Electrical system: ignitionReported June 23, 2014 · 3,141,731 vehicles affected

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 the car down the road it will "randomly" shut off. Giving no indication other then dimming lights. Neither the dealership or the garage I went to can explain it. The power steering doesnt work and has almost caused me to crash on the highway and town roads.

Filed Oct 25, 2018 · Electrical · PA

I was driving my car everything was perfectly working.I parked for the night behind my house no problems. I went to drive my car the next morning and all of the dash gauges as well as the reverse lights were out. I took it to an auto repair shop with no explanation as to what was going on. The cluster panel was replaced with no luck of the problem being resolved. Fuses were replaced also. This is not only upsetting but it is also dangerous. I can not and do not drive the car because of this issue. How do I know how much gas I have or how fast I am traveling. After doing some research, this is a problem that has come up before with no solution. Something needs to be done about this issue.
