WHILE I WAS DRIVING, THE CAR GAVE A NOTICE OF REDUCED ENGINE POWER, THEN A FEW MILES LATER, ANOTHER NOTICE CAME ON SERVICE THROTTLE DISABLING SERVICE. AND THE CAR SHUT OFF! WITH NO WARNING, AND NO WAY TO GET TO SAFETY. IF I WASN'T IN AN AREA THAT HAD A SHOULDER I COULD GET TO QUICKLY OR IF THERE WAS ANY TRAFFIC NEAR ME, I WOULD BE DEAD! THIS IS INCREDIBLY UNSAFE AND IS GOING TO GET SOMEONE KILLED, IF IT HASNT ALREADY! THAT HAS TO BE SOME SORT OF FLAW IN THE PROGRAMING. IF I WOULD HAVE BEEN ON THE HIGHWAY, WHICH IS WHERE I NORMALLY AM AT THAT TIME OF DAY, I WOULD HAVE HAD NO TIME TO REACT AND GET TO A SAFE AREA BEFORE THE CAR SHUT DOWN ON ME. IT ALSO LOCKED UP THE STEERING WHEEL AND BRAKING SYSTEM SO I HAD NEXT TO NO POWER. IT WAS INCREDIBLY SCARY. I AM JUST GLAD THAT I WAS DRIVING THE CAR, INSTEAD OF MY ELDERLY MOTHER. SHE VERY WELL MAY HAVE HAD A HEART ATTACK FROM THE FEAR. IN NO WAY SHOULD A CAR JUST SHUT DOWN MID-DRIVE LIKE THAT! I CANT EVEN BEGIN TO EXPLAIN THE AMOUNT OF WAYS HOW BADLY THAT COULD GO WRONG, AND THIS SEEMS TO BE A COMMON ISSUE WITH CHEVY VEHICLES AND THE THROTTLE BODY. EVEN IF THE THROTTLE BODY IS GOING BAD, IN NO WAY SHOULD YOUR CAR BE PROGRAMED TO JUST SHUT OFF MID-DRIVE, EVER. I REALLY HOPE THAT IS A PROGRAMING FLAW AND NOT INTENTIONAL, BECAUSE IF THAT IS INTENTIONAL, YOU ARE TRULY TRYING TO KILL PEOPLE. WHAT IS IT GOING TO TAKE FOR CHEVY/GM TO GET THE ISSUE FIXED? HOW MANY PEOPLE GETTING KILLED IN UNNECESSARY ACCIDENTS IS IT GOING TO TAKE? I PRAY THAT MYSELF OR MY FAMILY ISN'T ONE OF THEM! PLEASE CHEVY/GM, GET THIS ISSUE FIXED ALREADY.

2008 CHEVY IMPALA LTZ -- I AM HAVING TROUBLE WITH THE REAR INNER TIRES WEARING DOWN TO THE CHORDS JUST LIKE ALL THE OTHER COMPLAINTS ON HERE. I KNOW IT'S NOT THE TIRE BRAND, ETC. AS I'VE HAD A REPUTABLE MECHANIC PUT ON TWO SETS OF TIRES. I FOUND ARTICLES ON A LAWSUIT AND THE FACT THAT GM WILL FIX THE POLICE CARS WITH THIS ISSUE, BUT NOT THE GENERAL PUBLIC'S. I BOUGHT THIS CAR AS A COMMUTER CAR FOR MY SONS THAT WILL BE COLLEGE STUDENTS AND I NEED IT TO LAST. I WANT A COPY OF THE TSB #08032A THAT ADDRESSES THIS ISSUE. I JUST WANT MY CAR FIXED SO THAT I DON'T KEEP BLOWING THROUGH SETS OF TIRES IT IS GETTING RIDICULOUSLY EXPENSIVE. MY LAST SET WAS SUPPOSED TO WEAR OUT AT 60,000 AND ONLY LASTED 20,000. I AM ACTUALLY ON MY SECOND SET, SO BASICALLY $1600 INTO TIRES ALONE, NOT TO MENTION WHAT IT'S GOING TO COST ME FOR THE SPINDLE/CAMBOR/REAR TIE RODS THAT IS ASSOCIATED WITH THE TSB MENTIONED ABOVE. GM SHOULD BE PAYING FOR THIS AND IT SHOULD BE A MASSIVE RECALL. THESE CARS ARE PROLIFIC IN SOCIETY. LOL....WE BAILED THEM OUT IN 2008, AND THEY WERE CRANKING OUT LEMONS THE SAME YEAR....IRONIC!! GM REFUSES TO TAKE RESPONSIBILITY.

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

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.
