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).

What is wrong: Gm is recalling certain model year 2006-2009 buick, lucerne; cadillac dts; hummer h2; model year 2008-2009 buick enclave; cadillac cts; model year 2007-2009 cadillac escalade, escalade esv, escalade ext; chevrolet avalanche, silverado, suburban, tahoe; gmc acadia, sierra, yukon, yukon xl; saturn outlook; and model year 2009 chevrolet traverse vehicles equipped with a heated washer fluid system (hwfs). A recall was implemented in 2008 to add a fuse to the control circuit harness to address the potential consequences of a printed circuit board (pcb) electrical short. However, there have been new reports of thermal incidents on hwfs modules after this improvement was installed. These incidents resulted from a new failure mode attributed to the device's thermal protection feature. The significance varies from minor distortion to considerable melting of the plastic around the hwfs fluid chamber.
Risk: It is possible for the heated washer module to ignite and a fire may occur.
Remedy: Dealers will permanently disable and remove the heated washer fluid module. An updated page for the owner manual will be provided and inserted in the owner manual to document that the feature has been permanently disabled and removed from the vehicle. The safety recall began on june 11, 2010.

I purchased the vehicle a week before the incident. There were no warning lights or messages and nothing to indicate there was a problem. I was driving in a crowded parking lot so I was going very slow. When I turned my car suddenly died. My husband was passenger and my daughter and 2 sons were in the back. Smoke started coming from the seat and we all rushed out of the car while the seat was on fire. my husband pulled the seat out and put the fire out. I was not aware the battery is located under the back seat. I had the car towed and inspected by a mechanic. I was told the battery does not have a cover so the metal from the seat was touching the battery causing the fire. The battery is a top post battery that is recommended for this vehicle. I can find no information about a battery cover. The vehicle is available for inspection. I have photos and the report from the mechanic but I'm having trouble uploading them

Vehicle shuts off due to fuel pump relay connection problem which is due to the back seat rubbing against the fuse box

Our Buick Lucerne would crank but wouldn't turn over when trying to start after trying to pick up take out. 1) It was suggested to me by a passerby that it sounds like a fuel pump relay. 2)I started to smell something burning. The passerby who happens to be familiar with Buick Lucerne tried to help. He lifted the back seat and showed me the fuel pump relay which was burned. Then he switched the electrick window relay which is the exact same relay switch and the car started. Went immediately to an autozone and bought spare fuel pump relay. Thought that solve the problem, but every 2 to 3 days I'd smell that burning smell. 3) The mechanic I've been going to for 10 years confirmed the issue 4)Have not taken to dealer or insurance rep 5)Absolutely no visual warning on dashboard. the warning happens when I start smelling the burning odor. Started one and a half months ago....

The transmission started not shifting as I was driving down the road and the relay fuse box caught on fire and I think it’s where the back seat lays on top of the fuse box which rubs the fuses. Which is dangerous bc it catches on fire and could blow the car up while driving
