THIS VEHICLE HAS BEEN RECALLED DUE TO AIR BAGS, AND IN A YEAR NO ONE HAS BEEN ABLE TO GET THE REPAIRS DONE TO THE VEHICLE. BUT FURTHERMORE THE CAR HAS SEVERAL OTHER MECHANICAL ISSUES THAT I AM SHOWING AS A TREND WITH IMPALAS BEING THAT MY SISTER AND COUSIN HAVE ONE ALSO IN DIFFERENT YEARS, THE CAR MAKES A TICKING NOISE WHEN THE AIR OR HEAT IS TURNED ON THE PASSENGER SIDE DELIVERS OPPOSITE TEMP AS THE DRIVER SO IF AIR IS ON THE PASSENGER WILL DELIVER HEAT AND VICE VERSA. IF THE CAR GOES OVER A SPEED BUMP THE ENGINE REDUCES POWER AND SERVICE STABILITRAK APPEARS ACROSS THE LIGHTING AS WELL AS THE CAR DROPPING OUT OF GEAR IF I GO OVER ANY BUMP. THIS IS VERY DANGEROUS ESPECIALLY BEING THAT MY CHILDREN AND I WERE IN THIS CAR AND IT DECIDED TO DO THIS ON THE INTERSTATE AT NIGHT IN 70 MPH TRAFFIC. AFTER DOING RESEARCH ON THE VEHICLE I AM SHOWING THAT I AM NOT THE ONLY PERSON WITH ALL OF THESE PROBLEMS LISTED, AND IT BOTHERS ME THAT NONE OF THESE ISSUES HAVE BEEN RECALLED JUST AS THE AIR BAGS WERE EVEN THOUGH I THINK THE RECALL, IS JUST TO SAVE FACE BECAUSE NO ONE IS ACTUALLY DOING THE WORK TO GET THEM FIXED. AT FIRST I THOUGHT THESE THINGS WERE JUST MECHANICAL PROBLEMS WITH AGE OF CAR BUT AFTER RESEARCH THESE ARE ISSUES THAT ARE IN CARS MADE IN THIS TIME FRAME AND WARRANTS A RECALL FOR THE SAFETY OF CONSUMERS.

REDUCED ENGINE POWER MESSAGE, FAULTY BACK DOOR LOCKS, HEATING ACTUATOR REPAIRS. THIS IS A REVISED COMPLAINT TO ONE I ALSO MADE FOR JUST THE REDUCED ENGINE POWER MESSAGE. AFTER READING NUMEROUS COMPLAINTS ON HERE I HAVE FOUND THAT MY CAR HAS SEVERAL OF THE ISSUES NOT JUST REDUCED ENGINE POWER. I AM MOST CONCERNED WITH THE CAR CUTTING OUT WHILE DRIVING DUE TO THE REDUCED ENGINE POWER HOWEVER WE ALSO HAVE LOCKS THAT DON'T OPEN/LOCK WITH REMOTE WHICH HAS BEEN GOING ON FOR THE LAST 3 YEARS AND SINCE LAST WINTER HEATER ONLY BLOWS COLD AIR UNTIL YOU ACCELERATE THE CAR. THIS MONTH WE HAD CAR REPAIRED FOR A KNOCKING NOISE COMING FROM UNDER GLOVE BOX WHILE CAR WAS RUNNING OR SHUT OFF. MECHANIC DIAGNOSED AS A NEW ACTUATOR AND DID REPAIR. THIS HOWEVER DID NOT REPAIR THE BLOWING OF COLD AIR AND ALSO THIS IS WHEN THE REDUCED ENGINE POWER WARNING STARTED. I AM A FORMER GMAC EMPLOYEE AND HAVE HAD GM VEHICLES FOR THE LAST 15 YEARS. I AM SO DISAPPOINTED THAT THERE ARE SO MANY PROBLEMS WITH THIS MAKE/MODEL AND THAT GM HAS NOT ISSUED A RECALL ON THESE.

(REDUCED ENGINE POWER) MY 2008 CHEVY IMPALA RANDOMLY SHOWS DOWN AFTER THE DASH READS REDUCED ENGINE POWER. I AM LUCKY TO BE ALIVE I WAS DOING ABOUT 60 ON THE EXPRESSWAY AND THE CAR SPEED JUST DROPPED TO 20MPH I HAD TO SWERVE BECAUSE THE CAR BEHIND COULD NOT SLOW DOWN IN TIME. MY TWO YEAR OLD WAS IN THE CAR AND I HEAR THAT GM CARS HAVE THIS PROBLEM ALL THE TIME. THIS IS RIDICULOUSLY DANGEROUS SOMEONE HAS TO DO SOMETHING ABOUT IT. THE GM DEALERSHIP HAS NO IDEAL HOW TO FIX THIS.

Official recalls
2Jun 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.
Consequence & remedy
Consequence: A broken control arm can result in the loss of control of the vehicle, increasing the risk of a crash.
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.

Status: closed (inferred from source dates) · Air Bags; Air Bags:frontal:sensor/control MODULE-INACTIVE
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. The official petition denial, as published in the Federal Register, is available in the document file for this defect petition.The single complaint and crash noted in the Failure Report above is the petitioner's VOQ (10568388) and can be reviewed online at https://www.nhtsa.gov/recalls?nhtsaId=10568388.
