSUE THOUSANDS OF PEOPLE WITH THE SAME COMPLAINT AND CHEVY SAID THEY ARE GOING TO WORK WITH THE DEALERSHIP. I HAVE TO BE BACK AT WORK MONDAY AND DRIVE THROUGH A VERY ROUGH NEIGHBORHOOD I DO NOT WANT TO BREAKDOWN IN THAT NEIGHBORHOOD. *TR
