THE BRAKES ON THE OLDS ALERO HAVE A DESIGN FLAW IN THE BRAKES. THE ROTORS TEND TO OVERHEAT UNDER NORMAL DRIVING USE. IT WEARS THE PADS DOWN FASTER THAN THEY SHOULD, WARPS THE ROTORS SO THAT THEY HAVE TO BE TURNED EVERY SINGLE TIME YOU REPLACE THE PADS... AND I DO MEAN HAVE TO BE. THE ROTORS WILL QUICKLY LOSE THICKNESS, AND THE THINNER THEY ARE AFTER EACH TURN THE QUICKER THEY WILL WARP UNDER NORMAL USE. CONTACTING GENERAL MOTORS HAS ACCOMPLISHED NOTHING... DESPITE THE FACT THAT UNDER THE 2000 MODEL THEY HAD A TECHNICAL SERVICE BULLETIN (FRONT DISC BRAKE PULSATION (NEW ROTOR RUN-OUT SPECIFICATION AND CORRECTION METHOD) #00-05-23-002A) ISSUED FOR THE CAR. TO MY KNOWLEDGE GENERAL MOTORS HASN'T ALTERED THE DESIGN OF THE CAR SINCE IT'S INCEPTION WITH EXCEPTION OF COSMETIC CHANGES. THEY REFUSE TO ADMIT THERE'S A DESIGN FLAW IN THE BRAKES THAT FORCES THE CONSUMER TO EITHER PAY OUTRAGEOUS PRICES EACH AND EVERY TIME THEY NEED BRAKE PADS... OR DISCARD THE MANUFACTURERS WARRANTY AND PURCHASE AFTERMARKET BRAKE SOLUTIONS TO ELIMINATE THE ISSUE ENTIRELY. *NLM

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.
