I HAVE 16,000 MILES ON MY 2001 GRAND AM AND HAVE HAD IT IN TWICE FOR A LEAK IN THE HEATER CORE AND TWICE FOR WATER LEAKAGE FROM RAIN. ONCE AGAIN MY CAR HAD WATER IN IT. WENT TO DEALERSHIP FRIDAY 2-21-2003 AND THEY SAID I COULDN'T GET MY CAR IN UNTIL MARCH 3 BECAUSE THEY HAD SO MANY WITH THE SAME PROBLEM. I NEED MY CAR, SO I WENT HOME AND SUCKED ALL THE WATER OUT. THAT SAME NIGHT IT RAINED AGAIN, AND SURE ENOUGH, ABOUT 1/2 OF WATER ON THE FLOOR. SO NOW I HAVE A NEW CAR THAT SMELLS LIKE MOLD.THE OTHER THING IS THEY TOLD ME AFTER MY WARRANTY WAS UP I WOULD HAVE TO START PAYING FOR THE REPAIRS MYSELF. MY CAR IS ALREADY RUINED, AND IT SOUNDS LIKE THE PROBLEM CANNOT BE FIXED. THIS IS THE FOURTH TIME IT HAS LEAKED. WHAT SHOULD I DO? WHY DON'T THEY RECALL THEM IF IT IS DEFECT?

I HAVE OWNED MY 2001 GRAND AM SINCE THE LATER PART OF 2000 AND FOR THE PAST TWO AND HALF YEARS I HAVE HAD NOTHING BUT PROBLEMS WITH THE BARKES. I HAVE WENT THRU THREE SETS OF PADS AND IT HAS MADE A GRRINDING NOISE AFTER ABOUT TWO MONTHS OF OWNERSHIP. THE ABS LIGHT IS KNOW STARTING TO COME ON AND THIS CAR IS THE ONE MY WIFE USES ON A DAILY BASIS AND I AM WORRIED THAT DUE TO THE FREQUENCY OF BARKE PROBLEMS IT IS NOT SAFE FOR HER TO DRIVE. THE CAR ONLY HAS 41,000 MILES AND PARTLY DUE TO WE DO NOT TRUST THE VEHICLE AND DUE TO THE LOW BOOK VALUE OF THE CAR WE WILL LOSE IF WE TRY TO TRADE BUT ARE PUT INTO A PSOTION TO FOR KNOW HOLD ON TO IT.

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.
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.
CERTAIN MINIVANS, PASSENGER AND SPORT UTILITY VEHICLES FAIL TO COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 225, "CHILD RESTRAINT ANCHORAGE SYSTEM." THE OWNER'S MANUAL DOES NOT EXPLAIN THE MEANING OF THE LOCATION SYMBOLS FOR THE CHILD RESTRAINT LOWER UNIVERSAL ANCHORAGE SYSTEM.
Consequence & remedy
Consequence: THIS DOES NOT MEET THE REQUIREMENTS OF THE STANDARD.
Remedy: OWNERS WILL BE PROVIDED WITH A SUPPLEMENT FOR THEIR OWNER'S MANUAL. THIS SUPPLEMENT DESCRIBES AND SHOWS THE LOCATION SYMBOLS FOR THE CHILD RESTRAINT ANCHORS THAT ARE LOCATED IN THE VEHICLE AND ON THE CHILD RESTRAINT OR BOOSTER CUSHION. OWNER NOTIFICATION BEGAN AUGUST 18, 2003. OWNERS SHOULD CONTACT BUICK AT 1-866-608-8080, CADILLAC AT 1-866-982-2339, CHEVROLET AT 1-800-630-2438, GMC AT 1-866-996-9463, PONTIAC AT 1-800-620-7668, OR OLDSMOBILE AT 1-800-630-6537.
VEHICLE DESCRIPTION: CERTAIN PASSENGER VEHICLES EQUIPPED WITH MANUAL TRANSAXLES (RPO M86) FAIL TO COMPLY WITH THE REQUIREMENTS OF FMVSS NO. 114, "THEFT PROTECTION." WHEN A DRIVER ATTEMPTS TO SHIFT FROM 5TH GEAR TO REVERSE, A SHIFT INHIBITOR CAUSES THE TRANSMISSION TO BE MECHANICALLY IN 4TH GEAR EVEN THOUGH THE SHIFT LEVER INDICATES REVERSE GEAR.
Consequence & remedy
Consequence: IN THIS SITUATION, THE KEY CAN BE REMOVED FROM THE IGNITION WHILE THE TRANSMISSION IS IN A FORWARD GEAR, WHICH IS NOT PERMITTED BY THE STANDARD.
Remedy: DEALERS WILL DISABLE THE 5TH/REVERSE INHIBITOR BY REMOVING A RETAINING PIN AND REPLACE THE SHIFTER ASSEMBLY.
