HAVE 2007 IMPALA LT3. (PURCHASED FROM SUNSET CHEVROLET, SUMNER, WA) 1/13/2010. HAVING SERIOUS TRANSMISSION ISSUES. TOOK VEHICLE TO FIRESTONE (6/10/10) FOR ROUTINE OIL CHANGE AND INSPECTION. FOUND LEAK IN TRANSMISSION. ALSO NEEDED FUEL SYSTEM SERVICE. REPAIRS NOT DONE AT THIS TIME DUE TO FINANCIAL SHORTAGE. TOOK TO FIRESTONE AGAIN FOR ROUTINE OIL CHANGE 8/26/10. DURING ROUTINE INSPECTION OIL LEAK DETECTED. TRANSMISSION LEAKING. AND POWER STEERING MAKING ABNORMAL NOISE. COULD NOT AFFORD REPAIRS. THEN TOOK VEHICLE TO DEALERSHIP. WAS TOLD THAT REPAIRS NOT COVERED BY WARRANTY. COULD NOT AFFORD OUT OF POCKET. TRANSMISSION GOT WORSE AS DID OIL LEAK AND POWERSTEERING. 1/31/11 FIRESTONE SERVICED THE TRANSMISSION AND REPLACED THE LEAKING GASKET. THIS DID NOTHING TO HELP TRANSMISSION ISSUES. CONTACTED GM. WAS EVENTUALLY TOLD THAT EVEN THOUGH BURIEN CHEVROLET TOLD US THE PARTS WERE NOT COVERED BY WARRANTY, THAT IN FACT THE PARTS WERE COVERED BY WARRANTY AT THE TIME WE TOOK IT TO THE DEALER. BUT BECAUSE WE TOOK THE VEHICLE TO AN INDEPENDENT AUTO SHOP, THEIR WAS NOTHING GM COULD DO TO ASSIST US WITH OUR ISSUE. NOW I AM UNSURE HOW TO PROCEED. ANY ADVISE? THANK YOU FOR YOUR TIME.

LETTER TO THE ADMINISTRATOR FROM REPORTING TRANSMISSION SLIPS INTERMITTENTLY IN HIS 2007 CHEVROLET IMPALA SS *TGW THE CONSUMER STATED THE TRANSMISSION PROBLEM USUALLY HAPPENED WHEN STARTING FROM A STANDSTILL OR WHILE MOVING AT A SLOW SPEED. THE CONSUMER TOOK THE VEHICLE TO THE DEALER FOR AN INSPECTION WHERE THEY CHECKED THE SHIFT POINTS, CHECKED THE COMPUTER FOR FAULTS AND INSTALLED A SOFTWARE UPDATE IN THE COMPUTER. THE TRANSMISSION FLUID WAS IN SATISFACTORY CONDITION. THE DEALER STATED THEY WERE UNABLE TO OBSERVE ANY PROBLEMS WITH THE VEHICLE. *JB

NO SIGNS OF FAILURE UNTIL PUT CAR IN PARK. TRIED TO PUT BACK INTO DRIVE AND SHIFT LEVER WOULD NOT MOVE. READ OWNERS MANUAL AND TRIED THEIR RECOMMENDATION, DID NOT WORK. FOUND THE GROUND WIRE FOR THE BTSI HAD BROKE DO TO FAULTY WIRING AT FACTORY, YET CHEVY WILL NOT COVER THE EXPENSE. REPAIR COST $165.60. IF THIS WERE TO HAPPEN IN COLD TEMPS, AN EMERGENCY, AT A TRAIN STOP OR ANYWHERE LIKE THAT IT COULD BE LIFE THREATENING SINCE THEIR IS NO OVERRIDE OTHER THAN TEARING APART CONSOLE TO HIT THE MANUAL RESET. THEIR IS ALSO A TECHNICAL BULLETIN ON THIS ISSUE, TELLING ME IT HAPPENS QUITE FREQUENTLY. *TR

SHIFT GEAR STICKING WOULD NOT MOVE. STRANDED AT 1 AM IN THE MORNING.

PARKED CAR IN DRIVEWAY AFTER COMING HOME FROM WORK. WENT BACK OUT TO GO OUT AND COULD NOT GET CAR OUT OF PARK. HAD TO BE TOWED TO DEALER, SUPPLIED WITH "RENTAL VEHICLE" WHICH I PAID FOR. DEALER STATED BROKEN WIRE IN SOLENOID CONNECTION IN CENTER CONSOLE. *TR

WHEN I AM COMING FROM A STOP AND BEGINNING TO ACCELERATE AT MODERATE RATE BETWEEN 5-25 MILES MY CAR JERKS VERY HARD. THE FEELING IS SOMETIMES TO THE POINT IT FEELS AS IF I HAVE BEEN HIT FROM BEHIND BY ANOTHER CAR. THE FEELING IS VERY FORCEFUL AND IT FEELS AS IF IT BEGINS IN UNDER THE REAR SEATS AND THE REAR TIRES. IT HAPPENS SOMETIMES MAYBE ONCE OR TWICE A DAY AND OTHER TIMES EVERYTIME I PRESS THE GAS UPON COMING OUT OF A COMPLETE STOP AND SOMETIMES IT DOES THIS FORCEFUL JERK/THUMP/SHRUG CONSECUTIVELY AS I COME OUT OF THE COMPLETE STOP AND THEN AS I ACCELERATE A LITTLE MORE. HAVE TAKEN IT TO TWO CERTIFIED GM SERVICE CENTERS ON 3 OCCASIONS AND TOLD THEM THE PROBLEM. AND AFTER THE LAST VISIT THE PROBLEM HAS GOTTEN WORSE. I AM CONCERNED AS WHAT TO DO. AND THE PROBLEM IS PROGRESSIVELY GETTING WORSE. IT HAPPENS DAILY AND ON MOST OCCASIONS EVERYTIME I STOP. *TR

THE VEHICLE WAS PURCHASED IN MARCH 2007 AND IS USED AS A COMMUTER CAR FROM NEW OXFORD, PA TO WASHINGTON, DC DAILY. I AVERAGE 750 MILES PER WEEK. LAST FALL WHEN THE VEHICLE HAD JUST OVER 90,000 MILES, I BEGAN HAVING PROBLEMS FIRST WITH THE CRUISE CONTROL DROPPING OFF SPEED AND NOT RESETTING. THIS QUICKLY ADVANCED TO A SHUTTERING FEEL WHEN ACCELERATING AND OCCASIONALLY PICKING UP SPEED AND WITHIN 50 MILES THE CAR REFUSED TO MOVE AFTER A STOP LIGHT. I TURNED IT OFF AND RESTARTED THE ENGINE AND AFTER PUTTING IT INTO DRIVE, MANAGED TO GET IT TO A NEARBY FORMER CHEVY DEALER. THEY DETERMINED THE TRANSMISSION WAS TOTALLY SLIPPING AND REQUIRED REPLACEMENT. CHEVY STOOD BY THE 100K POWER-TRAIN WARRANTY WITH A NO-COST REPLACEMENT AND INSTALLED A NEW TRANSMISSION, ISSUING A 12,000 MI WARRANTY. TODAY, AT 111,000 MILES, LESS THAN 20,000 INTO THE NEW TRANSMISSION, THE PROBLEM RETURNED. THE FIRST TIME IT WAS ON FLAT GROUND AND I WAS SIMPLY A STALLED NUISANCE IN TRAFFIC. THIS TIME, I WAS GOING UP A HILL AND HAD STOPPED FOR A LIGHT. THE CAR BEGAN TO ROLL BACK DOWN THE HILL, I HAD DIFFICULTY BRAKING AND NEARLY GOT STRUCK BY A LARGE TRUCK. IT WOULD NOT MOVE FORWARD UNTIL I TURNED OFF THE ENGINE AND THEN WITH A THUDS AND JERKS I WAS ABLE TO MOVE IT TO A SAFE PARKING SPOT. THIS TIME I DID NOT HAVE THE DIFFICULTY WITH THE CRUISE CONTROL BUT DID HAVE A BIT OF WHAT I NOW RECOGNIZE WAS TRANSMISSION SLIP BUT I ATTRIBUTED TO THE ANTI-SLIP BRAKES ON ICE. THIS HAPPENED A COUPLE OF TIMES. FROM THE EARLY SHUDDERS, LESS THAN 400 MILES ELAPSED. I WAS FORTUNATE BOTH TIMES. *TR

TRANSMISSION "SLIPS" THEN ENGAGES HARD. HAS PROGRESSIVELY GOTTEN WORSE. HAD TRANSMISSION SERVICE JUST ABOUT A YEAR AGO, FLUID HAS BEEN CLEAN AND FULL. I WAS MAKING A RIGHT HAND TURN AND STARTED TO GO BUT THE CAR WOULD BARELY PICK UP SPEED, THE ENGINE REVVED THEN AFTER ABOUT 3 SECONDS IT JERKED HARD AND RESUMED ACCELERATION. MY LOCAL DEALER AND GM THEMSELVES FLAT-OUT LIES ABOUT THE ISSUES WITH THIS CAR (HAS HAD ALL THE COMMON THINGS, TIRE WEAR, BAD ROTORS, MOTOR MOUNTS, WINDOW SCREECHING, STEERING NOISES, REMOTE ENTRY, YOU KNOW, TYPICAL IMPALA) SO UNLIKELY IT WILL GO TO DEALER FOR DIAGNOSIS. THEY WILL LIKELY SAY IT'S DUE TO POSITION OF THE MOON AND DIRECTION OF THE WIND. JUST HOPE THIS DOES NOT CAUSE ACCIDENT BEFORE I CAN DITCH THIS CAR OR NHTSA GETS ON GM'S CASE FOR THESE DEFECT RIDDEN CARS! *TR

AT RANDOM TIMES, STARTING FROM A STOP, MY 2007 CHEVY IMPALA LTZ CAR WILL SLOWLY ENGAGE 1ST GEAR AND THEN SUDDENLY ENGAGE WITH A STRONG JERK. ON SEVERAL OCCASIONS THIS OCCURRED WHEN PULLING OUT INTO TRAFFIC, STARTING AT A TRAFFIC LIGHT ON A WET ROAD, AND PULLING UP SLIGHT INCLINED DRIVEWAY INTO GARAGE. SEVERAL OF THESE TIMES I'VE LOST CONTROL BRIEFLY FROM MOVEMENT OF THE STEERING WHEEL, DUE TO THE UNEXPECTED POWER OF THE TRANSMISSION ENGAGING AND JERKING. THE DEALER HAS MADE MULTIPLE UNSUCCESSFUL ATTEMPTS AT REPAIRS THROUGHOUT 2008 UNTIL NOW. FROM READING ALL THE OWNER DISCUSSIONS AT EDMUNDS.COM I SEE THIS IS A COMMON PROBLEM AND A SAFETY ISSUE FOR ME. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET IMPALA. WHEN THE CONTACT'S VEHICLE CAME TO A COMPLETE STOP, HE NOTICED THAT THE TRANSMISSION WAS FAILING AND WOULD NOT SHIFT GEARS IN A TIMELY MANNER. HE TOOK THE VEHICLE TO THE DEALER, BUT THEY STATED THAT THE TRANSMISSION WAS FUNCTIONING CORRECTLY. THE DEALER WANTED TO CHANGE THE OIL AND CHARGE AN ADDITIONAL $400 TO DIAGNOSE THE TRANSMISSION. THE CURRENT AND FAILURE MILEAGES WERE 43,678.

THE VEHICLE WAS TURNED OFF, IN PARK, WITH THE PARKING BRAKE ON, IN THE DRIVEWAY AT AN INCLINE. THE VEHICLE ROLLED BACKWARDS DOWN THE DRIVEWAY, AND HIT THE FENCE WHICH BROUGHT IT TO A STOP. THERE WAS DAMAGE TO THE DRIVER SIDE DOOR AND DRIVER SIDE REAR OF VEHICLE. THE CAR WAS TAKEN TO DEALER, AND THE EVENT EXPLAINED. THE DEALER MADE REPAIR TO DOOR AT MY COST. THE DEALER MADE NO ATTEMPT TO DETERMINE THE CAUSE. I CALLED AGAIN TO SERVICE AND SPOKE TO SOMEONE, WHO STATED THAT THE PARKING BRAKE IS NOT SUPPOSED TO PREVENT THE VEHICLE FROM ROLLING BACKWARDS. NO INVESTIGATION WAS OFFERED. *TR

TL*THE CONTACT OWNS A 2007 CHEVROLET IMPALA. THE CONTACT STATED THAT THE VEHICLE BEGAN ROLLING BACKWARDS AT APPROXIMATELY 5 MPH. THE GEAR WAS PLACED IN PARK AT THE TIME. HER ARM WAS TANGLED IN THE STEERING WHEEL AND SHE WAS KNOCKED TO THE GROUND AND DRAGGED DOWN THE DRIVEWAY. THE VEHICLE FINALLY CAME TO A STOP IN THE STREET. THE CONTACT SUSTAINED BRUISES AND SCRAPES ON HER RIGHT FOOT AS WELL AS HER LEFT KNEE DOWN TO HER ANKLE. HER HIPS AND BACK ARE STILL HURTING FROM BEING KNOCKED DOWN. SHE SCHEDULED AN APPOINTMENT WITH THE DEALER TO HAVE THE VEHICLE INSPECTED. THE CURRENT AND FAILURE MILEAGES WERE 9,942.
