2001 PONTIAC GRAND AM HAS HAD PROBLEMS WITH WINDOW MOTOR, TURN SIGNALS, AIR CONDITIONER, THE BRAKE SYSTEM, THE SECURITY SYSTEM AND VEHICLE WOULD NOT START. *MR THERE WAS STRANGE NOISE WHEN THE BRAKES WERE APPLIED AND WHEN MAKING A LEFT TURN. THE OTHER PROBLEMS WITH THE WINDOW MOTOR, TURN SIGNALS, AIR CONDITIONER WERE RESOLVED PER WARRANTY, BUT THE BRAKE SYSTEM PROBLEMS CONTINUED. THERE WERE TWO INSTANCES WITH THE FACTORY SECURITY SYSTEM. THE VEHICLE WOULD NOT START. THE VEHICLE WOULD JUST CRANK BUT NOT CATCH. THE SECURITY LIGHT STARTED TO FLASH. THE VEHICLE WAS TAKEN TO THE DEALER WHERE THEY RESET THE SYSTEM. A FEW MONTHS LATER, THE SECURITY SYSTEM LOCKED THE VEHICLE. THE CONSUMER FOUND THAT THE KEY SENSOR IN THE IGNITION SHORTED AND THE PASS LOCK MODULE WAS REPLACED AND RE-KEYED. *SC *JB

I HAVE A PONTIAC GRAND AM GT 2001 V6 AND IT HAS 3 MAJOR PROBLEMS. THE CAR HAS 52,000 MILES AND I HAVE HAD TO REPLACE THE ROTORS/BREAKS TWICE ALREADY. WHENEVER THE FRONT BRAKES ARE APPLIED THEY PULSATE AND DRAG THE CAR TO A STOP. BEST OF ALL ITS STARTING TO SHUDDER AGAIN WHEN I USE THE BREAKS. SO, SOON TO BE 3 TIMES IN ABOUT 3 YEARS. SECOND, THE SPEAKERS HAVE BLOWN 2 TIMES. I DONT UNDERSTAND WHY GM WOULD PUT SPEAKERS IN THE CAR THAT CANNOT HANDLE THE POWER FROM THE FACTORY RECIEVER. FINALLY, THE ENGINE COOLING PROBLEM. THE LOW COOLANT LIGHT WOULD TURN ON WHEN I STARTED THE CAR, THEN TURN OFF AFTER 10-30 SECONDS. THIS WENT ON FOR A WEEK OR TWO AND I BROUGHT IT IN TO GET CHECKED OUT. THEY TOLD ME THE DEX COOL COOLANT ATE THROUGH THE GASKETS, WHICH CAUSED THE LOSS OF COOLANT. ITS $800 TO GET IT FIXED. PLEASE DO SOMETHING, THIS CAR'S DESIGN IS FLAWED.*AK

Official recalls
4Jul 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.
Jul 15, 2003
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.
Nov 13, 2000
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.
