2009 Chevrolet Impala Engine Problems

It rumbles when I start my car

Transmission

The contact owns a 2009 Chevrolet Impala. The contact stated that upon purchasing the vehicle from an independent mechanic, the check engine warning light was illuminated. The mechanic informed her that the vehicle was included in an unknown recall. The independent mechanic took the vehicle to the dealer for the recall repair. A month after the repair, the check engine warning light reappeared. The dealer nor the manufacturer had yet to be notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 156,000.

THIS HAS BEEN HAPPENING FOR SEVERAL YEARS, AND HAPPENED AGAIN YESTERDAY..... PULLED OUT ONTO 4 LANE DIVIDED HIGHWAY AND TRACTION CONTROL LIGHT CAME ON, DASH SAID "ENGINE POWER REDUCED", BUT DID NOT SEEM TO BE SIGNIFICANTLY LOW ON POWER. DROVE ABOUT 5 MILES DOWN THE ROAD, THEN CAR SUDDENLY DIED. WAS ABLE TO PULL OVER TO SIDE OF THE ROAD (WITH THREE SMALL CHILDREN IN THE VEHICLE), TRIED TO RESTART THE CAR BUT DISPLAY SAID "STARTING DISABLED, SERVICE THROTTLE". WAITED ABOUT 5 MINUTES AND CAR RESTARTED. WAS ABLE TO DRIVE HOME, NO REDUCED POWER BUT CHECK ENGINE LIGHT REMAINED ON. I HAVE SEEN MANY COMMENTS ONLINE FROM OTHERS WHO OWN SIMILAR GM VEHICLES THAT HAVE HAD SIMILAR ISSUES. WE HAVE ALSO HAD SIMILAR ISSUES WITH OUR 2011 SUBURBAN, ALTHOUGH NO STALLING. THERE SHOULD BE AN IMMEDIATE RECALL FOR ALL 2008 - 2011 GM VEHICLES TO REPAIR THIS ISSUE, MOST LIKELY ACCELERATOR PEDAL POSITION SENSOR.

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT STATED THAT SEVERAL WARNING INDICATORS ILLUMINATED, INCLUDING THE ABS, AIR BAG, SERVICE TRACTION CONTROL, AND STABILITY CONTROL. THE CONTACT ALSO HEARD BANGING NOISES COMING ROM THE REAR OF THE VEHICLE, RESULTING IN ROUGH DRIVING. THE MANUFACTURER WAS NOTIFIED AND ADVISED THE CONTACT TO TAKE THE VEHICLE TO A DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE FAILURE MILEAGE WAS UNKNOWN.

EARLIER THIS YEAR MY CAR STARTED FLASHING A "REDUCE ENGINE POWER" AND "SERVICE TRACTION CONTROL" TOGETHER. MY CAR SOUNDED LIKE IT WAS WORKING HARDER TOO BUT I WAS CITY DRIVING LESS THAN 30MPH SO I DIDN'T OTHERWISE NOTICE PROBLEMS. THIS HAPPENED RARELY. A FEW MONTHS LATER I WAS ON THE FREEWAY JUST GETTING ON (FLAT ROAD) AND THE WARNINGS CAME ON SUDDENLY. THEN AS I GOT OVER 40MPH, MY CAR ENGINE SHUT DOWN AND MY STEERING WHEEL LOCKED. LUCKILY I WAS ABLE TO MAKE A SLIGHT TURN OFF MY WHEELS ENOUGH TO GET TO THE SIDE OF THE ROAD. MY CAR FLASHES THESE RANDOMLY AFTER RANDOM LENGTHS OF TIME OF THE CAR BEING ON AND DRIVEN AND IT'S ALMOST A DAILY OCCURRENCE. I'VE SEEN ONLINE NO ONE HAS BEEN ABLE TO SOLVE THE ISSUE.

CAR DRIVES FOR 15 MINUTES THEN DISPLAY AN "ENGINE POWER REDUCED" AND "SERVICE TRACTION CONTROL" LIGHT. CAR HESITATES TO ACCELERATE THE EVENTUALLY CUTS OFF AFTER A "SERVICE THROTTLE BODY LIGHT" COMES ON. CAR CUT OFF ON THE HIGHWAY AT 70MPH. WHENEVER THERE IS A PROBLEM WITH THE CAR THESE LIGHTS COME ON. IT DOESN'T SPECIFY WHAT THE ACTUAL PROBLEM IS.

BAD SOLENOID IN TRANSMISSION CAUSES CAR TO JERK UPON ACCELERATION. TRANSMISSION SLIPS. USUALLY HAPPENS TAKING OFF FROM A STOP WITH A SLOW ACCELERATION. FEELS LIKE BEING REAR ENDED AND CAN CAUSE SLUGGISH ACCELERATION. PROBLEM NEEDS TO BE ADDRESSED WITH A RECALL AS MANY OTHER IMPALA DRIVERS HAVE EXPERIENCED THIS SAME ISSUE. ISSUE HAS HAPPENED AT LEAST 9 TIMES WITHIN A 6 WEEK PERIOD.

"LOW OIL PRESSURE LIGHT, SHUT OFF ENGINE" KEEPS COMING ON. OIL IS FULL. SO FAR I HAVE AIR BAG LIGHT, TRACTION CONTROL LIGHT, ENGINE LIGHT, ENGINE SPEED REDUCED LIGHT ALL ON! HOW ARE THESE AUTO'S NOT BEING RECALLED! I WILL NEVER OWN A CHEVY AGAIN! UNSAFE PIECE'S OF JUNK!

MY TRACTION LIGHT COMES ON . WITH MY CHECK ENGINE LIGHT THEN MY POWER IS REDUED LIGHT COMES ON AT SAME TIME CAR HAS NO POWER CANT HARDLY GET IT TO MOVE CANT ACCELERATE TO GET OUT OF WAY OF CARS. LIGHT IS COMING AND GOING STAY ON FOR A WHILE GO OFF THEN COME BACK IN DAY OR SO

DISPLAYS "REDUCED ENGINE POWER" ON THE DASHBOARD AND THE ENGINE LIGHT IS ON

MY CAR'S ENGINE POWER WAS SEVERELY REDUCED SUDDENLY WHEN I WAS DRIVING ON INTERSTATE HIGHWAY 275 NORTH IN TAMPA, FL. A MESSAGE SHOWED ON THE DASH: " REDUCED ENGINE POWER, SERVICE TRACTION CONTROL" AND THE CHECK ENGINE LIGHT WAS ON. THIS HAPPENED TODAY AROUND 7 PM ON OCT 30, 2016. MY CAR IS A CHEVY IMPALA 2009. I SEARCHED ONLINE AND FOUND THOUSANDS OF MESSAGES ABOUT THE SAME ERROR MESSAGE OF REDUCED ENGINE POWER ON MANY MODELS OF GM CARS INCLUDING IMPALA, MALIBU, TRAILBLAZER, SILVERADO. THIS WORRIES ME VERY MUCH AS SO MANY SAME ERROR MESSAGES AND ENGINE PROBLEMS HAPPENED ON SO MANY GM CARS. MY RESEARCH SHOWS THAT GM HAS DONE NOTHING TO RESOLVE THIS PROBLEM YET. SO THIS IRRESPONSIBILITY OF GM ON THIS SPECIFIC ISSUE PUT THE LIVES OF HUNDREDS OF THOUSANDS OF DRIVERS IN DANGER. I HOPE NHTSA LOOKS INTO THIS PROBLEM AND PRESSURE GM TO ISSUE A RECALL IF POSSIBLE TO TAKE CARE OF THIS SERIOUS PROBLEM. THANK YOU! *TR

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE "SERVICE TRACTION CONTROL MODULE: ENGINE POWER REDUCED BY 50%" WARNING MESSAGE DISPLAYED. THE CONTACT STATED THAT THE VEHICLE STALLED WITHOUT WARNING ON SEVERAL OCCASIONS. MONTGOMERY CHEVROLET OF LOUISVILLE, KENTUCKY WAS MADE AWARE OF THE FAILURE AND STATED THAT THERE WAS NO RECALL AND THAT THERE WOULD BE NO SERVICE PROVIDED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 125,000.

REDUCED ENGINE POWER APPEARED FOLLOWED BY CHECK TRACTION CONTROL. THEN SYMBOL FOR CHECK TRACTION CONTROL AND ENGINE COMPLETELY IN PASSING LANE ON INTERSTATE 80. CHECK ENGINE SYMBOL ALSO LIT, CAR COMPLETELY DIED AND WOULD NOT RESTART. APPROX 15 MIN LATER, IT DID START WITH CHECK ENGINE SYMBOL LIGHTED.

I WAS WAITING AT A STOP LIGHT. WHEN THE SIGNAL TURNED GREEN, I TURNED AND AS I WAS TURNING MY CAR BEGAN TO DECELERATE AND SHUT DOWN. I HAD TO STEER HARD TO PULL OVER TO GET OUT OF TRAFFIC. I PULLED ALONGSIDE THE ROAD. THINKING MAYBE IT WAS LOW ON FUEL, I HAD MY BROTHER GET GAS AND WE PUT GAS IN IT. HOWEVER, IT WOULD NOT START. SAT FOR MAYBE 20 MINUTES TO SEE IF IT. NOTHING HAPPENED. MY SISTER CAME TO GIVE ME A JUMP THINKING THAT I NEEDED ONE. HOWEVER, NO LUCK AT ALL. HAD TO PULL THE CAR HOME. THE MECHANIC THOUGHT THAT IT WAS MY STARTER, PUT THE STARTER ON AND STILL NOTHING. THE END RESULT, MY ENGINE HAS SEIZED ON ME!!

TL* THE CONTACT OWNS A 2009 CHEVROLET IMPALA. WHILE DRIVING 65 MPH, THE ENGINE WARNING LIGHT ILLUMINATED AND RECURRED MULTIPLE TIMES BEFORE THE VEHICLE STALLED. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THE TECHNICIAN DIAGNOSED THAT THE ENGINE FAILED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE VEHICLE WAS REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 76,000.

THE CAR STATES SERVICE TRACTION CONTROL-ENGINE POWER IS REDUCED. WHILE DRIVING THE HIGHWAY THE CAR COMPLETELY SHUT OFF AND HAD TO WAIT ABOUT 10 MINUTES BEFORE BEING ABLE TO START IT AGAIN. I DRIVE HIGHWAY DAILY AND HAVE A (XXX) YEAR OLD SON THAT RIDES WITH ME THIS IS A SAFETY HAZARD FOR THE BOTH OF US. *TRPARTS OF THIS DOCUMENT HAVE BEEN REDACTED TO PROTECT PERSONALLY IDENTIFIABLE INFORMATION PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

I WAS JUST GETTING OFF OF WORK AND ON MY WAY TO GRAB SOMETHING TO EAT. AS I BEGAN TO MAKE A LEFT AT A TRAFFIC LIGHT THE SERVICE TRACTION AND REDUCED ENGINE SPEED LIGHT CAME ON. I COULD NOT GO MORE THAT 30 MPH AND IT BEGAN JERKING SO MUCH THAT I THOUGHT THE CAR WAS GOING TO SHUT OFF. I HAVEN'T DRIVEN IT SINCE BECAUSE I STILL HAVE TO FIT IT. THIS IS MY ONLY TRANSPORTATION AND IF I WAS ON THE FREEWAY IT COULD HAVE BEEN A HUGE ACCIDENT BECAUSE THE CAR JUST DROPPED IN SPEED WITH NO WARNING. I'VE SEEN THAT A LOT OF PEOPLE HAVE THIS ISSUE. IS GM LOOKING INTO THIS. THIS IS SOMETHING THEY SHOULD FIX WITH NO CHARGE ESP IF ITS HAPPENING TO A LOT OF PEOPLE. *TR

I OWN A 2009 CHEVROLET IMPALA. I WAS DRIVING ON THE HIGHWAY AT 65 MPH WHEN THE CHECK ENGINE LIGHT, TRACTION CONTROL LIGHT AND ENGINE POWER REDUCED LIGHT CAME ON. A FEW MINUTES LATER, IN HEAVY TRAFFIC IT SAID ENGINE SHUTTING DOWN AND THERE WAS A SHORT COUNTDOWN DISPLAYED BEFORE THE ENGINE DIED COMPLETELY. THIS IS VERY DANGEROUS AND I AM LUCKY TO HAVE BEEN ABLE TO GET OVER TO THE SHOULDER WITHOUT GETTING HIT. *TR
