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.

Recall number 15V201000 · Recall details

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.

Service brakes, hydraulicReported June 23, 2004 · 47,991 vehicles affected
What is wrong
Certain passenger vehicles were produced with lower than specified torque on both front brake caliper to steering knuckle attachment bolts. With improper torque, the clamp load at the joint may not be adequate to prevent movement between the caliper bracket and knuckle.
Risk
Depending on whether one or both bolts backs out or fractures, the result can be locking of the affected wheel during braking and an abrupt steering input in the direction of the locked wheel, reduced braking and noise from the affected wheel, or severing of a brake hose, increased brake pedal travel, and reduced steering control. Reduced braking or steering control could cause a crash.
Remedy
Dealers are to tighten both bolts to the specified torque. Owner notification began on june 28, 2004. Owners should contact chevrolet 1‑800‑630‑2438 or pontiac 1‑800‑620‑7668.

I took my car into john hall chevrolet on 5/19/2017 to have the ignition recall done.prior to my taking it there I was experiencing several issues with my car that no single diagnostic could quite pinpoint.needless to say I replaced several things yet to no prevail.the car would just stop running luckily before I reached over 10 MPH and on several occasions while trying to turn in traffic I lost power steering.all while the key was in the on position.finally a more updated sensor scanner detected an electrical issue within the ignition itself.when I went to the dealership I was told they would only do what the recall required them to do. Even though I told them what it was doing and asked if they could check to make sure I didn't have to worry about leaving there and the car shutting off and /or no power steering I was told no .I would have paid to know,to have them scan it, whatever.needless to say after they fixed their part the car is still doing the same thing.even when the man brought me my car I asked how did she start? He said not good and walked away. Also I left them with 1 key shouldn't there have been something done to both? My car may be old but she's been well maintained .great strong motor and alot of new parts. The starter and fuel pump were pretty much wrecked by the little electrical issue within the ignition. Confused and overheated simply trying to start the car and hope it stays running.it's that electrical issue that keeps saying yes enough voltage then nope can't have it. It's been proven not only by scanning but by reading and testing .
