Electrical system: ignition
- What is wrong
- 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.
- Risk
- 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.

What 2012 Chevrolet Impala owners say
Most recent owner complaints, unedited.
The actuators in the air vents are faulty and I've had to have them repla ed multiple times now. They still continue to make clicking noise sounds and blow cold air in winter/hot air in summer. The trunk deck lid paint is bad. The clear coat has been coming off. Paint all over the car's clear coat has been coming off. There is also some spots where it's down to the metal showing rust/corrosion. Finally, and most seriously, is the car's Traction Control System. It goes off constantly and without warning! It's been doing this randomly, in all types of weather conditions, for some time now. It goes off under normal driving conditions. I barely pull out of a parking space, or make a slow turn, or pull out of a parking lot at a very slow speed and it just goes off. The really dangerous part is that it stalls the car almost to a complete stop, when I've been making a turn well before oncoming traffic, and it stalls almost causing an accident on several occasions now. Most of the incidents are on sunny days where there's no inclement weather! This system is not safe and is unreliable. I've checked many public forums, like Reddit, and there are many other Chevy Impala owners who complain of the same exact problem. Yet Chevy has issued No recalls!? The only recall I've seen close to this is for 2011 year models. Although my car is a 2012, 2011 parts likely were used. If the recall affects 2011 Impalas, then any model that used 2011 parts should be included in this recall. I cannot trust the safety of my car's Traction Control System anymore as it comes on without warning, under no circumstances where it would need to come on. People are in danger with this defect! The car cosmetically, specifically the paint job and the flimsy actuators, are also defective. I've always taken excellent care of my vehicle, regularly having maintenance done at my local Chevy Dealership. Another defect that Chevy had to fix was my fuel pump that went out for no reason! I have receipt for this.
I put my car in reverse and the car turned off and have turn back on. When I try to start it, I don’t hear any fix or crank. Before this happened, my car was slow to change gear or it would will change so fast that my car will lose control and I did not feel safe at all.

I have a 2012 impala that I have had since 2015 and a little while after I got it the engine light came on and it said it was the fuel pump control module requested Mil illumination and evaporated emissions systems leak detected (large leak) and at times the gas tank sparys back at up if you don't let it sit open for a little bit. I have had these issues fixed multiple times and by multiple mechanics who still can't figure out what's going on.

I have a 2012 chevy impala, the traction service control and ABS/stabilitrack keeps giving me issues. I have a grinding noise, decreased power and car will nearly stop on you from time to time, particularly when turning. Taken to dealership, more than one, they keep telling me the harness attach to my traction control system snaps. Ive heard my model has this issue. I see no recall for my VIN, but I have the same issues.
While driving 30 MPH on city streets going straight with a slight incline the A/C and radio powered on and off several times. When stopped at a stop light the doors unlocked and "service stabilitrak" flashed on and off the dash, the radio powered down, and the A/C turned off. After a few second everything went back to normal. No check engine lights came on at all. This is not the first time this has happened.
Traction control light and chime on and off..............car runs ok but chime will drive you crazy.............need to turn it off................
