Engine and engine cooling: exhaust system: manifold/header/muffler/tail pipeReported October 26, 2015 · 1,003,556 vehicles affected
What is wrong
General Motors LLC (GM) is recalling certain model year 1998-1999 Chevrolet Lumina and Oldsmobile Intrigue, 1997-2004 Buick Regal and Pontiac Grand Prix, 2000-2004 Chevrolet Impala, and 1998-2004 Chevrolet Monte Carlo vehicles. The affected vehicles were previously repaired under recalls 08V‑118, 09V‑116, and 15V‑201 to address the possibility that engine oil may drip onto the hot exhaust manifold.
Risk
Engine oil that drips onto the hot surface of the exhaust manifold may result in a fire.
Remedy
The remedy applied under recalls 08V‑118, 09V‑116, and 15V‑201 did not adequately remove the safety risk. Under the improved remedy, dealers will replace the engine’s front valve cover and gasket. Vehicles that are covered by recalls 08V‑118, 09V‑116, or 15V‑201 that have not yet received the original remedy will instead receive the improved remedy under the original recall number. The recall began on February 19, 2016. Owners may contact Chevrolet customer service at 1‑800‑222‑1020, Buick customer service at 1‑800‑521‑7300, Oldsmobile customer service at 1‑800‑442‑6537 and Pontiac customer service at 1‑800‑458‑8006. GM's number for this recall is 15757. Note: Until the improved remedy has been applied, owners are advised to park their vehicle outside since the fire risk exists even when the vehicle is unattended.

Electrical system: ignitionReported July 3, 2014 · 5,877,718 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) notified the agency on July 3, 2014, that they are recalling 5,877,718 model year 2000-2005 Chevrolet Impala and Monte Carlo, 1997-2003 Chevrolet Malibu, 2004-2005 Malibu Classic, 1999-2004 Oldsmobile Alero, 1998-2002 Oldsmobile Intrigue, 1999-2005 Pontiac Grand Am and 2004-2008 Pontiac Grand Prix vehicles. In these models, the weight on the key ring and/or 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.
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 9, 2014. GM's number for this recall is 14350.

Some of these vehicles have a condition in which drops of engine oil may be deposited on the exhaust manifold through hard braking.
Risk

Remedy
Dealers will replace the engine’s front valve cover and front-valve-cover gasket with new parts of an improved design and remove the engine’s plastic cover and plastic oil-fill-tube extension, free of charge. The recall is expected to begin during may 2016.

Last time I drove it back it stalled out and smelled over heated

The service manager told me the Engine cover will be removed and NOT replaced. This downgrades the vehicle as the engine cover is part of the appearance element and gives a certain amount of protection to some components and wiring harnesses. It will soon be a Classic and the engine cover is part of the original equiptment that needs to be on it. There is NO logical reason the valve cover gasket cannot be replaced AND keep the engine cover in place. Thank you for your help.
