MY PROBLEM STARTED SUMMER OF 2008,I WAS DRIVING ON HIGHWAY12 TRAVELING 55MPH. I FELT AS IF MY CAR WAS LIFTING ITSELF OFF THE GROUND SEVERAL MINS LATER I HEARD A LOUD BOOM. AND WAS SLIGHTLY BLINDED BY THE SUNLIGHT. I THOUGHT I WAS HIT BY ANOTHER CAR. BUT IT WAS MY SUNROOF THAT CAME OFF. IT HAS BEEN WELL OVER A YEAR I STILL HAVE NOT BEEN ABLE TO HAVE SUNROOF REPAIRED. MOST REPAIR SHOPS REFER ME TO THE PONTIAC DEALER AS THEY HAVE NEVER HEARD OF A SUNROOF COMING OFF UNLESS DEFECTED. I CALLED THE PONTIAC DEALER IN STOCKTON, CA TWICE EACH TIME I WAS TOLD SUNROOFS FLY OFF ALL THE TIME, I COULD TAKE IT TO ANY REPAIR SHOP OF MY CHOICE OR SEE IF INSURANCE WILL COVER REPAIRS. I ASKED WHAT SHOPS THEY USED OR RECOMMEND EACH TIME AGENTS COULD NOT RECALL ANYTHING. I CALLED MY INSURANCE THEY TOO HAVE NEVER HEARD OF THIS, SINCE NOT FROM AN ACCIDENT OR NATURAL DISASTER I WOULD BE RESPONSIBLE FOR COST OF REPAIRS. I HAVE TWO SMALL CHILDREN WHO I TRANSPORT IN VEHICLE DRIVING WITHOUT A SUNROOF WAS VERY STRESSFUL AND NOT SAFE FOR THE HEALTH OF MY CHILDREN NOR MYSELF. AFTER THE RUN AROUND, TRYING TO TAPE DOWN EXPOSED AREA TO NO AVAIL, LOST OF HEARING. I DECIDED TO GO TO TAPS, THERE, THEY WERE ABLE TO CUT A PIECE OF HARD PLASTIC TO COVER TEMPORARILY. I FEEL AS A CONSUMER I HAVE BEEN GIVEN THE RUN AROUND AND I 'M AT A LOST FOR WHERE I CAN TAKE MY CAR LOCALLY TO HAVE SUNROOF REPAIRED PERMANENTLY. MY SECOND ISSUE IS WITH MY IGNITION LOCKS UP ON ME AND WILL NOT LET ME DRIVE.A SECURITY LIGHT THAT IS LIT UP AS WELL, AS I DO NOT HAVE A SECURITY SYSTEM, I CALLED DEALER I WAS TOLD IT MAY HAVE TO DO WITH MY KEY REMOTE, I STATED I DON'T HAVE KEY, I WAS THEN TOLD IT MAY BE I COPIED KEYS AND THE COPY IS NOT BEING READ BY CAR. I INFORMED THEM I USE THE ORIGINAL KEY FOR CAR I WAS GIVEN WHEN I PURCHASED CAR. THE DEALER DID NOT KNOW WHY AND REFERRED ME TO HAVE CAR CHECKED. I HAD MAINTENANCE DONE, EACH SHOP COULD NOT FIND ANYTHING OUT OF THE ORDINARY FOR THE PROBLEM. I'M DISAPPOINTED AND FRUSTRATED. *TR

THE TURN SIGNAL SWITCH MAKES A CLICKING NOISE EVEN AFTER THE TURN SIGNAL IS TURNED OFF. I HAVE TO "LIGHTLY" HOLD DOWN THE SWITCH TO SIGNAL A TURN. IF I TURN THE SIGNAL ON COMPLETELY, THE CLICKING NOISE WILL COME ON. I FIND MYSELF NOT USING MY TURN SIGNAL MUCH BECAUSE I AM AFRAID THE CLICKING NOISE WILL COME ON ALL OF THE TIME. THIS COULD CREATE A PROBLEM FOR SOMEONE BEHIND ME IF I AM NOT SIGNALING. I REALIZE THERE IS A RECALL FOR CERTAIN GRAND AM'S. EVEN THOUGH MINE IS A 2000, PONTIAC SAYS MY VEHICLE IS NOT ONE OF THE RECALL VEHICLES. YET, I EXPERIENCE THE SAME PROBLEM THAT APPEAR TO BE FOR THE RECALL. *TR

I SEE ON YOUR WEBSITE AND VARIOUS OTHERS THAT THIS PROBLEM INVOLVES A RECALL BY GM, HOWEVER WHEN I SPOKE TO THEM THEY TELL ME THAT IT HASN'T BEEN RECALLED. THERE WAS NOTHING THAT LED UP TO IT, JUST STARTED BEING A PROBLEM ONE DAY. I HAVE NOT HAD IT FIXED YET, AS I FEEL LIKE IT'S GM'S RESPONSIBILITY TO FIX IT. MY SECOND PROBLEM IS MY MANIFOLD INTAKE, WHICH IS CAUSING MY CAR TO LEAK COOLANT INTO THE ENGINE AND MAKING MY CAR OVERHEAT. I HAVE SEEN THAT THIS HAS BEEN A PROBLEM FOR THOUSANDS OF OWNERS AND GM IS DOING NOTHING ABOUT IT. I HAVE SPOKEN TO THEM AND THEY REFUSE TO FIX IT. THEIR DEALERSHIP WANTS TO CHARGE ME $1400 TO FIX IT, EVEN THOUGH IT IS OBVIOUSLY A PROBLEM. EVEN THOUGH I HAD ALREADY HAD THE PROBLEM DIAGNOSED THROUGH ANOTHER REPAIR SHOP, THEY SAID THEY WOULD NOT EVEN CONSIDER FIXING IT UNLESS I HAD IT DIAGNOSED THROUGH THEIR DEALER, WHICH COST ME $105 THAT I DON'T HAVE. I AM DISABLED, AND ON STATE DISABILITY AND I FEEL LIKE THEY COMPLETELY SCAMMED ME, NOT TO MENTION THAT NOW I HAVE AN INOPERABLE CAR AND HAVE NO WAY OF GETTING TO THE DOCTOR. NOTHING LED UP TO THE PROBLEM, IT LEAKS COOLANT CONSTANTLY AND NOW OVERHEATS ALL OF THE TIME, MAKING IT UNDRIVABLE. *TR

2000 PONTIAC GRAND AM, PLASTIC CONNECTOR USED TO ATTACH CRUISE CONTROL TO THROTTLE-BODY BROKE AND BECAME LODGED, RESULTING IN THE THROTTLE BEING HELD OPEN. AFTER TURNING A CORNER AND LETTING OFF THE GAS PEDAL THE CAR CONTINUED TO ACCELERATE. I APPLIED BRAKE WHICH PARTIALLY SLOWED THE CAR BUT NOT ENOUGH TO STOP. I WAS ABLE TO NAVIGATE THROUGH A RED LIGHT AT WHICH POINT I HAD TO PUT THE CAR IN NEUTRAL AND TURN THE KEY OFF TO COAST OUT OF THE WAY OF OTHER MOTORIST. AFTER FIGHTING TO GET THE CAR STOPPED AND STEERING INTO A PARKING LOT I WAS ABLE TO QUICKLY DETERMINE THE CAUSE. THE PLASTIC FITTING USED TO CONNECT THE CRUISE CONTROL WAS WEDGED BETWEEN THE BRACE AND THROTTLE HOLDING THE BUTTERFLY 3/4 OF THE WAY OPEN, WHICH WAS ROUGHLY 5K RPM. AFTER FIGHTING WITH THE THROTTLE AND PLASTIC I WAS ABLE TO FREE IT AND TIE THE CABLE OUT OF THE WAY. I SPOKE WITH A GM DEALERSHIP AND FOUND THAT THE PART # IS 22618777. I UNDERSTAND IF THIS WAS A FLUKE BUT WANTED TO GIVE SOME INFORMATION IN CASE IT HAPPENS TO SOMEONE ELSE. I KNOW MY EXPERIENCE COULD HAVE BEEN VERY BAD BUT WAS LUCKY TO AVOID ANY COLLISIONS. I JUST HOPE THE FACT THAT THERE WERE NO DEATHS OR INJURIES THAT THIS MATTER IS STILL TAKEN SERIOUSLY, MY MOTHER HAS THE EXACT SAME CAR AND I PLAN TO INSPECT HER ASSEMBLY THIS WEEKEND. *TR
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.
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.
VEHICLE DESCRIPTION: THESE VEHICLES DO NOT COMPLY WITH THE OCCUPANT PROTECTION REQUIREMENTS OF FMVSS NO. 201, "OCCUPANT PROTECTION IN INTERIOR IMPACT." THE CONSOLE COVER ON THESE VEHICLES DOES NOT STAY CLOSED WHEN A SPECIFIED VERTICAL LOAD IS APPLIED.
Consequence & remedy
Consequence: IN THE EVENT OF A CRASH, THE CONSOLE COVER COULD OPEN AND THE COVER OR ITEMS STORED UNDER IT COULD INJURE AN OCCUPANT.
Remedy: DEALERS WILL REPLACE THE CONSOLE LATCH MECHANISM.
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE BOLT THAT ATTACHES THE REAR SUSPENSION TRAILING ARM TO THE LEFT REAR KNUCKLE MAY NOT HAVE BEEN TIGHTENED TO SPECIFICATIONS DURING ASSEMBLY.
Consequence & remedy
Consequence: THE BOLT COULD BACK COMPLETELY OUT OF THE JOINT AFFECTING VEHICLE CONTROL.
Remedy: DEALERS WILL TIGHTEN THIS BOLT.

STRAINER TO FILTER FUEL FLOWING TO THE PUMP INLET.THIS FILTER CAN SOMETIMES BECOME CLOGGED, RESULTING IN A REDUCED FLOW OF FUEL TO THE ENGINE.GM HAS SUBSEQUENTLY MODIFIED THE STRAINERS TO REDUCE THIS RESTRICTION.ANALYSIS OF THE ODI COMPLAINT DATABASE SHOWS THAT DESPITE THESE RESTRICTIONS, THE SUBJECT VEHICLES STALL AT A RATE THAT IS COMPARABLE TO THOSE OF MANY PEER VEHICLES.ADDITIONALLY, NONE OF THE RELEVANT WARRANTY REPAIR RATES EXCEED 1% AT 36 MONTHS OF EXPOSURE.ONE RELATED CRASH INVOLVES A STALLED VEHICLE THAT WAS REAR-ENDED ON THE ROADWAY, WHILE THE REMAINDER INVOLVED MINOR COLLISIONS OR SCRAPES.THE SOLE INJURY CONSISTED OF BRUISING FROM A LOW SPEED FRONTAL CRASH. GIVEN THESE CIRCUMSTANCES, FURTHER EXPENDITURE OF AGENCY RESOURCES IS NOT JUSTIFIED IN THIS MATTER.THE PRELIMINARY EVALUATION IS THEREFORE CLOSED.THE CLOSING OF THIS INVESTIGATION DOES NOT CONSTITUTE A FINDING BY NHTSA THAT NO SAFETY-RELATED DEFECT EXISTS.THE AGENCY WILL TAKE FURTHER ACTION IN THE FUTURE IF WARRANTED.
