Component: ELECTRICAL SYSTEM:IGNITION
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: 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.
Component: SUSPENSION:FRONT:CONTROL ARM:LOWER ARM
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: 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.
After getting into my parked car and starting it, the Stabilitrak warning message came on my display. This is the 2nd tike that this occurred. The first time it occured, my mechanic diagnosed it as a failed throttle body, which I replaced myself, (easy removal/installation). Now, a couple of months later, it occurred again. After doing some online research, it seems as though the position sensor on the accelerator pedal may be at fault. A lot, if not most cars today have a "fly-by-wire" system which replaces cables and such with sensors and motors. So, the accelerator, (gas), pedal controls the movement of the butterfly valve on the throttle body by sending a signal to the motor. I'm going to replace that... about $140 or so. I saw a YouTube video and the removal/installation is fairly easy. A lot of people are having this issue; maybe a recall is needed?
Service stabilitrak warning, followed by reduced engine power, then car starts jerking.
i own a 2011 chevy impala 4 door that has a very serious engine issue. I was on my way home and suddenly the service stability trac, and check engine light came on, then the message center displayed reduced engine power and low oil pressure then the engine shut off. I tried to restart the vehicle and it would not restart. I got it towed to a parking lot where it sat over night then it would restart but only for a few minutes. Once I got a scanner hooked up it had a p0642 code lost 5 volt reference circuit 1 and a cam sensor code I worked on this vehicle for two days and still have not found the issue. this vehicle needs a recall since this is a recurring issue with a few different model years of this vehicle and its always the same issue word for word, check engine light comes on, service stability trac, reduced engine power and low oil pressure lights come on the same p0642 lost 5 volt reference circuit 1. This is a very dangerous situation when going down the road and you lose engine power, steering and braking power. GM needs to correct this issue too many people have had this same issue.

Service stabilitrak warning light goes off and on intermittently when this happens the traction control light comes on when hooked up it shows no codes everything I’ve read on line is that it’s a electrical issue to replace wheel bearings or gas pedal or other list of sensors shouldn’t this be something that you should investigate to let owners know what to fix it seems to be a issue on several different models of Chevy autos if forums are correct next step is it will go into limp mode or shut off completely that one would think would be a serious safety issue as you loose power steering as you have to fight to get to shoulder of the highway
Today, 6-12-2022, driving on US Highway 80 at 65 mph headed toward Phenix City, AL from Columbus, GA, the the engine shuddered, then the "Stabilitrack Service Light" came on, along with the check engine light, and a message for "reduced engine power." Then, the engine suddenly cut out as I was going uphill between the Riverchase Exit and the Summerville Exit. Luckily, I was driving and not my wife. I was able to glide the car back to the right shoulder of the road under ZERO power, and shut the ignition down. Cars were passing me at 65-75 mph, and I was very fortunate not to have caused an accident. After sitting there for about 5 minutes in 96 degree heat and my wife freaking out in the passenger seat, I restarted the car and eased it to the Summerville Exit, and slowly drove home, about another 6 miles. We were damn lucky not to have been hit by another car, as this happened on a what is essentially a freeway. After researching this , it seems this is a common problem being reported on this Model, the Chevy Impala. I'm sure Chevrolet knows about this...the company should be forced to recall this car model and fix it before folks start getting killed due to total engine failure...especially at a high speed like I was driving.
The seat belt will not click in place. I have to push the release button several times to get the seat belt to click in place. It will release with no problem. It seem like something either came loose or broke off
The car was stopped at a stop sign, turned right onto the highway and the front wheels locked. The car would not move in any gear, even in neutral. A tow truck had to place front wheels on skids and drag onto the bed. The transmission repair shop never saw anything like it, all the gears on the trans axel were stripped smooth and metal fragments all over the inside of the transmission. Very dangerous situation if there would have been oncoming traffic.
