I PURCHASED MY 2008 CHEVY IMPALA IN 2009 ABOUT A YR AFTER MY PURCHASE I NOTICED MY REAR DRIVERS SIDE DOOR WOULD NOT LOCK OR UNLOCK WITH EITHER THE KEYLESS REMOTE OR THE LOCK BUTTON ON THE DOOR SINCE THEN THE FRONT PASSENGER DOOR LOCK HAS DID THE SAME THING. BUT THE FINAL STRAW WAS NOW THE REAR PASSENGER DOOR HAS WENT OUT. THAT IS UNACCEPTABLE TO ME AND MY FAMILY I HAVE TWO SMALL GRANDBABIES ONE OF THEM WITH CANCER, THAT ARE BOTH IN CARSEATS. IF ANY OF THE DOORS LOCK THEY CANNOT I REPEAT CANNOT BE UNLOCKED FROM THE OUTSIDE NOR CAN THEY BE UNLOCKED FROM THE KEYLESS REMOTE OR THE BUTTON ON THE DOOR ONCE THE DOORS ARE LOCKED THE ONLY WAY THEY CAN BE UNLOCKED IS BY TILTING THE SEAT BACK AND MANUALLY UNLOCKING THEM. THIS IS PUTTING MY GRANDCHILDREN IN GRAVE DANGER IF WE ARE IN AN ACCIDENT AND I CANNOT GET TO THEM NO ONE ELSE CAN EITHER UNLESS THEY KNOCK THE WINDOW OUT, WHICH ENDANGERS THE CHILDREN. I DEMAND TO KNOW WHY WHEN IT COMES TO THOUSANDS OF CHILDREN'S LIVES BEING PUT IN DANGER BY A DEFECT OF YOUR PRODUCT THAT YOUR COMPANY IS DRAGGING YOUR FEET ON RECALLING THESE CARS. YOUR RECALLING MILLIONS OF CARS FOR THIS DEFECT AND THAT DEFECT BUT YOUR # 1 PRIORITY SHOULD BE TO PROTECT THE CHILDREN THAT CANT PROTECT THEMSELVES. AND ALL US PARENTS/GRANDPARENTS ARE AT OUR WITS END. WE BOUGHT YOUR PRODUCT IN GOOD FAITH NOW ITS TIME FOR YOUR COMPANY TO DO WHAT'S RIGHT RECALL ALL THESE -2008- AND OTHER CHEVY IMPALAS FOR FAULTY DOOR ACTUATORS BEFORE CHILDREN GET HURT OR GOD FORBID KILLED . VERY WORRIED AND UNHAPPY GRANDMOTHER. *TR

WAS DRIVING ON BUSY ONE LANE ROAD, REDUCED SPEED, CHECK TRACTION CONTROL, CHECK ENGINE LIGHT CAME ON AND CAR SLOWED DOWN TO 45 AND WOULD NOT GO ANY FASTER, WAS ABLE TO PULL OFF OF ROAD AND SHUT CAR OFF STARTED ABOUT 5 MINUTES LATER NO INDICATION OF THE PROBLEM. TWO DAYS LATER THE PROBLEM CAME BACK. WENT TO INTERNET TO CHECK PROBLEM SEEMS LIKE THERE HAVE BEEN 100,000 S OF THESE PROBLEMS MANY RESULTING IN ACCIDENTS. IT DOES NOT SHOW THAT THERE HAS BEEN A RECALL. THIS IS VERY SERIOUS IF I WOULD HAVE BEEN ON A FREEWAY WITH TRUCKS TRAVELING AT HIGH SPEED I COULD HAVE BEEN KILLED. WHAT HAS THE VEHICLE SAFETY BOARD DONE TO PROTECT OWNERS OF FAULTY VEHICLES? *TR

OUR 2008 IMPALA LS, WITH 100,000 MILES, IS HAVING THE SAME PROBLEM I AM SEEING AT THIS WEB SITE AND ALL ACROSS THE INTERNET. LAST MONTH, MAY, 2014, AND THIS MONTH, JUNE, 2014, THERE WAS A SUDDEN REDUCED POWER ALERT ON THE DASHBOARD AND THE CHECK ENGINE LIGHT CAME ON. THE SPEED IMMEDIATELY DROPPED TO NO MORE THAN 35 MPH. BEFORE I COULD GET IT TO ADVANCE TO HAVE THEM CHECK TO SEE IF ANY CODES HAD BEEN DROPPED BY THE COMPUTER, THE CHECK ENGINE LIGHT WENT OFF. THERE WAS NO REDUCED POWER MESSAGE EITHER, AND THE SPEED RETURNED TO NORMAL. I WAS TOLD TO TRY FUEL INJECTOR CLEANER, WHICH I DID. ALL WENT WELL FOR ALMOST A MONTH, WHEN THE SAME THING HAPPENED AGAIN THIS MONTH. THIS TIME I WAS ABLE TO GET IT TO ADVANCE WITH THE CHECK ENGINE LIGHT STILL ON. THE COMPUTER HAD DROPPED 2 CODES, BOTH RELATED TO THE ACCELERATOR PEDAL POSITION SENSOR. ADVANCE DID NOT HAVE THE PART, NOR DID AUTOZONE. FORTUNATELY, NAPA DID, FOR $90, INCLUDING TAX. OUR LOCAL CHEVY DEALERSHIP WANTED $50 MORE. SINCE IT IS A VERY EASY PART TO REPLACE EVEN FOR AN AMATEUR LIKE ME, I REPLACED IT. THERE ARE ONLY 2 10 MM BOLTS TO REMOVE AND AN ELECTRICAL CONNECTION TO UNPLUG. SO IT WAS PRETTY SIMPLE, AND SO FAR, THIS HAS DONE THE TRICK, BUT IT'S ONLY BEEN 24 HOURS. THIS APPARENTLY IS A JOB THAT THE DEALERSHIPS WANT TO CHARGE $300 TO $400 TO DO. AS I SAID, THIS IS A WIDESPREAD PROBLEM FOR GM, AND THEY HAVE NOT AND WILL NOT, SO FAR, DO A RECALL. THEY SHOULD. I'M ONLY OUT $90 SO FAR, BUT OTHER PEOPLE ARE OUT MUCH MORE. IF I HAVE THE DREADED, FOLLOW-UP PROBLEM WITH THE THROTTLE BODY, I WILL BE OUT A WHOLE LOT MORE. I SENT AN E-MAIL TO CHEVROLET AFTER THE FIRST INSTANCE, AND DID GET A RESPONSE BACK. I TOLD HIM I DIDN'T WANT TO TAKE ANY FURTHER ACTION UNLESS THIS HAPPENS AGAIN. I WILL BE CONTACTING HIM AGAIN NOW ABOUT THIS LATEST INCIDENT. *TR
MY SEAT BELTS WON'T LOCK PROPERLY. THE PASSENGER BELT HAS THE MOST ISSUES AND YOU HAVE TO PUSH IT IN AND THEN CLICK IT. IN AND THEN YOU CAN'T GUARANTEE IT WILL STAY LOCKED. *TR

THIS IS VERY DANGEROUS BECAUSE IT HAPPENS UNEXPECTEDLY AND CAUSES VEHICLE TO DECELERATE QUICKLY. TYPICALLY THE CAR WILL START NORMALLY AFTER SITTING FOR 15-30 MINUTES BUT CHECK ENGINE LIGHT REMAINS ON FOR SOME TIME. ALSO, THE MESSAGE ENGINE HOT/AC OFF FIRES RANDOMLY.

Official recalls
214V355000 · Electrical System:ignition
Jun 23, 2014
This defect can affect the safe operation of the airbag system. Until this recall is performed, customers should remove all items from their key rings, leaving only the ignition key. The key fob (if applicable), should also be removed from the key ring. General Motors LLC (GM) is recalling certain model year 2005-2009 Buick LaCrosse, 2006-2011 Buick Lucerne, 2000-2005 Cadillac DeVille, 2006-2011 Cadillac DTS, 2006-2014 Chevrolet Impala, and 2006-2007 Chevrolet Monte Carlo vehicles. In the affected vehicles, the weight on the key ring and road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine.
Consequence & remedy
Consequence: If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury. Additionally, a key knocked out of the run position will cause loss of engine power, power steering, and power braking, increasing the risk of a vehicle crash.
Remedy: GM will notify owners, and dealers will install two key rings and an insert in the key slot or a cover over the key head on all ignition keys, free of charge. The recall began on September 23, 2014. Owners may contact General Motors customer service at 1-800-521-7300 (Buick), 1-800-458-8006 (Cadillac), and 1-800-222-1020 (Chevrolet). GM's number for this recall is 14299.

Aug 3, 2012
General Motors (GM) is recalling certain model year 2008-2012 Chevrolet Impala police vehicles because the front lower control arms may fracture. This safety recall does not include non-police Chevrolet Impala vehicles.

Remedy: GM will notify owners, and dealers will replace both front lower control arms, free of charge. The safety recall began on August 21, 2012. Owners may contact the Chevrolet owner center at 1-866-694-6546.

The Agency received a petition on November 14, 2013 requesting an investigation into the operation of the passenger air bag Occupant Classification System (OCS) software logic and algorithm.The petitioner states that due to this alleged defect, the passenger air bag may be suppressed at point of impact and not provided the occupant protection as needed in a crash.On July 22, 2014, NHTSA opened DP14-001 to further review the crash event and perform a more comprehensive search and analysis of the Fatality Analysis Reporting System (FARS).The Agency also collected manufacturers reports on the alleged OCS issue on the subject Impala vehicles and other GM and non-GM peer vehicles.After examination of the petition and available data relating to the subject vehicle's OCS and the specific crash incident where the OCS allegedly failed to operate properly, NHTSA did not identify an issue with the MY2008 Impala involved in the subject crash, nor has it identified a safety-related defect trend existing in the OCS used in the MY 2006-2008 Impala vehicles, in GM peer vehicles or in other non-GM peer vehicles.NHTSA has concluded that further expenditure of the agency's investigative resources is not warranted. The agency accordingly has denied the petition.However, the agency will take further action if warranted by changing future circumstances.
