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.

While driving at highway speeds the car will act up and the engine will shut off, I get the message on the odometer display that reads, Engine power is reduced, service throttle, starter disabled. This is not a good thing to have happen while driving.

Heating and air conditioning actuators and/or blen door getting stuck so the air will not switch from cold to hot or hot to cold without pulling the glove box out and manually turning them by hand. Heater will blow hot air and then randomly switch to cold air. When it's cold outside, I cannot defrost my windows cause it gets stuck on cold air which impairs visibility.

While wife was driving at normal speed car went into limp mode many times over last few months causing accelerator pedal sensor codes.we have since changed this pedal sensor 6 times and same issue and codes pop up. We also changed throttle body w sensor and connector pigtail.I think there is corrosion in ECM and all these items have failed. These items should have been recalled as manufacturer defects in my opinion.we are still having problems same codes and im not the only one!

When first purchased I had to change accelerator pedal. When I took it to the shop I was told they get a lot of people w impalas same as my year 2008 that needed to have the accelerator pedal changed every so often because they would go out and it would cause the check engine light to go on and off because the vehicle was sending the wrong signals.I would drive on the highway and street it would cause reduced engine to come on and slow my car down almost leading into accidents because I did not know it was about to happen. It would come and go on as it wanted. The electrical part of the car is something in the car continues to drain my battery. I've gotten a new battery and it still drains causing me to have to get it recharged. The suspension I was also told for the year of my car is bad. When purchased I found out that again people that purchased these years of vehicles had problems with the control arms and that I now have to take it to get fixed because one hit to a pot hole can cause the under part of the car to break and cause a bad accident. I did not know impalas had this many problems. I seen the police impalas for 2008 were recalled for suspension, but they all seem to share this common problem as well as the actuator continuously clicking. It seems to be an easy fix, but I shouldn't have to fix something that is a common problem for the impalas.
