2010 Chevrolet Impala

WHEN THERE IS ANY MOVEMENT TO THE CAR BEFORE STARTING THERE IS A KNOCKING THAT SOUNDS LIKE IT IS COMING FROM THE AIR VENT ON THE PASSENGER SIDE; POSSIBLE ACTUATOR DOOR ?? ALSO, WHEN SWITCHING BETWEEN FRESH AND RECIRCULATED AIR THE KNOCKING STARTS AND LASTS 1 - 2 MINUTES. THE NOISE IS GETTING LOUDER AND I HAVE NOTICED THAT WHEN THE TEMPERATURE DROPS BELOW 36 DEGREES THE WINDOWS FOG COMPLETELY AND RUNNING THE DEFROSTER AT IT'S MAXIMUM SPEED WILL NOT CLEAR THE WINDOWS. I HAVE TO WIPE THE EXCESS CONDENSATION WITH A TOWEL TO MAINTAIN VISIBILITY. MAY HAVE TO DO WITH THE ACTUATOR DOOR BEING STUCK AND INTERFERES WITH THE DEFROSTER?? I HAVE TRIED USING RAIN-X ANTI-FOG WIPES TO NO AVAIL. NEED SOME HELP GM. *TR

THE CONTACT STATED THAT THE CHECK ENGINE, ENGINE POWER REDUCED, SERVICE STABILITRAK, TRACTION CONTROL, AND THE ENGINE OVERHEATED WARNING LIGHTS ILLUMINATED . THE VEHICLE WAS TAKEN TO A DEALER WHERE IT WAS DIAGNOSED THAT THE SECONDARY AIR INJECTION VALVE, THE SECONDARY AIR PUMP, AND THE APP SENSOR FAULT NEEDED TO BE REPLACED.

THE APPROXIMATE FAILURE MILEAGE WAS 44,000 AND THE CURRENT MILEAGE WAS 80,000....UPDATED 07/15/14 *BF

WHILE DRIVING AT 30 MPH THE TRAK STABILIZATION LIGHT CAME ON WITH A WARNING THAT ENGINE POWER WAS REDUCED. I STOPPED THE CAR AND SHUT OFF FOR ABOUT 5 MINUTES. WHEN I RESTARTED THE CAR, THE WARNINGS CAME BACK ON AGAIN. I WAS ABLE TO MAKE IT TO MY DESTINATION SAFELY. WHEN I GOT BACK IN THE CAR APPROXIMATELY 6 HOURS LATER, THE CAR STARTED FINE WITH THE ONLY WARNING BEING THE CHECK ENGINE LIGHT. I DROVE HOME AND CALLED MY LOCAL REPAIR TO LOOK AT IT. THE NEXT DAY WHEN I STARTED IT THERE WERE NO WARNING LIGHTS AT ALL AND MY LOCAL DEALER CHECK THE SENSORS AND COULD NOT FIND ANYTHING WRONG. THIS HAPPENED AGAIN ABOUT 30 DAYS LATER AND HAS CONTINUED TO HAPPEN 4 TIMES SINCE THEN. EACH TIME AFTER 2-5 HOURS THE CAR SEEMS FINE EXCEPT FOR CHECK ENGINE LIGHT WHICH GOES OUT THE NEXT DAY. *JS

WHILE DRIVING NORTHBOUND ON I-75 IN SOUTHERN KY, THE CAR SUDDENLY LURCHED A LITTLE AND "TRACTION CONTROL" AND "STABILIZATION" ERRORS DISPLAYED FOLLOWED BY "REDUCING POWER." AND, THE CHECK ENGINE LIGHT CAME ON. I CALLED MY CHEVY DEALER AND ASKED IF IT WAS SAFE TO CONTINUE DRIVING - THEY SAID YES, AS LONG AS THE CHECK ENGINE LIGHT WASN'T FLASHING. WE WENT ABOUT 5 - 10 MORE MILES AND THE DISPLAY FLASHED SOMETHING ABOUT THROTTLE PROBLEM AND THEN "SHUTTING DOWN ENGINE", WHICH IT DID IMMEDIATELY WITH NO WARNING WHILE WE WERE DOING ABOUT 70 - 75MPH IN THE MIDDLE OF THE 3 NORTHBOUND LANES OF I-75. I HAD TO TRY TO STEER TO THE SHOULDER WITH NO POWER STEERING OR BRAKES. ONCE THERE, I TRIED TO RESTART THE CAR AND NOTHING HAPPENED - IT DISPLAYED "STARTER DISABLED." WE CALLED OUR ROAD SERVICE AND THEY TOOK OUR INFO, FOUND THE NEAREST CHEVY DEALER WHO SAID THEY COULD WORK ON IT ASAP IF WE GOT IT IN THERE. WHILE THEY WERE WORKING ON SETTING UP A TOW I TRIED STARTING IT AGAIN. IT STARTED BUT THE CHECK ENGINE WAS STILL ON. I TRIED DRIVING A LITTLE ALONG THE SHOULDER AND IT SEEMED OK SO I SAID WE'D TRY DRIVING TO THE DEALER RATHER THAN WAIT FOR A TOW TRUCK. WE MADE IT. THEY GOT ON IT FAIRLY QUICKLY AND FOUND THE PROBLEM WAS THE GAS PEDAL POSITION SENSOR. WE WERE FORTUNATE THAT THE TRAFFIC WAS LIGHT AND I COULD SAFELY PULL OFF. I HATE TO THINK WHAT THE RESULTS WOULD HAVE BEEN IF THIS HAD HAPPENED EARLIER AS WE WERE TRAVELING THRU ATLANTA WITH ITS 6 LANES OF HEAVY TRAFFIC. SUDDENLY LOSING POWER AND CONTROL IN THAT TRAFFIC WOULD PROBABLY HAVE CAUSED ONE OF THOSE MULTI-VEHICLE ACCIDENTS THAT MAKE THE NATIONAL NEWS. WHAT KIND OF INCOMPETENT PROGRAMMING OF THE CAR'S COMPUTER WOULD TRIGGER A FULL, INSTANT SHUTDOWN BECAUSE OF A FAULTY ACCELERATOR PEDAL POSITION SENSOR? I WOULD SUGGEST AN IMMEDIATE RECALL TO RE-FLASH THE COMPUTER TO ELIMINATE THE NO-WARNING SHUT DOWN. *TR

WHEN THE INCIDENT FIRST OCCURRED, THE ENGINE LIGHT CAME ON AND THE DASH READ "SERVICE STABILITRAK", "SERVICE TRACTION CONTROL" AND "ENGINE POWER REDUCED". IT SEEMED FINE WHEN I TURNED OFF THE CAR AND TURNED IT BACK ON. THE NEXT INCIDENT DIDN'T HAPPEN UNTIL A WHILE LATER, AND THEN IT WASN'T THAT BAD. A FEW MONTHS LATER, I WAS DRIVING BACK ON THE HIGHWAY AND THE SAME THING HAPPENED, EXCEPT IT SAID "STARTING DISABLED, SERVICE THROTTLE" AND THE CAR SHUT OFF. I PULLED OVER TO THE SIDE AND I WAS ABLE TO RESTART THE CAR AFTER WAITING A FEW MINUTES. IT WAS A SCARY EXPERIENCE. EVENTUALLY, LEADING UP TO TODAY, MY CAR GOT WORSE AND WORSE, AND EVENTUALLY IT JUST STARTED TURNING OFF AT STOPLIGHTS WITH THE MESSAGE "STARTING DISABLED, SERVICE THROTTLE". IT STARTS WITH THE OTHER MESSAGES ALMOST AS SOON AS I TURN ON THE CAR. THE ENGINE REVS AND THE CAR SOUNDS AWFUL. *TR

WHILE DRIVING DOWN I 80 WEST OF PRINCETON ILL THE CHECK ENGINE LIGHT CAME ON FOLLOWED BY THE CHECK TRACTION CONTROL LIGHT .THE DASH THEN LIGHT UP LIKE A CHRISTMAS TREE WITH LIGHTS I HAD NEVER SEEN AND CAN NOT DUPLICATE WITH TURNING THE KEY TO ON .THE CAR IMMEDIATELY DIED AND I LOST POWER STEERING AND BRAKES .I GOT THE CAR STOPPED SAFELY .I CALLED A MECHANIC IN THE TOWN I LIVE IN AND HE ASKED IF IT WOULD START AGAIN. EARLIER WHEN I TRIED TO START IT ACTED AS THOUGH THE BATTERY WAS DEAD. THIS TIME IT STARTED AND I DROVE IT HOME .A LOCAL REPAIR SHOP REPLACED THE GAS PEDAL .I HAD BOUGHT THIS CAR NEW AND IT HAS NEVER BEEN IN A CRASH OR HAD ANY REPAIRS DONE BESIDES ROUTINE SERVICE. NO ONE WAS HURT BUT THIS CAR SHOULD NOT HAVE SHUT OFF AT 70 MPH BECAUSE OF A DEFECTIVE SENSOR ON A GAS PEDAL.I AM A RETIRED STATE TROOPER AND I AM SURE MY TRAINING SAVED ME FROM BEING IN AN ACCIDENT YESTERDAY BECAUSE I HAPPENED TO HAVE OTHER CARS AND SEMI S DRIVING NEAR ME. *TR
