I HAVE TWICE REPLACED THE INTAKE MANIFOLD GASKETS ON MY 2001 CHEVROLET MALIBU. BOTH TIMES IT HAS STARTED AS A SLOW SEEP FROM THE END OF THE ENGINE ON THE DRIVERS SIDE. AT FIRST WE DIDN'T HAVE ANY PUDDLES, JUST A LOW FLUID INDICATOR ALARM. THEN WE HAD INTERMITTANT PUDDLES. THE LATEST OCCURENCE INCLUDED A CATASTROPHIC FAILURE WITH ABOUT AN HALF A GALLON OF FLUID INTO THE ENGINE, AND IT WAS 200 MILES FROM HOME. WE WERE FORTUNATE THAT WE WERE NOT DRIVING WHEN THE FAILURE WAS DISCOVERED, SO WE DIDN'T HAVE TO REPLACE THE ENGINE. THE FIRST REPAIR OCCURED IN JANUARY 2005 AT 101K MILES, THIS ONE IN AUGUST 07 WITH 144K MILES. THE FIRST REPAIR WAS DONE AT AN ASCE SHOP AND COST $700, THIS ONE WAS AT A DEALER AND COST $1200. I DESCRIBED THE INCIDENT TO ANOTHER MECHANIC, AND HIS FIRST QUESTION WAS, "GM CAR?" IT IS QUITE COMMON AND WELL KNOWN TO MECHANICS.

Official recalls
2Jul 3, 2014
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.
Consequence & remedy
Consequence: 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.
Aug 28, 2003
CERTAIN PASSENGER VEHICLES HAVE HAZARD WARNING SWITCHES THAT MAY EXPERIENCE SOLDER JOINT CRACKING CAUSED BY RAPID TEMPERATURE TRANSITIONS AND THE SOLDERING PROCESS. IF SOLDER JOINT CRACKING OCCURS AND RESULTS IN AN OPEN CIRCUIT, THE TURN SIGNALS/HAZARD LAMPS BECOME INTERMITTENT OR INOPERATIVE.
Consequence & remedy
Consequence: WHEN THE TURN SIGNALS ARE INOPERATIVE, THE DRIVER CANNOT USE THEM TO SIGNAL INTENT TO TURN THAT COULD RESULT IN A CRASH.
Remedy: DEALERS WILL REPLACE THE HAZARD WARNING SWITCH. OWNER NOTIFICATION BEGAN ON FEBRUARY 5, 2004. OWNERS SHOULD CONTACT CHEVROLET AT 1-800-630-2438, PONTIAC AT 1-800-620-7668, OR OLDSMOBILE AT 1-800-630-6537.
