2008 Chevrolet Impala

TL* THE CONTACT OWNS A 2008 CHEVROLET IMPALA SS. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, HE NOTICED A WARNING THAT STATED ENGINE POWER REDUCED. IMMEDIATELY AFTER, THE VEHICLE DECELERATED. THE VEHICLE WAS LATER TAKEN TO DEALER. AFTER INSPECTION, THEY ADVISED HIM THAT THEY WERE UNABLE TO DIAGNOSE THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS CONTACTED AND THEY OFFERED NO ASSISTANCE. THE FAILURE MILEAGE WAS APPROXIMATELY 75,000. THE CURRENT MILEAGE WAS APPROXIMATELY 75,500. *TR

TL* THE CONTACT OWNS A 2008 CHEVROLET IMPALA. THE CONTACT STATED THAT THE REAR WHEELS WERE NOT ALIGNED AND CAUSED THE REAR TIRES TO WEAR PREMATURELY. THE CONTACT TOOK THE VEHICLE TO A LOCAL MECHANIC TO HAVE THE TIRES REPLACED. THE MECHANIC DID NOT KNOW WHY THE TIRES WERE WEARING PREMATURELY HOWEVER THE TIRES WERE REPLACED. THE CONTACT STATED THAT THE VEHICLE WOULD BECOME UNCONTROLLABLE WHEN DRIVING IN INCLEMENT WEATHER AT 40 MPH. THE CONTACT DID NOT TAKE THE VEHICLE TO A DEALER FOR A DIAGNOSTIC TEST. THE FAILURE MILEAGE WAS 46,000.

I WAS DRIVING ON THE HIGHWAY AT APPROXIMATELY 60 MPH AND MY CHECK ENGINE AND TRACTION CONTROL LIGHT CAME ON. ADDITIONALLY, THE DASH ALTERNATELY FLASHED BETWEEN "SERVICE TRACTION CONTROL" AND "REDUCED ENGINE POWER." MY CAR SLOWED DOWN, BUT NEVER CUT OFF. MY ACCELERATION WASN'T WHAT IT NORMALLY IS. I WAS ABLE TO MAKE IT TO MY DESTINATION, BUT WAS NOT A FUN EXPERIENCE. *TR

THE RIGHT REAR DOOR LOCK WORKS INTERMITTENTLY WITH MY POWER DOOR LOCK SYSTEM ON MY 2008 CHEVY IMPALA. ALSO THE RIGHT FRONT PASSENGER DOOR LOCK WORKED INTERMITTENTLY AT FIRST AND NOW IT DOES NOT RESPOND. I HAVE DONE SOME RESEARCH ONLINE AND I KNOW I AM NOT THE ONLY OWNER OF A 2008 CHEVROLET IMPALA WITH THIS PROBLEM. PLEAS HELP. IS THERE ANY WAY A RECALL CAN BE ISSUED TO GET THIS ISSUE FIXED? IT IS IMPOSSIBLE TO UNLOCK THE RIGHT REAR DOOR FROM THE OUTSIDE WITH A KEY BECAUSE THERE IS NO KEY HOLE. THERE IS ONLY ONE KEY HOLE ON TO UNLOCK A DOOR WITH THE CAR KEY AND IT IS ON THE DRIVER SIDE DOOR ONLY. *TR

ON MARCH 14, 2013, WE WERE ACCELERATING FROM A COMPLETE STOP WHEN THE SERVICE ENGINE LIGHT CAME ON AND A MESSAGE APPEARED IN THE MESSAGE CONSOLE THAT READ "ENGINE POWER REDUCED." IT WAS DIFFICULT TO GET THE VEHICLE TO ACCELERATE AT FIRST, BUT IT THEN RESPONDED AFTER A FEW SECONDS. THE 'SERVICE ENGINE" LIGHT STAYED ON. WE TOOK IT TO AN AUTOMOBILE PARTS STORE SO THEY COULD PULL THE CODE WITH A CODE READER. THE VEHICLE PARTS STORE WAS ABLE TO PULL A CODE READING P2138 WHICH IS FOR THE THROTTLE POSITION SENSOR. LATER ON THAT NIGHT, I WENT ONLINE AND DID SOME RESEARCH AND DISCOVERED THAT THERE ARE MANY OWNERS OF 2008 CHEVY IMPALAS WITH THE SAME PROBLEM. IN THE PAST YEAR, THERE HAVE BEEN SEVERAL OCCASIONS WHEN MY 2008 CHEVY IMPALA TENDS TO BUCKLE AND JERK OR HESITATE WHEN ACCELERATING FROM A COMPLETE STOP MAKING DIFFICULT TO NEARLY IMPOSSIBLE TO NAVIGATE OUT OF THE WAY OF TRAFFIC. IS THERE ANY WAY A RECALL CAN BE ISSUED FOR THE THROTTLE POSITION SENSOR AND THE GAS PEDAL SO THIS ISSUE CAN BE RESOLVE FOR ALL OWNERS OF 2008 CHEVROLET IMPALAS? PLEASE HELP. *TR

GEAR SHIFT STUCK IN PARK POSITION. WOULD NOT SHIFT INTO ANY OTHER POSITION. CHEVROLET MECHANIC FOUND ELECTRICAL PROBLEM AND MADE FOLLOWING COMMENTS ON THE REPAIR ORDER. FOUND THAT SHIFT LOCK CONTROL SOLENOID INOP. FOUND THAT GREEN WIRE MELTED ABOUT 12 INCHES FROM SHIFTER AND ALSO CONNECTOR FOR SHIFT LOCK CONTROL HAD HIGH RESISTANCE.. REPAIR COMMENTED: REPLACED CONNECTOR AND REPAIRED WIRE WORKING AS DESIGNED AT THIS TIME. MECHANIC STATED THAT THIS WAS NOT UNCOMMON. ALSO FOUND NUMEROUS INTERNET FORUM COMMENTS ABOUT THIS PROBLEM.. VERY SERIOUS FIRE HAZARD. GM SEEMS TO BE AWARE SINCE ABOVE REPAIR IMPLIES A REWORKING DESIGN OF WIRE WORKING.: EVIDENCE OF BURNED WIRE INSIDE A VEHICLE SHOULD BE CONSIDERED A SERIOUS FIRE HAZARD. *TR

2008 CHEVY IMPALA. RIGHT REAR DOOR LOCK BEGAN WORKING INTERMITTENTLY. RIGHT FRONT FOLLOWED SUIT SHORTLY AFTERWARDS. NOW, SOME 5 MONTHS LATER, THE DRIVER DOOR IS BEHAVING THE SAME WAY. IT MAKES TRANSPORTING MY CHILDREN DIFFICULT AND UNSAFE. IF THERE WERE TO BE AN ACCIDENT, THE CHILDREN IN THE BACK SEAT ARE NOT LIKELY TO HAVE THE MENTAL CAPACITY TO REMEMBER TO UNLOCK THE DOOR WHICH COULD LEAD TO FURTHER INJURY OR DEATH. WIRING HARNESS IN THE CENTER CONSOLE IS POORLY DESIGNED AND LOCATED IN SUCH A WAY THAT THE WIRING BREAKS AND MAKING IT SO ELECTRICAL SAFETY DEVICES DO NOT DISENGAGE THUS NOT LETTING THE KEY BE REMOVED, THE VEHICLE NOT BEING ABLE TO SHIFT FROM PARK, AND OTHER FAILURES YET TO BE IDENTIFIED. *TR

REAR TIRES HAD EXCESSIVE WEAR ON THE INSIDE OF THE TIRE TO THE POINT THAT THE THREAD AND WIRES WERE SHOWING. REPLACED ALL FOUR TIRES AND WHEEL ALIGNMENT. IN JULY 2012 HAD TIRES AND SHOCKS REPLACED FOR THE SAME ISSUE. BIG KNOTS WERE ALSO ON THE TIRES AND CAR SHOOK WHEN GOING AT A LOW SPEED. WAS TOLD THAT REAR SUSPENSION WAS MISALIGNED AND THAT REAR SHOCKS WOULD FIX THE PROBLEM. MARCH 2013 TIRES FOUR TIRES REPLACED AND WHEEL ALIGNMENT AGAIN. WAS TOLD THAT CAMBER BOLTS WERE NEEDED TO FIX THIS PROBLEM. CONTACTED GM IN JULY 2012 ABOUT THE PROBLEM AND REP STATES THAT THERE WAS NO RECALL FOR THIS VEHICLE ONLY THE POLICE MODELS. THIS IS UNFAIR FOR CONSUMERS TO HAVE TO KEEP BUYING TIRES. VEHICLE CURRENTLY HAS 88560 MILES. *TR

I WAS DRIVING ON THE HIGHWAY LEADING INTO AN OVERPASS. AS L ENTERED ONTO THE OVERPASS MY SERVICE TRACTION CONTROL, ENGINE POWER REDUCED, AND SERVICE THROTTLE BODY DISABLED FLASH ACROSS MY DASH BOARD, KILLING THE POWER TO MY VEHICLE AND LOCKING MY STEERING WHEEL. WHILE I WAS STOPPED UNABLE TO MOVE MY VEHICLE, CARS FLEW ME AND I WAS ALMOST HIT. AT ONE POINT ANOTHER VEHICLE WAS ALMOST RAN OFF THE ROAD DUE TO ONCOMING TRAFFIC TRYING TO DODGE ME. THIS WAS THE WORST EXPERIENCE OF MY LIFE. I HAVE NEVER FEARED FOR MY LIFE LIKE I DID AT THIS TIME. AFTER DOING MY RESEARCH ONLINE, I HAVE FOUND MANY OTHERS HAVE BEEN IN MY SITUATION. I WAS TOLD THAT MY ACCELERATOR PEDAL SENSOR HAS GONE BAD. I FEEL THAT GM SHOULD BE HELD RESPONSIBLE AND NEEDS TO REMEDY THE SITUATION BEFORE SOMEONE IS KILLED. *TR

WHEN TAKING OFF FROM A START THE TRANSMISSION DOESN'T ENGAGE CAUSING THE ENGINE TO REV, THEN IT SLAMS INTO GEAR EVENTUALLY. HAVE ALSO NOTICED A DECREASE IN POWER SOMEWHAT. HAVE HAD IT IN THE DEALER FOR SERVICE 3 TIMES AND OF COURSE THEY SAY THEY CANT FIND ANYTHING WRONG WITH IT. KINDA CRAPPY SINCE THE WARRANTY JUST WENT OUT ON THE DRIVE TRAIN ABOUT A MONTH AGO. PROBLEM ONLY SEEMS TO BE GETTING WORSE. I HAVE READ ON FORUMS OF THIS ISSUE ON NUMEROUS VEHICLES THAT USE THE 4T65-HD TRANSMISSION AND THAT GM REFUSES TO ACKNOWLEDGE THAT THERE IS A FLAW IN THESE TRANSMISSIONS. *TR
